Scripts for getting Let's Encrypt wildcard certs from cdmon.com

Let's Encrypt has a tool called certbot-auto, which you can use to obtain wildcard certificates. There is only one problem: you need to use DNS challenge, which involves creating a TXT record at runtime, which means that your DNS registrar must have an API in order for you to be able to control it programmatically.

These scripts will help you get wildcard LE certs if you have a domain at cdmon.com

Just clone and project, provide the required environment variables (make sure to read the README.md of cdmon_automator) and then run the required commands:

Tip: I have a .env file and I run export $(cat .env | xargs).

cd cdmon_le_wildcard_certs
pip3 install -r requirements.txt

certbot-auto certonly \
    --server https://acme-v02.api.letsencrypt.org/directory \
    --manual \
    --preferred-challenges dns \
    --manual-auth-hook "./auth.py" \
    --manual-cleanup-hook "./clean.py" \
    -d '*.yourdomain.tld' \
    --manual-public-ip-logging-ok

You can also use this, if you just want to test things out:

certbot-auto certonly \
    --server https://acme-staging-v02.api.letsencrypt.org/directory \
    --manual \
    --preferred-challenges dns \
    --manual-auth-hook "./auth.py" \
    --manual-cleanup-hook "./clean.py" \
    -d '*.yourdomain.tld' \
    --manual-public-ip-logging-ok \
    --dry-run
