Troubleshooting containerized applications
summary
Covers concrete fixes: tune readiness and liveness probe parameters (example timeout 30s, correlate periodSeconds with failureThreshold and initialDelaySeconds), inspect containers with kubectl exec -it and copy files with kubectl cp, force redeploys by patching a label or using kubectl rollout restart (k8s 1.15), adjust imagePullPolicy or use kubectl set image, check RBAC via Role/RoleBinding and audit logs, verify storageClass differences and correct volume mount paths, and stop runaway CronJobs with suspend or backoffLimit.
