Review this list of the required Amazon Web Service (AWS) service quotas that are required to run an Red Hat OpenShift Service on AWS cluster.
The table below describes the AWS service quotas and levels required to create and run an Red Hat OpenShift Service on AWS cluster.
The AWS SDK allows ROSA to check quotas, but the AWS SDK calculation does not account for your existing usage. Therefore, it is possible that the quota check can pass in the AWS SDK yet the cluster creation can fail. To fix this issue, increase your quota. |
If you need to modify or increase a specific quota, see Amazon’s documentation on requesting a quota increase. Large quota requests are submitted to Amazon Support for review, and take some time to be approved. If your quota request is urgent, contact AWS Support.
For On-Demand Standard (A, C, D, H, I, M, R, T, Z) Amazon EC2 instances, creating a ROSA cluster requires 100 vCPUs or greater. To request for your quota to be increased, open the Service Quotas console within the AWS console. |
