Description Yunfei Jiang 2021-08-05 03:17:59 UTC 
there is an invalid type (m5a.10xlarge) in AWS UPI template:
https://github.com/openshift/installer/blob/master/upi/aws/cloudformation/05_cluster_master_nodes.yaml
https://github.com/openshift/installer/blob/master/upi/aws/cloudformation/06_cluster_worker_node.yaml

Version: 4.6+

> aws ec2 describe-instance-types --instance-types m5a.10xlarge
An error occurred (InvalidInstanceType) when calling the DescribeInstanceTypes operation: The following supplied instance types do not exist: [m5a.10xlarge]

Suggestions: use m5a.12xlarge instead of m5a.10xlarge.

Comment 1 Etienne Simard 2021-08-05 13:01:46 UTC 
Hello, thanks for opening this bug!

It looks like AWS removed m5a.10xlarge and the current instance that would replace it is indeed m5a.12xlarge so we do indeed need to update this.

https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeInstanceTypes.html

Since this does not affect the majority of UPI installations, I changed the severity to low (https://prow.ci.openshift.org/view/gs/origin-ci-test/logs/release-openshift-ocp-installer-e2e-aws-upi-4.9/1422910945121800192)
Comment 2 Eric Ponvelle 2021-08-09 19:28:45 UTC 
I created a PR to address that here: https://github.com/openshift/openshift-docs/pull/35359

PTAL at your earliest convenience. Thanks!
