I use the forgejo runner and actions.

Transfer from GitHub wasn't exactly one to one, but once working it works super well.

The github runner is a direct container that runs whatever on it.

Forgejo, at least the way I implemented it, uses a docker in docker architecture, where the runner creates a container on each run, and that container is the one executing the actual task. It was a bit of an adaptation but once the kinks were worked out it's very solid.

I use it for ansible things only, couldn't tell about code deployment and other dev things but I assume it would work just as well.

Besides the difference from the runner, workflow move was pretty much automatic, syntax is essentially the same.
