Thanks [~adoroszlai] for proposing the above changes, here is RANGER-3746 which addressed docker image size issues and has a much reduced memory footprint along with other optimizations. thanks.

> Docker image size is affected by content from each layer.  Thus, build steps like the following inflate image size:
> {code}
> COPY tarball
> RUN extract tarball
> {code}
> {code}
> COPY contents dir/
> RUN chmod/chown ... dir
> {code}
> These can be improved by:
> - using {{ADD}}, which can extract tarball, or pre-extracting the tarball locally
> - specifying chmod and chown for {{COPY}}
