At 3 AM you are staring at …

What K8s error will ruin your day? 🎡 I got OOMKilled. Which usually means: → limits don’t match reality → and something’s about to restart in production After seeing enough incidents, you realize: these errors aren’t random! They repeat. That’s exactly why we at PerfectScale by DoiT put together a practical troubleshooting guide based on real scenarios. Written by Tania Duggal & Anton Weiss. Illustrations by Adeolu Oyinlola Comment “spin” and I’ll give you your error or skip the guessing → download the full guide: https://lnkd.in/d-QNyWt8 #kubernetes #azure #aws #sre #devops #k8s

How do we debug Kubernetes issues? Expectation: check logs → fix 😎 Reality: 47 terminal tabs open + confusion 🥹 We’ve all been there. Pod running… but not serving traffic Logs look fine… but app is slow Metrics are green… but users are angry Kubernetes isn’t broken. We just don’t know where to look. At 3 AM, we’re not debugging. We’re figuring out where to even start. That’s exactly why PerfectScale by DoiT made this 👇 The Ultimate Kubernetes Troubleshooting Guide: https://lnkd.in/ghWexq4J Real issues. Real fixes.

Every developer's first Kubernetes conversation: Senior engineer: "Don't touch it yet. It will break you." Dev: "OK." Dev five minutes later: "Can I just try one thing?" We've all been that developer. And honestly? That curiosity is exactly what makes good engineers. Nobody learned Kubernetes from a tutorial. They learned it by breaking things. Reading error messages. Breaking things again. The warning was right. The trying was also right. That's just how this works. 😄 Tag the dev on your team who can't resist trying things. 👇

How we troubleshoot Kubernetes deployments? Expectation: too easy 😎 Reality: everything is on fire 🔥 We’ve all been there. Pod stuck in Pending… and we’re guessing why Container logs once… then disappears Latency spikes… but everything looks “fine” Autoscaling behaving… weirdly Kubernetes doesn’t always fail loudly. It fails quietly… and we spend hours finding the signal. At 3 AM, we’re not debugging. We’re figuring out where to even start. That’s why we put this together in 👇 The Ultimate Kubernetes Troubleshooting Guide: https://lnkd.in/dUNJR5Kg Real production issues. Real ways to debug faster.

Everything April Fools taught us about Kubernetes errors… → You can’t “fix them all” → You can’t “just restart” forever → And no… it’s not always DNS (okay… sometimes it is) The truth? Kubernetes isn’t broken. It’s just brutally honest. → CrashLoopBackOff → your app is crashing → OOMKilled → you ran out of memory → Pending → no space for your pod The problem isn’t Kubernetes. It’s how we debug it. Stop guessing. Start reading the signals. If you’ve ever debugged at 3AM… this will save you hours. 👉 Read how:  https://lnkd.in/dUNJR5Kg
