For all its flaws, Docker does solve a lot of the pain the author mentions. Deploying postgres, for example, with a config file and keeping it running is really very easy with Docker Compose.

Not affiliated with Docker except for using it, and while I do have some thoughts about design choices made by Docker, it's still a very good tool.

I don't see Docker as an alternative to a configuration manager. For one, turning to containers represents a distinct architectural choice, with a clear set of tradeoffs, that a developer may or may not want to introduce to a project.

It sure does, but even if you choose not to take advantage of container tech, it's still a very easy way to deploy stuff on a single machine. Not sure why the downvotes.

I didn't downvote. I see your point, but it's a bit of a digression, tbf.

I do use Docker, but that is a tool for completely different purpose. I need something else for configuration of all my physical machines; virtual server, physical server, several notebooks and so on.
