二进制部署K8s集群第13节之验证集群

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/n# @ S A ] =ginx-ds.yaml <<'eof'
apiVersion: apps/v1
kind: Dj K  8 z paemonSet
metadata:
name: my-nginp i - b + 8x
spec:
selector:
matchLabels:
app: my-nginx
templat9 A H q c o be:
metadata:
l% H & E S 7 M zabels:
app: my-nginx
spec:
containers:
- name: my-nginx
image: harbor.od.com/public/nginx:v1.7.9
ports:
- containerPort: 80
eof
kubectl create -f /root/nginx-ds.yaml

二、集检查
在hdss# p K !7-21 curl 172.7.21.2
在hdss7-22 curl 172.7.22.2

[root@hdss7-21 bin]# kubectl get cs  # 查看各组件状态
