appertly/git-sync repository overview

⁠docker-git-sync

A better Git synchronization sidecar container.

⁠Environment Variables

We use a lot of the same environment variables that the Kubernetes git-sync container does

• GIT_SYNC_REPO – The URL for the Git repository.
• GIT_SYNC_BRANCH – The branch to clone. master by default.
• GIT_SYNC_DEPTH – The history depth to pull (by default, unspecified).
• GIT_SYNC_ROOT – The directory into which the repository will be cloned (/git by default).
• GIT_SYNC_PERMISSIONS – Any cloned files will be chmoded to this
• GIT_SYNC_SSH – Whether we should use SSH (false by default).
• GIT_SYNC_WAIT – The number of seconds to wait between pulls (30 by default).
• GIT_SYNC_ONE_TIME – Whether we should clone once and never pull again.
• GIT_SYNC_USERNAME – The auth username to use.
• GIT_SYNC_PASSWORD – The auth password to use.

Plus we add a couple more.

• GIT_SYNC_CHOWN – Any cloned files will be chowned to this
• GIT_SYNC_CHGRP – Any cloned files will be chgrped to this
• GIT_SYNC_POST_PULL – This is a command that will be run after any git clone or git pull.

⁠SSH Keys

You can provide SSH keys to the container in one of two ways.

1. You can mount it at /root/.ssh/id_rsa with a mode of 400.
2. You can provide it in the environment variable GIT_SYNC_PRIVATE_KEY and it will be written to the proper location.
