tigerquoll opened a new pull request #1501: Metron-2246 rpm-docker - minimise use of bind mounts due to performance URL: https://github.com/apache/metron/pull/1501 ## Contributor Comments Docker bind shared folders have a reputation as being fairly slow and inefficient on Docker for Mac. This project restructures the rpm-docker project to stop docker bind folders from being used by the RPM process for input and scratch pad use. Docker bind folders are still used for output of the constructed RPMs. This PR restructures the rpm-docker project to use a three-stage docker build process. The first docker file is a template with the RPM building tools installed, that will be cached by docker once it is build. The second phase of the docker build process involves constructing a new docker image based on the 1st phase docker image plus the Metron jars. The third phase involves running the second phase docker image which will process the Metron Jars and place the packaged rpms into the appropriate folders in the project directory. ## Performance improvement. On my 2019 MBP, the following performance improvement were obtained: Unmodified rpm-docker project: ``` mvn package -DskipTests -T 2C -P HDP-2.5.0.0,mpack cd metron-deployment/ time mvn clean package -Pbuild-rpms -T 2C [INFO] ------------------------------------------------------------------------ [INFO] Reactor Summary: [INFO] [INFO] metron-deployment 0.7.2 ............................
