Im probably the opposite of you! Started using docker at home after messing up my raspberry pi a few too many times trying stuff out, and not really knowing what the hell I was doing. Since moved to a proper nas, with (for me, at least) plenty of RAM.
Love the ability to try out a new service, which is kind of self-documenting (especially if I write comments in the docker-compose file). And just get rid of it without leaving any trace if it’s not for me.
Added portainer to be able to check on things from my phone browser, grafana for some pretty metrics and graphs, etc etc etc.
And now at work, it’s becoming really, really useful, and I’m the only person in my (small, scientific research) team who uses containers regularly. While others are struggling to keep their fragile python environments working, I can try out new libraries, take my env to the on-prem HPC or the external cloud, and I don’t lose any time at all. Even “deployed” some little utility scripts for folks who don’t realise that they’re actually pulling my image from the internal registry when they run it. A much, much easier way of getting a little time-saving script into the hands of people who are forced to use Linux but don’t have a clue how to use it.
