Overview

This component is tasked with the creation of a generic scraper, according to the description given in a Custom Resource (CR). After the creation of the CR, the operator reads the "scraper" configuration part and creates two resources: a deployment with a generic prometheus scraper inside and a configmap containing the configuration. The scraper parses the prometheus data and obtains the given database-config to upload all metrics to a database.
