K8s部署

本文介绍使用 K8s 来部署 Apache ShenYu 网关。

目录

示例一. 使用 h2 作为数据库

1. 创建 Namespace 和 ConfigMap2. 部署 shenyu-admin3. 部署 shenyu-bootstrap

示例二. 使用 MySQL 作为数据库

和 h2 过程类似,需要额外注意的两个地方:

1. 需要下载 mysql-connector.jar,容器启动时会执行下载命令2. 需要指定外部 MySQL 数据库配置

具体流程如下:

1. 创建 Namespace和 ConfigMap2. 部署 shenyu-admin3. 部署 shenyu-bootstrap

示例一:使用 h2 作为数据库#

1. 创建 Namespace 和 ConfigMap#

创建 Namespace 和网关用到的配置文件

  • 创建文件 shenyu-ns.yaml
