My own shitty (yet better than anything else I've tried) version of a dns-01 hook and deploy script for dehydrated letsencrypt client
To use with: dehydrated.
Set HOOK_CHAIN="yes" in dehydrated/config.
Your account's CloudFlare email and API key are expected to be in the environment, so make sure to:
$ export CF_EMAIL='user@example.com'
$ export CF_KEY='K9uX2HyUjeWg5AhAb'
Alternatively, these statements can be placed in dehydrated/config, which is automatically sourced by dehydrated on startup:
echo "export CF_EMAIL='user@example.com'" >> config
echo "export CF_KEY='K9uX2HyUjeWg5AhAb'" >> config
Cloudflare API key tutorial is here.
Is completly optional, edit it for your use case or make sure to delete it if you don't!
