k8s/StudyNotes/ Taints & Tolerations

• Taint's added to Node

  • There is 3 taint effects, for pods with no Toleration for the taint key=value:taint-effect

    1. NoSchedule

    2. PreferNoSchedule

    3. NoExecute => After taint, kills pods on node that cant tolerate taint.

  • Add a taint to a node Node1A

    kubectl taint nodes node1A app=MyPods:NoSchedule

• Pods can have Toleration's they can tolerate the taint, and still schedule to a Tainted node.

• The Master Node, starts with taint

  kubectl describe node kubemaster | grep Taint
