⁠www-ssl-letsencrypt

Version of my www-ssl container which automatically makes certificates using the Let's Encrypt CA and the ACME protocol.

All you need to do is set the DOMAIN and your administrator EMAIL (used for renewal warnings) using an environment variable, and then link in the resource you want it to serve as the backend alias (the target container must serve on port 80)::

image: andrewgodwin/www-ssl-letsencrypt
environment:
    DOMAIN: www.aeracode.org
    EMAIL: [email protected]
links:
    - aeracode-varnish:backend
ports:
    - 80:80
    - 443:443

The domain must resolve to point at the container on ports 80 and 443; the SSL container will complete the ACME challenge automatically and install the certificates, and auto-renew the certs every week to make sure they're kept up to date.

HTTP traffic will just be forwarded through to the backend unaffected.
