A Prometheus exporter that publishes certificate expirations from disk and Kubernetes secrets
cert-exporter is a Prometheus exporter that publishes certificate expiration information. It parses x509 certificates
stored on disk (PEM and PKCS#12), embedded in kubeconfig files, and stored in Kubernetes secrets, configmaps, admission
webhooks, and cert-manager CertificateRequest resources, then exposes their expiration as Prometheus metrics.
