DNS

To troubleshooting DNS, you could use the testing/dns.yaml manifest. Edit the nodeSelector section to specify on which node you want deploy the pod.

Then, perform some tests:

❯ kubectl exec -i -t dnsutils -- nslookup kubernetes.default
Server:         10.43.0.10
Address:        10.43.0.10#53

Name:   kubernetes.default.svc.cluster.local
Address: 10.43.0.1

❯ kubectl exec -i -t dnsutils -- nslookup github.com
Server:         10.43.0.10
Address:        10.43.0.10#53
