{
test1 = {pkgs, config, ...}:
{
# NixOS config of machine test1
...
};
test2 = {pkgs, config, ...}:
{
# NixOS config of machine test2
...
};
}
And an infrastructure expression, e.g:
{
test1 = {
hostName = "test1.example.org";
system = "i686-linux";
};
test2 = {
hostName = "test2.example.org";
system = "x86_64-linux";
};
}
And by executing:
nixos-deploy-network -n network.nix -i infrastructure.nix
The system configurations in the network expression are built, transferred to the machines in the network and finally activated.
