一、Rancher使用Helm安装Ingress控制器¶

1、依次点击【应用】-【Chart】，搜索Ingress,选择【NGINX Ingress Controller】

2、选择11.0.0版本后，点击【安装】

3、创建名为ingress-nginx的新命名空间，勾选【在安装前自定义Helm选项】后，点击【下一步】

4、编辑选项这块修改镜像nginx/nginx-ingress为国内镜像registry.cn-hangzhou.aliyuncs.com/abroad_images/nginx-ingress，点击【下一步】

修改后的地方如下：

#82-83修改镜像为国内镜像
    registry: registry.cn-hangzhou.aliyuncs.com
    repository: abroad_images/nginx

#182-183修改镜像为国内镜像
  registry: registry.cn-hangzhou.aliyuncs.com
  repository: abroad_images/nginx-ingress-controller
#318行修改服务类型为NodePort
  type: NodePort

修改完整体配置如下：

6、点击【安装】

7、点击【工作负载】-【Deployment】，观察到资源已成功建立

后台查看
