本文主要是介绍k8s学习(二十八) K8s部署单节点mysql-statefulset方式，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
以下步骤的前提是已部署好storageclass，可参考https://blog.csdn.net/u011943534/article/details/100887530
1、下载mysql(已经下载好)
docker pull mysql:5.7
docker save -o mysql-5.7.tar mysql:5.7
2、导入镜像
将msyql-5.7.tar拷贝至K8s镜像服务器所在的节点
docker load -i mysql-5.7.tar
docker tag mysql:5.7 172.16.10.160:80/mysql:5.7
docker push 172.16.10.160:80/mysql:5.7
3、使用 kubectl apply -f mysql-server.yaml部署

4、查看pod
5、外部使用31112端口访问
如果无需外部访问，将31112对应的service删除。
内部使用headless的service访问（ClusterIP:None的）
