k8s部署

本文介绍使用 k8s 来部署 Apache ShenYu 网关。

目录

一. 使用 h2 作为数据库

  1. 1. 创建 nameSpace和 configMap
  2. 2. 部署 shenyu-admin
  3. 3. 部署 shenyu-bootstrap

二. 使用 mysql 作为数据库

  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
