Kubernetes on GCE: Ingress Timeout Configuration

Question

I'm running Kubernetes on Google Compute Engine (GCE). I have an Ingress set up. Everything works perfectly except when I upload large files, the L7 HTTPS Load Balancer terminates the connection after 30 seconds. I know that I can bump this up manually in the "Backend Service", but I'm wondering if there is a way to do this from the Ingress spec. I worry that my manual tweak will get changed back to 30s later on.

The nginx ingress controller has a number of annotations that can be used to configure nginx. Does the GCE L7 Load Balancer have something similar?

Yes, it has similar annotations. Quicker then finding these is probably to configure it through the Google Cloud Console — Norbert, Jun 17 '17 at 17:06
I'm worried that if I change something manually, the changes will be overwritten next time I change my ingress spec. — Jesse Shieh, Jun 17 '17 at 17:17

This can now be configured within GKE, by using a custom resource BackendConfig.

apiVersion: cloud.google.com/v1beta1
kind: BackendConfig
metadata:
  name: my-bconfig
spec:
  timeoutSec: 60

And then configuring your Service to use this configuration with an annotation:

apiVersion: v1
kind: Service
metadata:
  name: my-service
  annotations:
    beta.cloud.google.com/backend-config: '{"ports": {"80":"my-bconfig"}}'
spec:
  ports:
  - port: 80
  .... other fields

I had ajax requests taking more than 30 secs, this worked for me. — Dalton Kim, Oct 09 '22 at 08:13

For anyone else looking for the solution to this problem, timeout and other settings (e.g. enable CDN) can only be configured manually at the moment.

Follow this kubernetes/ingress-gce issue for the latest updates on a long-term solution.
