Run Area Detector

Start the container interactively.

sudo podman run -it --rm --name=area-detector -e AD_PREFIX=13SIM1: -p 5064:5064 -v /tmp:/tmp prjemian/synapps-6.1-ad-3.7:latest

In the container's shell:

from databroker import Broker
db = Broker.named('pdf')

# Ooverride the dask-coersion code with an improved version
# that deals with the incomplete or wrong shape metadata from ophyd.
# This is proposed to be added to databroker in
# https://github.com/bluesky/databroker/pull/596/.
