Looking to use Apache Flink in production? Try VMware Tanzu Application Catalog, the commercial edition of the Bitnami catalog.
Starting December 10th 2024, only the latest stable branch of any container will receive updates in the free Bitnami catalog. To access up-to-date releases for all upstream-supported branches, consider upgrading to Bitnami Premium. Previous versions already released will not be deleted. They are still available to pull from DockerHub.
Please check the Bitnami Premium page in our partner Arrow Electronics for more information.

You can see the equivalence between the different tags by taking a look at the tags-info.yaml
file present in the branch folder, i.e bitnami/ASSET/BRANCH/DISTRO/tags-info.yaml
.

The recommended way to get the Bitnami flink Docker Image is to pull the prebuilt image from the Docker Hub Registry.
docker pull bitnami/flink:latest
To use a specific version, you can pull a versioned tag. You can view the list of available versions in the Docker Hub Registry.
docker pull bitnami/flink:[TAG]
If you wish, you can also build the image yourself by cloning the repository, changing to the directory containing the Dockerfile and executing the docker build
command. Remember to replace the APP
, VERSION
and OPERATING-SYSTEM
path placeholders in the example command below with the correct values.
git clone https://github.com/bitnami/containers.git
cd bitnami/APP/VERSION/OPERATING-SYSTEM
docker build -t bitnami/APP:latest .
Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.

. The default endpoint runs a Flink JobManager instance (jobmanager mode), while you can use the environment variable FLINK_MODE for run the image in a different mode:
Also, you can use the help
Flink Mode in order to obtain an updated list of modes to run of different components instances
docker run --rm -e FLINK_MODE=help --name flink bitnami/flink:latest
$ Usage: FLINK_MODE=(jobmanager|standalone-job|taskmanager|history-server)
By default, the Apache Flink Packaged by Bitnami image will run in jobmanager mode.
Also, by default, Apache Flink Packaged by Bitnami image adopts jemalloc as default memory allocator. This behavior can be disabled by setting the 'DISABLE_JEMALLOC' environment variable to 'true'.
