Incus is a next generation system container and virtual machine manager. It is a community driven alternative to Canonical's LXD.
Linux containers provides installation instructions, including for nixos [1]. Wide variety of linux distro images are available, including for NixOS [2].
NixOS image
There is a pre-built NixOS image available at https://images.linuxcontainers.org/ providing both stable and unstable NixOS distributions.
To list available nixos images you can use incus image list command:
$ incus image list images:nixos +-------------------------------+--------------+--------+---------------------------------------+--------------+-----------------+-----------+-------------------------------+ | ALIAS | FINGERPRINT | PUBLIC | DESCRIPTION | ARCHITECTURE | TYPE | SIZE | UPLOAD DATE | +-------------------------------+--------------+--------+---------------------------------------+--------------+-----------------+-----------+-------------------------------+ | nixos/23.11 (3 more) | 4a84a70fb432 | yes | Nixos 23.11 amd64 (20240216_01:02) | x86_64 | CONTAINER | 128.94MiB | Feb 16, 2024 at 12:00am (UTC) | +-------------------------------+--------------+--------+---------------------------------------+--------------+-----------------+-----------+-------------------------------+ | nixos/23.11 (3 more) | cee1d901cca2 | yes | Nixos 23.11 amd64 (20240216_01:02) | x86_64 | VIRTUAL-MACHINE | 467.54MiB | Feb 16, 2024 at 12:00am (UTC) | +-------------------------------+--------------+--------+---------------------------------------+--------------+-----------------+-----------+-------------------------------+ | nixos/23.11/arm64 (1 more) | 0881cc69ae39 | yes | Nixos 23.11 arm64 (20240216_01:03) | aarch64 | VIRTUAL-MACHINE | 474.89MiB | Feb 16, 2024 at 12:00am (UTC) | +-------------------------------+--------------+--------+---------------------------------------+--------------+-----------------+-----------+-------------------------------+ | nixos/23.11/arm64 (1 more) | c436a2e0a0e3 | yes | Nixos 23.11 arm64 (20240216_01:03) | aarch64 | CONTAINER | 123.78MiB | Feb 16, 2024 at 12:00am (UTC) | +-------------------------------+--------------+--------+---------------------------------------+--------------+-----------------+-----------+-------------------------------+ | nixos/unstable (3 more) | 711ad413f1d4 | yes | Nixos unstable amd64 (20240216_01:03) | x86_64 | VIRTUAL-MACHINE | 467.31MiB | Feb 16, 2024 at 12:00am (UTC) | +-------------------------------+--------------+--------+---------------------------------------+--------------+-----------------+-----------+-------------------------------+ | nixos/unstable (3 more) | b15681a4f2cf | yes | Nixos unstable amd64 (20240216_01:03) | x86_64 | CONTAINER | 174.39MiB | Feb 16, 2024 at 12:00am (UTC) | +-------------------------------+--------------+--------+---------------------------------------+--------------+-----------------+-----------+-------------------------------+ | nixos/unstable/arm64 (1 more) | 95242674aa96 | yes | Nixos unstable arm64 (20240216_01:03) | aarch64 | VIRTUAL-MACHINE | 475.38MiB | Feb 16, 2024 at 12:00am (UTC) | +-------------------------------+--------------+--------+---------------------------------------+--------------+-----------------+-----------+-------------------------------+ | nixos/unstable/arm64 (1 more) | c0a02e8fd464 | yes | Nixos unstable arm64 (20240216_01:03) | aarch64 | CONTAINER | 168.44MiB | Feb 16, 2024 at 12:00am (UTC) | +-------------------------------+--------------+--------+---------------------------------------+--------------+-----------------+-----------+-------------------------------+
To launch a new NixOS container use the following command:
incus launch images:nixos/unstable nixos -c security.nesting=true
security.nesting=true is needed for nix to work correctly.
Image is built using linuxcontainers CI job [3], the source of which can be found here [4]. As we can see jenkins CI job downloads lxdVirtualMachineImage derivation produced by hydra, which produces qcow2 image file. Configuration for nixos image can be found here [5].
