I tried this command on gcloud shell –
gcloud compute instance-groups managed create my-mig –zone us-central1-a –template my-instance-template-with-custom-image –size 1

But it is showing error – ERROR: (gcloud.compute.instance-groups.managed.create) Could not fetch resource: – Invalid value for field ‘resource.instanceTemplate’.

I have created instace template, but still it is showing error that – my-instance-template-with-custom-image’ was not found

I verified instance template name by executing this command – gcloud compute instance-groups managed list
