+~Gitaly, ~Platform, ~Prometheus, ~Release, and ~"UX".
 
 The descriptions on the [labels page][labels-page] explain what falls under the
 responsibility of each team.
 
+Within those team labels, we also have the ~backend and ~frontend labels to
+indicate if an issue needs backend work, frontend work, or both.
+
 Team labels are always capitalized so that they show up as the first label for
 any issue.

+# Installing Git
+

+> **Level:** beginner ||
+> **Author:** [Sean Packham](https://gitlab.com/SeanPackham) ||
+> **Publication date:** 2017/05/15
+
+To begin contributing to GitLab projects
+you will need to install the Git client on your computer.
+This article will show you how to install Git on macOS, Ubuntu Linux and Windows.
+
+## Install Git on macOS using the Homebrew package manager
+
+Although it is easy to use the version of Git shipped with macOS
+or install the latest version of Git on macOS by downloading it from the project website,
+we recommend installing it via Homebrew to get access to
+an extensive selection of dependancy managed libraries and applications.
+
+If you are sure you don't need access to any additional development libraries
+or don't have approximately 15gb of available disk space for Xcode and Homebrew
+use one of the the aforementioned methods.
+
+### Installing Xcode
+
+Xcode is needed by Homebrew to build dependencies.
+You can install [XCode](https://developer.apple.com/xcode/)
+through the macOS App Store.
+
+### Installing Homebrew
+
+Once Xcode is installed browse to the [Homebrew website](http://brew.sh/index.html)
+for the official Homebrew installation instructions.
+
+### Installing Git via Homebrew
+
+With Homebrew installed you are now ready to install Git.
+Open a Terminal and enter in the following command:
+
+```bash
+brew install git
+```
+
+Congratulations you should now have Git installed via Homebrew.
+Next read our article on [adding an SSH key to GitLab](../../ssh/README.md).
+
+## Install Git on Ubuntu Linux
+
+On Ubuntu and other Linux operating systems
+it is recommended to use the built in package manager to install Git.
+
+Open a Terminal and enter in the following commands
+to install the latest Git from the official Git maintained package archives:
+
+```bash
+sudo apt-add-repository ppa:git-core/ppa
+sudo apt-get update
+sudo apt-get install git
+```
+
+Congratulations you should now have Git installed via the Ubuntu package manager.
+Next read our article on [adding an SSH key to GitLab](../../ssh/README.md).
+
+## Installing Git on Windows from the Git website
+
+Browse to the [Git website](https://git-scm.com/) and download and install Git for Windows.
+Next read our article on [adding an SSH key to GitLab](../../ssh/README.md).

+# Analyze project code quality with Code Climate CLI
+
+This example shows how to run [Code Climate CLI][cli] on your code by using\
+GitLab CI and Docker.
+
+First, you need GitLab Runner with [docker-in-docker executor](../docker/using_docker_build.md#use-docker-in-docker-executor).
+
+Once you setup the Runner add new job to `.gitlab-ci.yml`:
+
+```yaml
+codeclimate:
+  image: docker:latest
+  variables:
+    DOCKER_DRIVER: overlay
+  services:
+    - docker:dind
+  script:
+    - docker pull codeclimate/codeclimate
+    - docker run --env CODECLIMATE_CODE="$PWD" --volume "$PWD":/code --volume /var/run/docker.sock:/var/run/docker.sock --volume /tmp/cc:/tmp/cc codeclimate/codeclimate init
+    - docker run --env CODECLIMATE_CODE="$PWD" --volume "$PWD":/code --volume /var/run/docker.sock:/var/run/docker.sock --volume /tmp/cc:/tmp/cc codeclimate/codeclimate analyze -f json > codeclimate.json
+  artifacts:
+    paths: [codeclimate.json]

+
+This will create a `codeclimate` job in your CI pipeline and will allow you to
+download and analyze the report artifact in JSON format.

-To set up a scheduled trigger:
-
-1. Check the **Schedule trigger (experimental)** checkbox
-1. Enter a cron value for the frequency of the trigger ([learn more about cron notation](http://www.nncron.ru/help/EN/working/cron-format.htm))
-1. Enter the timezone of the cron trigger ([see a list of timezones](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones))

-![Triggers Schedule create](img/trigger_schedule_updated_next_run_at.png)
-
-> **Notes**:
-- Those triggers won't be executed precicely. Because scheduled triggers are handled by Sidekiq, which runs according to its interval. For exmaple, if you set a trigger to be executed every minute (`* * * * *`) and the Sidekiq worker performs 00:00 and 12:00 o'clock every day (`0 */12 * * *`), then your trigger will be executed only 00:00 and 12:00 o'clock every day. To change the Sidekiq worker's frequency, you have to edit the `trigger_schedule_worker` value in `config/gitlab.yml` and restart GitLab. The Sidekiq worker's configuration on GiLab.com is able to be looked up at [here](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/config/gitlab.yml.example#L185).

+# Building a package for testing
+
+While developing a new feature or modifying an existing one, it is helpful if an
+installable package (or a docker image) containing those changes is available
+for testing. For this very purpose, a manual job is provided in the GitLab CI/CD
+pipeline that can be used to trigger a pipeline in the omnibus-gitlab repository
+that will create
+1. A deb package for Ubuntu 16.04, available as a build artifact, and
+2. A docker image, which is pushed to [Omnibus GitLab's container 
+registry](https://gitlab.com/gitlab-org/omnibus-gitlab/container_registry)
+(images titled `gitlab-ce` and `gitlab-ee` respectively and image tag is the
+commit which triggered the pipeline).
+
+When you push a commit to either the gitlab-ce or gitlab-ee project, the
+pipeline for that commit will have a `build-package` manual action you can
+trigger.
+
+![Manual actions](img/trigger_ss1.png)
+
+![Build package manual action](img/trigger_ss2.png)
+
+## Specifying versions of components
+
+If you want to create a package from a specific branch, commit or tag of any of
+the GitLab components (like GitLab Workhorse, Gitaly, GitLab Pages, etc.), you
+can specify the branch name, commit sha or tag in the component's respective
+`*_VERSION` file. For example, if you want to build a package that uses the
+branch `0-1-stable`, modify the content of `GITALY_SERVER_VERSION` to
+`0-1-stable` and push the commit. This will create a manual job that can be
+used to trigger the build.
+
+## Specifying the branch in omnibus-gitlab repository
+
+In scenarios where a configuration change is to be introduced and omnibus-gitlab
+repository already has the necessary changes in a specific branch, you can build
+a package against that branch through an environment variable named
+`OMNIBUS_BRANCH`. To do this, specify that environment variable with the name of
+the branch as value in `.gitlab-ci.yml` and push a commit. This will create a
+manual job that can be used to trigger the build.

 ### Vue.js
 
-
 #### Basic Rules
-- Only include one Vue.js component per file.
-- Export components as plain objects:
-
+1. The service has it's own file
+1. The store has it's own file
+1. Use a function in the bundle file to instantiate the Vue component:
   ```javascript
-  export default {
-    template: `<h1>I'm a component</h1>
-  }

+    // bad
+    class {
+      init() {
+        new Component({})

-- **Extensions**: Use `.vue` extension for Vue components.
-- **Reference Naming**: Use PascalCase for Vue components and camelCase for their instances:

+      components: {
+        componentName
+      },
+      render: createElement => createElement('component-name'),
+    }));
+  ```
 
+1. Don not use a singleton for the service or the store
   ```javascript
-  // bad
-  import cardBoard from 'cardBoard';
+    // bad
+    class Store {
+      constructor() {

-### Writing tests
+### Best practice
+
+#### Naming unit tests
+
+When writing describe test blocks to test specific functions/methods,
+please use the method name as the describe block name.
+
+```javascript
+// Good
+describe('methodName', () => {
+  it('passes', () => {
+    expect(true).toEqual(true);
+  });
+});
+
+// Bad
+describe('#methodName', () => {
+  it('passes', () => {
+    expect(true).toEqual(true);
+  });
+});
+
+// Bad
+describe('.methodName', () => {
+  it('passes', () => {
+    expect(true).toEqual(true);
+  });
+});
+```
+#### Testing Promises
+
+When testing Promises you should always make sure that the test is asynchronous and rejections are handled.
+Your Promise chain should therefore end with a call of the `done` callback and `done.fail` in case an error occurred.
+
+```javascript
+// Good
+it('tests a promise', (done) => {
+  promise
+    .then((data) => {
+      expect(data).toBe(asExpected);
+    })
+    .then(done)
+    .catch(done.fail);
+});
+
+// Good
+it('tests a promise rejection', (done) => {
+  promise
+    .then(done.fail)
+    .catch((error) => {
+      expect(error).toBe(expectedError);
+    })
+    .then(done)
+    .catch(done.fail);
+});
+
+// Bad (missing done callback)
+it('tests a promise', () => {
+  promise
+    .then((data) => {
+      expect(data).toBe(asExpected);
+    })
+});
+
+// Bad (missing catch)
+it('tests a promise', (done) => {
+  promise
+    .then((data) => {
+      expect(data).toBe(asExpected);
+    })
+    .then(done)
+});
+
+// Bad (use done.fail in asynchronous tests)
+it('tests a promise', (done) => {
+  promise
+    .then((data) => {
+      expect(data).toBe(asExpected);
+    })
+    .then(done)
+    .catch(fail)
+});
+
+// Bad (missing catch)
+it('tests a promise rejection', (done) => {
+  promise
+    .catch((error) => {
+      expect(error).toBe(expectedError);
+    })
+    .then(done)
+});
+```
+
+#### Stubbing
+
+For unit tests, you should stub methods that are unrelated to the current unit you are testing.
