Container Management
NixOS allows you to easily run other NixOS instances as containers. Containers are a light-weight approach to virtualisation that runs software in the container at the same speed as in the host system. NixOS containers share the Nix store of the host, making container creation very efficient.
::: {.warning} Currently, NixOS containers are not perfectly isolated from the host system. This means that a user with root access to the container can do things that affect the host. So you should not give container root access to untrusted users. :::
NixOS containers can be created in two ways: imperatively, using the
command nixos-container, and declaratively, by specifying them in your
configuration.nix. The declarative approach implies that containers
get upgraded along with your host system when you run nixos-rebuild,
which is often not what you want. By contrast, in the imperative
approach, containers are configured and updated independently from the
host system.
