CloudFlare dynamic DNS and LetsEncrypt certificate Updater

chaosmagnetx/cloudflare-dynamic-certbot

https://github.com/Chaosmagnetx/cloudflare-dynamic-certbot

https://hub.docker.com/repository/docker/chaosmagnetx/cloudflare-dynamic-certbot

This docker will:

• Update every 15 min, your Dynamic DNS addresses at CloudFlare
• Using your Cloudflare authentication Issue and update (checks on startup, and daily at midnight) a LetsEncrypt HTTPS certificate

Usage

Here are some example snippets to help you get started creating a container.

docker docker create \
--name=cloudflare-dynamic-certbot \
-e email=<cloudflare email address> \
-e api=<cloudflare zone id> \
-e domain=<the.full.url.com to be updated> \
-v /path/to/certs:certs:/etc/letsencrypt \
--restart unless-stopped \
chaosmagnetx/cloudflare-dynamic-certbot

docker-compose

version: "2.1"
services:
  dcert:
    image: chaosmagnetx/cloudflare-dynamic-certbot
    restart: unless-stopped
    volumes:
      - certs:/etc/letsencrypt
    environment:
      - email=<your cloudflare login email>
      - api=<your cloudflare zone id>
      - domain=<the.full.url.com to be updated>
    container_name: dcert

Parameters

Container images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate external:internal respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

All are required

environment	api	Your cloudflare api - 'Zone ID' - can be found on the domain overview page
environment	domain	The subdomain to be updated (must be a subdomain, or www, cannot be parent domain)
volumes	/etc/letsencrypt	The shared location or volume where the certificates are saved for use by other apps
