k8s-ingress

生效方式

ingress 会将 配置的规则写入 启动的 nginx-ingress pod中，中间通过设置变量转发到对应的服务上面

set $namespace      "prod";
set $ingress_name   "xxx.com";
set $service_name   "";
set $service_port   "";
set $location_path  "/";

生效规则

1. 统一path，不同namespace

   会分先后顺序
   

设置session

##helm-chart部署

value.yaml 部分参数解析

controller:
  allowSnippetAnnotations: true  #是否允许用户在 Ingress 资源中使用 *‑snippet 注解来自定义 NGINX 配置
