As proposed in https://lists.apache.org/thread.html/e3e87f22b14262ddd56580a7ddbbeea67885cf83a832407587e5d9a4@%3Cdev.druid.apache.org%3E, I filed https://jira.apache.org/jira/browse/INFRA-18887 to setup automated dockerhub builds for our docker image based on our release tags.
This had been requested in https://github.com/apache/incubator-druid/issues/8103. Please note that those image are not be considered an official Apache distribution channel, and thus should only be considered convenience binaries. - Xavier
