 Container Resource Exporter (CRE) is a metrics expoerter which will provide the *container* resource `request/limit/usage` metrics data on realtime in the [Prometheus](https://prometheus.io/) format. This can be utilized to trigger a pro-active alert from the the [Prometheus Alert Manager](https://prometheus.io/docs/alerting/alertmanager).
