----------------------------------------

             Summary: Setup versioned branches in flink-docker
                 Key: FLINK-17439
                 URL: https://issues.apache.org/jira/browse/FLINK-17439
             Project: Flink
          Issue Type: Improvement
          Components: Dockerfiles
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler


Following the discussion on the [ML|http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/DISCUSS-Move-docker-development-into-versioned-branches-tt40646.html], introduce dedicated branches for each version.

This also implies simplifications to the testing scripts (no longer have to differentiate between running one vs. all images), updating the README.md in the master branch to reflect the changes to the dev&release process, and removal of the generated Dockerfiles in the dev branches (unnecessary overhead, generate them in CI instead).
