Logs? Notifcation of renewal failure?

[joea99]

Have hacked (old school context) my way through getting acme-companion setup for a docker instance and it worked well for a time.

To access my docker app, have a reverse proxy setup on another server (Apache) through which I allow internet access to the docker app. This required some additional "hacking" my solution being to manually copy the certs to the Apache server as I did not know of a way to access them directly.

Regardless, I would manually copy the files from the nginix/docker host to the Apache host, restart it, as it was happy. Until it was not. Which related to expiration of the certs. No big deal, I could schedule a manual copy as needed. Or automate it, "someday".

Sadly, this time I found that process was not effective this time. Traced the problem to, apparently, the certs not being renewed.

Did find how to check status of certs on the docker server, how to force a renewal and a "cycle". That worked flawlessly and after copying the certs to the Apache server and restarting, all is well again.

So, at long last, I ask, how can I be notified when, if, the cert renewal process does not work properly. Ideally, being notified of success or failure when the renew attempt actually triggers, would be very, very nice.

Perhaps that is very simple and I simply am too simple to have found it, or how to enable it?

Thanks.
