I am able to create the datalab instance via Cloudshell with datalab create datalab-instance-name shell command but unable to find a way to create it via GCP console.
Is there any specific reason for not allowing to create datalab via GCP console?
I have reviewed the Cloud Datalab Documentation and I could confirmed that the only way to create a datalab instance is via the datalab create command. This is the only available option regardless the location/region where the datalab instance is being generated.
