Daily DevOps Interview Questions Day #71
Daily Interview Questions for SRE and DevOps engineers
Question of the day:
Your application pods in Kubernetes start crash-looping at 3 AM. The logs show generic “Application failed to start” errors with no stack trace. You check the deployment—no recent changes. Resource limits look fine. The pods were running perfectly for weeks.
Pods keep restarting every 2-3 minutes
No obvious errors in application logs
CPU and memory usage well within limits
No recent deployments or config changes
Your team lead asks: “Why did this suddenly start happening?” Walk me through your investigation.
