Issue  Category      Title                 Description
    1  Possible Bug  Missing Required      All commands in a Dockerfile require at least 1 argument.
                     Arguments             A line in a Dockerfile can be in any of the following formats:
                                           * * *
                                           #### `# Comment`
                                           Docker will treat any line that begins with a `#` as a comment.
                                           * * *
                                           #### `INSTRUCTION arguments`
                                           All instructions require at least 1 argument, and should be on the
                                           same line as the `INSTRUCTION`.
                                           * * *
                                           #### `RUN` continuation
                                           If a `RUN` line ends with a `\`, the next line will be treated as
                                           part of the same `RUN` arguement.
                                           * * *
                                           #### Blank or Whitespace
                                           Blank lines are allowed and will be ignored.
                                           * * *
    2  Clarity       Capitalize            For clarity and readability, all instructions in a Dockerfile
                     Dockerfile            should be uppercase.
                     Instructions          This is a convention adopted by most of the official images and
                                           greatly improves readability in long Dockerfiles.  For an example
                                           of
                                           why this makes a difference, check out the current [redis
                                           Dockerfile](https://github.com/docker-library/redis/blob/b375650fb6
                                           9b7db819e90c0033433c705b28656e/3.0/Dockerfile)
                                           and you should be able to easily see the instructions used.
    3  Possible Bug  First Command Must    The first instruction in a Dockerfile must specify the base image
                     Be FROM or ARG        using a FROM command or an ARG command to modify the FROM command.
                                           Additionally, FROM cannot appear later in a Dockerfile.
    4  Possible Bug  Invalid Line          This line is not a valid Dockerfile line.
