k8s部署

    1. 和 h2 过程类似，需要注意的两个地方
    4. 1. 需要加载 mysql-connector.jar，所以需要一个文件存储的地方
    5. 2. 需要指定外部 mysql 数据库配置，通过 endpoint 来代理外部 mysql 数据库
    8. 具体流程如下：
    11. 1. 创建 nameSpace和 configMap
    12. 2. 创建 endpoint 代理外部 mysql
    13. 3. 创建 pv 存储 mysql-connector.jar
    14. 4. 部署 shenyu-admin
    15. 5. 部署 shenyu-bootstrap
    • 创建文件 shenyu-ns.yaml