+If you need to use a prototype method, instantiate an instance of the class and call it there instead of mocking the instance completely.
+
+For integration tests, you should stub methods that will effect the stability of the test if they
+execute their original behaviour. i.e. Network requests.

+# Foreign Keys & Associations
+
+When adding an association to a model you must also add a foreign key. For
+example, say you have the following model:
+
+```ruby
+class User < ActiveRecord::Base
+  has_many :posts
+end
+```
+
+Here you will need to add a foreign key on column `posts.user_id`. This ensures
+that data consistency is enforced on database level. Foreign keys also mean that
+the database can very quickly remove associated data (e.g. when removing a
+user), instead of Rails having to do this.
+
+## Adding Foreign Keys In Migrations
+
+Foreign keys can be added concurrently using `add_concurrent_foreign_key` as
+defined in `Gitlab::Database::MigrationHelpers`. See the [Migration Style
+Guide](migration_style_guide.md) for more information.
+
+Keep in mind that you can only safely add foreign keys to existing tables after
+you have removed any orphaned rows. The method `add_concurrent_foreign_key`
+does not take care of this so you'll need to do so manually.
+
+## Cascading Deletes
+
+Every foreign key must define an `ON DELETE` clause, and in 99% of the cases
+this should be set to `CASCADE`.
+
+## Indexes
+
+When adding a foreign key in PostgreSQL the column is not indexed automatically,
+thus you must also add a concurrent index. Not doing so will result in cascading
+deletes being very slow.
+
+## Dependent Removals
+
+Don't define options such as `dependent: :destroy` or `dependent: :delete` when
+defining an association. Defining these options means Rails will handle the
+removal of data, instead of letting the database handle this in the most
+efficient way possible.
+
+In other words, this is bad and should be avoided at all costs:
+
+```ruby
+class User < ActiveRecord::Base
+  has_many :posts, dependent: :destroy
+end
+```
+
+Should you truly have a need for this it should be approved by a database
+specialist first.
+
+You should also not define any `before_destroy` or `after_destroy` callbacks on
+your models _unless_ absolutely required and only when approved by database
+specialists. For example, if each row in a table has a corresponding file on a
+file system it may be tempting to add a `after_destroy` hook. This however
+introduces non database logic to a model, and means we can no longer rely on
+foreign keys to remove the data as this would result in the filesystem data
+being left behind. In such a case you should use a service class instead that
+takes care of removing non database data.

+# Internationalization for GitLab
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/10669) in GitLab 9.2.
+
+For working with internationalization (i18n) we use
+[GNU gettext](https://www.gnu.org/software/gettext/) given it's the most used
+tool for this task and we have a lot of applications that will help us to work
+with it.
+
+## Setting up GitLab Development Kit (GDK)
+
+In order to be able to work on the [GitLab Community Edition](https://gitlab.com/gitlab-org/gitlab-ce) project we must download and
+configure it through [GDK](https://gitlab.com/gitlab-org/gitlab-development-kit), we can do it by following this [guide](https://gitlab.com/gitlab-org/gitlab-development-kit/blob/master/doc/set-up-gdk.md).
+
+Once we have the GitLab project ready we can start working on the
+translation of the project.
+
+## Tools
+
+We use a couple of gems:
+
+1. [`gettext_i18n_rails`](https://github.com/grosser/gettext_i18n_rails): this
+   gem allow us to translate content from models, views and controllers. Also
+   it gives us access to the following raketasks:
+    - `rake gettext:find`: Parses almost all the files from the
+      Rails application looking for content that has been marked for
+      translation. Finally, it updates the PO files with the new content that
+      it has found.
+    - `rake gettext:pack`: Processes the PO files and generates the
+      MO files that are binary and are finally used by the application.
+
+1. [`gettext_i18n_rails_js`](https://github.com/webhippie/gettext_i18n_rails_js):
+   this gem is useful to make the translations available in JavaScript. It
+   provides the following raketask:
+    - `rake gettext:po_to_json`: Reads the contents from the PO files and
+      generates JSON files containing all the available translations.
+
+1. PO editor: there are multiple applications that can help us to work with PO
+   files, a good option is [Poedit](https://poedit.net/download) which is
+   available for macOS, GNU/Linux and Windows.
+
+## Preparing a page for translation
+
+We basically have 4 types of files:
+
+1. Ruby files: basically Models and Controllers.
+1. HAML files: these are the view files.
+1. ERB files: used for email templates.
+1. JavaScript files: we mostly need to work with VUE JS templates.
+
+### Ruby files
+
+If there is a method or variable that works with a raw string, for instance:
+
+```ruby
+def hello
+  "Hello world!"
+end
+```
+
+Or:
+
+```ruby
+hello = "Hello world!"
+```
+
+You can easily mark that content for translation with:
+
+```ruby
+def hello
+  _("Hello world!")
+end
+```
+
+Or:
+
+```ruby
+hello = _("Hello world!")
+```
+
+### HAML files
+
+Given the following content in HAML:
+
+```haml
+%h1 Hello world!
+```
+
+You can mark that content for translation with:
+
+```haml
+%h1= _("Hello world!")
+```
+
+### ERB files
+
+Given the following content in ERB:
+
+```erb
+<h1>Hello world!</h1>
+```
+
+You can mark that content for translation with:
+
+```erb
+<h1><%= _("Hello world!") %></h1>
+```
+
+### JavaScript files
+
+In JavaScript we added the `__()` (double underscore parenthesis) function
+for translations.
+
+### Updating the PO files with the new content
+
+Now that the new content is marked for translation, we need to update the PO
+files with the following command:
+
+```sh
+bundle exec rake gettext:find
+```
+
+This command will update the `locale/**/gitlab.edit.po` file with the
+new content that the parser has found.
+
+New translations will be added with their default content and will be marked
+fuzzy. To use the translation, look for the `#, fuzzy` mention in `gitlab.edit.po`
+and remove it.
+
+Translations that aren't used in the source code anymore will be marked with
+`~#`; these can be removed to keep our translation files clutter-free.
+
+## Working with special content
+
+### Interpolation
+
+- In Ruby/HAML:
+
+    ```ruby
+    _("Hello %{name}") % { name: 'Joe' }
+    ```
+
+- In JavaScript: Not supported at this moment.
+
+### Plurals
+
+- In Ruby/HAML:
+
+    ```ruby
+    n_('Apple', 'Apples', 3) => 'Apples'
+    ```
+
+    Using interpolation:
+    ```ruby
+    n_("There is a mouse.", "There are %d mice.", size) % size
+    ```
+
+- In JavaScript:
+
+    ```js
+    n__('Apple', 'Apples', 3) => 'Apples'
+    ```
+
+    Using interpolation:
+
+    ```js
+    n__('Last day', 'Last %d days', 30) => 'Last 30 days'
+    ```
+
+### Namespaces
+
+Sometimes you need to add some context to the text that you want to translate
+(if the word occurs in a sentence and/or the word is ambiguous).
+
+- In Ruby/HAML:
+
+    ```ruby
+    s_('OpenedNDaysAgo|Opened')
+    ```
+
+    In case the translation is not found it will return `Opened`.
+
+- In JavaScript:
+
+    ```js
+    s__('OpenedNDaysAgo|Opened')
+    ```
+
+### Just marking content for parsing
+
+Sometimes there are some dynamic translations that can't be found by the
+parser when running `bundle exec rake gettext:find`. For these scenarios you can
+use the [`_N` method](https://github.com/grosser/gettext_i18n_rails/blob/c09e38d481e0899ca7d3fc01786834fa8e7aab97/Readme.md#unfound-translations-with-rake-gettextfind).
+
+There is also and alternative method to [translate messages from validation errors](https://github.com/grosser/gettext_i18n_rails/blob/c09e38d481e0899ca7d3fc01786834fa8e7aab97/Readme.md#option-a).
+
+## Adding a new language
+
+Let's suppose you want to add translations for a new language, let's say French.
+
+1. The first step is to register the new language in `lib/gitlab/i18n.rb`:
+
+    ```ruby
+    ...
+    AVAILABLE_LANGUAGES = {
+      ...,
+      'fr' => 'Français'
+    }.freeze
+    ...
+    ```
+
+1. Next, you need to add the language:
+
+    ```sh
+    bundle exec rake gettext:add_language[fr]
+    ```
+
+    If you want to add a new language for a specific region, the command is similar,
+    you just need to separate the region with an underscore (`_`). For example:
+
+    ```sh
+    bundle exec rake gettext:add_language[en_GB]
+    ```
+
+    Please note that you need to specify the region part in capitals.
+
+1. Now that the language is added, a new directory has been created under the
+   path: `locale/fr/`. You can now start using your PO editor to edit the PO file
+   located in: `locale/fr/gitlab.edit.po`.
