gitweb

Minimal git server with gitweb and rsync backup in a Docker container

Getting started

Copy the env.example file and edit the variables. This config is mounted into the container. The $REPOS variable is read during runtime. The Backup is done via git bundle files. If a bundle exists at the backup location (with a .bundle file extension) we copy it to the server and clone the repo. If not, we create a new repo. After 30 seconds (the next check loop) we create a backup of the new repo.

To preserve repos and/or the zerotier config during container restarts create a volume mapping to the /git/repos or /var/lib/zerotier-one folder.

Zerotier additionally needs the ability to create tun/tap devices which can be enabled with --cap-add=NET_ADMIN --cap-add=SYS_ADMIN --device=/dev/net/tun

cp env.example env
vi env

docker run --rm -it -v $(pwd)/env:/.env:ro -p 30080:80 -p 30022:22  kaitsh/gitweb

Clone a repo with ssh or http

git clone ssh://git@localhost:30022/git/repo1.git

git clone http://localhost:30080/repo1.git

NOTE: http is currently disabled. Please only use ssh.

Run the init script

cd repo1
./init.sh

Init Script

Every new repo contains an initial commit with a init.sh script. This script is a setup script for git config and git hooks. The script can be changed in init.template. If you want your new repositories to be empty, remove the "initial commit" command in sync.sh.

By default init.sh configures the git config user.name, git config user.email and creates a pre-commit-hook and pre-commit.d-hook directory. This directory contains all pre-commit hook scripts. The hook itself is a wrapper which calls all scripts inside the hook directory. To support other hooks, simply copy the wrapper script and create a new hook directory. By default only the no-commit.sh script is active. This script prevents a commit, if the changes contain a no-commit.

Build a custom container

You probably only need to make changes to service.sh or sync.sh. service.sh contains the config for sshd and nginx. sync.sh contains config for creating and syncing the repos.

Make your changes and run

docker build -t local/gitweb .

to create a new container.

TODOs

• HTTPS Support (must be manually enabled in service.sh)
• Better config
• Error handling
