Mastering the K8s Maze: 50 Concepts to Level Up Your DevOps Game!
These components form the "brain" and skeletal structure of any Kubernetes environment.
Best Practices and Troubleshooting
- 30. Labeling and Annotations: Organizing and providing metadata for resources
- 31. Troubleshooting: Identifying and resolving cluster issues
- 32. Debugging: Identifying and resolving pod issues
- Generate full text for each concept ready to paste into a document (approx. 150–250 words per concept).
- Produce YAML examples for 10 core resources.
- Create a printable one-page cheatsheet.
Scheduling & workloads 11. Scheduler — assigns pods to nodes. 12. Taints & Tolerations — node-level pod placement constraints. 13. NodeSelector & NodeAffinity — node selection rules. 14. PodAffinity & PodAntiAffinity — co-location rules. 15. Resource requests & limits — CPU/memory guarantees and caps. 16. QoS classes — BestEffort/Burstable/Guaranteed. 17. Horizontal Pod Autoscaler (HPA) — scale pods by metrics. 18. Vertical Pod Autoscaler (VPA) — adjust pod resource requests. 19. Custom Resources & Operators — extend API and manage apps. 20. InitContainers — setup containers that run before app containers.
