---

`Prometheus` exporter for x509 certificates written in Go. `node-cert-exporter` will parse SSL certificates in a number of directories recursively and expose their expiry as a Prometheus metric at `/metrics`. It can run on `Kubernetes` as a `Deployment` or `DaemonSet`, or using `Docker`. 

*This project is currently in beta and is looking for contributors. Feel free to leave your feedback using issues or pull requests.*
