For me it is writting docker compose files describing my services. I like to test them on my machine before pushing them to the server(s). But I guess that’s my own fault for not using something like portainer or even SSHFS.
What’s the most annoying / painful step for you?
Forgetting how x service works when it is dependent on y service which is dependent on the NAS and the NAS broke and you wonder why everything else is broken too.
