​使用注释​​nginx.ingress.kubernetes.io/server-snippet​​可以在服务器配置块中添加自定义配置。

每个主机只能使用此注释一次。

例子1：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/server-snippet: |
        set $agentflag 0;

        if ($http_user_agent ~* "(Mobile)" ){
          set $agentflag 1;
        }

        if ( $agentflag = 1 ) {
          return 301 https://m.example.com;
        }

例子2：

​​https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/#stream-snippet​​

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/stream-snippet: |
      server {
        listen 8000;
        proxy_pass 127.0.0.1:80;
      }

例子3：
