Let's Encrypt for Duck DNS

Automatically generates Let's Encrypt certificates using a lightweight Docker container without requiring any ports to be exposed for DNS challenges.

Variables:

• DUCKDNS_TOKEN: Duck DNS Account Token
• DUCKDNS_DOMAIN: Full Duck DNS domain (e.g. test.duckdns.org)
• LETSENCRYPT_EMAIL: Email used for certificate renewal notifications

Volumes:

• <certs>:/etc/letsencrypt: A named or hosted volume which allows SSL certificates to persist and be accessed by other containers

TODO:

• Implement tests so depends_on can be used in docker-compose to prevent other containers from initialising until certificates are ready
