| # helm-exporter | ||
|
|
||
| Installs [helm-exporter](https://github.com/sstarcher/helm-exporter) to export helm stats to prometheus. | ||
|
|
||
| ## TL;DR; | ||
|
|
||
| ```console | ||
| $ helm install sstarcher/helm-exporter | ||
| ``` | ||
|
|
||
| ## Introduction | ||
|
|
||
| This chart bootstraps a [helm-exporter](https://github.com/sstarcher/helm-exporter) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager. | ||
|
|
||
| The chart comes with a ServiceMonitor for use with the [Prometheus Operator](https://github.com/helm/charts/tree/master/stable/prometheus-operator). | ||
|
|
||
| ## Installing the Chart | ||
|
|
||
| To install the chart with the release name `my-release`: | ||
|
|
||
| ```console | ||
| $ helm install sstarcher/helm-exporter --name my-release | ||
| ``` | ||
|
|
||
| The command deploys helm-exporter on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation. | ||
|
|
||
| ## Uninstalling the Chart | ||
|
|
||
| To uninstall/delete the `my-release` deployment: | ||
|
|
||
| ```console | ||
| $ helm delete my-release | ||
| ``` | ||
|
|
||
| The command removes all the Kubernetes components associated with the chart and deletes the release. | ||
|
|
||
| ## Configuration | ||
|
|
||
| The following table lists the configurable parameters of the helm-exporter chart that are in addition to values in a default helm chart. | ||
|
|
||
| Parameter | Description | Default | ||
| --- | --- | --- | ||
| `namespaces` | Specifies which namespaces to query for helm 3 metrics. Defaults to all | "" | ||
| `serviceMonitor.create` | Set to true if using the Prometheus Operator | `false` | ||
| `serviceMonitor.interval` | Interval at which metrics should be scraped | `` | ||
| `serviceMonitor.namespace` | The namespace where the Prometheus Operator is deployed | `` | ||
| `serviceMonitor.additionalLabels` | Additional labels to add to the ServiceMonitor | `{}` | ||
| ```console | ||
| $ helm install my-release sstarcher/helm-exporter | ||
| ``` | ||
|
|
||
| Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example, | ||
|
|
||
| ```console | ||
| $ helm install my-release sstarcher/helm-exporter -f values.yaml | ||
| ``` | ||
|
|
||
| > **Tip**: You can use the default [values.yaml](values.yaml) |
