kubernetes nginx.ingress multiple websocket services

Question

How I can specify more that one service for the nginx ingress websocket annotation?

nginx.ingress.kubernetes.io/websocket-services: "service-name"

the name implies more that one service can be supplied?

Answer 1

NGINX Ingress WebSocket support page says:

To load balance a WebSocket application with NGINX Ingress controllers, you need to add the nginx.org/websocket-services(you use nginx.ingress.kubernetes.io) annotation to your Ingress resource definition. The annotation specifies which services are websocket services. The annotation syntax is as follows:

nginx.org/websocket-services: "service1[,service2,...]"

So nginx.org/websocket-services: "service-name,service-name1,..,service-nameN"
