Hi Manikumar and Luke. Thanks for the questions. 1. No, the Docker inventory files and configurations will not be the same for Open Source Software (OSS) Images and Docker Official Images (DOI).
For OSS images, the Dockerfile located in docker/jvm/dockerfile is utilized. This process is integrated with the existing release pipeline as outlined in KIP-975 <https://cwiki.apache.org/confluence/display/KAFKA/KIP-975%3A+Docker+Image+for+Apache+Kafka#KIP975:DockerImageforApacheKafka-Status>, where the Kafka URL is provided as a build argument. This method allows for building, testing, and releasing OSS images dynamically. The OSS images will continue to be released under the standard release process . In contrast, the release process for DOIs requires providing the Docker Hub team with a specific directory for each version release that contains a standalone Dockerfile. These Dockerfiles are designed to be self-sufficient, hence require hardcoded values instead of relying on build arguments. To accommodate this, in our proposed approach, a new directory named docker_official_images has been created. This directory contains version-specific directories, having Dockerfiles with hardcoded configurations for each release, acting as the source of truth for DOI releases. The hardcoded dockerfiles will be created using the docker/jvm/dockerfile as a template. Thus, as part of post release we will be creating a Dockerfile that will be reviewed by the Dockerhub community and might need changes as per their review. This approach ensures that DOIs are built consistently and meet the specific requirements set by Docker Hub. 2. Yes Manikumar, transitioning the release of Docker Official Images (DOI) to a post-release activity does address the concerns about complicating the release process. Initially, we considered incorporating DOI release directly into Kafka's release workflow. However, this approach significantly increased the RMs workload due to the addition of numerous steps, complicating the process. By designating the DOI release as a post-release task, we maintain the original release process. This adjustment allows for the DOI release to be done after the main release. We have revised the KIP to reflect that DOI releases will now occur after the main release phase. Please review the updated document and provide any feedback you might have. Thanks, Krish.
