file in the official-images
repository.The master
branch of this repository serves as a pure publishing area for releases.
Development happens on the various dev-X
branches.
Pull requests for a specific version should be opened against the respective dev-<version>
branch. Pull requests for all versions, or for the next major Flink release, should be opened against the dev-master
branch.
The dev-master
branch is tested against nightly Flink snapshots for the next major Flink version. This allows us to develop features in tandem with Flink.
The dev-1.x
branches are tested against the latest corresponding minor Flink release, to ensure any changes we make are compatible with the currently used Flink version.
There are additional steps required when a new Flink major version (x.y.0) is released.
latest
tag, so the aliases
array in generate-stackbrew-library.sh
must be updatedWhen a new release of Flink is available, the Dockerfiles in the master
branch should be updated and a new manifest sent to the Docker Library official-images
repo.
The Dockerfiles are generated on the respective dev-<version>
branches, and copied over to the master
branch for publishing.
Updating the Dockerfiles involves the following steps:

Once the pull request has been merged (often within 1 business day), the new images will be available shortly thereafter.
For new major Flink releases, once the new image is available, the dev-x.y
branch must be created:

generate-stackbrew-library.sh
is used to generate the library manifest file required for official Docker Hub images.
When the Dockerfiles in this repo are updated, the output of this script should replace the contents of library/flink
in the Docker official-images repo via a pull request.
Note: Since this script requires the bashbrew
binary and a compatible version of Bash, the script generate-stackbrew-library-docker.sh
can be used to invoke the script in a Docker container with the necessary dependencies.
Example:
./generate-stackbrew-library-docker.sh > /path/to/official-images/library/flink
