A GitLab CE base image to run a GitLab CE instance

This project contains a Docker image that can be used as a base image to create a new Docker image customised for your environment.

Building the Docker image yourself and hosting it

1. Clone this repository.

2. Build the Docker image.

   docker build -t <your-docker-repo>/centos-gitlab-ce:latest .

3. Deploy the image to your repository

   docker push <your-docker-repo>/centos-gitlab-ce:latest

Running this image locally

Run the image locally by enabling the required ports and volumes as below (replace host directories with your own).

docker run -i -t -v /Users/tyrell/git/centos-gitlab-ce/host_directories/etc/gitlab:/etc/gitlab -v /Users/tyrell/git/centos-gitlab-ce/host_directories/var/opt/gitlab:/var/opt/gitlab -v /Users/tyrell/git/centos-gitlab-ce/host_directories/var/log/gitlab:/var/log/gitlab -p 127.0.0.1:80:80/tcp -p 127.0.0.1:443:443/tcp tyrell/centos-gitlab-ce:12.0.3-ce.0.el7.x86_64 /bin/bash

Once the image is running, use docker exec to enter into the image for verification.

Tyrells-MacBook-Air:~ tyrell$ docker exec -it 6ff0c9f9f6f1 /bin/bash

Running this image in Openshift

1. oc login
2. oc new-project gitlab
3. sh openshift/create-openshift-app.sh

The openshift/create-openshift-app.sh script uses the image hosted at https://hub.docker.com/r/tyrell/centos-gitlab-ce and creates the required Persistent Volume Claims in Openshift for persistent storage volume mounts.

Delete the Openshift application using;

oc delete all -l app=gitlab-ce

Initialising GitLab

Run /assets/wrapper to initialise GitLab for the first time. This script creates all the necessary dependencies and database schemas etc.

Notes

1. conf/gitlab.rb is copied into the image during build.
2. conf/sysctl.rb is a modified version to prevent all the sysctl kernel parameter modifications performed during reconfigure. It is expected that PostgreSQL will be running on its own container during a proper deployment.
