#+title: lohr

=lohr= is a Git mirroring tool.

I created it to solve a simple problem I had: I host my own git server at
[[https://git.alarsyo.net]], but want to mirror my public projects to GitHub /
GitLab, for backup and visibility purposes.

GitLab has a mirroring setting, but it doesn't allow for multiple mirrors, as
far as I know. I also wanted my instance to be the single source of truth.

* How it works

Gitea is setup to send webhooks to my =lohr= server on every push update. When
=lohr= receives a push, it clones the concerned repository, or updates it if
already cloned. Then it pushes the update to *all remotes listed* in the [[file:.lohr][.lohr]]
file at the repo root.

** Destructive

This is a very destructive process: anything removed from the single source of
truth is effectively removed from any mirror as well.
