 <1> Specifies an AMI name where _builds_ will be run. Unlike bare metal _builds_, these container _builds_ are done directly within an ephemeral EC2 instance. This AMI must utilize ignition and contain a docker. The AMI shown in this example is used by {quay.io} for its build system.
 <2> Allows public SSH keys to be added to the build environment for remote troubleshooting access. This key, or keys, should correspond to the private key that an admin or developer will use to SSH into the build worker for debugging purposes. This key can be obtained by establishing an SSH connection to the remote host using a specific SSH key and port. For example: `$ ssh -i /path/to/ssh/key/set/in/ssh_authorized_keys -p 9999 core@localhost`.
