Runs lukas2511/dehydrated with kappataumu/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 \
ingram/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 \
ingram/dehydrated-cloudflare-cron
Then start container, which will run update script once at start and once daily after that:
docker start dehydrated
