Dynamic configuration for running nginx inside Docker

[jmarin]

Right now the API Proxy backend is hardcoded into the nginx.conf file. Investigate ways to make it configurable at runtime

I think Automated Nginx Reverse Proxy for Docker describes the problem pretty well. His solution is to use the nginx-proxy Docker image, which uses docker-gen under the hood...both of which he wrote. :) It looks straightforward, and seems to have some traction in the community. Seems worth investigating further.

@jmarin, I think you had some alternatives as well?

@hkeeler @awolfe76 Since this is not a production website that will be exposed to the public, but more a test app, I think the easiest path would be to serve the content with Node.js and call it a day. The node server would proxy requests to the underlying APIs by reading environment variables passed at runtime, as we do with other services.
Thoughts?

Per today's standup, we decided to stick with Nginx for now, and just get CORS working for grasshopper API. This work will be tracked under cfpb/grasshopper#125.

👍 Working toward that, leaving nginx.conf as is for now.

Closing. #76 didn't close this but we're in an ok place. Can re-open if needed.
