WSO2 API manager version 4.0.0-1 Helm installation issue on Kubernetes ver 1.19 it was made for K8S version below VERS1.2

5/27/2021

I am installing API Manager on My GCP Cluster using helm chart (https://artifacthub.io/packages/helm/wso2/am-single-node) using git clone methods

after changing the three files(wso2am-gateway-ingress.yaml, wso2am-ingress.yaml and wso2am-websub-ingress.yam ) following Kubernetes website info tips on https://kubernetes.io/docs/concepts/services-networking/ingress/

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-resource-backend
spec:
  defaultBackend:
    resource:
      apiGroup: k8s.example.com
      kind: StorageBucket
      name: static-assets
  rules:
    - http:
        paths:
          - path: /icons
            pathType: ImplementationSpecific
            backend:
              resource:
                apiGroup: k8s.example.com
                kind: StorageBucket
                name: icon-assets

I use WSO2 installation instruction from https://artifacthub.io/packages/helm/wso2/am-single-node I installed helm then nginix ingress controller successfully on namespace beanworth2

w with command

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update

helm install ingress-nginx ingress-nginx/ingress-nginx

then i installed WSO2 API MANAGER​as shown below by clonning wso2 from git git clone https://github.com/wso2/kubernetes-apim.git then updating three files named wso2am-gateway-ingress.yaml, wso2am-ingress.yaml and wso2am-websub-ingress.yaml on installation directory ~/kubernetes-apim/simple/am-single/templates/am match nginx ingress controller with link https://kubernetes.io/docs/concepts/services-networking/ingress then i installed WSO2 by run the code
helm install <RELEASE_NAME> <HELM_HOME>/am-single --version 4.0.0-1 --namespace <NAMESPACE> --dependency-update --create-namespace

the code run successfully on G8S Cluster ver1.19 but when i access tthroughthe browser it ddisplayPAGE NOT FOUNG 404 NGINIX API Manager Publisher: https://ingress loadbalacer EXTERNAL IP/publisher API Manager DevPortal: https://ingress loadbalacer EXTERNAL IP/devportal it dispaly PAGE NOT FOUNG 404 NGINIX

see my files after alteration to fit with k8s version 1.19 wso2am-gateway-ingress.yaml:
