Let's Encrypt for Duck DNS

github originale (https://github.com/maksimstojkovic/docker-letsencrypt)

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

Environment Variables

DUCKDNS_TOKEN: Duck DNS account token (obtained from Duck DNS) (required)
DUCKDNS_DOMAIN: Full Duck DNS domain (e.g. test.duckdns.org) (required)
LETSENCRYPT_DOMAIN: Domain to generate SSL cert for. By default the SSL certificate is generated for DUCKDNS_DOMAIN (optional)
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)
LETSENCRYPT_EMAIL: Email used for certificate renewal notifications (optional)
LETSENCRYPT_CHAIN: Preferred certificate chain (e.g. ISRG Root X1, see https://letsencrypt.org/certificates for more details) (optional)
TESTING: true or false, indicating whether a staging SSL certificate should be generated or not (optional, default: false)
UID: User ID to apply to Let's Encrypt files generated (optional, recommended, default: 0 - root)
GID: Group ID to apply to Let's Encrypt files generated (optional, recommended, default: 0 - root)

Notes

The DUCKDNS_DOMAIN should already be pointing to the server with a dynamic IP. The maksimstojkovic/duckdns image can be used to automatically update the IP address.
The format of DUCKDNS_DOMAIN should be <subdomain>.duckdns.org, regardless of the value of LETSENCRYPT_WILDCARD.
To use LETSENCRYPT_DOMAIN feature, the following DNS records need to be created for ACME authentication (records should not be proxied):

Type	Name	Value	Condition
CNAME	`*.<LETSENCRYPT_DOMAIN>`	`<DUCKDNS_DOMAIN>`	`LETSENCRYPT_WILDCARD` == `true`
CNAME	`<LETSENCRYPT_DOMAIN>`	`<DUCKDNS_DOMAIN>`	`LETSENCRYPT_WILDCARD` == `false`
CNAME	`_acme-challenge.<LETSENCRYPT_DOMAIN>`	`_acme-challenge.<DUCKDNS_DOMAIN>`

Volumes

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

Note: To use the <certs> host volume in another container, mount it as read-only for those containers. The <certs> host volume should be read-write enabled for the Letsencrypt container.

Let's Encrypt for Dynu

git originale (https://github.com/aney1/certbot-domainvalidation-dynu)

This repository contains everything needed to create and renew LetsEncrypt certificates (incl. wildcard certificates) on Dynu (https://www.dynu.com/). This should work on every machine that can run docker (I'm using it on a QNAP NAS). If you already have certbot installed you can also just use the scripts in the scripts folder, without docker.

Usage with docker-compose:

You will need Docker and Docker-Compose:

https://docs.docker.com/install/ https://docs.docker.com/compose/install/

docker-compose -f <PATH_TO_FILES>/certbot/docker-compose.yml up

Cronjob to run it twice daily (like recomended by Certbot, certificates are only renewed when needed):

0 0,12 * * * python -c 'import random; import time; time.sleep(random.random() * 3600)' && docker-compose -f <PATH_TO_FILES>/certbot/docker-compose.yml up
