[Verse 1]
Pod is crashing, spinning round and round
CrashLoopBackOff brings your cluster down
Check your memory limits, CPU too tight
Storage volumes missing, config not right
Kafka brokers failing, logs will show the way
Resource constraints keeping pods at bay
[Chorus]
Five big problems, learn them well
CRASH and CERT and NETWORK hell
Under-replicated, OPERATOR stuck
REBALANCE storms - you're out of luck
But we'll debug them one by one
Till your Kafka cluster runs
[Verse 2]
Certificates expired, TLS won't connect
Rotation failed, what did you expect?
Check the secret volumes, dates have passed
Trust stores broken, connections don't last
Operator should renew them automatically
But sometimes manual steps set you free
[Chorus]
Five big problems, learn them well
CRASH and CERT and NETWORK hell
Under-replicated, OPERATOR stuck
REBALANCE storms - you're out of luck
But we'll debug them one by one
Till your Kafka cluster runs
[Verse 3]
Network's broken, DNS can't resolve
Firewall blocking, security to solve
Check your service names and namespace calls
Security groups might be building walls
Pods can't reach each other cross the wire
Network policies might block your fire
[Chorus]
Five big problems, learn them well
CRASH and CERT and NETWORK hell
Under-replicated, OPERATOR stuck
REBALANCE storms - you're out of luck
But we'll debug them one by one
Till your Kafka cluster runs
[Verse 4]
Partitions under-replicated, ISR shrinking fast
Brokers can't keep up, performance won't last
Check your replica factor, min-ISR too
Broker health is failing, what will you do?
Replication broken means data at risk
Fix it quickly, don't be brisk
[Verse 5]
Operator stuck, not reconciling state
RBAC permissions seal your fate
CRD versions mismatched, old and new
Cluster operator doesn't know what to do
Check your service accounts, roles and binds
Custom resource definitions in your minds
[Verse 6]
Consumer rebalancing, storms arise
Group coordinator can't synchronize
Too many consumers joining at once
Protocol thrashing, makes you a dunce
Partition assignment takes too long
Rebalance timeout, something's wrong
[Bridge]
From pods to certs to network calls
Under-replication, operator stalls
Consumer chaos, rebalancing pain
But now you know how to fix again
[Chorus]
Five big problems, now you know
CRASH and CERT and NETWORK flow
Under-replicated, OPERATOR clear
REBALANCE storms - nothing to fear
You can debug them one by one
Your Kafka cluster's gonna run
[Outro]
Strimzi mastery in your hands
Troubleshooting helps you understand
Five common issues, solutions bright
Your Kubernetes Kafka's running right
