This playbook explains how to troubleshoot and prevent common Kubernetes issues across pods, nodes, and clusters. It highlights diagnosing pod-level errors like crashes and image pull failures using logs and configs, addressing node-level issues such as resource exhaustion or “NotReady” states, and resolving cluster-level problems involving control plane or etcd failures. It also covers misconfigurations in services, RBAC, and ingress. Preventive measures include monitoring, proper resource allocation, and understanding system components. The key takeaway is that effective troubleshooting depends on isolating the problem layer and using logs, metrics, and configuration validation systematically.
