What steps did you take and what happened:
Pulled latest master branch and installed all the pre-requisites.
Run make build-ami-rhel-8. AMI gets generated.
Launch instance and open ports for ssh. Couldn't ssh into the instance.

ssh: connect to host ec2-1234.us-east-2.compute.amazonaws.com port 22: Connection refused

What did you expect to happen:
Should be able to SSH to the instance. Looks like the ssh server is not running

This seems to be because the cloud-init on these VM's doesnt get started due to this error

Its likely happening because image builder is installing awscli via pip which brings in urllib 1.26 under "/usr/local/lib/python3.6/site-packages/" and that is conflicting with cloud-init.

Can we move to using awscliv2 since that seems to be a self contained set of binaries without python deps or is that not compatible with the capi provider for aws ?
