再ingress-nginx的官方文档中说明websocket不需要特别的配置，但需要在注解中配置以下三项

nginx.ingress.kubernetes.io/proxy-http-version: "1.1"
nginx.ingress.kubernetes.io/proxy-read-timeout: "3600"
nginx.ingress.kubernetes.io/proxy-send-timeout: "3600"

以下是一个ingress示例

apiVersion: extensions/v1beta1
	kind: Ingress
	metadata:
	 name: ingress-service
	 namespace: <YOUR_NAMESPACE>
	 annotations:
	 kubernetes.io/ingress.class: nginx
	 nginx.ingress.kubernetes.io/proxy-read-timeout: 3600
	 nginx.ingress.kubernetes.io/proxy-send-timeout: 3600
	spec:
	 rules:
	 - http:
	 paths:
	 - path: /
	 backend:
	 serviceName: client-cluster-ip-service
	 servicePort: 3000
	 # Below is the important part!
	 - path: /ws/
	 backend:
	 serviceName: server-cluster-ip-service
	 servicePort: 40510
