ASF GitHub Bot updated FLINK-34439: ----------------------------------- Labels: pull-request-available (was: ) > Move chown operations to COPY commands in Dockerfile > ---------------------------------------------------- > > Key: FLINK-34439 > URL: https://issues.apache.org/jira/browse/FLINK-34439 > Project: Flink > Issue Type: Improvement > Components: Kubernetes Operator > Reporter: Mate Czagany > Assignee: Mate Czagany > Priority: Minor > Labels: pull-request-available > > We can lower the size of the output operator container image if we don't run > 'chown' commands in seperate RUN commands inside the Dockerfile, but instead > use the '--chown' argument of the COPY command. > Using 'RUN chown...' will copy all the files affected with their whole size > to a new layer, duplicating the previous files from the COPY command. > Example: > {code:java} > $ docker image history ghcr.io/apache/flink-kubernetes-operator:ccb10b8 > ... > <missing> 3 months ago RUN /bin/sh -c chown -R flink:flink $FLINK... > 116MB buildkit.dockerfile.v0 > ... {code} > This would mean a 20% reduction in image size. -- This message was sent by Atlassian Jira (v8.20.10#820010)
