1.为node节点添加label标签

kubectl label nodes kube-node node=kube-node // add label

kubectl get node -a -l points=test    // list label  points=test

2.创建rc文件

apiVersion: v1

kind: ReplicationController

metadata:

name: nginx

spec:

replicas: 2 // 创建的容器副本数量

template:

  metadata:

    labels:

      run: nginx // service的selector

  spec:

    containers:

    - name: nginx-container

      image: nginx:latest

      ports:

    nodeSelector:

      node: kube-node
