Worklaods Configurations for RWN

Protecting running applications on RWN: Use Pod tolerations to mitigate the effects on Pods running on RWN after the control plane sets node.kubernetes.io/unreachable taint to NoExecute when it cannot reach a node and the pod-eviction-timeout has expired.

spec:
    ...
    tolerations:
        - key: "node.kubernetes.io/unreachable"
          operator: "Exists"
          effect: "NoExecute"
        - key: "node.kubernetes.io/not-ready"
          operator: "Exists"
          effect: "NoExecute"
        - key: "node.kubernetes.io/unschedulable"
          operator: "Exists"
          effect: "NoExecute"
    ...
  

A more aggressive toleration is as follows:

spec:
    ...
    tolerations:
        - operator: "Exists"
