DEPRECATED

This image is officially deprecated in favor of the standard python image, and will receive no further updates after 2017-06-01 (Jun 01, 2017). Please adjust your usage accordingly.

See the discussion in docker-library/celery#1 and docker-library/celery#12 for more details.

In most cases, using this image required re-installation of application dependencies, so for most applications it ends up being much cleaner to simply install Celery in the application container, and run it via a second command.

See the way the sentry image handles running a Celery beat and workers for a concrete example of this pattern being employed (docker run -d --name sentry-cron ... sentry run cron and docker run -d --name sentry-worker-1 ... sentry run worker).
