Service quota errors

One of the most common preflight errors users see when trying to run their Red Hat® OpenShift® Service on AWS (ROSA) cluster is related to service quotas. Some examples of these are:

error creating VPC: VpcLimitExceeded: The maximum number of VPCs has been reached.

and

AWS Error Message: Account ##### exceeded the container limit, S3

These errors indicate that you do not have the required number of service quotas to run a cluster. To create and run a ROSA cluster, you’ll need these AWS service quotas. You can run list-service-quotasin the AWS CLI to see your applied quotas and list-aws-default-service-quotasto see the default values for quotas given to all AWS accounts. 

You can request service quotas via your AWS Console by following these directions. Be aware that these requests will result in increased charges to your AWS account. See the Cluster Cost Optimization resource for guidance on how to optimize the EC2 usage on your cluster.
