Scheduler is not scheduling Pod for DaemonSet in Master node

Question

I want to deploy a DaemonSet for monitoring purpose. So these Pods need to be deployed in all Nodes.

A DaemonSet ensures that all (or some) Nodes run

Answer 1

Since Kubernetes 1.6, DaemonSets do not schedule on master nodes by default. In order to schedule it on master, you have to add a toleration into the Pod spec section:

tolerations:
- key: node-role.kubernetes.io/master
  effect: NoSchedule

For more details, check out the example YAML files in Kubernetss DeamonSet docu. It is also mentioned in the chapter How Daemon Pods are Scheduled.
