error reading created Disk: %v

Error message

error reading created Disk: %v

What it means

After creating (or confirming) the disk, RenderGCE reads the disk back with Disks().Get to fetch its label fingerprint; this error wraps any failure of that read. It indicates the disk could not be fetched immediately after its creation flow.

Solutions

1. Check the wrapped error: if notFound, verify the Insert operation truly succeeded
2. Retry kops update — Get is often transiently failing right after creation
3. Verify service account has compute.disks.get permission on the project
4. Confirm project and zone in the cluster config match where the disk was created

// ensure IAM: test compute.disks.get before applying
_, err := computeService.Disks.Get(project, zone, diskName).Do()

d, err := cloud.Compute().Disks().Get(project, zone, name)
if err != nil {
  if gce.IsNotFound(err) { /* recreate or wait */ }
  return fmt.Errorf("read created disk: %w", err)
}

When it happens

Trigger: changes.Labels is non-nil and cloud.Compute().Disks().Get(project, zone, disk.Name) returns an error — typically notFound if creation silently failed, or a transient API error.

Common situations: Disk creation operation reported success but the disk is not yet visible; wrong project/zone in cloud config; transient GCP API outage; permission revoked between insert and get.
