Kubernetes删除节点

Kubernetes集群中移除Node

在master节点上执行：
kubectl drain master --delete-local-data --force --ignore-daemonsets
kubectl drain node1 --delete-local-data --force --ignore-daemonsets
kubectl drain node2 --delete-local-data --force --ignore-daemonsets

kubectl delete node master
kubectl delete node node1
kubectl delete node node2

分别再节点执行
kubeadm reset
iptables -nvL
iptables -X
iptables -F
systemctl restart docker

清除schedulingdisabled状态

kubectl get node --show-labels
kubectl patch node node1 -p'{"spec":{"unschedulable":false}}'
kubectl patch node node2 -p'{"spec":{"unschedulable":false}}'
