letsencrypt.sh-ovh

This script is intented to be used as hook for official letsencrypt certbot.

It's is inspired (a lot) from the work of https://ungeek.fr/letsencrypt-api-ovh/ who made it for dehydrated acme client.

Requirements

• Python
• Curl
• OVH Python library pip install ovh

Setup

1. Get OVH API keys

See https://api.ovh.com/createToken/ and fill in ovh.conf with data received (copy it from demo sample before).

You can leave the configuration file in the repository directory. But for using the hook scripts outside of the letsencrypt.sh-ovh directory, it could be better to move it to one of the the following locations:

• /etc/ovh.conf
• ~/.ovh.conf

Usage

Check certbot docs for it but you will need at least the following params:

--preferred-challenge dns --manual --manual-auth-hook ./manual-auth-hook.py --manual-cleanup-hook ./manual-cleanup-hook.py

Potential issues

Dns updates can take up to 24 hours to propagate. Actually, in most cases it will take a few seconds.
By default, the auth hook waits 10 seconds for the dns update. If this time is insufficient, you can increase it by setting a CERTBOT_OVH_SLEEPTIME environment variable with the intended delay:

export CERTBOT_OVH_SLEEPTIME=30
