Add workaround for Airflow consuming all memory in some OS'es (#29751)
Browse files Browse the repository at this point in the history
Apparently with some recent releases of some OSes where new
containerd has been released, default docker community edition
causes Airlfow to immediately consume all memory.

This happens in Breeze and Docker Compose at least.

There is a workaround described in:
ttps://github.com/moby/moby/issues/43361#issuecomment-1227617516
to use Docker Desktop instead.

The issue is tracked in containerd in this issue - proposing to
revert the change (as it impacts other applications run in docker,
not only Airlfow):

.. warning::

Some operating systems (Fedora, ArchLinux, RHEL, Rocky) have recently introduced Kernel changes that result in
Airflow in Breeze consuming 100% memory when run inside the community Docker implementation maintained
by the OS teams.

This is an issue with backwards-incompatible containerd configuration that some of Airflow dependencies
have problems with and is tracked in a few issues:

* `Moby issue <https://github.com/moby/moby/issues/43361>`_
* `Containerd issue <https://github.com/containerd/containerd/pull/7566>`_

There is no solution yet from the containerd team, but seems that installing
`Docker Desktop on Linux <https://docs.docker.com/desktop/install/linux-install/>`_ solves the problem as
stated in `This comment <https://github.com/moby/moby/issues/43361#issuecomment-1227617516>`_ and allows to
run Breeze with no problems.
