The command nixos-container can now create containers. For instance,
the following creates and starts a container named ‘database’:
$ nixos-container create database
The configuration of the container is stored in
/var/lib/containers/<name>/etc/nixos/configuration.nix. After editing
the configuration, you can make the changes take effect by doing
$ nixos-container update database
The container can also be destroyed:
$ nixos-container destroy database
Containers are now executed using a template unit,
‘container@.service’, so the unit in this example would be
‘container@database.service’.
