This Dockerfile builds an image to run the Celery Flower monitoring tool for Celery
task queues. It uses the 1.0.1 development version. The image is not meant to be run stand-alone.
The container will wait for the RabbitMQ service to begin responding before it launches.
Images are tagged with the version of Flower installed. Additional tags include the build date,
for reproducing environments. e.g. jbei/flower:1.0.1 will point to the latest build that uses
Flower v1.0.1, and jbei/flower:1.0.1-20180613 will point to the image built on 13 June, 2018.
