关于nginx:ingressnginx-tcpudp转发

ingress-nginx设置tcp/udp转发

第一步，更改ingress-nginx的deployment启动参数，增加--tcp-services-configmap和--udp-services-configmap参数，开启tcp与udp的反对

containers:- args:  - /nginx-ingress-controller  - --tcp-services-configmap=$(POD_NAMESPACE)/tcp-services  - --udp-services-configmap=$(POD_NAMESPACE)/udp-services

第二步，更改ingress-nginx的service，申明tcp和udp用的端口号

  ports:  - name: proxied-tcp    nodePort: 30090    port: 9000    protocol: TCP    targetPort: 9000  - name: proxied-udp    nodePort: 30091    port: 9001    protocol: UDP    targetPort: 9001  - name: nginx    port: 9005    protocol: TCP    targetPort: 9005   

第三步，定义configmap，格局为<ingress-controller-svc-port>:"<namespace>/<service-name>:<port>",例如上面配置的data第一行示意将default命名空间下的example-go服务的8080端口映射到ingress-controller service的9000端口，即可通过ingress-controller的service ip加9000端口拜访到example-go服务

apiVersion: v1kind: ConfigMapmetadata:  name: tcp-services  namespace: ingress-nginxdata:  9000: "default/example-go:8080"  9005: "default/nginx:80"
