Ingress公开TCP和UDP服务

官方文档

1. 添加 Ingress 启动参数

   - --tcp-services-configmap=$(POD_NAMESPACE)/ingress-nginx-tcp
   - --udp-services-configmap=$(POD_NAMESPACE)/ingress-nginx-udp
   

2. 创建 Configmap

   格式为：:<namespace/service name>:[PROXY]:[PROXY]

   • TCP

     cat <<EOF | kubectl apply -f -
     apiVersion: v1
     kind: ConfigMap
     metadata:
       name: ingress-nginx-tcp
       namespace: default
     data:
       9000: "default/example-go:8080"
     EOF
     

   • UDP

     cat <<EOF | kubectl apply -f -
     apiVersion: v1
     kind: ConfigMap
     metadata:
       name: ingress-nginx-udp
       namespace: default
     data:
       53: "kube-system/kube-dns:53"
     EOF
     

3. 创建完 Configmap 后即可测试访问对应端口
