Question

Stakeholders say both a DaemonSet and a Deployment can "run on all nodes." Which distinction should guide the choice?

Accepted Answer

Choose a DaemonSet for one Pod per node coverage; choose a Deployment for a desired replica count scheduled anywhere eligible — "All nodes" sounds the same in a meeting, but the controllers differ. DaemonSet means coverage per node; Deployment means "keep N copies alive somewhere." Pick the controller that matches the promise, not the slogan.

Answer

Deployments always pin exactly one Pod to every node; DaemonSets only manage replica counts

Answer

Either object is identical if replicas equals the node count at create time

Answer

Use a Job when you need per-node coverage because Jobs schedule with nodeName automatically
