Adam Taft commented on NIFI-4057: --------------------------------- This is a good catch and will be super easy to fix. There are some other cleanup areas that might want to be considered in the same patch. I'm wondering about: - GID=50 already exists in openjdk:8 (staff). Why are we attempting to use and rename an existing group? Just create a new group and be done with it? - Consolidate the "Setup NiFi user" into a single layer. Combine any groupadd, useradd, mkdir, chown statements into a single RUN layer. - Update the deprecated MAINTAINER statement with "LABEL maintainer" > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
