Dokku GitLab

Instructions for installing GitLab as a Dokku application, using the official GitLab CE Docker image.

Setup application

Create dokku application:

dokku apps:create gitlab

Create storage folders:

mkdir -p /home/storage/gitlab/data
mkdir -p /home/storage/gitlab/logs
mkdir -p /home/storage/gitlab/config

Mount storage folders:

dokku storage:mount gitlab /home/storage/gitlab/config:/etc/gitlab
dokku storage:mount gitlab /home/storage/gitlab/logs:/var/log/gitlab
dokku storage:mount gitlab /home/storage/gitlab/data:/var/opt/gitlab

Set proxy ports map and docker options:

dokku proxy:ports-set gitlab http:80:80
dokku docker-options:add gitlab deploy '-p 2222:22'

Edit configuration

Create gitlab.rb in /home/storage/gitlab/config and add the following settings:

# GitLab URL
##! URL on which GitLab will be reachable.
##! For more details on configuring external_url see:
##! https://docs.gitlab.com/omnibus/settings/configuration.html#configuring-the-external-url-for-gitlab
external_url 'https://gitlab.example.com'
##! **Override only if you use a reverse proxy**
##! Docs: https://docs.gitlab.com/omnibus/settings/nginx.html#setting-the-nginx-listen-port
nginx['listen_port'] = 80
##! **Override only if your reverse proxy internally communicates over HTTP**
##! Docs: https://docs.gitlab.com/omnibus/settings/nginx.html#supporting-proxied-ssl
nginx['listen_https'] = false

Deploy application

Clone this repository and push it to your dokku server:

git clone https://github.com/hardpixel/dokku-gitlab.git
cd dokku-gitlab
git remote add dokku dokku@example.com:gitlab
git push dokku master

Enable SSL

Generate LetsEncrypt certificates:

dokku letsencrypt gitlab

Configure GIT

Update ssh config, located at ~/.ssh/config, on your local machine:

Host gitlab.example.com
    Port 2222

Reconfigure GitLab

Connect to the gitlab app container:

dokku enter gitlab
gitlab-ctl reconfigure

Or run the command from outside the app container:

dokku run gitlab gitlab-ctl reconfigure

Update GitLab

Before updating you have to stop the running container or the update will fail.

dokku ps:stop gitlab
docker pull gitlab/gitlab-ce
dokku ps:rebuild gitlab
