I follow the tutorial for building kubeflow on GCP.

At the last step, I got stuck at "Check the permissions for your training component".

After setting these secretName and secretMountPath.

kustomize edit add configmap mnist-map-training --from-literal=secretName=user-gcp-sa
kustomize edit add configmap mnist-map-training --from-literal=secretMountPath=/var/secrets

and run

kustomize build . |kubectl apply -f -

I got the error:

Error: field specified in var '{GOOGLE_APPLICATION_CREDENTIALS ~G_v1_ConfigMap {data.GOOGLE_APPLICATION_CREDENTIALS}}' not found in corresponding resource error: no objects passed to apply

I cannot find my GOOGLE_APPLICATION_CREDENTIALS at /var/secrets in my local machine, but I think kubeflow will automatic create for me based on this document.

Or maybe because I use "Authenticating with username and password" for authenticating kubeflow?
