/remove-kind bug

  • Where did you get annotations like client-body-timeout & grpc-backend ? This controller does NOT have anything like that https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/
  • Remove all the annotations except the backend-protocol and the snippet
  • Look at the template of a new bug report and edit your issue to provide all that information
  • Write real practical step by step instruction, including a example app image url, that readers can copy/pase from and reproduce on a minikube or kind cluster

What type of GCP load balancer are you using? Can you try port forwarding to the ingress service and see if the issue persists?

@rcng6514 the comment from @strongjz is seeking info on

client --> [port-forward-to-svc-created-by-controller] --> app

Morning, tested with TCP L4 LB removed and port forwarded to ingress-controller k8s svc. We still observe the same behaviour and connections are issued a GOAWAY after 5-10 minutes.

@longwuyuan this isn't straightforward to achieve as the app contains IP that we'd need to strip from the image which will take considerable time. We'll start the process on this but will take time so was hoping to at least start the conversation on this.

@rcng6514 , thanks, Would you know if there is a chart on artifacthub.io or a image in hub.docker.com that can be used for reproduce ?
