fix: update kubelet log path for containerd support#864
Conversation
Update kubernetes_logging.yml to use the standard kubelet log path /var/log/pods/*/*/*.log instead of Docker-specific path. This change: - Makes log rotation compatible with containerd and other container runtimes - Uses the standard Kubernetes pod log location - Maintains daily log rotation with 2 backups (3 days total retention) - Enables proper log lifecycle management by kubelet - Improves integration with log collection tools like Loki and Promtail The logrotate configuration: - Rotates logs daily - Keeps 2 rotated backups (maxage: 1 day) - Uses copytruncate for safe rotation without process interruption - Skips if directory doesn't exist yet (missingok flag) Tested on: Kubernetes v1.29.10 with containerd v1.7.22 All 3 nodes (kubenode1, kubenode2, kubenode3) successfully updated.

Modern Kubernetes clusters increasingly use containerd instead of Docker. The current configuration is Docker-specific and doesn't work reliably with containerd. The new path:

Files Changed
ansible/kubernetes_logging.yml- Single file, minimal changeNote: The
/var/log/pods/directory will be created by kubelet when it starts using this path. Logrotate hasmissingokflag so it won't fail if the directory doesn't exist initially.
