 一、准备条件

1) 确保kubernetes可以访问:reg.yunwei.edu镜像库(vim /etc/hosts)
[root@cicd yml]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.254.20 reg.yunwei.edu
#192.168.253.9 reg.yunwei.edu
192.168.253.9 cicd
192.168.253.14 node1
192.168.253.11 node2
192.168.253.10 node3
2) 然后创建sock-shop的名称空间。
  kubectl create namespace sock-shop
[root@cicd yml]# kubectl get ns
NAME          STATUS    AGE
default       Active    3d
kube-public   Active    3d
kube-system   Active    3d
sock-shop     Active    3h
weave         Active    2h

  3) 需要准备镜像:

 4) 然后进入sock-shop目录下下载所需镜像到sock-shop命名空间。

[root@cicd yml]# cd /root/kubernetes/sock-shop/
[root@cicd sock-shop]# ls
complete-demo.yaml

二、部署微服务

 
编辑complete-demo.yaml后,执行
kubectl apply -f complete-demo.yaml
 
查看前端service的访问端口:
kubectl get pod -n sock-shop
kubectl get service -n sock-shop
[root@cicd sock-shop]# kubectl get pod -n sock-shop          sock-shop内pod状态
NAME                            READY     STATUS    RESTARTS   AGE

 三、登录浏览器验证(集群节点ip+端口:192.168.253.10:30001)
