一、创建一个资源配置清单nginx容器
在hdss7-21或hdss7-22任意一个节点上创建一个资源配置清单

cat > /root/nginx-deploy.yaml <<'eof'
apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: my-nginx
spec:
  selector:
    matchLabels:
      app: my-nginx
  template:
    metadata:
      labels:
        app: my-nginx
    spec:
      containers:
      - name: my-nginx
        image: harbor.od.com/public/nginx:v1.7.9
        ports:
        - containerPort: 80
eof

[root@hdss-7-22 ~]# kubectl apply -f nginx-deploy.yaml 
daemonset.apps/my-nginx created
[root@hdss-7-22 ~]# kubectl get pod
NAME             READY   STATUS              RESTARTS   AGE
my-nginx-g86bg   0/1     ContainerCreating   0          7s
my-nginx-wx468   0/1     ContainerCreating   0          7s

二、集群检查
在hdss7-21 curl 172.7.21.2

[root@hdss-7-22 ~]# kubectl get pods -o wide
NAME             READY   STATUS    RESTARTS   AGE     IP           NODE                NOMINATED NODE   READINESS GATES
my-nginx-894jh   1/1     Running   0          3m31s   172.7.21.2   hdss7-21.host.com   <none>           <none>
my-nginx-hgctn   1/1     Running   0          3m32s   172.7.22.2   hdss7-22.host.com   <none>           <none>
[root@hdss-7-22 ~]# curl 172.7.22.2
