docker-git-sync

A docker image allowing you to sync a folder with a git repository.

To use it, you must pass the following environment variables:

• GIT_REPO_URL: URL of the Git repository to sync to, for example ssh://git@example.com/foo/bar.git.
• GIT_REPO_BRANCH: Branch of the Git repository to sync to, for example production. Defaults to master.
• GIT_USER_EMAIL: E-Mail address of author to show in commits
• GIT_USER_NAME: Name of author to show in commits

Optionally, you can set

• CRON_TIME: The execution time of the sync cronjob. For the syntax check CronHowto. Default is every minute (*/1 * * * *).

Furthermore you need to setup the following two volumes:

• /root/.ssh: This volume should contain a valid ssh key (id_rsa and id_rsa.pub) with write access to the specified git repository. Also it should contain a valid known_hosts file.
• /sync-dir: The contents of this volume will be synced to the speciefied git repository. If this directory is not empty (but does not contain a git repository) the sync will be aborted. In this case you need to pass the flag --overwrite-local to the container or set the environment variable OVERWRITE_LOCAL to true.

After proper setup this image will execute a cron job every minute and sync the contents of the volume /sync-dir to the specified git repository.

Of course you can mount the volumes to some directories of the host.
