certbot-vscale is a Docker image based on the latest Certbot image for obtaining Let's Encrypt certificates if you use VScale DNS management.
This image extends the original certbot/certbot image with two scripts:
authenticator.pycleanup.py
It makes a request to the VScale API to create a TXT record for the DNS challenge. The record is cleaned up after verification.
Pass your API token (found in the control panel) as an environment variable and mount your target volume to the container to store certificates.
Here, Docker's volume srv_letsencrypt-data is mounted, but you can use any other directory.
$ docker run \
--rm \
--name certbot \
-e API_TOKEN=[...] \
-v srv_letsencrypt-data:/etc/letsencrypt \
