    --env-file letsencrypt.env \
    letsencrypt \
    dehydrated \
        --cron --domain letsencrypt.willfarrell.ca \

Deploy

See https://github.com/willfarrell/docker-nginx for full example

# private
docker run \
    --volumes-from nginx_nginx_1 \
    --env-file letsencrypt.env \
    willfarrell/letsencrypt \
    dehydrated \
        --cron --domain letsencrypt.willfarrell.ca \
        --out /etc/ssl \
        --hook dehydrated-dns \
        --challenge dns-01

# public
docker run -d \
    --volumes-from nginx_nginx_1 \
    --env-file letsencrypt.env \
    willfarrell/letsencrypt \
    dehydrated \
        --cron --domain letsencrypt.willfarrell.ca \
        --out /etc/ssl \
        --challenge http-01

Note: certbot/make_letsencrypt_cert is an alternate method that one could use with the certbot docker image. However dns-01 is not supported.
