-# Koding & GitLab
-
-> **Notes:**
-> - **As of GitLab 10.0, the Koding integration is deprecated and will be removed
->   in a future version. The option to configure it is removed from GitLab's admin
->   area.**
-> - [Introduced][ce-5909] in GitLab 8.11.
-
-This document will guide you through installing and configuring Koding with
-GitLab.
-
-First of all, to be able to use Koding and GitLab together you will need public
-access to your server. This allows you to use single sign-on from GitLab to
-Koding and using vms from cloud providers like AWS. Koding has a registry for
-VMs, called Kontrol and it runs on the same server as Koding itself, VMs from
-cloud providers register themselves to Kontrol via the agent that we put into
-provisioned VMs. This agent is called Klient and it provides Koding to access
-and manage the target machine.
-
-Kontrol and Klient are based on another technology called
-[Kite](https://github.com/koding/kite), that we have written at Koding. Which is a
-microservice framework that allows you to develop microservices easily.
-
-## Requirements
-
-### Hardware
-
-Minimum requirements are;
-
-  - 2 cores CPU
-  - 3G RAM
-  - 10G Storage
-
-If you plan to use AWS to install Koding it is recommended that you use at
-least a `c3.xlarge` instance.
-
-### Software
-
-  - [Git](https://git-scm.com)
-  - [Docker](https://www.docker.com)
-  - [docker-compose](https://www.docker.com/products/docker-compose)
-
-Koding can run on most of the UNIX based operating systems, since it's shipped
-as containerized with Docker support, it can work on any operating system that
-supports Docker.
-
-Required services are:
-
-- **PostgreSQL** - Kontrol and Service DB provider
-- **MongoDB**    - Main DB provider the application
-- **Redis**      - In memory DB used by both application and services
-- **RabbitMQ**   - Message Queue for both application and services
-
-which are also provided as a Docker container by Koding.
-
-
-## Getting Started with Development Versions
-
-
-### Koding
-
-You can run `docker-compose` environment for developing koding by
-executing commands in the following snippet.
-
-```bash
-git clone https://github.com/koding/koding.git
-cd koding
-docker-compose -f docker-compose-init.yml run init
-docker-compose up
-```
-
-This should start koding on `localhost:8090`.
-
-By default there is no team exists in Koding DB. You'll need to create a team
-called `gitlab` which is the default team name for GitLab integration in the
-configuration. To make things in order it's recommended to create the `gitlab`
-team first thing after setting up Koding.
-
-
-### GitLab
-
-To install GitLab to your environment for development purposes it's recommended
-to use GitLab Development Kit which you can get it from
-[here](https://gitlab.com/gitlab-org/gitlab-development-kit).
-
-After all those steps, gitlab should be running on `localhost:3000`
-
-
-## Integration
-
-Integration includes following components;
-
-  - Single Sign On with OAuth from GitLab to Koding
-  - System Hook integration for handling GitLab events on Koding
-    (`project_created`, `user_joined` etc.)
-  - Service endpoints for importing/executing stacks from GitLab to Koding
-    (`Run/Try on IDE (Koding)` buttons on GitLab Projects, Issues, MRs)
-
-As it's pointed out before, you will need public access to this machine that
-you've installed Koding and GitLab on. Better to use a domain but a static IP
-is also fine.
-
-For IP based installation you can use [nip.io](https://nip.io) service which is
-free and provides DNS resolution to IP based requests like following;
-
-  - 127.0.0.1.nip.io              -> resolves to 127.0.0.1
-  - foo.bar.baz.127.0.0.1.nip.io  -> resolves to 127.0.0.1
-  - and so on...
-
-As Koding needs subdomains for team names; `foo.127.0.0.1.nip.io` requests for
-a running koding instance on `127.0.0.1` server will be handled as `foo` team
-requests.
-
-
-### GitLab Side
-
-You need to enable Koding integration from Settings under Admin Area. To do
-that login with an Admin account and do followings;
-
-- open [http://127.0.0.1:3000/admin/application_settings](http://127.0.0.1:3000/admin/application_settings)
-- scroll to bottom of the page until Koding section
-- check `Enable Koding` checkbox
-- provide GitLab team page for running Koding instance as `Koding URL`*
-  * For `Koding URL` you need to provide the gitlab integration enabled team on
-your Koding installation. Team called `gitlab` has integration on Koding out
-of the box, so if you didn't change anything your team on Koding should be
-`gitlab`.
