Getting error while kubeflow deployment in gke

I have followed this doc to deploy kubeflow on gke

Error:404 page not found

when Accessing Central dashboard

Try to deploy multiple times but still getting same error

I'm new to kubernets

As per this official doc, try below troubleshooting steps to resolve your error :

This section provides troubleshooting information for 404s, page not found, being return by the central dashboard which is served at

https://${KUBEFLOW_FQDN}/

KUBEFLOW_FQDN is your project’s OAuth web app URI domain name <name>.endpoints.<project>.cloud.goog

We can confirm that the Ambassador reverse proxy is functioning properly by running the following command because we were able to sign in.

 kubectl -n ${NAMESPACE} get pods -l service=envoy
    NAME                     READY     STATUS    RESTARTS   AGE
   envoy-76774f8d5c-lx9bd   2/2       Running   2          4m
   envoy-76774f8d5c-ngjnr   2/2       Running   2          4m
   envoy-76774f8d5c-sg555   2/2       Running   2          4m

Now try to Attempt different administrations to check whether they're open for instance

   https://${KUBEFLOW_FQDN}/whoami
   https://${KUBEFLOW_FQDN}/tfjobs/ui
   https://${KUBEFLOW_FQDN}/hub

We know that the issue is specific to the central dashboard and not ingress if other services are accessible.

Now check that the central dashboard is running

kubectl get pods -l app=centraldashboard
NAME                                READY     STATUS    RESTARTS   AGE
centraldashboard-6665fc46cb-592br   1/1       Running   0          7h

Check that an Ambassador route is properly defined or not

kubectl get service centraldashboard -o jsonpath='{.metadata.annotations.getambassador\.io/config}'

apiVersion: ambassador/v0
  kind:  Mapping
  name: centralui-mapping
  prefix: /
  rewrite: /
  service: centraldashboard.kubeflow

,

Take a look at the logs of Envoy for blunders. Check to see if there are any errors like these that indicate a problem parsing the route. In the event that you are utilizing the new Stackdriver Kubernetes observing you can utilize the accompanying channel in the stackdriver console

 resource.type="k8s_container"
 resource.labels.location=${ZONE}
 resource.labels.cluster_name=${CLUSTER}
 metadata.userLabels.service="ambassador"
"could not parse YAML"
