casadocker/git-server repository overview

⁠Git server on Docker

⁠Run docker git-server container

$ docker-compose up -d

⁠Add repository to git server

1. Create bare repository, either initiated as an empty repository or cloned from an existing repository.

$ git init --bare ionradan.git                        # create empty bare repository
$ git clone --bare repo_to_bare_clone ionradan.git    # create bare repository from an existing repository

1. Copy repository to git server

$ docker cp ionradan.git git-server:/opt/git/repositories    # move bare repository to git server

1. Clone repository

• ssh protocol

  $ git clone git@localhost:/opt/git/repositories/ionradan.git
  $ git clone ssh://git@localhost:2224/opt/git/repositories/ionradan.git    # non-standard ssh port
  

  Copy

• git protocol (read only)

  $ git clone git://localhost/ionradan.git
  

  Copy

1. Backup

   $ docker run --rm --volumes-from git-server -v $(pwd):/backup ubuntu tar cvf /backup/git-repositories.tar /opt/git/repositories

• When the command completes and the container stops we’ll be left with a backup of /opt/git/repositories directory (from git-server container)

⁠Add key

• Add key to files/authorized_keys and rebuild image. Compromise to achieve the immutable environment principle.

⁠Generate keys

• $ ssh-keygen -t rsa -b 4096 -C "[email protected]"
