+## Using self-signed certificates with Container Registry
+
+If you're using a self-signed certificate with your Container Registry, you
+might encounter issues during the CI jobs like the following:

+```
+Error response from daemon: Get registry.example.com/v1/users/: x509: certificate signed by unknown authority
+```
 
-**GitLab 8.8 ([source docs][8-8-docs])**
+The Docker daemon running the command expects a cert signed by a recognized CA,
+thus the error above.
 
-- GitLab Container Registry feature was introduced.
+While GitLab doesn't support using self-signed certificates with Container
+Registry out of the box, it is possible to make it work if you follow

+# Installing Git
+
+> **Article [Type](../../development/writing_documentation.html#types-of-technical-articles):** user guide ||
+> **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
+

 ## Define an image from a private Docker registry
 
-Starting with GitLab Runner 0.6.0, you are able to define images located to
-private registries that could also require authentication.
-
-All you have to do is be explicit on the image definition in `.gitlab-ci.yml`.
-
-```yaml
-image: my.registry.tld:5000/namepace/image:tag
-```
-
-In the example above, GitLab Runner will look at `my.registry.tld:5000` for the
-image `namespace/image:tag`.
-
-If the repository is private you need to authenticate your GitLab Runner in the
-registry. Learn how to do that on
-[GitLab Runner's documentation][runner-priv-reg].
+> **Notes:**
+- This feature requires GitLab Runner **1.8** or higher
+- For GitLab Runner versions **>= 0.6, <1.8** there was a partial
+  support for using private registries, which required manual configuration
+  of credentials on runner's host. We recommend to upgrade your Runner to
+  at least version **1.8** if you want to use private registries.
+- If the repository is private you need to authenticate your GitLab Runner in the
+  registry. Learn more about how [GitLab Runner works in this case][runner-priv-reg].
+
+As an example, let's assume that you want to use the `registry.example.com/private/image:latest`
+image which is private and requires you to login into a private container registry.
+To configure access for `registry.example.com`, follow these steps:
+
+1. Do a `docker login` on your computer:
+
+     ```bash
+     docker login registry.example.com --username my_username --password my_password
+     ```
+
+1. Copy the content of `~/.docker/config.json`
+1. Create a [secret variable] `DOCKER_AUTH_CONFIG` with the content of the
+   Docker configuration file as the value:
+
+     ```json
+     {
+         "auths": {
+             "registry.example.com": {
+                 "auth": "bXlfdXNlcm5hbWU6bXlfcGFzc3dvcmQ="
+             }
+         }
+     }
+     ```
+
+1. Do a `docker logout` on your computer if you don't need access to the
+   registry from it:
+
+     ```bash
+     docker logout registry.example.com
+     ```
+
+1. You can now use any private image from `registry.example.com` defined in
+   `image` and/or `services` in your [`.gitlab-ci.yml` file][yaml-priv-reg]:
+
+      ```yaml
+      image: my.registry.tld:5000/namespace/image:tag
+      ```
+
+      In the example above, GitLab Runner will look at `my.registry.tld:5000` for the
+      image `namespace/image:tag`.
+
+You can add configuration for as many registries as you want, adding more
+registries to the `"auths"` hash as described above.

+# 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][dind].
+
+Once you set up the Runner, add a new job to `.gitlab-ci.yml`, called `codeclimate`:
+
+```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.
+
+For GitLab [Enterprise Edition Starter][ee] users, this information can be automatically
+extracted and shown right in the merge request widget. [Learn more on code quality

 [`Notification`](https://developer.mozilla.org/en-US/docs/Web/API/notification),
 which will have to be stubbed.
 
-### 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.

