Host Your Own GitHub Alternative with GitLab Docker Container

What is GitLab

GitLab is an open source end-to-end software development platform with built-in version control, issue tracking, code review, CI/CD, and more. Self-host GitLab on your own servers, in a container, or on a cloud provider. -https://gitlab.com/gitlab-org/gitlab

Installing Docker

  1. Log into the Linux based device
  2. Run the following commands in the terminal

    # add docker gpg key
    curl -fsSL https://download.docker.com/linux/$(awk -F'=' '/^ID=/{ print $NF }' /etc/os-release)/gpg | sudo apt-key add -
    # add docker software repository
    sudo add-apt-repository "deb [arch=$(dpkg --print-architecture)] https://download.docker.com/linux/$(awk -F'=' '/^ID=/{ print $NF }' /etc/os-release) $(lsb_release -cs) stable"
    # install docker
    sudo apt install docker-ce docker-compose containerd.io -y
    # enable and start docker service
    sudo systemctl enable docker && sudo systemctl start docker
    # add the current user to the docker group
    sudo usermod -aG docker $USER
    # reauthenticate for the new group membership to take effect

  1. Now that Docker is installed, run the following commands to setup the GitLab Docker container and run it
    # create working directory
    sudo mkdir /home/$USER/docker/gitlab -p
    # run the GitLab docker container
    docker run --name gitlab -d --hostname DNSofHost -p 8000:80 -v /home/$USER/docker/gitlab/config:/etc/gitlab -v /home/$USER/docker/gitlab/logs:/var/log/gitlab -v /home/$USER/docker/gitlab/data:/var/opt/gitlab --restart=unless-stopped gitlab/gitlab-ce:latest
    # output root user password
    docker exec -it gitlab cat /etc/gitlab/initial_root_password
  2. Copy the password to your clipboard
  3. Open a web browser and navigate to http://DNSorIP:8000
