In various AWS region m5.large instances are no longer available and thus can't be provisioned. Since OpenShift Container Platform - Installer for AWS has m5.large hard-coded for the bootstrap instance the installation are currently failing and are not able to process.
This is causing massive project impact as all other instance types required for the OpenShift Container Platform - Cluster are available.
It's therefore required to have a way to either specify the instance type for the bootstrap Node or take the same instance type as defined for either Control-Plane or Worker Nodes.
This is urgent as customers are not able to deploy OpenShift Container Platform 4 at this moment due to this issue.
There is a temporary shortage of instances available in specific availability zones.
The workaround is to explicitly specify the availability zones to use for the masters so that the first availability zone is one where there are m5.large instances available.