+# Polymorphic Associations
+
+**Summary:** always use separate tables instead of polymorphic associations.
+
+Rails makes it possible to define so called "polymorphic associations". This
+usually works by adding two columns to a table: a target type column, and a
+target id. For example, at the time of writing we have such a setup for
+`members` with the following columns:
+
+* `source_type`: a string defining the model to use, can be either `Project` or
+  `Namespace`.
+* `source_id`: the ID of the row to retrieve based on `source_type`. For
+  example, when `source_type` is `Project` then `source_id` will contain a
+  project ID.
+
+While such a setup may appear to be useful, it comes with many drawbacks; enough
+that you should avoid this at all costs.
+
+## Space Wasted
+
+Because this setup relies on string values to determine the model to use it will
+end up wasting a lot of space. For example, for `Project` and `Namespace` the
+maximum size is 9 bytes, plus 1 extra byte for every string when using
+PostgreSQL. While this may only be 10 bytes per row, given enough tables and
+rows using such a setup we can end up wasting quite a bit of disk space and
+memory (for any indexes).
+
+## Indexes
+
+Because our associations are broken up into two columns this may result in
+requiring composite indexes for queries to be performed efficiently. While
+composite indexes are not wrong at all, they can be tricky to set up as the
+ordering of columns in these indexes is important to ensure optimal performance.
+
+## Consistency
+
+One really big problem with polymorphic associations is being unable to enforce
+data consistency on the database level using foreign keys. For consistency to be
+enforced on the database level one would have to write their own foreign key
+logic to support polymorphic associations.
+
+Enforcing consistency on the database level is absolutely crucial for
+maintaining a healthy environment, and thus is another reason to avoid
+polymorphic associations.
+
+## Query Overhead
+
+When using polymorphic associations you always need to filter using both
+columns. For example, you may end up writing a query like this:
+
+```sql
+SELECT *
+FROM members
+WHERE source_type = 'Project'
+AND source_id = 13083;
+```
+
+Here PostgreSQL can perform the query quite efficiently if both columns are
+indexed, but as the query gets more complex it may not be able to use these
+indexes efficiently.
+
+## Mixed Responsibilities
+
+Similar to functions and classes a table should have a single responsibility:
+storing data with a certain set of pre-defined columns. When using polymorphic
+associations you are instead storing different types of data (possibly with
+different columns set) in the same table.
+
+## The Solution
+
+Fortunately there is a very simple solution to these problems: simply use a
+separate table for every type you would otherwise store in the same table. Using
+a separate table allows you to use everything a database may provide to ensure
+consistency and query data efficiently, without any additional application logic
+being necessary.
+
+Let's say you have a `members` table storing both approved and pending members,
+for both projects and groups, and the pending state is determined by the column
+`requested_at` being set or not. Schema wise such a setup can lead to various
+columns only being set for certain rows, wasting space. It's also possible that
+certain indexes will only be set for certain rows, again wasting space. Finally,
+querying such a table requires less than ideal queries. For example:
+
+```sql
+SELECT *
+FROM members
+WHERE requested_at IS NULL
+AND source_type = 'GroupMember'
+AND source_id = 4
+```
+
+Instead such a table should be broken up into separate tables. For example, you
+may end up with 4 tables in this case:
+
+* project_members
+* group_members
+* pending_project_members
+* pending_group_members
+
+This makes querying data trivial. For example, to get the members of a group
+you'd run:
+
+```sql
+SELECT *
+FROM group_members
+WHERE group_id = 4
+```
+
+To get all the pending members of a group in turn you'd run:
+
+```sql
+SELECT *
+FROM pending_group_members
+WHERE group_id = 4
+```
+
+If you want to get both you can use a UNION, though you need to be explicit
+about what columns you want to SELECT as otherwise the result set will use the
+columns of the first query. For example:
+
+```sql
+SELECT id, 'Group' AS target_type, group_id AS target_id
+FROM group_members
+
+UNION ALL
+
+SELECT id, 'Project' AS target_type, project_id AS target_id
+FROM project_members
+```
+
+The above example is perhaps a bit silly, but it shows that there's nothing
+stopping you from merging the data together and presenting it on the same page.
+Selecting columns explicitly can also speed up queries as the database has to do
+less work to get the data (compared to selecting all columns, even ones you're
+not using).
+
+Our schema also becomes easier. No longer do we need to both store and index the
+`source_type` column, we can define foreign keys easily, and we don't need to
+filter rows using the `IS NULL` condition.
+
+To summarize: using separate tables allows us to use foreign keys effectively,
+create indexes only where necessary, conserve space, query data more
+efficiently, and scale these tables more easily (e.g. by storing them on
+separate disks). A nice side effect of this is that code can also become easier
+as you won't end up with a single model having to handle different kinds of
+data.

