🚨 I’ve interviewed 100 DevOps engineers. Most of them say, “I’ve done Kubernetes in production.” But when the real questions start, they freeze. Here’s what I ask 👇 1. How does DNS resolution work inside a pod? → And what’s the first thing you check when a service isn’t reachable by name? 2. Please walk me through the controller manager’s role during a Deployment. → Not just kubectl rollout status, I want the reconciliation logic. 3. What happens if a node with local storage gets autoscaled down? → Hint: this is where most real prod data loss stories begin. 4. Post-deploy, latency spikes for 30% of users. No errors. No logs. No alerts. → What’s your 3-step triage? 5. How do you enforce runtime security in Kubernetes? → PSP? AppArmor? OPA? Or… just crossing fingers? 6. HPA vs VPA vs Karpenter; when would you NOT use each? → Bonus: How do you simulate HPA behavior in staging? 7. Tell me about the last Kubernetes outage you debugged. → No postmortem? You probably weren’t in the war room. If you’re reading this thinking, “I should know this…”, that’s your signal.

💡 I’ve interviewed 100 DevOps engineers. Most of them say, “I’ve done K8s in production.” But when the real questions come in, they freeze. Here’s what I ask 1. How does DNS resolution work inside a pod? → And what do you check when a service isn’t reachable by name? 2. Walk me through what the controller manager does during a Deployment. → No rollout status. Reconciliation logic. 3. What happens if a node with local storage gets autoscaled down? → Be careful. This one causes data loss in prod more often than you’d think. 4. Post-deploy, latency spikes for 30% of users. No errors. No logs. What now? → Your answer reveals if you know how to triage chaos. 5. How do you enforce runtime security in Kubernetes? → PSP? AppArmor? OPA? Most people just hope for the best. 6. HPA vs VPA vs Karpenter; when would you NOT use each? → Bonus: How would you simulate HPA behavior in staging? 7. Tell me about the last outage you debugged in Kubernetes. → No postmortem? You weren’t there. If you’re reading this and thinking, “I should know this…” That’s your signal to stop winging it. #Kubernetes #DevOpsInterviews #RealTalkDevOps #SREThinking #CI_CD

#DevOps Diaries #130 If I had to recommend ONE single AWS service you should learn first… my answer is always IAM. Without proper IAM, nothing else in AWS really matters. I was recently talking to a friend who strongly argued for VPC first. His point was is okay as VPC is important. But here’s the reality: You can build and run services without a custom VPC( lots of managed services ). But without IAM? You’re completely stuck. You can’t create resources, you can’t assign permissions, you can’t secure anything, and every single service becomes useless. IAM is the foundation of AWS security and access control. Everything else sits on top of it. So my strong advice: Don’t just “learn” IAM ==> Be a Master in IAM Understand: - Users, Groups, Roles & Policies - IAM Identity Center (SSO) - IAM Access Analyzer - Least Privilege principle - Policy evaluation logic - Resource-based vs Identity-based policies Trust me : the time you invest in mastering IAM will save you hundreds of hours of debugging weird permission errors later.

#DevOps Diaries #129 You’re setting up CloudFront and want to add a WAF on it for protection! You create the Web ACL in your usual region (us-west-2, eu-west-1, wherever you normally work) and try to attach it to the distribution. ---> You'll get error. “Invalid Web ACL” or “Web ACL not found”. WTF? CloudFront is global, right? Should work anywhere.!! Here’s the catch (and it bites everyone once): AWS only lets you attach WAF Web ACLs that were created in us-east-1 (N. Virginia) to CloudFront distributions. Even if your origin is in Mumbai or Frankfurt, the WAF itself has to live in us-east-1. Lesson: Always spin up your CloudFront WAFv2 Web ACLs in us-east-1. . Don’t waste 30 minutes debugging like I did last week Saves headaches, keeps your pipeline clean.
