Cloudflare API Setup - Quick Start

Automated Configuration via API

This will configure both tunnel routes and DNS records automatically using the Cloudflare API.

---

Step 1: Get Cloudflare API Credentials

Option A: API Token (Recommended)

1. Go to: https://dash.cloudflare.com/profile/api-tokens
2. Click Create Token
3. Use Edit zone DNS template OR create custom token with:
   • Zone → DNS → Edit
   • Account → Cloudflare Tunnel → Edit
4. Copy the token

Option B: Global API Key (Legacy)

1. Go to: https://dash.cloudflare.com/profile/api-tokens
2. Scroll to API Keys section
3. Click View next to "Global API Key"
4. Copy your Email and Global API Key

---

Step 2: Set Up Credentials

Interactive Setup:

cd /home/intlc/projects/proxmox
./scripts/setup-cloudflare-env.sh

Or manually create .env file:

cat > .env <<EOF
CLOUDFLARE_API_TOKEN="your-api-token-here"
DOMAIN="d-bis.org"
TUNNEL_TOKEN="eyJhIjoiNTJhZDU3YTcxNjcxYzVmYzAwOWVkZjA3NDQ2NTgxOTYiLCJ0IjoiMTBhYjIyZGEtOGVhMy00ZTJlLWE4OTYtMjdlY2UyMjExYTA1IiwicyI6IlptRXlOMkkyTVRrdE1EZzFNeTAwTkRBNExXSXhaalF0Wm1KaE5XVmpaVEEzTVdGbCJ9"
EOF

chmod 600 .env

---

Step 3: Run Configuration Script

cd /home/intlc/projects/proxmox
./scripts/configure-cloudflare-api.sh

What it does:

1. ✅ Gets zone ID for d-bis.org
2. ✅ Gets account ID
3. ✅ Extracts tunnel ID from token
4. ✅ Configures 4 tunnel routes (rpc-http-pub, rpc-ws-pub, rpc-http-prv, rpc-ws-prv)
5. ✅ Creates/updates 4 DNS CNAME records
6. ✅ Enables proxy on all DNS records

---

What Gets Configured

Tunnel Routes:

• rpc-http-pub.d-bis.org → https://192.168.11.251:443
• rpc-ws-pub.d-bis.org → https://192.168.11.251:443
• rpc-http-prv.d-bis.org → https://192.168.11.252:443
• rpc-ws-prv.d-bis.org → https://192.168.11.252:443

DNS Records:

• All 4 endpoints → CNAME → <tunnel-id>.cfargotunnel.com (🟠 Proxied)

---

Troubleshooting

"Could not determine account ID"

Add to .env:

CLOUDFLARE_ACCOUNT_ID="your-account-id"

Get account ID from: Cloudflare Dashboard → Right sidebar → Account ID

"API request failed"

• Verify API token has correct permissions
• Check token is not expired
• Verify domain is in your Cloudflare account

"Zone not found"

• Verify domain d-bis.org is in your Cloudflare account
• Or set CLOUDFLARE_ZONE_ID in .env

---

Verify Configuration

After running the script:

1. Check Tunnel Routes:

   • Zero Trust → Networks → Tunnels → Your Tunnel → Configure
   • Should see 4 public hostnames

2. Check DNS Records:

   • DNS → Records
   • Should see 4 CNAME records (🟠 Proxied)

3. Test Endpoints:

   curl https://rpc-http-pub.d-bis.org/health