+
+1. After you're done updating the translations, you need to process the PO files
+   in order to generate the binary MO files and finally update the JSON files
+   containing the translations:
+
+    ```sh
+    bundle exec rake gettext:compile
+    ```
+
+1. In order to see the translated content we need to change our preferred language
+   which can be found under the user's **Settings** (`/profile`).
+
+1. After checking that the changes are ok, you can proceed to commit the new files.
+   For example:
+
+    ```sh
+    git add locale/fr/ app/assets/javascripts/locale/fr/
+    git commit -m "Add French translations for Cycle Analytics page"
+    ```

+# Serializing Data
+
+**Summary:** don't store serialized data in the database, use separate columns
+and/or tables instead.
+
+Rails makes it possible to store serialized data in JSON, YAML or other formats.
+Such a field can be defined as follows:
+
+```ruby
+class Issue < ActiveRecord::Model
+  serialize :custom_fields
+end
+```
+
+While it may be tempting to store serialized data in the database there are many
+problems with this. This document will outline these problems and provide an
+alternative.
+
+## Serialized Data Is Less Powerful
+
+When using a relational database you have the ability to query individual
+fields, change the schema, index data and so forth. When you use serialized data
+all of that becomes either very difficult or downright impossible. While
+PostgreSQL does offer the ability to query JSON fields it is mostly meant for
+very specialized use cases, and not for more general use. If you use YAML in
+turn there's no way to query the data at all.
+
+## Waste Of Space
+
+Storing serialized data such as JSON or YAML will end up wasting a lot of space.
+This is because these formats often include additional characters (e.g. double
+quotes or newlines) besides the data that you are storing.
+
+## Difficult To Manage
+
+There comes a time where you will need to add a new field to the serialized
+data, or change an existing one. Using serialized data this becomes difficult
+and very time consuming as the only way of doing so is to re-write all the
+stored values. To do so you would have to:
+
+1. Retrieve the data
+1. Parse it into a Ruby structure
+1. Mutate it
+1. Serialize it back to a String
+1. Store it in the database
+
+On the other hand, if one were to use regular columns adding a column would be
+as easy as this:
+
+```sql
+ALTER TABLE table_name ADD COLUMN column_name type;
+```
+
+Such a query would take very little to no time and would immediately apply to
+all rows, without having to re-write large JSON or YAML structures.
+
+Finally, there comes a time when the JSON or YAML structure is no longer
+sufficient and you need to migrate away from it. When storing only a few rows
+this may not be a problem, but when storing millions of rows such a migration
+can easily take hours or even days to complete.
+
+## Relational Databases Are Not Document Stores
+
+When storing data as JSON or YAML you're essentially using your database as if
+it were a document store (e.g. MongoDB), except you're not using any of the
+powerful features provided by a typical RDBMS _nor_ are you using any of the
+features provided by a typical document store (e.g. the ability to index fields
+of documents with variable fields). In other words, it's a waste.
+
+## Consistent Fields
+
+One argument sometimes made in favour of serialized data is having to store
+widely varying fields and values. Sometimes this is truly the case, and then
+perhaps it might make sense to use serialized data. However, in 99% of the cases
+the fields and types stored tend to be the same for every row. Even if there is
+a slight difference you can still use separate columns and just not set the ones
+you don't need.
+
+## The Solution
+
+The solution is very simple: just use separate columns and/or separate tables.
+This will allow you to use all the features provided by your database, it will
+make it easier to manage and migrate the data, you'll conserve space, you can
+index the data efficiently and so forth.

+# GitLab Helm Chart
+> Officially supported cloud providers are Google Container Service and Azure Container Service.
+
+> Officially supported schedulers are Kubernetes and Terraform.
+
+The `gitlab` Helm chart deploys GitLab into your Kubernetes cluster.
+
+This chart includes the following:
+
+- Deployment using the [gitlab-ce](https://hub.docker.com/r/gitlab/gitlab-ce) or [gitlab-ee](https://hub.docker.com/r/gitlab/gitlab-ee) container image
+- ConfigMap containing the `gitlab.rb` contents that configure [Omnibus GitLab](https://docs.gitlab.com/omnibus/settings/configuration.html#configuration-options)
+- Persistent Volume Claims for Data, Config, Logs, and Registry Storage
+- A Kubernetes service
+- Optional Redis deployment using the [Redis Chart](https://github.com/kubernetes/charts/tree/master/stable/redis) (defaults to enabled)
+- Optional PostgreSQL deployment using the [PostgreSQL Chart](https://github.com/kubernetes/charts/tree/master/stable/postgresql) (defaults to enabled)
+- Optional Ingress (defaults to disabled)
+
+## Prerequisites
+
+- _At least_ 3 GB of RAM available on your cluster, in chunks of 1 GB. 41GB of storage and 2 CPU are also required.
+- Kubernetes 1.4+ with Beta APIs enabled
+- [Persistent Volume](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) provisioner support in the underlying infrastructure
+- The ability to point a DNS entry or URL at your GitLab install
+- The `kubectl` CLI installed locally and authenticated for the cluster
+- The Helm Client installed locally
+- The Helm Server (Tiller) already installed and running in the cluster, by running `helm init`
+- The GitLab Helm Repo [added to your Helm Client](index.md#add-the-gitlab-helm-repository)
+
+## Configuring GitLab
+
+Create a `values.yaml` file for your GitLab configuration. See the
+[Helm docs](https://github.com/kubernetes/helm/blob/master/docs/chart_template_guide/values_files.md)
+for information on how your values file will override the defaults.
+
+The default configuration can always be [found in the `values.yaml`](https://gitlab.com/charts/charts.gitlab.io/blob/master/charts/gitlab/values.yaml), in the chart repository.
+
+### Required configuration
+
+In order for GitLab to function, your config file **must** specify the following:
+
+- An `externalUrl` that GitLab will be reachable at.
+
+### Choosing GitLab Edition
+
+The Helm chart defaults to installing GitLab CE. This can be controlled by setting the `edition` variable in your values.
+
+Setting `edition` to GitLab Enterprise Edition (EE) in your `values.yaml`
+
+```yaml
+edition: EE
+
+externalUrl: 'http://gitlab.example.com'
+```
+
+### Choosing a different GitLab release version
+
+The version of GitLab installed is based on the `edition` setting (see [section](#choosing-gitlab-edition) above), and
+the value of the corresponding helm setting: `ceImage` or `eeImage`.
+
+```yaml
+## GitLab Edition
+## ref: https://about.gitlab.com/products/
+## - CE - Community Edition
+## - EE - Enterprise Edition - (requires license issued by GitLab Inc)
+##
+edition: CE
+
+## GitLab CE image
+## ref: https://hub.docker.com/r/gitlab/gitlab-ce/tags/
+##
+ceImage: gitlab/gitlab-ce:9.1.2-ce.0
+
+## GitLab EE image
+## ref: https://hub.docker.com/r/gitlab/gitlab-ee/tags/
+##
+eeImage: gitlab/gitlab-ee:9.1.2-ee.0
+```
+
+The different images can be found in the [gitlab-ce](https://hub.docker.com/r/gitlab/gitlab-ce/tags/) and [gitlab-ee](https://hub.docker.com/r/gitlab/gitlab-ee/tags/)
+repositories on Docker Hub
+
+> **Note:**
+There is no guarantee that other release versions of GitLab, other than what are
+used by default in the chart, will be supported by a chart install.
+
+
+### Custom Omnibus GitLab configuration
+
+In addition to the configuration options provided for GitLab in the Helm Chart, you can also pass any custom configuration
+that is valid for the [Omnibus GitLab Configuration](https://docs.gitlab.com/omnibus/settings/configuration.html).
+
+The setting to pass these values in is `omnibusConfigRuby`. It accepts any valid
+Ruby code that could used in the Omnibus `/etc/gitlab/gitlab.rb` file. In
+Kubernetes, the contents will be stored in a ConfigMap.
+
+Example setting:
+
+```yaml
+omnibusConfigRuby: |
+  unicorn['worker_processes'] = 2;
+  gitlab_rails['trusted_proxies'] = ["10.0.0.0/8","172.16.0.0/12","192.168.0.0/16"];
+```
+
+### Persistent storage
+
+By default, persistent storage is enabled for GitLab and the charts it depends
+on (Redis and PostgreSQL).
+
+Components can have their claim size set from your `values.yaml`, and each
+component allows you to optionally configure the `storageClass` variable so you
+can take advantage of faster drives on your cloud provider.
+
+Basic configuration:
+
+```yaml
+## Enable persistence using Persistent Volume Claims
+## ref: http://kubernetes.io/docs/user-guide/persistent-volumes/
+## ref: https://docs.gitlab.com/ce/install/requirements.html#storage
+##
+persistence:
+  ## This volume persists generated configuration files, keys, and certs.
+  ##
+  gitlabEtc:
+    enabled: true
+    size: 1Gi
+    ## If defined, volume.beta.kubernetes.io/storage-class: <storageClass>
+    ## Default: volume.alpha.kubernetes.io/storage-class: default
+    ##
+    # storageClass:
+    accessMode: ReadWriteOnce
+  ## This volume is used to store git data and other project files.
