Taints and Tolerations

  • Taints are set of Nodes

  • Tolerations are set of POds

  • Taint a Node:

kubectl taint nodes node-name key=value:taint-effect
  • taint-effect is what happens to pod if they don't tolerate taint

  • taint-effects:

    • NoSchedule

    • PreferNoSchedule

    • NoExecute

  • Toleartion for pod:

kubectl taint node node1 blue=app:NoSchedule
  • So toleration can be added using

    - key: "blue"
      operator: "Equal"
      value: "app"
      effect: "NoSchedule"
