Dockerfile

FROM ubuntu:20.04

#
# Dockerfile for the 4DGB Browser Runner
# 
# This Dockerfile installs all the necessary Python3 and Javascript
# dependencies for the 4DGB Browser.
# When run, a container will import a project from whatever is mounted
# at the '/project' directory, build a release from it, then start up
# a server via gunicorn for it.
#
