  ### Show all mapped ports

  You can find out all the ports mapped by not specifying a `PRIVATE_PORT`, or
  just a specific mapping:

  ```bash
  $ docker ps

  CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                                            NAMES
