git_mirrorer

Mirror two git remotes

(alternate description: containerize everything!)

What it does

It periodically fetches an origin repo. If the last commit of a branch on the watchlist changed, it pushes that branch to the destination. It does not need to checkout or pull everything locally.

How to use

Whether you use a container or call the Python script directly, set the following parameters as environment variables:

• ORIGIN_URL: remote URL of the origin repo
• DESTINATION_URL: remote URL of the destination repo
• BRANCHES_LIST: list of branches to update, e.g. [branch1,branch2,branch3]
• UPDATE_PERIOD: delay between updates (seconds) [default: 60]

Authentication

This currently expects one-time authentication methods in the remote URL itself. It does not currently use GIT_ASKPASS.

• tokens on GitHub (e.g. remote URL: https://<token>@github.com/<username>/<repo>.git)
• username/password authentication over HTTPS (e.g. remote URL: https://<username>:<password>@github.com/<username>/<repo>.git) or SSH
