How to Setup Jenkins & GitLab using Docker Containers

This article represents code sample on how to setup Jenkins & GitLab using Docker containers. Please feel free to comment/suggest if I missed to mention one or more important points. Also, sorry for the typos.

Create a docker compose file such as docker-compose.yml with the code given below. Executing command such as “docker-compose up” would lead to creation of two containers, one of which hosts the Jenkins and another one hosts GitLab. The Jenkins can be accessed with URL such as http://localhost:28080. The GitLab can be accessed using URL such as http://localhost. In case of running this docker-compose file on Linux/Ubuntu, change the volume under jenkins from “- /usr/local/bin/docker:/usr/bin/docker” to “- /usr/bin/docker:/usr/bin/docker”.

version: '2'

networks:
  prodnetwork:
    driver: bridge

services:
 jenkins:
  image: jenkins
  ports:
    - "28080:8080"
  networks:
    - prodnetwork
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock
    - /usr/local/bin/docker:/usr/bin/docker
    - /opt/jenkins/:/var/lib/jenkins/
  depends_on:
    - gitlab

 gitlab:
  image: gitlab/gitlab-ce
  restart: always
  networks:
    - prodnetwork
  environment:
    GITLAB_OMNIBUS_CONFIG: |
      # external_url 'https://gitlab.example.com'
      # Add any other gitlab.rb configuration here, each on its own line
  ports:
    - "80:80"
    - "443:443"
    - "2222:22"
  volumes:
    - /opt/gitlab/config:/etc/gitlab
    - /opt/gitlab/logs:/var/log/gitlab
    - /opt/gitlab/data:/var/opt/gitlab
