Allows the automatic generation of wildcard certificates for your domain using the Aruba web API.
The reference of Aruba web API you can find here.
To use this script you need some dependencies. It uses the following elements:
✅ Certbot https://certbot.eff.org/
✅ jq
✅ python 3
☝ Verify that your system support these packages or install its. ☝
Let's assume that aruba_auth_dns.sh and aruba_cleanup_dns.sh are in this folder (/root/certbot_hooks).
Let's assume that send_mail.py is in (/root/script).
You MUST edit aruba_auth_dns.sh and change some parameters:
DEST_MAIL='your_mail@domain.tld'
API_KEY='2ec*****-****-****-****-*********dbe'
ARUBA_USER='******.webapi'
ARUBA_PSW='*************'
❗❗ Make sure the user created on Aruba has OTP disabled!
You MUST edit send_mail.py and change some parameters:
emailfrom = "your_mail@domain.tld"
username = "your_mail@domain.tld"
password = "*************"
#using TLS (comment out next two rows if use SSL)
server = smtplib.SMTP("smtp.domain.tld", 587)
server.starttls()
#using SSL (uncomment next row if use SSL)
#server = smtplib.SMTP_SSL('smtp.domain.tld', 465)
Next step is run certbot to generate your first wildcard certificate by automating the process.
certbot certonly --manual --preferred-challenges=dns --email your_mail@domain.tld \
--server https://acme-v02.api.letsencrypt.org/directory --agree-tos \
--manual-auth-hook /root/certbot_hooks/aruba_auth_dns.sh \
--manual-cleanup-hook /root/certbot_hooks/aruba_cleanup_dns.sh \
-d *.domain.tld
☝ Set your real mail to accept the registration on Let's Encrypt
❌ Is possible that the first time you can get an error because the TXT record has been added but the DNS hasn't yet been propagated.
✅ Play with sleep time (seconds) at latest row in aruba_auth_dns.sh

If you want to automatically update your certificates add this line to crontab.
