OK, wow. Yeah, that would be a problem. Good catch! Definitely need this
then.
> Docker Image is twice as large as necessary
> -------------------------------------------
>
> Key: NIFI-4057
> URL: https://issues.apache.org/jira/browse/NIFI-4057
> Project: Apache NiFi
> Issue Type: Bug
> Components: Docker
> Affects Versions: 1.2.0, 1.3.0
> Reporter: Jordan Moore
> Priority: Minor
>
> By calling {{chown}} as a secondary {{RUN}} command, you effectively double
> the size of image by creating a Docker layer of the same size as the
> extracted binary.
> See GitHub discussion:
> https://github.com/apache/nifi/pull/1372#issuecomment-307592287
> *Expectation*
> The resultant Docker image should be no larger than the Base image + the size
> required by extracting the Nifi binaries.
