Use a VM to run this example

Build VM with:

nixos-rebuild build-vm --fast -I nixos-config=./configuration.nix -I nixpkgs=.

Start VM with:

QEMU_NET_OPTS="hostfwd=tcp::2222-:22" ./result/bin/run-nixos-vm

User is nixos, password is nixos.

Ssh into VM with ssh -p 2222 nixos@localhost.

If you get into issues with ssh trying too many public keys and failing, try instead: ssh -o PasswordAuthentication=yes -o PreferredAuthentications=keyboard-interactive,password -o PubkeyAuthentication=no -p 2222 nixos@localhost.

For more information about running this example in a vm, see NixOS_modules#Developing_modules.

For more information about writing tests, see the manual.

Create your secret key which prints the public key used for admin:

nix-shell -p age --run 'age-keygen -o keys.txt'

Get target host age key which prints the public key used for vm:

nix-shell -p ssh-to-age --run 'ssh-keyscan -p 2222 -4 localhost | ssh-to-age'

Update admin and vm keys in sops.yaml.

Edit secret itself with:

nix-shell -p sops --run 'sops --config sops.yaml secrets.yaml'

Deploy with:

nix-shell -p colmena --run 'colmena apply'

Took 12 minutes for first deploy on my machine. Next deploys take about 12 seconds.
