For those who have even simpler needs (like side projects, or 1 dev projects), I found using simply docker and git to be plenty enough.
Basically, you can create a bare git repository on your server (`git init --bare`), and put a `hooks/post-receive` script within it that will clone sources in a temporary directory, build the docker image and rotate containers. That way, you can `git push` to build and deploy, and it's easy to migrate server.
The added bonus is that you now have a central git repos that can act as backup, so you don't need github or gitlab.
The main painpoint, which I find dokku interesting for (and I assume caprover too) is zero-downtime deployment. But well, if this is critical, you probably need something more extensive.
