Kubernetes学习笔记（十）：Taints and Tolerations

• Taints - Node :

kubectl taint nodes node-name key=value:taint-effect

taint-effect : NoSchedule | PreferNoSchedule | NoExecute

NoExecute : 新Pod不会部署，已存在的节点也会终止

• Tolerations - Pods :

pod-definition.yml

spec:
  tolerations:
  - key: app
    operator: Equal
    value: blue
    effect: NoSchedule

kubectl describe node kubemaster | grep Taint : 查看master node的Taint

kubectl taint node node-name key=value:NoSchedule- : 清除taint