+  ## ref: https://docs.gitlab.com/omnibus/settings/configuration.html#storing-git-data-in-an-alternative-directory
+  ##
+  gitlabData:
+    enabled: true
+    size: 10Gi
+    ## If defined, volume.beta.kubernetes.io/storage-class: <storageClass>
+    ## Default: volume.alpha.kubernetes.io/storage-class: default
+    ##
+    # storageClass:
+    accessMode: ReadWriteOnce
+  gitlabRegistry:
+    enabled: true
+    size: 10Gi
+    ## If defined, volume.beta.kubernetes.io/storage-class: <storageClass>
+    ## Default: volume.alpha.kubernetes.io/storage-class: default
+    ##
+    # storageClass:
+
+  postgresql:
+    persistence:
+      # storageClass:
+      size: 10Gi
+  ## Configuration values for the Redis dependency.
+  ## ref: https://github.com/kubernetes/charts/blob/master/stable/redis/README.md
+  ##
+  redis:
+    persistence:
+      # storageClass:
+      size: 10Gi
+```
+
+>**Note:**
+You can make use of faster SSD drives by adding a [StorageClass] to your cluster
+and using the `storageClass` setting in the above config to the name of
+your new storage class.
+
+### Routing
+
+By default, the GitLab chart uses a service type of `LoadBalancer` which will
+result in the GitLab service being exposed externally using your cloud provider's
+load balancer.
+
+This field is configurable in your `values.yml` by setting the top-level
+`serviceType` field. See the [Service documentation][kube-srv] for more
+information on the possible values.
+
+#### Ingress routing
+
+Optionally, you can enable the Chart's ingress for use by an ingress controller
+deployed in your cluster.
+
+To enable the ingress, edit its section in your `values.yaml`:
+
+```yaml
+ingress:
+  ## If true, gitlab Ingress will be created
+  ##
+  enabled: true
+
+  ## gitlab Ingress hostnames
+  ## Must be provided if Ingress is enabled
+  ##
+  hosts:
+    - gitlab.example.com
+
+  ## gitlab Ingress annotations
+  ##
+  annotations:
+    kubernetes.io/ingress.class: nginx
+```
+
+You must also provide the list of hosts that the ingress will use. In order for
+you ingress controller to work with the GitLab Ingress, you will need to specify
+its class in an annotation.
+
+>**Note:**
+The Ingress alone doesn't expose GitLab externally. You need to have a Ingress controller setup to do that.
+Setting up an Ingress controller can be done by installing the `nginx-ingress` helm chart. But be sure
+to read the [documentation](https://github.com/kubernetes/charts/blob/master/stable/nginx-ingress/README.md)
+
+#### Preserving Source IPs
+
+If you are using the `LoadBalancer` serviceType you may run into issues where user IP addresses in the GitLab
+logs, and used in abuse throttling are not accurate. This is due to how Kubernetes uses source NATing on cluster nodes without endpoints.
+
+See the [Kubernetes documentation](https://kubernetes.io/docs/tutorials/services/source-ip/#source-ip-for-services-with-typeloadbalancer) for more information.
+
+To fix this you can add the following service annotation to your `values.yaml`
+
+```yaml
+## For minikube, set this to NodePort, elsewhere use LoadBalancer
+## ref: http://kubernetes.io/docs/user-guide/services/#publishing-services---service-types
+##
+serviceType: LoadBalancer
+
+## Optional annotations for gitlab service.
+serviceAnnotations:
+  service.beta.kubernetes.io/external-traffic: "OnlyLocal"
+```
+
+>**Note:**
+If you are using the ingress routing, you will likely also need to specify the annotation on the service for the ingress
+controller. For `nginx-ingress` you can check the
+[configuration documentation](https://github.com/kubernetes/charts/blob/master/stable/nginx-ingress/README.md#configuration)
+on how to add the annotation to the  `controller.service.annotations` array.
+
+>**Note:**
+When using the `nginx-ingress` controller on Google Container Engine (GKE), and using the `external-traffic` annotation,
+you will need to additionally set the `controller.kind` to be DaemonSet. Otherwise only pods running on the same node
+as the nginx controller will be able to reach GitLab. This may result in pods within your cluster not being able to reach GitLab.
+See the [Kubernetes documentation](https://kubernetes.io/docs/tutorials/services/source-ip/#source-ip-for-services-with-typeloadbalancer) and
+[nginx-ingress configuration documentation](https://github.com/kubernetes/charts/blob/master/stable/nginx-ingress/README.md#configuration)
+for more information.
+
+### External database
+
+You can configure the GitLab Helm chart to connect to an external PostgreSQL
+database.
+
+>**Note:**
+This is currently our recommended approach for a Production setup.
+
+To use an external database, in your `values.yaml`, disable the included
+PostgreSQL dependency, then configure access to your database:
+
+```yaml
+dbHost: "<reachable postgres hostname>"
+dbPassword: "<password for the user with access to the db>"
+dbUsername: "<user with read/write access to the database>"
+dbDatabase: "<database name on postgres to connect to for GitLab>"
+
+postgresql:
+  # Sets whether the PostgreSQL helm chart is used as a dependency
+  enabled: false
+```
+
+Be sure to check the GitLab documentation on how to
+[configure the external database](../requirements.md#postgresql-requirements)
+
+You can also configure the chart to use an external Redis server, but this is
+not required for basic production use:
+
+```yaml
+dbHost: "<reachable redis hostname>"
+dbPassword: "<password>"
+
+redis:
+  # Sets whether the Redis helm chart is used as a dependency
+  enabled: false
+```
+
+### Sending email
+
+By default, the GitLab container will not be able to send email from your cluster.
+In order to send email, you should configure SMTP settings in the
+`omnibusConfigRuby` section, as per the [GitLab Omnibus documentation](https://docs.gitlab.com/omnibus/settings/smtp.html).
+
+>**Note:**
+Some cloud providers restrict emails being sent out on SMTP, so you will have
+to use a SMTP service that is supported by your provider. See this
+[Google Cloud Platform page](https://cloud.google.com/compute/docs/tutorials/sending-mail/)
+as and example.
+
+Here is an example configuration for Mailgun SMTP support:
+
+```yaml
+omnibusConfigRuby: |
+  # This is example config of what you may already have in your omnibusConfigRuby object
+  unicorn['worker_processes'] = 2;
+  gitlab_rails['trusted_proxies'] = ["10.0.0.0/8","172.16.0.0/12","192.168.0.0/16"];
+
+  # SMTP settings
+  gitlab_rails['smtp_enable'] = true
+  gitlab_rails['smtp_address'] = "smtp.mailgun.org"
+  gitlab_rails['smtp_port'] = 2525 # High port needed for Google Cloud
+  gitlab_rails['smtp_authentication'] = "plain"
+  gitlab_rails['smtp_enable_starttls_auto'] = false
+  gitlab_rails['smtp_user_name'] = "postmaster@mg.your-mail-domain"
+  gitlab_rails['smtp_password'] = "you-password"
+  gitlab_rails['smtp_domain'] = "mg.your-mail-domain"
+```
+
+### HTTPS configuration
+
+To setup HTTPS access to your GitLab server, first you need to configure the
+chart to use the [ingress](#ingress-routing).
+
+GitLab's config should be updated to support [proxied SSL](https://docs.gitlab.com/omnibus/settings/nginx.html#supporting-proxied-ssl).
+
+In addition to having a Ingress Controller deployed and the basic ingress
+settings configured, you will also need to specify in the ingress settings
+which hosts to use HTTPS for.
+
+Make sure `externalUrl` now includes `https://` instead of `http://` in its
+value, and update the `omnibusConfigRuby` section:
+
+```yaml
+externalUrl: 'https://gitlab.example.com'
+
+omnibusConfigRuby: |
+  # This is example config of what you may already have in your omnibusConfigRuby object
+  unicorn['worker_processes'] = 2;
+  gitlab_rails['trusted_proxies'] = ["10.0.0.0/8","172.16.0.0/12","192.168.0.0/16"];
+
+  # These are the settings needed to support proxied SSL
+  nginx['listen_port'] = 80
+  nginx['listen_https'] = false
+  nginx['proxy_set_headers'] = {
+    "X-Forwarded-Proto" => "https",
+    "X-Forwarded-Ssl" => "on"
+  }
+
+ingress:
+  enabled: true
+  annotations:
+   kubernetes.io/ingress.class: nginx
+   # kubernetes.io/tls-acme: 'true' Annotation used for letsencrypt support
+
+  hosts:
+    - gitlab.example.com
+
+    ## gitlab Ingress TLS configuration
+    ## Secrets must be created in the namespace, and is not done for you in this chart
+    ##
+    tls:
+      - secretName: gitlab-tls
+        hosts:
+          - gitlab.example.com
+```
+
+You will need to create the named secret in your cluster, specifying the private
+and public certificate pair using the format outlined in the
+[ingress documentation](https://kubernetes.io/docs/concepts/services-networking/ingress/#tls).
+
+Alternatively, you can use the `kubernetes.io/tls-acme` annotation, and install
+the `kube-lego` chart to your cluster to have Let's Encrypt issue your
+certificate. See the [kube-lego documentation](https://github.com/kubernetes/charts/blob/master/stable/kube-lego/README.md)
+for more information.
