Is it possible to use this exporter to monitor PEM files within each pod?
As far as I understand from the documentation, PEM files can only be monitored locally from the exporter pod itself or from the host using a daemonset. I would like to be able to monitor files within each cluster pod
It should be. If you attach this container as a sidecar it can share the same volumes as the "main" container. Then you can configure cert-exporter to read the pem files on the shared volume.
