Docker Labels for Latest Major Versions

Is your feature request related to a problem? Please describe.

Implement major version tagging in Data Prepper per opensearch-project/opensearch-build#1621. More details are in that issue.

Once completed, users can run the following command to get the latest version within a major-version series.

docker pull opensearchproject/data-prepper:1

Out of scope

This does not include major/minor. If requested, this could be added in future versions.

The opensearch-build project has a generic Jenkins job which can copy a Docker image from one location to another. After performing the promotion build which will create a Docker image with the specific version label (say 1.5.0), the opensearch-build team will run the job above to copy the Docker image. That job will copy from the specific version label (e.g. 1.5.0) to the desired major version label (e.g. 1). This will be a manual step and will not be implemented in the Data Prepper Jenkinsfile.

This will be completed along with the release process.
