This a hook for the Let's Encrypt ACME client dehydrated, that enables using DNS records on Dreamhost to respond to dns-01 challenges. Requires your Dreamhost API key being in the environment.
$ git clone https://github.com/lukas2511/dehydrated
$ cd dehydrated
$ mkdir hooks
$ git clone https://github.com/ErinMorelli/dehydrated-dreamhost-hook hooks/dreamhost
$ pip install -r hooks/dreamhost/requirements.txt
$ export DREAMHOST_API_KEY='K9uX2HyUjeWg5AhAb'
$ mkdir -p ~/.config/dehydrated
$ cp hooks/dreamhost/sample_deploy.conf ~/.config/dehydrated/deploy.conf
Open the ~/.config/dehydrated/deploy.conf file in your favorite text editor and update it for your personal needs.
Get your Dreamhost API key by logging in to your control panel, and navigating to the Web Panel API page. Make sure that the "All dns functions" option is checked before clicking on "Generate a new API Key now!".
$ ./dehydrated -c -d example.com -t dns-01 -k 'hooks/dreamhost/hook.py'
