This optimizes the Dockerfile by; - Combining RUN statements so that files are removed in the same layer as they are added. - Removing the downloaded .tar.gz of the docker-gen binary after expanding - Adding `--no-install-recommends` (but explicitly installing ca-certificates) - Replacing `ADD` with `COPY` (recommended if no unpacking is required) Also added a `.dockerignore` file to prevent the `.git` directory and README.md being added to the image. These changes reduce the size of the image with 34 MB (was 268.4 MB, now 233.9 MB), and results in less layers being produced. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
