Automate Let's Encrypt certificate issuance, renewal and synchronize with CleverCloud.

Let's Automate

Automate Let's Encrypt certificate issuance, renewal and synchronize with CleverCloud (or any API-drivable hosting service).

Description

Let's automate allows you to create Let's Encrypt certificates and publish them to Clever Cloud with automatic renewal (or any API-drivable hosting service if you want to contribute). Let's automate needs an OVH account in order to create DNS records to perform the Let's Encrypt DNS challenge. Let's automate is also integrated with Teams so all the events may be published to a dedicated topic.

Disclamer

Let's Automate is integrated with Otoroshi (only used for authentication), OVH, Clever Cloud and Teams. For the moment there is no other providers available. If you need this tool with any other DNS provider or hosting provider your contributions are welcome!

Run the app with clever cloud

First create a postgresql add on.

Then create a java app and set the following env variables :

APP_ENV=prod
CACHE_DEPENDENCIES=true
