- # The goal of this cronjob is to ask acmetool to check
- # the current SSL certificates and to see if some need renewal.
- # If so, it would attempt to renew.
- #
- # Various services depend on these certificates and would need to be restarted.
- # This is not our concern here. We simply make sure the certificates are up to date.
- # Restarting of services happens on its own different schedule (other cronjobs).
- #
- #
- # How renewal works?
- #
- # acmetool will fail to bind to port :80 (because matrix-nginx-proxy is running there),
- # and will fall back to its "webroot" validation method.
- #
- # Thus, it would put validation files in `/var/run/acme/acme-challenge`.
- # These files can be retrieved via any vhost on port 80 of matrix-nginx-proxy,
- # because it aliases `/.well-known/acme-challenge` to that same directory.
