I use Ansible to meet this need. Whenever I want to deploy to one or more remote hosts, I run Ansible locally and it connects via SSH to the remote host(s). There, it can run Docker Compose, configure services, lay down files on the host, restart things, etc.
I develop a moderately popular open source project and self-host it on Gitea. But I also mirror it on GitHub and accept PRs there. And one PR submitter on GitHub said they preferred to contribute there because that’s where potential employers look for open source activity.
Could employers also look on Gitea/Forgejo? In theory, yes. But some of them literally ask for your GitHub profile on their application forms…
