Kubernetes删除node

删除一个节点前，先驱赶掉上面的pod

kubectl drain node-06 --delete-local-data --force --ignore-daemonsets

此时节点上面的pod开始迁移

检查节点状态，被标记为不可调度节点

[root@node-01 ~]# kubectl get nodes
NAME      STATUS                     ROLES    AGE     VERSION
node-01   Ready                      master   2d19h   v1.14.1
node-02   Ready                      master   2d18h   v1.14.1
node-03   Ready                      master   2d18h   v1.14.1
node-04   Ready                      <none>   2d18h   v1.14.1
node-05   Ready                      <none>   2d18h   v1.14.1
node-06   Ready,SchedulingDisabled   <none>   2d18h   v1.14.1

最后删除节点

[root@node-01 ~]# kubectl delete node node-06
node "node-06” deleted

[root@node-01 ~]# kubectl get nodes
NAME      STATUS   ROLES    AGE     VERSION
node-01   Ready    master   2d19h   v1.14.1
node-02   Ready    master   2d19h   v1.14.1
node-03   Ready    master   2d19h   v1.14.1
node-04   Ready    <none>   2d18h   v1.14.1
node-05   Ready    <none>   2d18h   v1.14.1

连到node-06服务器卸载kubernetes数据

kubeadm reset
