# NetBird GitOps Reconciler — PoC Deployment

Ansible playbook that deploys a self-contained stack on VPS-A for end-to-end
testing of the NetBird GitOps reconciler.

## Stack overview

| Component  | Purpose                                     |
| ---------- | ------------------------------------------- |
| Caddy      | TLS termination, reverse proxy              |
| NetBird    | Management, Signal, Relay, Dashboard, TURN  |
| Reconciler | Declarative config → NetBird API reconciler |
| Gitea      | Local Git server (optional, off by default) |

All services run as Docker containers on a single VPS, connected via a `netbird`
Docker bridge network. Caddy handles ACME certificates automatically.

## Prerequisites

- SSH access to `46.225.220.61` (root, key-based)
- DNS A record: `vps-a.networkmonitor.cc` → `46.225.220.61`
- `rsync` installed locally (used to sync reconciler source)
- Ansible 2.15+ with `community.general` and `ansible.posix` collections

Install collections if needed:

```bash
ansible-galaxy collection install community.general ansible.posix
```

## Setup

### 1. Create vault file

```bash
cd poc/ansible
cp group_vars/all/vault.yml.example group_vars/all/vault.yml
```

For the first deploy, leave all values as empty strings — the playbook
auto-generates NetBird secrets and a reconciler token.

### 2. Deploy

```bash
cd poc/ansible
ansible-playbook -i inventory.yml playbook.yml
```

The playbook will:

1. Generate secrets (encryption key, TURN password, relay secret, reconciler
   token)
2. Install Docker if not present
3. Configure UFW firewall
4. Rsync the reconciler source code to VPS-A
5. Template all config files
6. Build the reconciler Docker image on VPS-A
7. Pull NetBird/Gitea images and start all services
8. Run health checks and print a summary with generated secrets

**Save the generated secrets** printed at the end into `vault.yml` so subsequent
runs are idempotent.

### 3. Create NetBird admin + API token

1. Open `https://vps-a.networkmonitor.cc` in a browser
2. Create the first admin account (embedded IdP — no external OAuth)
3. Go to **Settings → Personal Access Tokens → Generate**
4. Copy the token into `vault.yml` as `vault_netbird_api_token`
5. Re-run the playbook:

```bash
ansible-playbook -i inventory.yml playbook.yml
```

The reconciler will now start successfully with a valid API token.

### 4. (Optional) Enable Gitea

To enable Gitea-backed GitOps polling:

1. Open `http://vps-a.networkmonitor.cc:3000` and complete the install wizard
2. Create an admin account (user: `blastpilot`)
3. Create org `BlastPilot` and repo `netbird-gitops`
4. Push `netbird.json` to the repo
5. Generate a Gitea API token (Settings → Applications)
6. In `vars.yml`, set `gitea_enabled: "true"`
7. In `vault.yml`, fill in `vault_gitea_token` and `vault_gitea_admin_password`
8. Re-run the playbook

## Testing

All commands below assume you have the reconciler token. Replace `<TOKEN>` with
the value of `vault_reconciler_token`.

### Health check

```bash
curl https://vps-a.networkmonitor.cc/reconciler/health
```

### Dry-run reconcile

```bash
curl -X POST \
  -H "Authorization: Bearer <TOKEN>" \
  -H "Content-Type: application/json" \
  -d @ansible/files/netbird-seed.json \
  'https://vps-a.networkmonitor.cc/reconciler/reconcile?dry_run=true'
```

### Apply reconcile

```bash
curl -X POST \
  -H "Authorization: Bearer <TOKEN>" \
  -H "Content-Type: application/json" \
  -d @ansible/files/netbird-seed.json \
  'https://vps-a.networkmonitor.cc/reconciler/reconcile'
```

### Export current state

```bash
curl -H "Authorization: Bearer <TOKEN>" \
  'https://vps-a.networkmonitor.cc/reconciler/export'
```

### Enroll a peer

Use a setup key from the reconcile response (`created_keys` field):

```bash
sudo netbird up --management-url https://vps-a.networkmonitor.cc --setup-key <KEY>
```

## Teardown

Remove all containers and volumes:

```bash
ssh root@46.225.220.61 "cd /opt/netbird-poc && docker compose down -v"
```
