# All-in-one
|
|
|
|
Combines the install and nixos-rebuild module in one interface to install NixOS
|
|
with nixos-anywhere and then keep it up-to-date with nixos-rebuild.
|
|
|
|
## Example
|
|
|
|
```hcl
|
|
locals {
|
|
ipv4 = "192.0.2.1"
|
|
}
|
|
|
|
module "deploy" {
|
|
source = "github.com/nix-community/nixos-anywhere//terraform/all-in-one"
|
|
# with flakes
|
|
nixos_system_attr = ".#nixosConfigurations.mymachine.config.system.build.toplevel"
|
|
nixos_partitioner_attr = ".#nixosConfigurations.mymachine.config.system.build.diskoScript"
|
|
# without flakes
|
|
# file can use (pkgs.nixos []) function from nixpkgs
|
|
#file = "${path.module}/../.."
|
|
#nixos_system_attr = "config.system.build.toplevel"
|
|
#nixos_partitioner_attr = "config.system.build.diskoScript"
|
|
|
|
target_host = local.ipv4
|
|
# when instance id changes, it will trigger a reinstall
|
|
instance_id = local.ipv4
|
|
# useful if something goes wrong
|
|
# debug_logging = true
|
|
# script is below
|
|
extra_files_script = "${path.module}/decrypt-ssh-secrets.sh"
|
|
disk_encryption_key_scripts = [{
|
|
path = "/tmp/secret.key"
|
|
# script is below
|
|
script = "${path.module}/decrypt-zfs-key.sh"
|
|
}]
|
|
}
|
|
```
|
|
|
|
_Note:_ You need to mark scripts as executable (`chmod +x`)
|
|
|
|
### ./decrypt-ssh-secrets.sh
|
|
|
|
```bash
|
|
#!/usr/bin/env bash
|
|
|
|
mkdir -p etc/ssh var/lib/secrets
|
|
|
|
SCRIPT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null 2>&1 && pwd )"
|
|
|
|
umask 0177
|
|
sops --extract '["initrd_ssh_key"]' -d "$SCRIPT_DIR/secrets.yaml" >./var/lib/secrets/initrd_ssh_key
|
|
|
|
# restore umask
|
|
umask 0022
|
|
|
|
for keyname in ssh_host_rsa_key ssh_host_rsa_key.pub ssh_host_ed25519_key ssh_host_ed25519_key.pub; do
|
|
if [[ $keyname == *.pub ]]; then
|
|
umask 0133
|
|
else
|
|
umask 0177
|
|
fi
|
|
sops --extract '["'$keyname'"]' -d "$SCRIPT_DIR/secrets.yaml" >"./etc/ssh/$keyname"
|
|
done
|
|
```
|
|
|
|
### ./decrypt-zfs-key.sh
|
|
|
|
```bash
|
|
#!/usr/bin/env bash
|
|
|
|
set -euo pipefail
|
|
|
|
SCRIPT_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" >/dev/null 2>&1 && pwd )"
|
|
cd "$SCRIPT_DIR"
|
|
sops --extract '["zfs-key"]' -d "$SCRIPT_DIR/secrets.yaml" >"./etc/ssh/$keyname"
|
|
```