+# 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.

+# Single Table Inheritance
+
+**Summary:** don't use Single Table Inheritance (STI), use separate tables
+instead.
+
+Rails makes it possible to have multiple models stored in the same table and map
+these rows to the correct models using a `type` column. This can be used to for
+example store two different types of SSH keys in the same table.
+
+While tempting to use one should avoid this at all costs for the same reasons as
+outlined in the document ["Polymorphic Associations"](polymorphic_associations.md).

+

+with `type` set to either `Key` or `DeployKey` you'd have two separate tables:

+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). 
+>**Note:**

+
+#### 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)

+## Rotate Two-factor Authentication (2FA) encryption key
+
+GitLab stores the secret data enabling 2FA to work in an encrypted database
+column. The encryption key for this data is known as `otp_key_base`, and is
+stored in `config/secrets.yml`.
+
+
+If that file is leaked, but the individual 2FA secrets have not, it's possible
+to re-encrypt those secrets with a new encryption key. This allows you to change
+the leaked key without forcing all users to change their 2FA details.
+
+First, look up the old key. This is in the `config/secrets.yml` file, but
+**make sure you're working with the production section**. The line you're
+interested in will look like this:
+
+```yaml
+production:
+  otp_key_base: ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
+```
+
+Next, generate a new secret:
+
+```
+# omnibus-gitlab
+sudo gitlab-rake secret
+
+# installation from source
+bundle exec rake secret RAILS_ENV=production
+```
+
+Now you need to stop the GitLab server, back up the existing secrets file and
+update the database:
+
+```
+# omnibus-gitlab
+sudo gitlab-ctl stop
+sudo cp config/secrets.yml config/secrets.yml.bak
+sudo gitlab-rake gitlab:two_factor:rotate_key:apply filename=backup.csv old_key=<old key> new_key=<new key>
+
+# installation from source
+sudo /etc/init.d/gitlab stop
+cp config/secrets.yml config/secrets.yml.bak
+bundle exec rake gitlab:two_factor:rotate_key:apply filename=backup.csv old_key=<old key> new_key=<new key> RAILS_ENV=production
+```
+
+The `<old key>` value can be read from `config/secrets.yml`; `<new key>` was
+generated earlier. The **encrypted** values for the user 2FA secrets will be
+written to the specified `filename` - you can use this to rollback in case of
+error.
+
+Finally, change `config/secrets.yml` to set `otp_key_base` to `<new key>` and
+restart. Again, make sure you're operating in the **production** section.
+
+```
+# omnibus-gitlab
+sudo gitlab-ctl start
+
+# installation from source
+sudo /etc/init.d/gitlab start
+```
+
+If there are any problems (perhaps using the wrong value for `old_key`), you can
+restore your backup of `config/secrets.yml` and rollback the changes:
+
+```
+# omnibus-gitlab
+sudo gitlab-ctl stop
+sudo gitlab-rake gitlab:two_factor:rotate_key:rollback filename=backup.csv
+sudo cp config/secrets.yml.bak config/secrets.yml
+sudo gitlab-ctl start
+
+# installation from source
+sudo /etc/init.d/gitlab start
+bundle exec rake gitlab:two_factor:rotate_key:rollback filename=backup.csv RAILS_ENV=production

