Building Docker images with Forgejo Actions

Wed, 16 Sep 2026 00:00:00 +0000

Lately I was looking for a Docker registry that I could host locally and keep couple of images that I run on multiple hosts. I didn’t want to run a bare registry but something more complete and I settled on a Forgejo instance which will also make me able to keep Dockerfiles and use it’s integrated CI to build the images.

Forgejo’s CI is based on GitHub Actions (unfortunately - I’d love to see an option to use GitLab CI workflow and syntax instead) so it’s easy to find workflows that can be adapted for your needs. The setup of a runner is not that straightforward, though - Forgejo’s docs are a bit vague so I’ll present a minimal configuration that I got to work properly. For security reasons, I chose to build images with buildah since kaniko is no longer maintained .
