# 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"]' --decrypt "$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'"]' --decrypt "$SCRIPT_DIR/secrets.yaml" >"./etc/ssh/$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"]' --decrypt "$SCRIPT_DIR/secrets.yaml"
```

| Name | Description | Type | Default | Required |
| --------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------- | -------- | :------: |
| [debug\_logging](#input_debug_logging) | Enable debug logging | `bool` | `false` | no |
| [deployment\_ssh\_key](#input_deployment_ssh_key) | Content of private key used to deploy to the target\_host after initial installation. To ensure maximum security, it is advisable to connect to your host using ssh-agent instead of relying on this variable | `string` | `null` | no |
| [disk\_encryption\_key\_scripts](#input_disk_encryption_key_scripts) | Each of these script files will be executed locally and the output of each of them will be made present at the given path to disko during installation. The keys will be not copied to the final system | list(object({
path = string
script = string
})) | `[]` | no |
| [extra\_environment](#input_extra_environment) | Extra environment variables to be set during installation. This can be usefull to set extra variables for the extra\_files\_script or disk\_encryption\_key\_scripts | `map(string)` | `{}` | no |
| [extra\_files\_script](#input_extra_files_script) | A script file that prepares extra files to be copied to the target host during installation. The script expected to write all its files to the current directory. This directory is copied to the target host during installation to the / directory. | `string` | `null` | no |
| [file](#input_file) | Nix file containing the nixos\_system\_attr and nixos\_partitioner\_attr. Use this if you are not using flake | `string` | `null` | no |
| [install\_ssh\_key](#input_install_ssh_key) | Content of private key used to connect to the target\_host during initial installation | `string` | `null` | no |
| [install\_user](#input_install_user) | SSH user used to connect to the target\_host, before installing NixOS. If null than the value of `target_host` is used | `string` | `null` | no |
| [instance\_id](#input_instance_id) | The instance id of the target\_host, used to track when to reinstall the machine | `string` | `null` | no |
| [kexec\_tarball\_url](#input_kexec_tarball_url) | NixOS kexec installer tarball url | `string` | `null` | no |
| [nix\_options](#input_nix_options) | the options of nix | `map(string)` | `{}` | no |
| [nixos\_partitioner\_attr](#input_nixos_partitioner_attr) | Nixos partitioner and mount script i.e. your-flake#nixosConfigurations.your-evaluated-nixos.config.system.build.diskoNoDeps or just your-evaluated.config.system.build.diskNoDeps. `config.system.build.diskNoDeps` is provided by the disko nixos module | `string` | n/a | yes |
| [nixos\_system\_attr](#input_nixos_system_attr) | The nixos system to deploy i.e. your-flake#nixosConfigurations.your-evaluated-nixos.config.system.build.toplevel or just your-evaluated-nixos.config.system.build.toplevel if you are not using flakes | `string` | n/a | yes |
| [no\_reboot](#input_no_reboot) | Do not reboot after installation | `bool` | `false` | no |
| [stop\_after\_disko](#input_stop_after_disko) | Exit after disko formatting | `bool` | `false` | no |

| [target\_user](#input_target_user) | SSH user used to connect to the target\_host after installing NixOS. If install\_user is not set than this user is also used before installing. | `string` | `"root"` | no |
