> rpm-docker: minimise use of bind mounts due to performance
> ----------------------------------------------------------
>
> Key: METRON-2246
> URL: https://issues.apache.org/jira/browse/METRON-2246
> Project: Metron
> Issue Type: Improvement
> Reporter: Dale Richardson
> Priority: Minor
>
> Docker bind mounts on MacOS have a reputation for being extremely slow. The
> rpm-docker module uses bind mounts to share out the rpm-docker project
> directory to the RPM creation docker image, which then uses it as a workspace
> when creating the METRON RPMS, and means of pushing the resulting RPM's back
> to the hosting build box.
> Bind mounts remain the most convenient way of bulk file export from a docker
> image, but the processes can be sped up by building the rpm-docker image with
> the input file already included, so that any file I/O by the rpm building
> process in its workspace does not suffer a performance penalty.