+
+### Enabling the GitLab Container Registry
+
+The GitLab Registry is disabled by default but can be enabled by providing an
+external URL for it in the configuration. In order for the Registry to be easily
+used by GitLab CI and your Kubernetes cluster, you will need to set it up with
+a TLS certificate, so these examples will include the ingress settings for that
+as well. See the [HTTPS Configuration section](#https-configuration)
+for more explanation on some of these settings.
+
+Example config:
+
+```yaml
+externalUrl: 'https://gitlab.example.com'
+
+omnibusConfigRuby: |
+  # This is example config of what you may already have in your omnibusConfigRuby object
+  unicorn['worker_processes'] = 2;
+  gitlab_rails['trusted_proxies'] = ["10.0.0.0/8","172.16.0.0/12","192.168.0.0/16"];
+
+  registry_external_url 'https://registry.example.com';
+
+  # These are the settings needed to support proxied SSL
+  nginx['listen_port'] = 80
+  nginx['listen_https'] = false
+  nginx['proxy_set_headers'] = {
+    "X-Forwarded-Proto" => "https",
+    "X-Forwarded-Ssl" => "on"
+  }
+  registry_nginx['listen_port'] = 80
+  registry_nginx['listen_https'] = false
+  registry_nginx['proxy_set_headers'] = {
+    "X-Forwarded-Proto" => "https",
+    "X-Forwarded-Ssl" => "on"
+  }
+
+ingress:
+  enabled: true
+  annotations:
+   kubernetes.io/ingress.class: nginx
+   # kubernetes.io/tls-acme: 'true' Annotation used for letsencrypt support
+
+  hosts:
+    - gitlab.example.com
+    - registry.example.com
+
+    ## gitlab Ingress TLS configuration
+    ## Secrets must be created in the namespace, and is not done for you in this chart
+    ##
+    tls:
+      - secretName: gitlab-tls
+        hosts:
+          - gitlab.example.com
+          - registry.example.com
+```
+
+## Installing GitLab using the Helm Chart
+> You may see a temporary error message `SchedulerPredicates failed due to PersistentVolumeClaim is not bound` while storage provisions. Once the storage provisions, the pods will automatically restart. This may take a couple minutes depending on your cloud provider. If the error persists, please review the [prerequisites](#prerequisites) to ensure you have enough RAM, CPU, and storage.
+
+Once you [have configured](#configuration) GitLab in your `values.yml` file,
+run the following:
+
+```bash
+helm install --namespace <NAMESPACE> --name gitlab -f <CONFIG_VALUES_FILE> gitlab/gitlab
+```
+
+where:
+
+- `<NAMESPACE>` is the Kubernetes namespace where you want to install GitLab.
+- `<CONFIG_VALUES_FILE>` is the path to values file containing your custom
+  configuration. See the [Configuration](#configuration) section to create it.
+
+## Updating GitLab using the Helm Chart
+
+Once your GitLab Chart is installed, configuration changes and chart updates
+should we done using `helm upgrade`
+
+```bash
+helm upgrade --namespace <NAMESPACE> -f <CONFIG_VALUES_FILE> <RELEASE-NAME> gitlab/gitlab
+```
+
+where:
+
+- `<NAMESPACE>` is the Kubernetes namespace where GitLab is installed.
+- `<CONFIG_VALUES_FILE>` is the path to values file containing your custom
+  [configuration] (#configuration).
+- `<RELEASE-NAME>` is the name you gave the chart when installing it.
+  In the [Install section](#installing) we called it `gitlab`.
+
+## Uninstalling GitLab using the Helm Chart
+
+To uninstall the GitLab Chart, run the following:
+
+```bash
+helm delete --namespace <NAMESPACE> <RELEASE-NAME>
+```
+
+where:
+
+- `<NAMESPACE>` is the Kubernetes namespace where GitLab is installed.
+- `<RELEASE-NAME>` is the name you gave the chart when installing it.
+  In the [Install section](#installing) we called it `gitlab`.

+
+The `gitlab-runner` Helm chart deploys a GitLab Runner instance into your
+Kubernetes cluster.
+
+This chart configures the Runner to:
+
+- Run using the GitLab Runner [Kubernetes executor](https://docs.gitlab.com/runner/install/kubernetes.html)
+- For each new job it receives from [GitLab CI](https://about.gitlab.com/features/gitlab-ci-cd/), it will provision a

+
+## Prerequisites
+
+- Your GitLab Server's API is reachable from the cluster
+- Kubernetes 1.4+ with Beta APIs enabled

+
+## Configuring GitLab Runner using the Helm Chart
+
+Create a `values.yaml` file for your GitLab Runner configuration. See [Helm docs](https://github.com/kubernetes/helm/blob/master/docs/chart_template_guide/values_files.md)
+for information on how your values file will override the defaults.
+
+The default configuration can always be found in the [values.yaml](https://gitlab.com/charts/charts.gitlab.io/blob/master/charts/gitlab-runner/values.yaml) in the chart repository.
+
+### Required configuration
+
+In order for GitLab Runner to function, your config file **must** specify the following:
+
+ - `gitlabURL`  - the GitLab Server URL (with protocol) to register the runner against
+ - `runnerRegistrationToken` - The Registration Token for adding new Runners to the GitLab Server. This must be
+    retrieved from your GitLab Instance. See the [GitLab Runner Documentation](../../ci/runners/README.md#creating-and-registering-a-runner) for more information.
+
+### Other configuration
+
+The rest of the configuration is [documented in the `values.yaml`](https://gitlab.com/charts/charts.gitlab.io/blob/master/charts/gitlab-runner/values.yaml) in the chart repository.

+### Running Docker-in-Docker containers with GitLab Runners
+
+See [Running Privileged Containers for the Runners](#running-privileged-containers-for-the-runners) for how to enable it,
+and the [GitLab CI Runner documentation](https://docs.gitlab.com/runner/executors/kubernetes.html#using-docker-in-your-builds) on running dind.
+
+### Running privileged containers for the Runners
+
+You can tell the GitLab Runner to run using privileged containers. You may need
+this enabled if you need to use the Docker executable within your GitLab CI jobs.
+
+This comes with several risks that you can read about in the
+[GitLab CI Runner documentation](https://docs.gitlab.com/runner/executors/kubernetes.html#using-docker-in-your-builds).
+
+If you are okay with the risks, and your GitLab CI Runner instance is registered
+against a specific project in GitLab that you trust the CI jobs of, you can
+enable privileged mode in `values.yaml`:
+
+```yaml
+runners:
+  ## Run all containers with the privileged flag enabled
+  ## This will allow the docker:dind image to run if you need to run Docker
+  ## commands. Please read the docs before turning this on:
+  ## ref: https://docs.gitlab.com/runner/executors/kubernetes.html#using-docker-dind
+  ##
+  privileged: true
+```
+
+## Installing GitLab Runner using the Helm Chart
+
+Once you [have configured](#configuration) GitLab Runner in your `values.yml` file,
+run the following:
+
+```bash
+helm install --namepace <NAMEPACE> --name gitlab-runner -f <CONFIG_VALUES_FILE> gitlab/gitlab-runner
+```
+
+- `<NAMESPACE>` is the Kubernetes namespace where you want to install the GitLab Runner.
+- `<CONFIG_VALUES_FILE>` is the path to values file containing your custom configuration. See the
+  [Configuration](#configuration) section to create it.
+
+## Updating GitLab Runner using the Helm Chart
+
+Once your GitLab Runner Chart is installed, configuration changes and chart updates should we done using `helm upgrade`
+
+```bash
+helm upgrade --namepace <NAMEPACE> -f <CONFIG_VALUES_FILE> <RELEASE-NAME> gitlab/gitlab-runner
+```
+
+Where:
+- `<NAMESPACE>` is the Kubernetes namespace where GitLab Runner is installed
+- `<CONFIG_VALUES_FILE>` is the path to values file containing your custom configuration. See the
+  [Configuration](#configuration) section to create it.
+- `<RELEASE-NAME>` is the name you gave the chart when installing it.
+  In the [Install section](#installing) we called it `gitlab-runner`.
+
+## Uninstalling GitLab Runner using the Helm Chart
+
+To uninstall the GitLab Runner Chart, run the following:
+
+```bash
+helm delete --namespace <NAMESPACE> <RELEASE-NAME>
+```
+
+where:
+
+- `<NAMESPACE>` is the Kubernetes namespace where GitLab Runner is installed
+- `<RELEASE-NAME>` is the name you gave the chart when installing it.

+# Installing GitLab on Kubernetes
+> Officially supported cloud providers are Google Container Service and Azure Container Service.
+
+> Officially supported schedulers are Kubernetes and Terraform.
+
+The easiest method to deploy GitLab in [Kubernetes](https://kubernetes.io/) is
+to take advantage of the official GitLab Helm charts. [Helm] is a package
+management tool for Kubernetes, allowing apps to be easily managed via their
+Charts. A [Chart] is a detailed description of the application including how it
+should be deployed, upgraded, and configured.
+
+The GitLab Helm repository is located at https://charts.gitlab.io.
+You can report any issues related to GitLab's Helm Charts at
+https://gitlab.com/charts/charts.gitlab.io/issues.
+Contributions and improvements are also very welcome.
+
+## Prerequisites
+
+To use the charts, the Helm tool must be installed and initialized. The best
+place to start is by reviewing the [Helm Quick Start Guide][helm-quick].
