Is setup_remote_docker really needed?


The CircleCI2.0 documentation tells us:

To build Docker images for deployment, you must use a special setup_remote_docker key which creates a separate environment for each build for security

This job is generating Dockerfiles not the actual images. If you look at the next section of the circle.yml it should make more sense.
