Daemonset in kubernetes

20 June 2023

Daemonset ensures that all the available worker nodes have a copy of a running pod defined within the DaemonSet.

As new nodes are added the pods of daemonset are added to them.

Daemonsets follow the regular scheduling rules and if the scheduling rules don’t allow pods to run on a particular node then the daemonset will respect scheduling rule and won’t assign pod to it.

Usage :

• logs collection

• node monitoring
