k8s 污点常用操作

一、查看当前五点状态

# kubectl describe node  | grep Taints

二、设置五点禁止调度，同事进行驱赶现有pod

# kubectl taint nodes k8s-master01 key1=value1:NoExecute
# kubectl taint nodes k8s-master02 key1=value1:NoExecute
# kubectl taint nodes k8s-master03 key1=value1:NoExecute

三、取消污点

# kubectl taint nodes k8s-master01 key1=value1:NoExecute-

# kubectl taint nodes k8s-master02 key1=value1:NoExecute-

# kubectl taint nodes k8s-master03 key1=value1:NoExecute-

四、设置五点，禁止调度，不进行驱赶现有pod

# kubectl taint nodes k8s-master01 key1=value1:NoSchedule
# kubectl taint nodes k8s-master02 key1=value1:NoSchedule
# kubectl taint nodes k8s-master03 key1=value1:NoSchedule

五、取消污点

# kubectl taint nodes k8s-master01 key1=value1:NoSchedule-
# kubectl taint nodes k8s-master02 key1=value1:NoSchedule-
# kubectl taint nodes k8s-master03 key1=value1:NoSchedule-
