Do i need any specific configuration for websockets ?

[stecullum]

Can someone provide the simplest sample of connecting to a websocket server and setting the loadbalancer policy to "leastConnected" ( https://gateway.envoyproxy.io/docs/api/extension_types/#loadbalancer )

I have read the documentation and the only reference to websockets is here https://gateway.envoyproxy.io/docs/api/extension_types/#appprotocoltype which needs a backendRef etc

I have seen documentation thats says use annotations and other threads implied its built in

apiVersion: gateway.networking.k8s.io/v1beta1
kind: HTTPRoute
metadata:
  name: websockets
  annotations:
    gateway.envoyproxy.io/ws: "true"  # Enable WebSocket upgrades

do i need to do something like this

...
     filters:  # Add any additional filters if required
        - type: RequestHeaderModifier
          requestHeaderModifier:
            add:
              - name: "Connection"
                value: "Upgrade"
              - name: "Upgrade"
                value: "websocket"

Im just very confused as what is needed and would appreciate a simple manifest that highlights things clearly ..

Thanks

websockets is enabled by default, you dont need any extra config
Envoy Gateway (or Envoy) doesnt support LeastConn (L4), in EG default is set to LeastRequest(L7) by default

Hi and thanks for the reply ...

Im a little confused about your comments about the load balancer types

Envoy Gateway (or Envoy) doesnt support LeastConn (L4), in EG default is set to LeastRequest(L7) by default

Here you say LeastRequest is the default.. Do you have any example that can help me get started that shows how for example i would swap to RoundRobin etc.

Thanks again for any help.
