1.3 Ingress扩容缩容

1.扩容
  01.#获取指定的ingress名下的pod 
[root@k8s-master01 ingress-nginx]# kubectl get pod –n ingress –n ingress-nginx –owide
  02.#获取所有node
#kubectl get node
  03．#node01扩容ingress 
[root@k8s-master01 ingress-nginx]# kubectl label node k8s-node01 ingress=true
node/k8s-node01 labeled
#在节点上打了标签就会自动部署
  04.#获取指定的ingress名下的pod 
[root@k8s-master01 ingress-nginx]# kubectl get pod –n ingress –n ingress-nginx –owide

2.缩容
  01.#在node02上面缩容，注意末尾 -
[root@k8s-master01 ingress-nginx]# kubectl label node k8s-master03 ingress-
node/k8s-master labeled
  02.#删除了标签，就会自动删除其节点的ingress                        
[root@k8s-master01 ingress-nginx]# kubectl get pod -n ingress-nginx -o wide
  03.#删除ingress，需要先在lb上把后端节点删除，在到k8s里删除其节点的ingress
  04.#监听
 [root@k8s-node01 ~]# ss -ntlp |grep 80
  05.#执行[root@k8s-node01 ~]# ps aux | grep nginx
  06.#执行[root@k8s-node01 ~]# netstat –lntp
