Then whenever Jenkins X needs to create a git repository for an Environment or for a new Project the gitea server will appear in the pick list.
Known gitea limitations
At the time of writing the gitea plugin for Jenkins does not correctly update Pull Request and git commit build statuses which breaks the GitOps promotion pipelines. Promotion can work through manual approval, but the pipeline reports a failure.
Another issue is new projects created by jx inside gitea do not get the merge buttons enabled on Pull Requests. The work around is after a project is created on github you go to the Settings page for the repository inside the gitea web console and enable the merge buttons there.
