Lyrics

[Verse 1]
When your cluster's acting strange and DNS won't resolve
Pods can't find their services, problems to solve
Time to check the CoreDNS, the heart of naming flow
Two commands will guide you where the answers go

[Chorus]
Get pods first, then logs next
Kube-system namespace text
K-eight-s-app equals kube-dns
Check your CoreDNS, don't stress
Get pods first, then logs next
Find the pods that handle requests

[Verse 2]
Kubectl get pods in the kube-system space
Label selector finds the DNS embrace
K-eight-s-app equals kube-dns will show
Which pods are running, which are good to go

[Chorus]
Get pods first, then logs next
Kube-system namespace text
K-eight-s-app equals kube-dns
Check your CoreDNS, don't stress
Get pods first, then logs next
Find the pods that handle requests

[Bridge]
Once you see the pod names clear
Time for logs to make things appear
Same namespace, same label too
Kubectl logs will show what's true
Errors, warnings, startup pain
CoreDNS secrets logs explain

[Verse 3]
Logs command with the same label selector
Shows you errors like a truth detector
Configuration problems, network delays
CoreDNS logs will light the way

[Chorus]
Get pods first, then logs next
Kube-system namespace text
K-eight-s-app equals kube-dns
Check your CoreDNS, don't stress
Get pods first, then logs next
Find the pods that handle requests

[Outro]
Two commands to rule them all
When DNS begins to fall
Get the pods and get the logs
Clear the DNS naming fog
