Enabling the docker service

Inside your configuration.nix:

{
  ...
  virtualisation.docker.enable = true;
}

Adding users to the docker group will provide them access to the socket:

{
  users.users.<myuser>.extraGroups = [ "docker" ];
}

Building a docker image with nixpkgs

There is an entry for dockerTools in the nixpkgs manual for reference. In the nixpkgs repo some examples can be found.

Also check out the excellent article by lethalman about building minimal docker images with nix.

Container images with nix

While dockerTools allows to build lightweight containers, it requires nix to be installed on the host system. An alternative are docker images with nix preinstalled, maintained by LnL7.
