This is the default admin container for Bottlerocket. The admin container has an SSH server that lets you log in as ec2-user using your EC2-registered SSH key. It runs outside of Bottlerocket's container orchestrator in a separate instance of containerd.
The admin container is disabled by default in Bottlerocket. For more information about how the admin container fits into the Bottlerocket operating system, please see the Bottlerocket documentation.
You'll need Docker 17.06.2 or later, for multi-stage build support.
Then run make!
