Domain routing with Cloudflare Tunneling
run application
python3 -m uvicorn main:app --reload --host 0.0.0.0 --port 8081
Before applying manifest file in k8s we need to create the cloudflare authorization Token. Installation on debian: sudo apt install cloudflared
Step 1: cloudflared login to get the cert.pem
cloudflared tunnel login
Step 2 :
cloudflared tunnel create example-tunnel
Step 3:Creating the secret file using the json.
kubectl create secret generic tunnel-credentials --from-file=credentials.json=/home/umesh-khatiwada/.cloudflared/2e86e4f1-562d-4089-88da-87580caa5daf.json
/home/umesh-khatiwada/.cloudflared/2e86e4f1-562d-4089-88da-87580caa5daf.json is
Step 4: Creating the certificate secret.
kubectl create secret generic origin-cert --from-file=origin-cert.pem=/home/umesh-khatiwada/.cloudflared/cert.pem
/home/umesh-khatiwada/.cloudflared/cert.pem is certificate provide by cloudflare.
Step 5:Associate your Tunnel with a DNS record
Go to the DNS tab.
Now create a CNAME targeting .cfargotunnel.com. In this example, the tunnel ID is ef824aef-7557-4b41-a398-4684585177ad, so create a CNAME record specifically targeting ef824aef-7557-4b41-a398-4684585177ad.cfargotunnel.com.
You can also create multiple CNAME records targeting the same Tunnel, if desired.
Alternatively
curl -X POST "https://api.cloudflare.com/client/v4/zones/{ZONE_ID}/dns_records" \
-H "Authorization: Bearer{API_TOKEN}" \
-H "Content-Type: application/json" \
