Also running Gitea, pretty pleasant experience!
Moved over from Sonatype Nexus to Gitea Packages as well since administering Nexus is annoying: https://docs.gitea.com/usage/packages
However for CI I use WoodpeckerCI (previously used Drone but migrated over), it works well with containers and is delightfully simple: https://woodpecker-ci.org/
Though I guess in my case I don't collaborate with others much outside of work, so it's just something to interact with across computers and servers.
