Kubernetes Controllers

Deployments

Deployments allow you to manage changes to a set of replica pods. They specify a desired state for those pods, and work to achieve and maintain that state, even if it’s changed.

You can use deployments to perform rolling updates and scaling.

DaemonSets

DaemonSets allow you to run a replica pod dynamically on each node in the cluster. They will also create replicas on new nodes as they are added.
