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
  • LETSENCRYPT_WILDCARD: true or false, indicating whether the SSL certificate should be for all subdomains of DUCKDNS_DOMAIN (i.e. *.test.duckdns.org), or just the main domain (i.e. test.duckdns.org)

Note: The format of DUCKDNS_DOMAIN should be the same regardless of the value of LETSENCRYPT_WILDCARD.

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