+
+## Add the GitLab Helm repository
+
+Once Helm has been installed, the GitLab chart repository must be added:
+
+```bash
+helm repo add gitlab https://charts.gitlab.io
+```
+
+After adding the repository, Helm must be re-initialized:
+
+```bash
+helm init
+```
+
+## Using the GitLab Helm Charts
+
+GitLab makes available two Helm Charts, one for the GitLab server and another
+for the Runner. More detailed information on installing and configuring each
+Chart can be found below:

+### GitHub Enterprise with Self-Signed Certificate
+
+If you are attempting to import projects from GitHub Enterprise with a self-signed
+certificate and the imports are failing, you will need to disable SSL verification.
+It should be disabled by adding `verify_ssl` to `false` in the provider configuration
+and changing the global Git `sslVerify` option to `false` in the GitLab server.
+
+For omnibus package:
+
+```ruby
+  gitlab_rails['omniauth_providers'] = [
+    {

+      "verify_ssl" => false,
+      "args" => { "scope" => "user:email" }
+    }
+  ]
+```
+
+You will also need to disable Git SSL verification on the server hosting GitLab.
+
+```ruby
+omnibus_gitconfig['system'] = { "http" => ["sslVerify = false"] }
+```
+
+For installation from source:

+top left corner of GitLab (below the menu bar).
+
+If the highest number stable branch is unclear please check the
+[GitLab Blog](https://about.gitlab.com/blog/archives.html) for installation

+
+### 1. Stop server
+
+```bash
+sudo service gitlab stop
+```
+
+### 2. Backup
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
+```
+
+### 3. Update Ruby
+
+NOTE: GitLab 9.0 and higher only support Ruby 2.3.x and dropped support for Ruby 2.1.x. Be
+sure to upgrade your interpreter if necessary.
+
+You can check which version you are running with `ruby -v`.
+
+Download and compile Ruby:
+
+```bash
+mkdir /tmp/ruby && cd /tmp/ruby
+curl --remote-name --progress https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.3.tar.gz

+cd ruby-2.3.3
+./configure --disable-install-rdoc
+make
+sudo make install
+```
+
+Install Bundler:
+
+```bash
+sudo gem install bundler --no-ri --no-rdoc
+```
+
+### 4. Update Node
+
+GitLab now runs [webpack](http://webpack.js.org) to compile frontend assets and
+it has a minimum requirement of node v4.3.0.
+
+You can check which version you are running with `node -v`. If you are running
+a version older than `v4.3.0` you will need to update to a newer version.  You
+can find instructions to install from community maintained packages or compile
+from source at the nodejs.org website.
+
+<https://nodejs.org/en/download/>
+
+
+Since 8.17, GitLab requires the use of yarn `>= v0.17.0` to manage
+JavaScript dependencies.
+
+```bash
+curl --location https://yarnpkg.com/install.sh | bash -
+```
+
+More information can be found on the [yarn website](https://yarnpkg.com/en/docs/install).
+
+### 5. Get latest code
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git fetch --all
+sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically
+```
+
+For GitLab Community Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 9-2-stable
+```
+
+OR
+
+For GitLab Enterprise Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 9-2-stable-ee
+```
+
+### 6. Update gitlab-shell
+
+```bash
+cd /home/git/gitlab-shell
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_SHELL_VERSION)
+sudo -u git -H bin/compile
+```
+
+### 7. Update gitlab-workhorse
+
+Install and compile gitlab-workhorse. This requires
+[Go 1.5](https://golang.org/dl) which should already be on your system from
+GitLab 8.1. GitLab-Workhorse uses [GNU Make](https://www.gnu.org/software/make/).
+If you are not using Linux you may have to run `gmake` instead of
+`make` below.
+
+```bash
+cd /home/git/gitlab-workhorse
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_WORKHORSE_VERSION)
+sudo -u git -H make
+```
+
+### 8. Update configuration files
+
+#### New configuration options for `gitlab.yml`
+
+There might be configuration options available for [`gitlab.yml`][yaml]. View them with the command below and apply them manually to your current `gitlab.yml`:
+
+```sh
+cd /home/git/gitlab
+
+git diff origin/9-1-stable:config/gitlab.yml.example origin/9-2-stable:config/gitlab.yml.example
+```
+
+#### Nginx configuration
+
+Ensure you're still up-to-date with the latest NGINX configuration changes:
+
+```sh
+cd /home/git/gitlab
+
+# For HTTPS configurations
+git diff origin/9-1-stable:lib/support/nginx/gitlab-ssl origin/9-2-stable:lib/support/nginx/gitlab-ssl
+
+# For HTTP configurations
+git diff origin/9-1-stable:lib/support/nginx/gitlab origin/9-2-stable:lib/support/nginx/gitlab
+```
+
+If you are using Strict-Transport-Security in your installation to continue using it you must enable it in your Nginx
+configuration as GitLab application no longer handles setting it.
+
+If you are using Apache instead of NGINX please see the updated [Apache templates].
+Also note that because Apache does not support upstreams behind Unix sockets you

+#### SMTP configuration
+
+If you're installing from source and use SMTP to deliver mail, you will need to add the following line
+to config/initializers/smtp_settings.rb:
+
+```ruby

+```
+
+**MySQL installations**: Run through the `MySQL strings limits` and `Tables and data conversion to utf8mb4` [tasks](../install/database_mysql.md).
+
+### 10. Optional: install Gitaly
+
+Gitaly is still an optional component of GitLab. If you want to save time
+during your 9.2 upgrade **you can skip this step**.
+
+If you have not yet set up Gitaly then follow [Gitaly section of the installation
+guide](../install/installation.md#install-gitaly).
+
+#### Compile Gitaly
+
+```shell
+cd /home/git/gitaly
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITALY_SERVER_VERSION)
+sudo -u git -H make
+```
+
+### 11. Start application
+
+```bash
+sudo service gitlab start
+sudo service nginx restart
+```
+
+### 12. Check application status
+
+Check if GitLab and its environment are configured correctly:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
+```
+
+To make sure you didn't miss anything run a more thorough check:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
+```
+
+If all items are green, then congratulations, the upgrade is complete!
+
+## Things went south? Revert to previous version (9.1)
+
+### 1. Revert the code to the previous version
+
+Follow the [upgrade guide from 9.0 to 9.1](9.0-to-9.1.md), except for the
+database migration (the backup is already migrated to the previous version).
+
+### 2. Restore from the backup
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production
+```
+
+If you have more than one backup `*.tar` file(s) please add `BACKUP=timestamp_of_backup` to the command above.

+# From 9.2 to 9.3
+
+Make sure you view this update guide from the tag (version) of GitLab you would
+like to install. In most cases this should be the highest numbered production
+tag (without rc in it). You can select the tag in the version dropdown at the
+top left corner of GitLab (below the menu bar).
+
+If the highest number stable branch is unclear please check the
+[GitLab Blog](https://about.gitlab.com/blog/archives.html) for installation
+guide links by version.
+
+### 1. Stop server
+
+```bash
+sudo service gitlab stop
+```
+
+### 2. Backup
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
+```
+
+### 3. Update Ruby
+
+NOTE: GitLab 9.0 and higher only support Ruby 2.3.x and dropped support for Ruby 2.1.x. Be
+sure to upgrade your interpreter if necessary.
+
+You can check which version you are running with `ruby -v`.
+
+Download and compile Ruby:
+
+```bash
+mkdir /tmp/ruby && cd /tmp/ruby
+curl --remote-name --progress https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.3.tar.gz
+echo '1014ee699071aa2ddd501907d18cbe15399c997d ruby-2.3.3.tar.gz' | shasum -c - && tar xzf ruby-2.3.3.tar.gz
+cd ruby-2.3.3
+./configure --disable-install-rdoc
+make
+sudo make install
+```
+
+Install Bundler:
+
+```bash
+sudo gem install bundler --no-ri --no-rdoc
+```
+
+### 4. Update Node
+
+GitLab now runs [webpack](http://webpack.js.org) to compile frontend assets and
+it has a minimum requirement of node v4.3.0.
+
+You can check which version you are running with `node -v`. If you are running
+a version older than `v4.3.0` you will need to update to a newer version.  You
+can find instructions to install from community maintained packages or compile
+from source at the nodejs.org website.
+
+<https://nodejs.org/en/download/>
+
+
+Since 8.17, GitLab requires the use of yarn `>= v0.17.0` to manage
+JavaScript dependencies.
+
+```bash
+curl --location https://yarnpkg.com/install.sh | bash -
+```
+
+More information can be found on the [yarn website](https://yarnpkg.com/en/docs/install).
+
+### 5. Get latest code
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git fetch --all
+sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically
+```
+
+For GitLab Community Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 9-3-stable
+```
+
+OR
+
+For GitLab Enterprise Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 9-3-stable-ee
+```
+
+### 6. Update gitlab-shell
+
+```bash
+cd /home/git/gitlab-shell
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_SHELL_VERSION)
+sudo -u git -H bin/compile
+```
+
+### 7. Update gitlab-workhorse
+
+Install and compile gitlab-workhorse. This requires
+[Go 1.5](https://golang.org/dl) which should already be on your system from
+GitLab 8.1. GitLab-Workhorse uses [GNU Make](https://www.gnu.org/software/make/).
