Description

When the signup flow was demoed today, the discovery-feed portion was failing. An undefined url was returned. I suspect this was because the FEED_DISCOVERY_URL, was not defined in the Dockerfile, despite being defined in the docker-compose.yml, and web related stuff. I added the feed discovery url to the dockerfile as a result.
