When we create a Deployment, we can specify the number of replicas and then Kubernetes creates a ReplicaSet and schedules the number of replicas of the Pod on the nodes in the cluster. A DaemonSet is another controller that manages pods like Deployments, ReplicaSets, and StatefulSets. Let’s get more details about DaemonSets.

Understanding Kubernetes DaemonSet

What is a DaemonSet?

A DaemonSet is a Kubernetes resource that ensures a specified Pod runs on all nodes or a specific subset of…
