DaemonSets Commands

Run pods on every node in your cluster. Learn DaemonSets for log collectors, monitoring agents, and other node-level services that need to run everywhere.

Pro Tips

Use nodeSelector or affinity to run DaemonSet pods only on specific nodes (e.g., only worker nodes).

DaemonSets use RollingUpdate by default. Set 'maxUnavailable' to control update pace.

For critical system pods, use tolerations to run on nodes with taints (e.g., master nodes).

Common Mistakes

DaemonSets add pods as nodes join. Ensure resource requests account for this automatic scaling.

DaemonSet pods compete with other workloads for node resources. Set appropriate priority classes.
