GitLab on Docker

Install GitLab running on Docker Here is the official document. I followed it. Caution: I’m using my GitLab on VM, not Docker image. Because the official image doesn’t contain e-mail client, and it is a little bit hard to understand. For me, deploying it on premise or VM is easy. Install docker apt install -y Set path export GITLAB_HOME=/srv/gitlab Configurations and repositories would be stored in this path. Run a container sudo docker run --detach \ --hostname {{ your_hostname }} \ --publish 443:443 --publish 80:80 --publish 2222:22 \ --name gitlab \ --restart always \ --volume $GITLAB_HOME/config:/etc/gitlab \ --volume $GITLAB_HOME/logs:/var/log/gitlab \ --volume $GITLAB_HOME/data:/var/opt/gitlab \ gitlab/gitlab-ce:latest I changed git port to 2222 because the server should be access by ssh.

Docker network

Docker - intro

Install macOS Environment: macOS 10.15.3 (Intel chip), Mar. 2020. Installing Docker in macOS, the official document seems to recommend installing Docker Desktop with the installer. I don’t need desktop function so far, but this is not so critical when I learn Docker. And it is the easiest way to install Docker CLI in macOS. If you don’t have DockerID, please make it first.
