> To add to what you said, I suspect that Docker containers are much easier to configure than OS packages because they are all to some extent Twelve Factor compliant, which means that configuration and operations are simplified. Yeah, I think that's got something to do with it. At the very least, you practically have to document right up front where all the config affecting the container lives, both files and env vars. It's also tempting to put the most commonly-used config items in env vars, if they weren't already. Consequently, dockerized Samba, for example, is the easiest config of that daemon that I've ever performed, for any of my never-unusual-or-complex use cases, including with GUI tools, over a couple decades of using it.
