ERROR: (gcloud.compute.ssh) Could not fetch resource: - The resource was not found

I'm trying to run R on Google Cloud following Google's suggested tutorial. However, I have experienced some trouble when finally creating the cluster. When creating the cluster with

elasticluster start myslurmcluster

I get the following error message

ERROR: (gcloud.compute.ssh) Could not fetch resource: - The resource 'projects/MY_PROJECT/zones/us-central1-b/instances/myslurmcluster-frontend001' was not found

I had run through previous stages of the tutorial several times with no problems but I suspect the issue might be related to the SSH keys so that I can sign in to my cluster.

Any help or advice greatly received!

  • ERROR: (gcloud.compute.ssh) Could not fetch resource:
 - The resource 'projects/MY_PROJECT/zones/us-central1-b/instances/myslurmcluster-frontend001' was not found

    The error you are getting means that when you are trying to compute SSH, your resource was not found. The reason for this case is the instance zone and gcloud default zone are different. The command line didn’t specified the instance zone. So the google cloud compute default zone was used. Obviously, The instance should not be found in the default zone. Just adding the zone option in command could solve the problem. The command format is like:

    gcloud compute --project "MY_PROJECT" ssh --zone "us-central1-b" "myslurmcluster-frontend001"

    To see what your default region and zone settings are, run the following gcloud command:

    gcloud compute project-info describe --project [PROJECT_ID]

    where [PROJECT_ID] is your own project ID.