+If you are not using Linux you may have to run `gmake` instead of
+`make` below.
+
+```bash
+cd /home/git/gitlab-workhorse
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_WORKHORSE_VERSION)
+sudo -u git -H make
+```
+
+### 8. Update Gitaly
+
+If you have not yet set up Gitaly then follow [Gitaly section of the installation
+guide](../install/installation.md#install-gitaly).
+
+#### Compile Gitaly
+
+```shell
+cd /home/git/gitaly
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITALY_SERVER_VERSION)
+sudo -u git -H make
+```
+
+### 9. Update configuration files
+
+#### New configuration options for `gitlab.yml`
+
+There might be configuration options available for [`gitlab.yml`][yaml]. View them with the command below and apply them manually to your current `gitlab.yml`:
+
+```sh
+cd /home/git/gitlab
+
+git diff origin/9-2-stable:config/gitlab.yml.example origin/9-3-stable:config/gitlab.yml.example
+```
+
+#### Nginx configuration
+
+Ensure you're still up-to-date with the latest NGINX configuration changes:
+
+```sh
+cd /home/git/gitlab
+
+# For HTTPS configurations
+git diff origin/9-2-stable:lib/support/nginx/gitlab-ssl origin/9-3-stable:lib/support/nginx/gitlab-ssl
+
+# For HTTP configurations
+git diff origin/9-2-stable:lib/support/nginx/gitlab origin/9-3-stable:lib/support/nginx/gitlab
+```
+
+If you are using Strict-Transport-Security in your installation to continue using it you must enable it in your Nginx
+configuration as GitLab application no longer handles setting it.
+
+If you are using Apache instead of NGINX please see the updated [Apache templates].
+Also note that because Apache does not support upstreams behind Unix sockets you
+will need to let gitlab-workhorse listen on a TCP port. You can do this
+via [/etc/default/gitlab].

+# Closing Issues
+
+Please read through the [GitLab Issue Documentation](index.md) for an overview on GitLab Issues.
+
+## Directly
+
+Whenever you decide that's no longer need for that issue,
+close the issue using the close button:
+
+![close issue - button](img/button_close_issue.png)
+
+## Via Merge Request
+
+When a merge request resolves the discussion over an issue, you can
+make it close that issue(s) when merged.
+
+All you need is to use a [keyword](automatic_issue_closing.md)
+accompanying the issue number, add to the description of that MR.
+
+In this example, the keyword "closes" prefixing the issue number will create a relationship
+in such a way that the merge request will close the issue when merged. 
+
+Mentioning various issues in the same line also works for this purpose:
+
+```md
+Closes #333, #444, #555 and #666
+```
+
+If the issue is in a different repository rather then the MR's,
+add the full URL for that issue(s):
+
+```md
+Closes #333, #444, and https://gitlab.com/<username>/<projectname>/issues/<xxx>
+```
+
+All the following keywords will produce the same behaviour:
+
+- Close, Closes, Closed, Closing, close, closes, closed, closing
+- Fix, Fixes, Fixed, Fixing, fix, fixes, fixed, fixing
+- Resolve, Resolves, Resolved, Resolving, resolve, resolves, resolved, resolving
+
+![merge request closing issue when merged](img/merge_request_closes_issue.png)
+
+If you use any other word before the issue number, the issue and the MR will
+link to each other, but the MR will NOT close the issue(s) when merged.
+
+![mention issues in MRs - closing and related](img/closing_and_related_issues.png)
+
+## From the Issue Board
+
+You can close an issue from [Issue Boards](../issue_board.md) by draging an issue card
+from its list and dropping into **Closed**.
+
+![close issue from the Issue Board](img/close_issue_from_board.gif)
+
+## Customizing the issue closing patern
+
+Alternatively, a GitLab **administrator** can
+[customize the issue closing patern](../../../administration/issue_closing_pattern.md).

+# Crosslinking Issues
+
+Please read through the [GitLab Issue Documentation](index.md) for an overview on GitLab Issues.
+
+## From Commit Messages
+
+Every time you mention an issue in your commit message, you're creating
+a relationship between the two stages of the development workflow: the
+issue itself and the first commit related to that issue.
+
+If the issue and the code you're committing are both in the same project,
+you simply add `#xxx` to the commit message, where `xxx` is the issue number.
+If they are not in the same project, you can add the full URL to the issue
+(`https://gitlab.com/<username>/<projectname>/issues/<xxx>`).
+
+```shell
+git commit -m "this is my commit message. Ref #xxx"
+```
+
+or
+
+```shell
+git commit -m "this is my commit message. Related to https://gitlab.com/<username>/<projectname>/issues/<xxx>"
+```
+
+Of course, you can replace `gitlab.com` with the URL of your own GitLab instance.
+
+**Note:** Linking your first commit to your issue is going to be relevant
+for tracking your process far ahead with
+[GitLab Cycle Analytics](https://about.gitlab.com/features/cycle-analytics/)).
+It will measure the time taken for planning the implementation of that issue,
+which is the time between creating an issue and making the first commit.
+
+## From Related Issues
+
+Mentioning related issues in merge requests and other issues is useful
+for your team members and collaborators to know that there are opened
+issues around that same idea.
+
+You do that as explained above, when
+[mentioning an issue from a commit message](#from-commit-messages).
+
+When mentioning the issue "A" in a issue "B", the issue "A" will also
+display a notification in its tracker. The same is valid for mentioning
+issues in merge requests.
+
+![issue mentioned in issue](img/mention_in_issue.png)
+
+## From Merge Requests
+
+Mentioning issues in merge request comments work exactly the same way
+they do for [related issues](#from-related-issues). 
+
+When you mention an issue in a merge request description, you can either
+[close the issue as soon as the merge request is merged](closing_issues.md#via-merge-request),
+or simply link both issue and merge request as described in the
+[closing issues documentation](closing_issues.md#from-related-issues).
+
+![issue mentioned in MR](img/mention_in_merge_request.png)
+
+### Close an issue by merging a merge request
+
+To [close an issue when a merge request is merged](closing_issues.md#via-merge-request), use the [automatic issue closing patern](automatic_issue_closing.md).

+# GitLab Issues Documentation
+
+The GitLab Issue Tracker is an advanced and complete tool
+for tracking the evolution of a new idea or the process
+of solving a problem.
+
+It allows you, your team, and your collaborators to share
+and discuss proposals, before and while implementing them.
+
+Issues and the GitLab Issue Tracker are available in all
+[GitLab Products](https://about.gitlab.com/products/) as
+part of the [GitLab Workflow](https://about.gitlab.com/2016/10/25/gitlab-workflow-an-overview/).
+
+## Use-Cases
+
+Issues can have endless applications. Just to exemplify, these are
+some cases for which creating issues are most used:
+
+- Discussing the implementation of a new idea
+- Submitting feature proposals
+- Asking questions
+- Reporting bugs and malfunction
+- Obtaining support

+# GitLab Issues Functionalities
+
+Please read through the [GitLab Issue Documentation](index.md) for an overview on GitLab Issues.
+
+## Issues Functionalities
+
+The image bellow illustrates how an issue looks like:
+
+![Issue view](img/issues_main_view_numbered.jpg)
+
+You can find all the information on that issue on one screen.
+
+### Issue screen
+
+An issue starts with its status (open or closed), followed by its author,
+and includes many other functionalities, numbered on the image above to
+explain what they mean, one by one.
+
+Many of the elements of the issue screen refresh automatically, such as the title and description, when they are changed by another user.
+Comments and system notes also appear automatically in response to various actions and content updates.
+
+#### 1. New Issue, close issue, edit
+
+- New issue: create a new issue in the same project
+- Close issue: close this issue
+- Edit: edit the same fields available when you create an issue.
+
+#### 2. Todos
+
+- Add todo: add that issue to your [GitLab Todo](../../../workflow/todos.html) list
+- Mark done: mark that issue as done (reflects on the Todo list)
+
+#### 3. Assignee
+
+Whenever someone starts to work on an issue, it can be assigned
+to that person. The assignee can be changed as much as needed.
+The idea is that the assignee is responsible for that issue until
+it's reassigned to someone else to take it from there.
+
+> **Tip:**
+if a user is not member of that project, it can only be
+assigned to them if they created the issue themselves.
+
+##### 3.1. Multiple Assignees (EES/EEP)
+
+Issue Weights are only available in [GitLab Enterprise Edition](https://about.gitlab.com/gitlab-ee/).
+
+Often multiple people likely work on the same issue together,
+which can especially be difficult to track in large teams
+where there is shared ownership of an issue.
+
+In GitLab Enterprise Edition, you can also select multiple assignees
+to an issue.
+
+> **Note:**
+Multiple Assignees was [introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/1904)
+in [GitLab Enterprise Edition 9.2](https://about.gitlab.com/2017/05/22/gitlab-9-2-released/#multiple-assignees-for-issues).
+
+#### 4. Milestone
+
+- Select a [milestone](../milestones/index.md) to attribute that issue to.
+
+#### 5. Time Tracking (EES/EEP)
+
+This feature is available only in [GitLab Enterprise Edition](https://about.gitlab.com/gitlab-ee/).
