How to run a docker container at startup under nixos
I would like to run a pre-built docker container under NixOS.
I would like to do this in a Nix-ish way:
- Install the container from docker hub itself via a nix expression, which is thus reproducible. The docker is currently listed as 'latest', I'm hoping that there is some way to go from that to a version id.
- Run the container from startup, by embedding an expression (indirectly) in
/etc/nixos/configuration.nix, presumably via asystemdservice, thus configuring this declaratively.
I have found a few pages about building docker containers from within nix, although I can't even get example number 4 here working. But I haven't found any examples of running containers via the system declaration.
I would really appreciate some help or pointers (or examples!) here, I'm thrashing around a bit trying to make stuff work. I have only a passing familiarity with docker.

Not sure about a 'nix-ish' way but if you just pull the docker image (you can pull a specific version by specifying a tag or a sha256 of the image).
And then either use the docker's daemon functionality to start it up automatically at boot (--restart flag), or you could write a systemd unit file (this unit file might have some integration potential with nixos) to start it for you.
Not a very conclusive answer - but seeing no other answers, hopefully this helps!
