Configuring a new host

Remotely using nixos-anywhere

A host can be configured remotely using nixos-anywhere and disko.

1. Pre-provision the SSH keys used by SOPS

# Create a temporary directory with the correct permissions
install -d -m755 "./tmp/persist/etc/ssh"

# Generate the desired SSH keys in the created directory
ssh-keygen -t ed25519 -f "./tmp/persist/etc/ssh/ssh_host_ed25519_key" -N "" -C "<USER>@<HOST>"
ssh-keygen -t rsa -b 4096 -f "./tmp/persist/etc/ssh/ssh_host_rsa_key" -N "" -C "<USER>@<HOST>"

# Ensure that the SSH keys have the appropriate permissions
chmod 600 ./tmp/persist/etc/ssh/*

2. Update the SOPS config (.sops.yaml) with the newly generated key

# Add the output of this command to the .sops.yaml file
cat ./tmp/persist/etc/ssh/ssh_host_ed25519_key.pub | ssh-to-age

# Update the relevant secrets files with the new key
sops updatekeys PATH/TO/SECRETS.yml

3. Configure the host

nixos-anywhere --extra-files ./tmp --flake '.#<hostname>' <user>@<ip-address>
