Runs dehydrated-io/dehydrated with SeattleDevs/letsencrypt-cloudflare-hook as a cron job to acquire and update Let’s Encrypt certificates by DNS-01 challenge using CloudFlare as the DNS provider.

For using with single domain:

docker create \
  --name=dehydrated \
  -e 'CF_EMAIL=email@domain.tld' \
  -e 'CF_KEY=API_key' \
  -e 'CF_HOST=host.domain.tld' \
  -v /path/to/certs:/dehydrated/certs \
  kjake/dehydrated-cloudflare-cron

It is possible to generate one certificate containing alternative domains without resorting to creating domains.txt in the following manner:

-e 'CF_HOST=host1.domain.tld -d host2.domain.tld -d host3.domain.tld' \

For use with multiple domains and certificates, provide a domains.txt instead, CF_HOST environment variable needs to be unset or empty for this to work:

docker create \
  --name=dehydrated \
  -e 'CF_EMAIL=email@domain.tld' \
  -e 'CF_KEY=API_key' \
  -v /path/to/domains.txt:/dehydrated/domains.txt:ro \
  -v /path/to/certs:/dehydrated/certs \
  kjake/dehydrated-cloudflare-cron

Then start container, which will run update script once at start and once daily after that:

docker start dehydrated
