# Runbook: Provisioning a New Host

Steps for adding a new machine to the infrastructure.

## NixOS host on Proxmox

```bash
# 1. Use the PXE boot menu or installer ISO
#    The auto-installer at pxe-boot.sweet.home presents all flake targets.

# 2. Add to nixos/ flake if a new build-type is needed
#    Otherwise pick the closest existing target (e.g. proxmox-minimal)

# 3. Add SSH host key to clan vars (enables SOPS decryption)
cd nixos
./scripts/sync-host-keys.sh <target>

# 4. Create the VM/LXC via Terraform
cd ../terraform/proxmox
# Add a resource block in the appropriate .tf file
terraform plan
terraform apply

# 5. Deploy NixOS
nixos-rebuild switch --flake ./nixos#<target> --target-host <hostname>
```

## Non-NixOS host (Proxmox VM)

```bash
# 1. Create VM in Proxmox (manually or via terraform)
# 2. Add to ansible/inventory/hosts.yml with correct group
# 3. Add SSH key, verify connectivity:
ansible-playbook ansible/playbooks/ping.yml --limit <hostname>
# 4. Apply the role:
ansible-playbook ansible/playbooks/<role>.yml --limit <hostname> --check --diff
ansible-playbook ansible/playbooks/<role>.yml --limit <hostname>
```

## Adding Ansible inventory entry

```yaml
# ansible/inventory/hosts.yml — under the appropriate group:
new-host.sweet.home:
  ansible_user: wayne
  # any role-specific variables
```

## IPA enrollment (for any new host)

```bash
# On the new host (after OS install):
sudo ipa-client-install \
  --server=domain-controller.sweet.home \
  --domain=sweet.home \
  --realm=SWEET.HOME \
  --principal=admin \
  --mkhomedir
```
