# 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        | Git server for GitOps source-of-truth       |
| Gitea Runner | Executes CI workflows (Actions)             |

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 records:
  - `vps-a.networkmonitor.cc` → `46.225.220.61`
  - `gitea.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
```

## Deployment (multi-phase)

The deployment is intentionally multi-phase because some tokens can only be
obtained after services are running.

### Phase 1: Initial deploy

```bash
cd poc/ansible
cp group_vars/all/vault.yml.example group_vars/all/vault.yml
ansible-playbook -i inventory.yml playbook.yml
```

The playbook will:

1. Generate secrets (encryption key, TURN password, relay secret, reconciler
   token)
2. Install Docker, configure UFW
3. Rsync the reconciler source code and build the Docker image
4. Template configs and start all services
5. Skip the Gitea Actions runner (no token yet)
6. Print a summary with generated secrets

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

### Phase 2: 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`

### Phase 3: Set up Gitea

1. Open `https://gitea.vps-a.networkmonitor.cc` and complete the install wizard
2. Create an admin account (user: `blastpilot`)
3. Create org `BlastPilot` and repo `netbird-gitops`
4. Generate a Gitea API token (**Settings → Applications**) →
   `vault_gitea_token`
5. Go to **Site Administration → Actions → Runners** → copy runner registration
   token → `vault_gitea_admin_password` and `vault_gitea_runner_token`

### Phase 4: Re-deploy with all tokens

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

This run will:

- Start the reconciler with a valid NetBird API token
- Register and start the Gitea Actions runner
- Wire the reconciler to poll Gitea for `netbird.json` changes

### Phase 5: Push code and test CI

```bash
cd /path/to/netbird-gitops
git remote add poc git@gitea.vps-a.networkmonitor.cc:BlastPilot/netbird-gitops.git
git push poc main
```

Then configure Gitea repo secrets (Settings → Actions → Secrets):

- `RECONCILER_TOKEN` — the reconciler bearer token
- `RECONCILER_URL` — `https://vps-a.networkmonitor.cc/reconciler`
- `GITEA_TOKEN` — same Gitea API token

Create a branch, modify `netbird.json`, open a PR — the dry-run workflow should
post a plan as a PR comment.

## Testing

Replace `<TOKEN>` with `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'
```

## Teardown

Remove all containers and volumes:

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

Stop the runner:

```bash
ssh root@46.225.220.61 "systemctl stop gitea-runner && systemctl disable gitea-runner"
```
