Challenge
Configure Readiness and Liveness Probes
- Add a readiness probe on / for web-deploy using HTTP GET.
- Add a liveness probe with initial delay of 5s and 3s interval.
- Observe Pod behavior when readiness probe fails.
- Use kubectl describe pod to inspect probe configuration.
-
Challenge
Use Ingress to Route Traffic
- Create an Ingress resource web-ingress to route /web to web-svc.
- Ensure the correct IngressClassName is defined.
- Verify path-based routing via curl or browser.
- Troubleshoot 404 errors using kubectl describe ingress.
