By default you can connect up to 15 clusters in a project. As with other Google Cloud quotas, the actual number of clusters you can connect may be higher or lower, depending on your platform usage. You can find out more about quotas in Working with quotas.
To view your current limit and usage:
- Go to the IAM and Admin Quotas page for your project in the Cloud Console. This displays all your project's quotas.
- Browse or filter for Service: GKE Hub.
- Select the Memberships quota to view more details.
You can also use the Quotas page to cap your usage or request a higher limit, as described in Managing your quota.
