If Service Type is ClusterIP set spec.addresses.value into ClusterIP

[akhenakh]

When creating a GW using ClusterIP:

apiVersion: gateway.envoyproxy.io/v1alpha1
kind: EnvoyProxy
metadata:
  name: proxy-config-internal
  namespace: envoy-gateway-system
spec:
  provider:
    type: Kubernetes
    kubernetes:
      envoyService:
        type: ClusterIP

There is no way to set the IP address to be used, if we use spec.adresses it will set the externalIPs not the clusterIP:

apiVersion: gateway.networking.k8s.io/v1
kind: Gateway
metadata:
  name: eg-internal
  namespace: envoy-gateway-system
spec:
  addresses:
    - type: IPAddress
      value: 10.43.146.30

NAME          CLASS         ADDRESS        PROGRAMMED   AGE
eg-internal   eg-internal   10.43.146.30   True         11m

But is in fact this will produce:

spec:
  clusterIP: 10.43.65.18
  clusterIPs:
  - 10.43.65.18
  externalIPs:
  - 10.43.146.30
  internalTrafficPolicy: Cluster

In a ClusterIP case, setting the clusterIP with spec.addresses.value would probably be more useful.

we should be setting the service ClusterIP when service type is ClusterIP

[akhenakh]

You mean as a fix you won't set externalIPs anymore when it's a clusterIP, but what about a way to let the end user set the clusterIP?

same as

apiVersion: v1
kind: Service
spec:
  clusterIP: 10.96.0.10
  type: ClusterIP

I think I got what you are saying

[arkodg]

the fix here is to set gateway.spec.addresses to service.spec.clusterIPs
we should probably not set externalIPs here, unless there is a good reason to do so

Hey, is this up for grabs? I'd love to take a shot at it.:)

Anyone working on that one?

@LZiHaN are you still working on this?

sorry, I don't have bandwidth to continue working on this. perhaps someone else colud give it a try.

[zirain]

I'd like to unsign you first.

I'm interested in this. Can it be assigned to me?
