Dockerfile Changelog

The Dockerfile does not strictly follow the SemVer <https://semver.org/>_ approach of Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly follows it, the Dockerfile is really a way to give users a conveniently packaged Airflow using standard container approach, so occasionally there are some changes in the building process or in the entrypoint of the image that require slight adaptation of how it is used or built.

The Changelog below describes the changes introduced in each version of the docker images released by the Airflow team.

:note: The Changelog below concerns only the convenience production images released at Airflow DockerHub <https://hub.docker.com/r/apache/airflow>_ . The images that are released there are usually built using the Dockerfile released together with Airflow. However, you are free to take latest released Dockerfile from Airflow and use it to build an image for any Airflow version from the Airflow 2 line. There is no guarantee that it will work, but if it does, then you can use latest features from that image to build images for previous Airflow versions.

Airflow 3.1.0

In Airflow 3.1.0 we changed the base images used for building the Airflow images. Previously the images
were based on "official" Python images from DockerHub, however those images sometimes lag behind the
latest security patches and their maintainers made decisions about using older setuptools and pip versions,
however we want to be able to use the latest versions of those tools to build the images. Therefore
we decided to use ``bookworm-slim`` images from Debian as the base images for Airflow images and we compile
and install the latest Python version in the image based on the official packages from the Python Software
Foundation. This change should be transparent for those who extend the images or use them "as is", however
for those who want to build custom images, there are changes to the build-args passed to the ``docker build``
command:

The PYTHON_BASE_IMAGE arg is no longer supported - the base image is always debian:bookworm-slim
