No, I actually think that is a good analogy. If you just want to have something up and running and use it, that's obviously totally fine and valid, and a good use-case of Docker.
What I take issue with is the attitude which the person I replied to exhibits, the "why would anyone not use docker".
I find that to be a very weird reaction to people doing bare metal. But also I am biased. ~30 Internet facing services, 0 docker in use 😄
OK, but I'd rather be the expert.
And I have no troubling spinning up new services, fast. Currently sitting at around ~30 Internet-facing services, 0 docker containers, and reproducing those installs from scratch + restoring backups would be a single command plus waiting 5 minutes.
