export_certificates(acme_file, output_dir)

Docker

There is also a Docker image that create a cron job that runs the certificate export process on a schedule.

The container needs to have access to the store file generated by Traefik, so it needs to be configured with the correct variables to run successfully.

You can use the docker compose example to create your own environment.
