30647	[FATAL] FileNotFoundError with runserver command inside Docker container	Bobby Steinbach	Tom Forbes	"**Summary**
Trying to run the development server in a container with volume-mounted source is throwing a FileNotFoundError. I've verified that the issue is consistently reproducible with Django==2.2.3 and not present in Django==2.1.4.