-
-So, if your Koding is running on `http://1.2.3.4.nip.io:8090` your URL needs
-to be `http://gitlab.1.2.3.4.nip.io:8090`. You need to provide the same host
-with your Koding installation here.
-
-
-#### Registering Koding for OAuth integration
-
-We need `Application ID` and `Secret` to enable login to Koding via GitLab
-feature and to do that you need to register running Koding as a new application
-to your running GitLab application. Follow
-[these](http://docs.gitlab.com/ce/integration/oauth_provider.html) steps to
-enable this integration.
-
-Redirect URI should be `http://gitlab.127.0.0.1:8090/-/oauth/gitlab/callback`
-which again you need to _replace `127.0.0.1` with your instance public IP._
-
-Take a copy of `Application ID` and `Secret` that is generated by the GitLab
-application, we will need those on _Koding Part_ of this guide.
-
-
-#### Registering system hooks to Koding (optional)
-
-Koding can take actions based on the events generated by GitLab application.
-This feature is still in progress and only following events are processed by
-Koding at the moment;
-
-  - user_create
-  - user_destroy
-
-All system events are handled but not implemented on Koding side.
-
-To enable this feature you need to provide a `URL` and a `Secret Token` to your
-GitLab application. Open your admin area on your GitLab app from
-[http://127.0.0.1:3000/admin/hooks](http://127.0.0.1:3000/admin/hooks)
-and provide `URL` as `http://gitlab.127.0.0.1:8090/-/api/gitlab` which is the
-endpoint to handle GitLab events on Koding side. Provide a `Secret Token` and
-keep a copy of it, we will need it on _Koding Part_ of this guide.
-
-_(replace `127.0.0.1` with your instance public IP)_
-
-
-### Koding Part
-
-If you followed the steps in GitLab part we should have followings to enable
-Koding part integrations;
-
-  - `Application ID` and `Secret` for OAuth integration
-  - `Secret Token` for system hook integration
-  - Public address of running GitLab instance
-
-
-#### Start Koding with GitLab URL
-
-Now we need to configure Koding with all this information to get things ready.
-If it's already running please stop koding first.
-
-##### From command-line
-
-Replace followings with the ones you got from GitLab part of this guide;
-
-```bash
-cd koding
-docker-compose run                              \
-  --service-ports backend                       \
-  /opt/koding/scripts/bootstrap-container build \
-  --host=**YOUR_IP**.nip.io                     \
-  --gitlabHost=**GITLAB_IP**                    \
-  --gitlabPort=**GITLAB_PORT**                  \
-  --gitlabToken=**SECRET_TOKEN**                \
-  --gitlabAppId=**APPLICATION_ID**              \
-  --gitlabAppSecret=**SECRET**
-```
-
-##### By updating configuration
-
-Alternatively you can update `gitlab` section on
-`config/credentials.default.coffee` like following;
-
-```
-gitlab =
-  host: '**GITLAB_IP**'
-  port: '**GITLAB_PORT**'
-  applicationId: '**APPLICATION_ID**'
-  applicationSecret: '**SECRET**'
-  team: 'gitlab'
-  redirectUri: ''
-  systemHookToken: '**SECRET_TOKEN**'
-  hooksEnabled: yes
-```
-
-and start by only providing the `host`;
-
-```bash
-cd koding
-docker-compose run                              \
-  --service-ports backend                       \
-  /opt/koding/scripts/bootstrap-container build \
-  --host=**YOUR_IP**.nip.io                     \
-```
-
-#### Enable Single Sign On
-
-Once you restarted your Koding and logged in with your username and password
-you need to activate oauth authentication for your user. To do that
-
- - Navigate to Dashboard on Koding from;
-   `http://gitlab.**YOUR_IP**.nip.io:8090/Home/my-account`
- - Scroll down to Integrations section
- - Click on toggle to turn On integration in GitLab integration section
-
-This will redirect you to your GitLab instance and will ask your permission (
-if you are not logged in to GitLab at this point you will be redirected after
-login) once you accept you will be redirected to your Koding instance.
-
-From now on you can login by using `SIGN IN WITH GITLAB` button on your Login
-screen in your Koding instance.
