Exports pod labels as prometheus metrics to facilitate metric aggregation.
Configure the comma separed list of label prefix to be exporte with the parameter --label-prefix. The default prefixes are le__ and l__.
For example, to export the labels starting with application.label or application.process, configure the label-exporter command with --label-prefix="application.label,application.process", updating the file: manifest/exporter.yaml.
The main reason to configure label prefixes is to minimize the metric cardinality and avoid prometheus overhead. But, for some use cases, the user might want to expose all pod labels of all pods in the system. To enable that, use the paramenter --expose-all=true.
The prometheus metric will be: pod_label_exporter(pod_name, pod_namespace, ...)
To create a docker container just do make build_image
You will need to load the image with ./script/load-images-to-kind.sh
The pre-requisit is to have prometheus already installed.
kubectl create -f manifest/
