kubernets部署微服务电商平台

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
::         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
