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
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
version: "2.1"

- certs:/etc/letsencrypt
environment:
- email=<your cloudflare login email>

- domain=<the.full.url.com to be updated>
container_name: dcert
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.
