Docker serves the basic functionality of a container as well as any other. The workflows that forced you to migrate away from it are more complicated, I’m sure, than a procedurally defined dev environment. What you’re calling a snapshot is what I meant when I said reproducible. Images allow me to have reproducible starting points to add other parts to my environment. Over time they get out of date depending on exactly what happens, but it’s much more controllable than a basic Ubuntu installation. Your comment further pushes me away from Nix, really, even without mentioning it. It makes it seem even more like a tool that’s not for me, but rather for much more complicated things. |

I disagree. We've had multiple production outages caused by the Docker daemon misbehaving (usually causing us to run out of disk space). It also makes operations far more difficult than necessary; e.g. want to copy a .tar.gz file to AWS? Sorry, Docker's gonna insert itself in the workflow, and over-complicate the authentication[1]. Instead, I have a script which runs [2] in a loop; much easier!

The container I mentioned literally just runs `java -jar` with a pre-built .jar file. Nothing fancy. Still, I have no idea what it's running, since Docker allows mutable tags, and there's no reference to a version number, let alone a git revision.

I wasn't talking about Nix, I was talking about Docker. They're very different tools (Docker manages running processes/containers; Nix describes the contents of files). I just really hate Docker, and am baffled when people say it's "easy".

You're giving me too much credit. It took me days to even get Docker installed. It turned out that despite a mountain of documentation telling me to install "Docker Machine", that's actually been discontinued for years and I should have been installing "Docker Desktop" instead.
