@Oliver Paul​ Every time you create cluster in GCP databricks that uses GKE and containers to spin up your clusters. it is bit different to what we have in azure and aws.

if you are facing quota issues, there is nothing to do with GKE, can you please check your GCP plan and request for quota increase and confirm with GCP team on quota issue.

if they say any limit is there on requested instance type, try to create your databricks on another region and see if you are still facing same issue
