Nginx Proxy Containers

This approach lets you do a few really powerful things:

1. Give non-SSL enabled applications SSL capabilities using a proxy
2. Automate signing up and renewing LetsEncrypt certificates
3. Allow multiple containers to exist on a single host and not worry about configuring a webserver

Use docker-letsencrypt-nginx-proxy with nginx-proxy in a single docker-compose.yml. Here's what it's doing:

• The host ports 80 and 443 go into the nginx-proxy container
• The volumes certs, vhostd, and html are persistent (important for certs!)
