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 (obtained from Duck DNS)DUCKDNS_DOMAIN: Full Duck DNS domain (e.g.test.duckdns.org)LETSENCRYPT_EMAIL: Email used for certificate renewal notifications (optional)LETSENCRYPT_WILDCARD:trueorfalse, indicating whether the SSL certificate should be for subdomains only ofDUCKDNS_DOMAIN(i.e.*.test.duckdns.org), or for the main domain only (i.e.test.duckdns.org) (default:false)TESTING:trueorfalse, indicating whether a staging SSL certificate should be generated or not (default:false)
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
Note: If a hosted volume is used, the volume should be mounted in an unused directory in another container to prevent access conflicts.
