Kubernetes Crash Recovery Guide
How often do we get a chance to build things in Kubernetes?
10% of the time?
15% of the time?
Max 20% of the time.
The other 80% of our time goes into operations, upgrades, maintenance, troubleshooting isn't it?
Seldom do I see teams preparing or educating existing or new team members on the aspects needed to handle firefighting better.
Rather than giving it in fragments, I prepared a thoughtful and intuitive 68-page Kubernetes Crash Recovery Guide to address this gap.
Topics Covered:
1. Introduction
2. Kubernetes Architecture Simplified
3. Kubernetes Mistakes Side Effects
4. Kubernetes POD Lifecycle
5. Understanding Kubernetes Logs (with Cluster level logging architectures)
6. How To Handle Most Common Errors
- ImagePullBackOff

- Node Not Ready
7. POD Troubleshooting Tactics
8. Must Know K8s Troubleshooting Commands
Hope this serves as a valuable resource to improve your Kubernetes troubleshooting skills.
