## MYSQL主从
- __生成mysql主从环境__
```
[root@k8smaster1 kubernetes]# cd mysql/
[root@k8smaster1 mysql]# kubectl create -f .
configmap "mysql" created
service "mysql" created
service "mysql-read" created
statefulset "mysql" created
```
- __查看生成的mysql主从环境__
```
[root@k8smaster1 mysql]# kubectl get pods|grep mysql
mysql-0 2/2 Running 0 46s
mysql-1 2/2 Running 0 37s
mysql-2 2/2 Running 0 28s
```
- __测试mysql主从环境__