+
+### 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. Update Go
+
+NOTE: GitLab 9.3 and higher only supports Go 1.8.3 and dropped support for Go 1.5.x through 1.7.x. Be
+sure to upgrade your installation if necessary
+
+You can check which version you are running with `go version`.
+
+Download and install Go:
+
+```bash
+# Remove former Go installation folder
+sudo rm -rf /usr/local/go
+
+curl --remote-name --progress https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz
+echo '1862f4c3d3907e59b04a757cfda0ea7aa9ef39274af99a784f5be843c80c6772  go1.8.3.linux-amd64.tar.gz' | shasum -a256 -c - && \
+  sudo tar -C /usr/local -xzf go1.8.3.linux-amd64.tar.gz
+sudo ln -sf /usr/local/go/bin/{go,godoc,gofmt} /usr/local/bin/
+rm go1.8.3.linux-amd64.tar.gz
+```
+
+### 6. 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
+```
+
+### 5. Update gitlab-shell
+
+```bash
+cd /home/git/gitlab-shell
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_SHELL_VERSION)
+sudo -u git -H bin/compile
+```
+
+### 6. Update gitlab-workhorse
+
+Install and compile gitlab-workhorse. This requires
+[Go 1.5](https://golang.org/dl) which should already be on your system from
+GitLab 8.1. GitLab-Workhorse uses [GNU Make](https://www.gnu.org/software/make/).
+If you are not using Linux you may have to run `gmake` instead of
+`make` below.
+
+```bash
+cd /home/git/gitlab-workhorse
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_WORKHORSE_VERSION)
+sudo -u git -H make
+```
+
+### 7. 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
+```
+
+### 10. 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].
+
+[Apache templates]: https://gitlab.com/gitlab-org/gitlab-recipes/tree/master/web-server/apache
+[/etc/default/gitlab]: https://gitlab.com/gitlab-org/gitlab-ce/blob/9-3-stable/lib/support/init.d/gitlab.default.example#L38
+
+#### 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
+ActionMailer::Base.delivery_method = :smtp
+```
+
+See [smtp_settings.rb.sample] as an example.
+
+[smtp_settings.rb.sample]: https://gitlab.com/gitlab-org/gitlab-ce/blob/9-2-stable/config/initializers/smtp_settings.rb.sample#L13
+
+#### Init script
+
+There might be new configuration options available for [`gitlab.default.example`][gl-example]. View them with the command below and apply them manually to your current `/etc/default/gitlab`:
+
+```sh
+cd /home/git/gitlab
+
+git diff origin/9-2-stable:lib/support/init.d/gitlab.default.example origin/9-3-stable:lib/support/init.d/gitlab.default.example
+```
+
+Ensure you're still up-to-date with the latest init script changes:
+
+```bash
+cd /home/git/gitlab
+
+sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
+```
+
+For Ubuntu 16.04.1 LTS:
+
+```bash
+sudo systemctl daemon-reload
+```
+
+### 11. Install libs, migrations, etc.
+
+```bash
+cd /home/git/gitlab
+
+# MySQL installations (note: the line below states '--without postgres')
+sudo -u git -H bundle install --without postgres development test --deployment
+
+# PostgreSQL installations (note: the line below states '--without mysql')
+sudo -u git -H bundle install --without mysql development test --deployment
+
+# Optional: clean up old gems
+sudo -u git -H bundle clean
+
+# Run database migrations
+sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
+
+# Update node dependencies and recompile assets
+sudo -u git -H bundle exec rake yarn:install gitlab:assets:clean gitlab:assets:compile RAILS_ENV=production NODE_ENV=production
+
+# Clean up cache
+sudo -u git -H bundle exec rake cache:clear RAILS_ENV=production
+```
+
+**MySQL installations**: Run through the `MySQL strings limits` and `Tables and data conversion to utf8mb4` [tasks](../install/database_mysql.md).
+
+### 12. Start application
+
+```bash
+sudo service gitlab start
+sudo service nginx restart
+```
+
+### 13. 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 (9.2)
+
+### 1. Revert the code to the previous version
+
+Follow the [upgrade guide from 9.1 to 9.2](9.1-to-9.2.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.

-// 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.
