Step 5: 连接到Mariadb多主集群 a. 获取Mariadb服务地址:获取Mariadb服务的Cluster IP。 `$ kubectl get service my-mariadb -n my-mariadb` b. 使用Mariadb客户端连接到集群:使用Mariadb客户端连接到Mariadb多主集群。 `$ mysql -h-uroot -ppassword` 至此,我们成功搭建了一个基于Kubernetes的Mariadb多主...

在上面的代码中,我们定义了四个环境变量 DB_HOST、DB_PORT、DB_USER、DB_PASS,分别引用了Secret对象中对应的数据库连接信息。 步骤三:应用程序中使用Kubernetes Service访问数据库 最后,在我们的应用程序中,我们可以通过Kubernetes Service来访问Mariadb数据库。我们只需使用Service的Cluster IP和暴露的端口即可连接到数...
