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?
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: 60And 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 fieldsFor 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.
