Certbot plugin for authentication using Gandi LiveDNS
This is a plugin for Certbot that uses the Gandi LiveDNS API to allow Gandi customers to prove control of a domain name.
Usage
/!\ Certbot 1.7.0 imposed breaking changes on this plugin, make sure to remove any prefix-based configuration
-
Obtain a Gandi API token (see Gandi LiveDNS API)
-
Install the plugin using
pip install certbot-plugin-gandi
-
Create a
gandi.ini
config file with the following contents and applychmod 600 gandi.ini
on it:# live dns v5 api key dns_gandi_api_key=APIKEY # optional organization id, remove it if not used dns_gandi_sharing_id=SHARINGID
Replace
APIKEY
with your Gandi API key and ensure permissions are set to disallow access to other users. -
Run
certbot
and direct it to use the plugin for authentication and to use the config file previously created:certbot certonly --authenticator dns-gandi --dns-gandi-credentials /etc/letsencrypt/gandi/gandi.ini -d domain.com
Add additional options as required to specify an installation plugin etc.
Please note that this solution is usually not relevant if you're using Gandi's web hosting services as Gandi offers free automated certificates for all simplehosting plans having SSL in the admin interface.
Be aware that the plugin configuration must be provided by CLI, configuration for third-party plugins in cli.ini
is not supported by certbot for the moment. Please refer to #4351, #6504 and #7681 for details.
Distribution
PyPI is the upstream distribution channel, other channels are not maintained by me.
- PyPI: https://pypi.org/project/certbot-plugin-gandi/
- Archlinux: https://aur.archlinux.org/packages/certbot-dns-gandi-git/
- Debian: https://packages.debian.org/sid/main/python3-certbot-dns-gandi
- Ubuntu: https://packages.ubuntu.com/kinetic/python3-certbot-dns-gandi
- Snap: Not yet packaged. I'm lazy.
Latests builds are also available on Launchpad: https://launchpad.net/ubuntu/+source/python-certbot-dns-gandi
Be careful, installing this plugin with PyPI will also install certbot via PyPI which may conflict with any other certbot already installed on your system.
Wildcard certificates
This plugin is particularly useful when you need to obtain a wildcard certificate using dns challenges:
certbot certonly --authenticator dns-gandi --dns-gandi-credentials /etc/letsencrypt/gandi/gandi.ini -d domain.com -d \*.domain.com --server https://acme-v02.api.letsencrypt.org/directory
Automatic renewal
You can setup automatic renewal using crontab
with the following job for weekly renewal attempts:
0 0 * * 0 certbot renew -q --authenticator dns-gandi --dns-gandi-credentials /etc/letsencrypt/gandi/gandi.ini --server https://acme-v02.api.letsencrypt.org/directory

FAQ
I have a warning telling me
Plugin legacy name certbot-plugin-gandi:dns may be removed in a future version. Please use dns instead.
Certbot had moved to remove 3rd party plugins prefixes since v1.7.0. Please switch to the new configuration format and remove any used prefix-based configuration. For the time being, you can still use prefixes, but if you do so and keep using prefix-based cli arguments, stay consistent and use prefix-based configuration in the ini file.
New post-prefix configuration for certbot>=1.7.0
--authenticator dns-gandi --dns-gandi-credentials
gandi.ini
# live dns v5 api key
dns_gandi_api_key=APIKEY
# optional organization id, remove it if not used
# if you use certbot<1.7.0 please use certbot_plugin_gandi:dns_sharing_id=SHARINGID
dns_gandi_sharing_id=SHARINGID
Legacy prefix-based configuration for certbot<1.7.0
-a certbot-plugin-gandi:dns --certbot-plugin-gandi:dns-credentials
gandi.ini
# live dns v5 api key
certbot_plugin_gandi:dns_api_key=APIKEY
# optional organization id, remove it if not used
certbot_plugin_gandi:dns_sharing_id=SHARINGID
See certbot/8131 and certbot-plugin-gandi/23 for details. Please make sure to update the configuration file to the new format.
I get a
Property "certbot_plugin_gandi:dns_api_key" not found (should be API key for Gandi account).. Skipping.
See above.
Why do you keep this plugin a third-party plugin ? Just merge it with certbot ?
This Gandi plugin is a third party plugin mainly because this plugin is not officially backed by Gandi and because Certbot does not accept new plugin submissions.
