NGINX and Certbot example with CloudFlare API in Docker

Sample config files to demonstrate seup that creates and updates free SSL certificates from Let's Encrypt given that the domains are maintained at CloudFlare service.

How it works

Certbot verifies domains ownership by accessing CloudFlare API that adds temporary TXT DNS records. To enable it You must provide your CloudFlare API token. More details in documentation for dns-cloudflare Certbot plugin.

Certbot saves created certificates in Docker volume certbot_etc. Pay attention to output of the certbot run - it mentions path to the created certificates.
