Attila Doroszlai commented on RANGER-5158:
------------------------------------------
Thanks a lot [~abhi_2110] for testing this. When building the {{ranger}} image
on top if this, we will need to remove the custom definition of JAVA_HOME from
{{dev-support/ranger-docker/Dockerfile.ranger}}:
{code}
ENV
JAVA_HOME=/usr/lib/jvm/java-1.${RANGER_ADMIN_JAVA_VERSION}.0-openjdk-${TARGETARCH}
{code}
since JAVA_HOME comes from the base image of {{ranger-base}}:
{code}
$ docker run -it --rm eclipse-temurin:8-jdk-jammy bash -c 'echo $JAVA_HOME'
/opt/java/openjdk
{code}

> Key: RANGER-5158
> URL: https://issues.apache.org/jira/browse/RANGER-5158
> Project: Ranger
> Issue Type: Sub-task
> Components: docker
> Reporter: Attila Doroszlai
> Assignee: Attila Doroszlai
> Priority: Major
>
> {{ranger-base}} image is used as base image for various Ranger components.
> It can be built and published independently of Ranger, since it only includes
> runtime dependencies, nothing specific to Ranger's version.
> Proposed changes:
> - create separate repository for the base image definition
> - build and publish the image using GitHub workflow
> - include only one version of Java, but publish image in different flavors
> for different Java versions as necessary
> - build for multiple platforms (amd64, arm64)
> - publish both to Docker Hub and GitHub Container Registry
> Benefits:
> - reduced image size
> - reduced build time for derived images
> - improved usability for developers and CI