+
+- Estimate time: add an estimate time in which the issue will be implemented
+- Spend: add the time spent on the implementation of that issue
+
+> **Note:**
+both estimate and spend times are set via [GitLab Slash Commands](../slash_commands.md).
+
+Learn more on the [Time Tracking documentation](https://docs.gitlab.com/ee/workflow/time_tracking.html).
+
+#### 6. Due date
+
+When you work on a tight schedule, and it's important to
+have a way to setup a deadline for implementations and for solving
+problems. This can be facilitated by the [due date](due_dates.md)). Due dates
+can be changed as many times as needed.
+
+#### 7. Labels
+
+Categorize issues by giving them [labels](../labels.md). They help to
+organize team's workflows, once they enable you to work with the
+[GitLab Issue Board](index.md#gitlab-issue-board).
+
+Group Labels, which allow you to use the same labels per
+group of projects, can be also given to issues. They work exactly the same,
+but they are immediately available to all projects in the group.
+
+> **Tip:**
+if the label doesn't exist yet, when you click **Edit**, it opens a dropdown menu from which you can select **Create new label**.
+
+#### 8. Weight (EES/EEP)
+
+Issue Weights are only available in [GitLab Enterprise Edition](https://about.gitlab.com/gitlab-ee/).
+
+- Attribute a weight (in a 0 to 9 range) to that issue. Easy to complete
+should weight 1 and very hard to complete should weight 9.
+
+Learn more on the [Issue Weight documentation](https://docs.gitlab.com/ee/workflow/issue_weight.html).
+
+#### 9. Participants
+
+- People involved in that issue (mentioned in the description or in the [discussion](../../discussions/index.md)).
+
+#### 10. Notifications
+
+- Subscribe: if you are not a participant of the discussion on that issue, but
+want to receive notifications on each new input, subscribe to it.
+- Unsubscribe: if you are receiving notifications on that issue but no
+longer want to receive them, unsubscribe to it.
+
+Read more on the [notifications documentation](../../../workflow/notifications.md#issue-merge-request-events).
+
+#### 11. Reference
+
+- A quick "copy to clipboard" button to that issue's reference, `foo/bar#xxx`, where `foo` is the `username` or `groupname`, `bar`
+is the `project-name`, and `xxx` is the issue number.
+
+#### 12. Title and description
+
+- Title: a plain text title describing the issue's subject.
+- Description: a text field which fully supports [GitLab Flavored Markdown](../../markdown.md#gitlab-flavored-markdown-gfm).
+
+#### 13. @mentions
+
+- Mentions: you can either `@mention` a user or a group present in your
+GitLab instance and they will be notified via todos and email, unless that
+person has disabled all notifications in their profile settings.
+
+To change your [notification settings](../../../workflow/notifications.md) navigate to
+**Profile Settings** > **Notifications** > **Global notification level**
+and choose your preferences from the dropdown menu.
+
+> **Tip:**
+Avoid mentioning `@all` in issues and merge requests,
+as it sends an email notification
+to all the members of that project's group, which can be
+interpreted as spam.
+
+#### 14. Related Merge Requests
+
+- Any merge requests mentioned in that issue's description
+or in the issue thread.
+
+#### 15. Award emoji
+
+- Award an emoji to that issue. 
+
+> **Tip:**
+Posting "+1" as comments in threads spam all
+participants of that issue. Awarding an emoji is a way to let them
+know you like it without spamming them.
+
+#### 16. Thread
+
+- Comments: collaborate to that issue by posting comments in its thread.
+These text fields also fully support
+[GitLab Flavored Markdown](../../markdown.md#gitlab-flavored-markdown-gfm).
+
+#### 17. Comment, start a discusion, or comment and close
+
+Once you wrote your comment, you can either:
+
+- Click "Comment" and your comment will be published.
+- Click "Start discussion": start a thread within that issue's thread to discuss specific points.
+- Click "Comment and close issue": post your comment and close that issue in one click.
+
+#### 18. New Merge Request
+
+- Create a new merge request (with a new source branch named after the issue) in one action.
+The merge request will automatically close that issue as soon as merged.
+- Optionally, you can just create a [new branch](../repository/web_editor.md#create-a-new-branch-from-an-issue)
+named after that issue.

+# Pipeline Schedules
+
+> **Notes**:
+- This feature was introduced in 9.1 as [Trigger Schedule][ce-10533].
+- In 9.2, the feature was [renamed to Pipeline Schedule][ce-10853].
+- Cron notation is parsed by [Rufus-Scheduler](https://github.com/jmettraux/rufus-scheduler).
+
+Pipeline schedules can be used to run pipelines only once, or for example every
+month on the 22nd for a certain branch.
+
+## Using Pipeline schedules
+
+In order to schedule a pipeline:
+
+1. Navigate to your project's **Pipelines ➔ Schedules** and click the
+   **New Schedule** button.
+1. Fill in the form
+1. Hit **Save pipeline schedule** for the changes to take effect.
+
+![New Schedule Form](img/pipeline_schedules_new_form.png)
+
+>**Attention:**
+The pipelines won't be executed precisely, because schedules are handled by
+Sidekiq, which runs according to its interval.
+See [advanced admin configuration](#advanced-admin-configuration) for more
+information.
+
+In the **Schedules** index page you can see a list of the pipelines that are
+scheduled to run. The next run is automatically calculated by the server GitLab
+is installed on.
+
+![Schedules list](img/pipeline_schedules_list.png)
+
+## Taking ownership
+
+Pipelines are executed as a user, who owns a schedule. This influences what
+projects and other resources the pipeline has access to. If a user does not own
+a pipeline, you can take ownership by clicking the **Take ownership** button.
+The next time a pipeline is scheduled, your credentials will be used.
+
+![Schedules list](img/pipeline_schedules_ownership.png)
+
+>**Note:**
+When the owner of the schedule doesn't have the ability to create pipelines
+anymore, due to e.g., being blocked or removed from the project, the schedule
+is deactivated. Another user can take ownership and activate it, so the
+schedule can be run again.
+
+## Advanced admin configuration
+
+The pipelines won't be executed precisely, because schedules are handled by
+Sidekiq, which runs according to its interval. For example, if you set a
+schedule to create a pipeline every minute (`* * * * *`) and the Sidekiq worker
+runs on 00:00 and 12:00 every day (`0 */12 * * *`), only 2 pipelines will be
+created per day. To change the Sidekiq worker's frequency, you have to edit the
+`pipeline_schedule_worker_cron` value in your `gitlab.rb` and restart GitLab.
+For GitLab.com, you can check the [dedicated settings page][settings]. If you
+don't have admin access to the server, ask your administrator.

-// TaskList Behavior
-//
-/*= provides tasklist:enabled */
-/*= provides tasklist:disabled */
-/*= provides tasklist:change */
-/*= provides tasklist:changed */
-//
-//
-// Enables Task List update behavior.
-//
-// ### Example Markup
-//
-//   <div class="js-task-list-container">
-//     <ul class="task-list">
-//       <li class="task-list-item">
-//         <input type="checkbox" class="js-task-list-item-checkbox" disabled />
-//         text
-//       </li>
-//     </ul>
-//     <form>
-//       <textarea class="js-task-list-field">- [ ] text</textarea>
-//     </form>
-//   </div>
-//
-// ### Specification
-//
-// TaskLists MUST be contained in a `(div).js-task-list-container`.
-//
-// TaskList Items SHOULD be an a list (`UL`/`OL`) element.
-//
-// Task list items MUST match `(input).task-list-item-checkbox` and MUST be
-// `disabled` by default.
-//
-// TaskLists MUST have a `(textarea).js-task-list-field` form element whose
-// `value` attribute is the source (Markdown) to be udpated. The source MUST
-// follow the syntax guidelines.
-//
-// TaskList updates trigger `tasklist:change` events. If the change is
-// successful, `tasklist:changed` is fired. The change can be canceled.
-//
-// jQuery is required.
-//
-// ### Methods
-//
-// `.taskList('enable')` or `.taskList()`
-//
-// Enables TaskList updates for the container.
-//
-// `.taskList('disable')`
-//
-// Disables TaskList updates for the container.
-//
-//# ### Events
-//
-// `tasklist:enabled`
-//
-// Fired when the TaskList is enabled.
-//
-// * **Synchronicity** Sync
-// * **Bubbles** Yes
-// * **Cancelable** No
-// * **Target** `.js-task-list-container`
-//
-// `tasklist:disabled`
-//
-// Fired when the TaskList is disabled.
-//
-// * **Synchronicity** Sync
-// * **Bubbles** Yes
-// * **Cancelable** No
-// * **Target** `.js-task-list-container`
-//
-// `tasklist:change`
-//
-// Fired before the TaskList item change takes affect.
-//
-// * **Synchronicity** Sync
-// * **Bubbles** Yes
-// * **Cancelable** Yes
-// * **Target** `.js-task-list-field`
-//
-// `tasklist:changed`
-//
-// Fired once the TaskList item change has taken affect.
-//
-// * **Synchronicity** Sync
-// * **Bubbles** Yes
-// * **Cancelable** No
-// * **Target** `.js-task-list-field`
-//
-// ### NOTE
-//
-// Task list checkboxes are rendered as disabled by default because rendered
-// user content is cached without regard for the viewer.
