+ Installing into a nspawn container
+
+
+ For installing a NixOS into a systemd nspawn container the NixOS installation tools are needed.
+ If you run another distribution than NixOS on your host,
+ please follow steps 1, 2, and 3.
+
+
+
+ Create a NixOS configuration file /var/lib/machines/my-container/etc/nixos/configuration.nix.
+ It is important that the container root file system is under /var/lib/machines.
+ This is the standard location where machinectl will look for containers.
+ If you choose place the root into another location you need to start the container directly with systemd-nspawn.
+ The file needs to have at least following options enabled:
+
+ = true;
+ = true;
+
+ If your host uses systemd-networkd to configure the network,
+ you can also enable to use networkd default network configuration for your host and container.
+
+
+
+ Install the container by running following command:
+ nixos-install --root /var/lib/machines/my-container \
+ --no-channel-copy --no-root-passwd --no-bootloader
+
+
+
+ Start the container by running following command:
+ machinectl start my-container
+
+
