Customers have introduced Openshift using CloudFormation in "Example 4.55. CloudFormation template for the VPC", referring to the document below.
https://access.redhat.com/documentation/en-us/openshift_container_platform/4.8/html-single/installing/index#installing-restricted-networks-aws
CloudFormation uses python3.7 with Lambda.

Is there any immediate effect? Will there be any impact when adding worker nodes?
