Description Etienne Simard 2021-08-26 16:56:22 UTC

Opening so we can backport to 4.8

+++ This bug was initially created as a clone of Bug #1990206 +++

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.

--- Additional comment from Etienne Simard on 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 1 Etienne Simard 2021-09-16 16:35:50 UTC

This BZ was meant to be a placeholder for a backport.

It was re-opened with the cherry-pick robot (see https://bugzilla.redhat.com/show_bug.cgi?id=2002349)
