By default the SSL certificate is generated for `DUCKDNS_DOMAIN` (optional)\n* `LETSENCRYPT_WILDCARD`: `true` or `false`, indicating whether the SSL certificate should be for subdomains *only* of `LETSENCRYPT_DOMAIN` (i.e. `*.test.duckdns.org`), or for the main domain *only* (i.e. `test.duckdns.org`) (optional, default: `false`)\n* `LETSENCRYPT_EMAIL`: Email used for certificate renewal notifications (optional)\n* `TESTING`: `true` or `false`, indicating whether a staging SSL certificate should be generated or not (optional, default: `false`)\n* `UID`: User ID to apply to Let's Encrypt files generated (optional, recommended, default: `0` - root)\n* `GID`: Group ID to apply to Let's Encrypt files generated (optional, recommended, default: `0` - root)\n\n## Notes\n\n* The `DUCKDNS_DOMAIN` should already be pointing to the server with a dynamic IP. The [aazarios/duckdns](https://gitlab.com/aazario/docker-duckdns) image can be used to automatically update the IP address.\n* The format of `DUCKDNS_DOMAIN` should be `.duckdns.org`, regardless of the value of `LETSENCRYPT_WILDCARD`.\n* To use `LETSENCRYPT_DOMAIN` feature, the following DNS records need to be created for ACME authentication (records should not be proxied):\n\n| Type | Name | Value | Condition |\n|-------|----------------------------------------|------------------------------------|-----------------------------------|\n| CNAME | `*.` | `` | `LETSENCRYPT_WILDCARD` == `true` |\n| CNAME | `` | `` | `LETSENCRYPT_WILDCARD` == `false` |\n| CNAME | `_acme-challenge.` | `_acme-challenge.` | |\n\n## Volumes\n\n* `:/etc/letsencrypt`: A named or host volume which allows SSL certificates to persist and be accessed by other containers\n\n**Note:** To use the `` host volume in another container, mount it as read-only for those containers. The `` host volume should be read-write enabled for the Letsencrypt container.\n\n\n## Usage\n\n```\ndocker run \\\n -e DUCKDNS_TOKEN=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX \\\n -e DUCKDNS_DOMAIN=test.duckdns.org \\\n -e LETSENCRYPT_WILDCARD=false \\\n -e LETSENCRYPT_EMAIL= \\\n -e ESTING=false \\\n -e UID=0 \\\n -e GID=0 \\\n -v ${PWD}/certs:/etc/letsencrypt \\\n -it aazario/duckdns-letsencrypt\n```","has_starred","hub_user","immutable_tags_settings",{"_76":11,"_77":78},"enabled","rules",[79],".*","is_automated","permissions",{"_83":17,"_84":11,"_85":11},"read","write","admin","user","storage_size",750071923,"orgData","recentTags",[92],{"_93":46,"_94":95,"_96":97,"_98":99,"_100":101,"_102":103,"_52":131,"_132":95,"_133":27,"_134":58,"_37":135,"_136":137,"_138":129,"_139":131,"_140":67,"_141":17},"content_type","creator",4051658,"digest","sha256:65b0913d67ae2aed95fcbc25d51694e83ea1009c7f50c17f8c970feba9e9f101","full_size",28113405,"id",175486977,"images",[104,121,126],{"_105":106,"_96":107,"_108":109,"_110":111,"_112":113,"_114":115,"_116":109,"_117":-5,"_118":99,"_64":67,"_119":120},"architecture","arm","sha256:40c4cd57313a0f4f747a5475ca1a484a68e5e7340bfad4643802a4ac2e5b3d6d","features","","last_pulled","2026-08-13T07:02:01.742726212Z","last_pushed","2024-08-09T11:29:59Z","os","linux","os_features","os_version","size","variant","v7",{"_105":122,"_96":123,"_108":109,"_110":124,"_112":113,"_114":115,"_116":109,"_117":-5,"_118":125,"_64":67,"_119":-5},"arm64","sha256:91024531f5e90a708a91b2804e9eb0bc714400f559f994e8a852c02214651b51","2026-08-13T07:02:01.728152009Z",30238666,{"_105":127,"_96":128,"_108":109,"_110":129,"_112":113,"_114":115,"_116":109,"_117":-5,"_118":130,"_64":67,"_119":-5},"amd64","sha256:08e0c37e3d1f9059ca0479dbf294ca5c1deeddf67d2b8adeb0e3c546ede7e68b","2026-08-13T07:02:01.747644091Z",29620396,"2024-08-09T11:29:59.236741Z","last_updater","last_updater_username","media_type","latest","repository",15745296,"tag_last_pulled","tag_last_pushed","tag_status","v2","sbxKitMetadata","isPotentialSpam","isHubSbxKitsEnabled","displaySecurityMetadata","tagAttestations","tagsHaveAttestations",[],"routes/_layout.r.$namespace.$reponame.tags",{"_32":151,"_160":161,"_147":172,"_173":11},{"_34":152,"_44":155,"_47":48,"_49":50,"_51":11,"_52":53,"_54":55,"_56":156,"_37":29,"_26":27,"_59":60,"_61":46,"_62":63,"_64":65,"_66":67,"_68":-5,"_69":63,"_70":71,"_72":11,"_73":27,"_74":157,"_80":11,"_81":159,"_86":27,"_87":88},[153,154],{"_37":38,"_39":40},{"_37":42,"_39":43},[46],[58],{"_76":11,"_77":158},[79],{"_83":17,"_84":11,"_85":11},"tags",{"_162":65,"_163":-5,"_164":-5,"_165":166},"count","next","previous","results",[167],{"_93":46,"_94":95,"_96":97,"_98":99,"_100":101,"_102":168,"_52":131,"_132":95,"_133":27,"_134":58,"_37":135,"_136":137,"_138":129,"_139":131,"_140":67,"_141":17},[169,170,171],{"_105":106,"_96":107,"_108":109,"_110":111,"_112":113,"_114":115,"_116":109,"_117":-5,"_118":99,"_64":67,"_119":120},{"_105":122,"_96":123,"_108":109,"_110":124,"_112":113,"_114":115,"_116":109,"_117":-5,"_118":125,"_64":67,"_119":-5},{"_105":127,"_96":128,"_108":109,"_110":129,"_112":113,"_114":115,"_116":109,"_117":-5,"_118":130,"_64":67,"_119":-5},[],"canDeleteTags","actionData","errors"]
