BackendConfig timeoutSec doesn't seem to work with GCE Ingress

[ConradIrwin]

I created a backendconfig object like this:

  apiVersion: cloud.google.com/v1beta1
  kind: BackendConfig
  metadata:
    name: mediaproxy-backend-config
  spec:
    timeoutSec: 120
    cdn:
      enabled: true
      cachePolicy:
        includeHost: true
        includeProtocol: true
        includeQueryString: true

and attached it to the service like this:

apiVersion: v1
kind: Service
metadata:
  name: mediaproxy
  labels:
    name: mediaproxy
  annotations:
    beta.cloud.google.com/backend-config: '{"ports": {"8080":"mediaproxy-backend-config"}}'
spec:
  type: NodePort
  ports:
    - port: 8080
  selector:
    name: mediaproxy

and created an ingress like this:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: mediaproxy
  labels:
    name: mediaproxy
  annotations:
    kubernetes.io/tls-acme: "true"
spec:
  tls:
    - secretName: ingress-mediaproxy-lego
      hosts:
      - {{ .Domains.Mediaproxy }}
  backend:
    serviceName: mediaproxy
    servicePort: 8080

The load balancer created in my google cloud project correctly had the CDN enabled, but the timeout was still displayed as 30 seconds in the Google Cloud Console. I have since edited the timeout using the Google Cloud Console and it seems to stick with the value of 120 that I set manually.

@ConradIrwin Are you running a GKE cluster with version at or above 1.11.3-gke.18?

[ConradIrwin]

I'm running the default for Google Cloud, which seems to currently be v1.10.9-gke.5

[MrHohn]

As per https://cloud.google.com/kubernetes-engine/docs/how-to/configure-backend-service, you will need to upgrade GKE master version to >= 1.11.3-gke.18 to be able to configure timeoutSec via BackendConfig.

[ConradIrwin]

Ah, thank you, and sorry for the confusion.

For some reason this is not working as of GKE 1.21 either.

[sandrotanner]

I am running GKE 1.24 and I too cannot get it to apply for some reason. I even deleted the ingress and created it again with no luck.
Are @ernani ernani and I doing something wrong or is it not working anymore?

Here is what I am doing:

Backendconfig:

apiVersion: cloud.google.com/v1
kind: BackendConfig
metadata:
  name: backendconfig-websocket-timeout
spec:
  timeoutSec: 7200

ingress:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: REDACTED
  annotations:
    [...]
    cloud.google.com/backend-config: '{"default": "backendconfig-websocket-timeout"}'
    kubernetes.io/ingress.class: "gce"
   [...]

[sandrotanner]

I made an error, now it works. see #1803

Just out of nowhere it started working too here, but, it takes some minutes to reflect the changes, which is an acceptable thing.
