-#### `image --build-dir [BUILD-DIR] --cmd [CMD]`

-The `image` subcommand builds a container image using `docker build`. By

-You can optionally pass `--image [IMAGE]` to use a custom base image. You can

-The image is build by copying the contents of your application after building

-The `CMD` is the command that Heroku will use in its container runtime to start
-your application. (e.g. `bundle exec puma -p $PORT`, `bin/server --port $PORT`).
