# Manual Tunnel Installation

## Step 1: Access Container

```bash
ssh root@192.168.11.12
pct exec 102 -- bash
```

## Step 2: Install cloudflared (if not installed)

```bash
apt update
apt install -y cloudflared
```

## Step 3: Install Tunnel Service with Token

```bash
cloudflared service install eyJhIjoiNTJhZDU3YTcxNjcxYzVmYzAwOWVkZjA3NDQ2NTgxOTYiLCJ0IjoiMTBhYjIyZGEtOGVhMy00ZTJlLWE4OTYtMjdlY2UyMjExYTA1IiwicyI6IlptRXlOMkkyTVRrdE1EZzFNeTAwTkRBNExXSXhaalF0Wm1KaE5XVmpaVEEzTVdGbCJ9
```

## Step 4: Configure Ingress Rules

The token installation creates a basic service. You need to configure ingress rules for all 9 hostnames.

### Option A: Via Cloudflare Dashboard (Recommended)

1. Go to: https://one.dash.cloudflare.com/
2. Zero Trust → Networks → Tunnels
3. Find tunnel: `10ab22da-8ea3-4e2e-a896-27ece2211a05`
4. Click Configure
5. Add all 9 hostnames (see below)

### Option B: Manual Config File

Create `/etc/cloudflared/config.yml`:

```yaml
tunnel: 10ab22da-8ea3-4e2e-a896-27ece2211a05
credentials-file: /root/.cloudflared/<tunnel-id>.json

ingress:
  - hostname: dbis-admin.d-bis.org
    service: http://192.168.11.21:80
    originRequest:
      httpHostHeader: dbis-admin.d-bis.org
  - hostname: dbis-api.d-bis.org
    service: http://192.168.11.21:80
    originRequest:
      httpHostHeader: dbis-api.d-bis.org
  - hostname: dbis-api-2.d-bis.org
    service: http://192.168.11.21:80
    originRequest:
      httpHostHeader: dbis-api-2.d-bis.org
  - hostname: mim4u.org.d-bis.org
    service: http://192.168.11.21:80
    originRequest:
      httpHostHeader: mim4u.org.d-bis.org
  - hostname: www.mim4u.org.d-bis.org
    service: http://192.168.11.21:80
    originRequest:
      httpHostHeader: www.mim4u.org.d-bis.org
  - hostname: rpc-http-prv.d-bis.org
    service: http://192.168.11.21:80
    originRequest:
      httpHostHeader: rpc-http-prv.d-bis.org
  - hostname: rpc-http-pub.d-bis.org
    service: http://192.168.11.21:80
    originRequest:
      httpHostHeader: rpc-http-pub.d-bis.org
  - hostname: rpc-ws-prv.d-bis.org
    service: http://192.168.11.21:80
    originRequest:
      httpHostHeader: rpc-ws-prv.d-bis.org
  - hostname: rpc-ws-pub.d-bis.org
    service: http://192.168.11.21:80
    originRequest:
      httpHostHeader: rpc-ws-pub.d-bis.org
  - service: http_status:404
```

## Step 5: Restart Service

```bash
systemctl restart cloudflared
systemctl status cloudflared
```

## Step 6: Verify

```bash
# Check service status
systemctl status cloudflared

# Check logs
journalctl -u cloudflared -f

# Test endpoints
curl -I https://dbis-admin.d-bis.org
curl -I https://rpc-http-pub.d-bis.org
```
