le-godaddy-dns is a Let's encrypt module, designed to be used as a hook with dehydrated for DNS-based validation against Godaddy DNS.

To use this module you will need the following:

• curl
• python3
• godaddypy python3 module
• Production Godaddy API keys
• OpenSSL (or basically whatever dehydrated depends on)

Before anything else: Back up your zone-file.

You are letting a program meddle with your DNS. Bugs happen. Shit happens. Be prepared.

First you need to download all dependencies and configure letsencrypt.sh.

# get dependencies
sudo apt-get install python3 python3-pip curl
python3 -m pip install --user godaddypy

# setup a workplace
ROOTDIR=$HOME/letsencrypt
mkdir -p $ROOTDIR
cd $ROOTDIR

# get letsencrypt.sh
git clone https://github.com/lukas2511/dehydrated
# get le-godaddy-dns
git clone https://github.com/josteink/le-godaddy-dns

# configure dehydrated
cd $ROOTDIR/dehydrated
nano domains.txt

# the format for domains.txt is documented in letsencrypt.sh's repo.
# https://github.com/lukas2511/dehydrated/blob/master/docs/domains_txt.md
cat domains.txt
mydomain.com sub.mydomain.com
example.com
...

Now you need to configure le-godaddy-dns and retrieve your certs.

# configure your API keys
export GD_KEY=your_key_here
export GD_SECRET=your_secret_here

# run letsencrypt.sh in "cron" mode (-c)
# this creates CSRs, keys and everything we need automatically for us.
./dehydrated --challenge dns-01 -k $ROOTDIR/le-godaddy-dns/godaddy.py -c

You should now have your certs, and the output should tell you where they are.

You can put the last section in a script and add as a cronjob to ensure your certificates gets auto-renewed.

You can optionally inspect that they look like they should

find . -name fullchain.pem -exec openssl x509 -in '{}' -text -noout \;
find . -name fullchain.pem -exec openssl x509 -in '{}' -subject -noout \;

You may also decide to customize the deploy_certificates hook in goddady.py if you want the certificates automatically copied to another destination than the one provided by letsencrypt.sh.

This module is provided as is and comes with absolutely NO warranties and I take absolutely NO responsibility should an error resulting from using this script wipe out your DNS and get your Godaddy account terminated.

Bugs in dependant Python-modules have resulted in data-loss for the author, and while the currently published code only uses code proven to be safe at time of writing, I can make no guarantees about how things may or may not work in the future.

Testing the module on a test-domain where you can afford downtime is definitely recommended.

That said, it all works for me.
