GKE Ingress Bad Gateway or Backend not found

[dotnetpiper]

Hi Team,

I've been using GKE and setup GKE Ingress mere to manage the path for all images which we have kept in GCR. I've created a .Net core based API which is has various path , if I expose the deployment with service as type Loadbalancer it works perfectly. Though when I utilize GKE Ingress and setup service and its backend it throws an error like Bad Gateway or sometime backend not found.

.Net core api application exposes following path when i exposed on service as loadbalancer, kindly follow below screenshot for reference: http://35.202.38.40/api/books http://35.202.38.40/api/categories

The same way we do have post api's.

Now I'm stuck when I utilize GKE ingress and setup my ingress.yaml as follows , it doesn't work and throws an error. Ingress.Yaml

`apiVersion: networking.k8s.io/v1beta1 kind: Ingress metadata: name: gke-ingress annotations:

If the class annotation is not specified it defaults to "gce".

kubernetes.io/ingress.class: "gce"    

spec:
rules:

• http: paths:
  • path: /* pathType: ImplementationSpecific backend:
    serviceName: hello-world servicePort: 80
  • path: /api/*
    backend:
    serviceName: hello-world servicePort: 80 `

NOTE: my hello-word is exposing a .Net Core API application, kindly don't get confuse with name as "hello-world" for testing.

Deployment and service Yaml

`apiVersion: apps/v1 kind: Deployment metadata: name: hello-world-deployment spec: selector: matchLabels: greeting: hello department: world replicas: 2 template: metadata: labels: greeting: hello department: world spec: containers:

• name: hello image: gcr.io/strategic-uop-322987/bookapp:631 ports:

  • containerPort: 80

    apiVersion: v1 kind: Service metadata: name: hello-world spec: type: NodePort selector: greeting: hello department: world ports:

    • protocol: TCP port: 80 targetPort: 80`

Kindly advise how to setup path based routing in GKE Ingress for .Net Core Api app.

Hi @dotnetpiper the question does not seem to be related to Kubeflow. Can you ask Cloud Support for help?
