Force certificates renewal

If needed, you can force a running acme-companion container to renew all certificates that are currently in use with the following command:

$ docker exec nginx-proxy-acme /app/force_renew

Manually trigger the service loop

You can trigger the execution of the service loop before the hourly execution with:

$ docker exec nginx-proxy-acme /app/signal_le_service

Unlike the previous command, this won't force renewal of certificates that don't need to be renewed.

Show certificates informations

To display informations about your existing certificates, use the following command:

$ docker exec nginx-proxy-acme /app/cert_status
