I need to test this in AWS before merge

I would argue that we commit the documentation as is letting people know that this is just an example and we don't maintain these examples. I don't think it would be any more out of date than https://github.com/cloudposse/bastion/tree/main/examples/compose. The docker-compose file in there is still set to version 2! I would be surprised if https://github.com/cloudposse/bastion/tree/main/examples/compose still works straight out of the box.
