K8S(十)——验证kubernetes集群

一、在一个节点配置资源清单

[root@sx7-22 ~]# vim nginx-ds.yaml
apiVersion: extensions/v1beta1
kind: DaemonSet
metadata:
  name: nginx-ds
spec:
  template:
    metadata:
      labels:
        app: nginx-ds
    spec:
      containers:
      - name: my-nginx
        image: harbor.od.com/public/nginx:v1.7.9
        ports:
        - containerPort: 80

二、配置和检查

[root@sx7-22 ~]# kubectl create -f nginx-ds.yaml
daemonset.extensions/nginx-ds created
[root@sx7-22 ~]# kubectl get pods
[root@sx7-22 ~]# kubectl get pods -o wide
[root@sx7-22 ~]# curl 172.7.22.2

三、验证集群是否ok

[root@sx7-22 ~]# kubectl get pods
[root@sx7-22 ~]# kubectl get cs
[root@sx7-22 ~]# kubectl get nodes
