prometheus-to-sd
prometheus-to-sd is a simple component that can scrape metrics stored in prometheus text format from one or multiple components and push them to the Stackdriver
TL;DR;
$ helm install stable/prometheus-to-sd
Prerequisites
- a service exposing metrics in prometheus format
- k8s cluster should run on GCE or GKE
Installing the Chart
To install the chart with the release name my-release:
$ helm install --name my-release stable/prometheus-to-sd
The command deploys prometheus-to-sd on the Kubernetes cluster in the default configuration.
Uninstalling the Chart
To uninstall/delete the my-release deployment:
$ helm delete my-release
The command removes all the Kubernetes components associated with the chart and deletes the release.
Configuration
The following tables lists the configurable parameters and their default values.
| Parameter | Description | Default |

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,
$ helm install --name my-release \
--set "metricsSources.kube-state-metrics=http://kube-state-metrics:8080" \

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
$ helm install --name my-release -f values.yaml stable/prometheus-to-sd
Multiple metrics sources can be defined.
