Koding & GitLab
Introduced 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, that we have written at Koding. Which is a microservice framework that allows you to develop microservices easily.
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
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
You can run
docker-compose environment for developing koding by
executing commands in the following snippet.
git clone https://github.com/koding/koding.git cd koding docker-compose up
This should start koding on
By default there is no team exists in Koding DB. You'll need to create a team
gitlab which is the default team name for GitLab integration in the
configuration. To make things in order it's recommended to create the
team first thing after setting up Koding.
To install GitLab to your environment for development purposes it's recommended to use GitLab Development Kit which you can get it from here.
After all those steps, gitlab should be running on
Integration includes following components;
- Single Sign On with OAuth from GitLab to Koding
- System Hook integration for handling GitLab events on Koding
- 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 xip.io service which is free and provides DNS resolution to IP based requests like following;
- 127.0.0.1.xip.io -> resolves to 127.0.0.1
- foo.bar.baz.127.0.0.1.xip.io -> resolves to 127.0.0.1
- and so on...
As Koding needs subdomains for team names;
foo.127.0.0.1.xip.io requests for
a running koding instance on
127.0.0.1 server will be handled as
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
- scroll to bottom of the page until Koding section
provide GitLab team page for running Koding instance as
Koding URLyou need to provide the gitlab integration enabled team on your Koding installation. Team called
gitlabhas integration on Koding out of the box, so if you didn't change anything your team on Koding should be
So, if your Koding is running on
http://126.96.36.199.xip.io:8090 your URL needs
http://gitlab.188.8.131.52.xip.io:8090. You need to provide the same host
with your Koding installation here.
Registering Koding for OAuth integration
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 steps to
enable this integration.
Redirect URI should be
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;
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://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.
127.0.0.1 with your instance public IP)
If you followed the steps in GitLab part we should have followings to enable Koding part integrations;
Secretfor OAuth integration
Secret Tokenfor 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.
Replace followings with the ones you got from GitLab part of this guide;
cd koding docker-compose run \ --service-ports backend \ /opt/koding/scripts/bootstrap-container build \ --host=**YOUR_IP**.xip.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
cd koding docker-compose run \ --service-ports backend \ /opt/koding/scripts/bootstrap-container build \ --host=**YOUR_IP**.xip.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;
- 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.
