# kube-prometheus-stack
Installs core components of the [kube-prometheus stack](https://github.com/prometheus-operator/kube-prometheus), a collection of Kubernetes manifests, [Grafana](http://grafana.com/) dashboards, and [Prometheus rules](https://prometheus.io/docs/prometheus/latest/configuration/recording_rules/) combined with documentation and scripts to provide easy to operate end-to-end Kubernetes cluster monitoring with [Prometheus](https://prometheus.io/) using the [Prometheus Operator](https://github.com/prometheus-operator/prometheus-operator).
See the [kube-prometheus](https://github.com/prometheus-operator/kube-prometheus) readme for details about components, dashboards, and alerts.
_Note: This chart was formerly named `prometheus-operator` chart, now renamed to more clearly reflect that it installs the `kube-prometheus` project stack, within which Prometheus Operator is only one component. This chart does not install all components of `kube-prometheus`, notably excluding the Prometheus Adapter and Prometheus black-box exporter._
## Prerequisites
- Kubernetes 1.19+
- Helm 3+
## Usage
The chart is distributed as an [OCI Artifact](https://helm.sh/docs/topics/registries/) as well as via a traditional [Helm Repository](https://helm.sh/docs/topics/chart_repository/).
- OCI Artifact: `oci://ghcr.io/prometheus-community/charts/kube-prometheus-stack`
- Helm Repository: `https://prometheus-community.github.io/helm-charts` with chart `kube-prometheus-stack`
The installation instructions use the OCI registry. Refer to the [`helm repo`]([`helm repo`](https://helm.sh/docs/helm/helm_repo/)) command documentation for information on installing charts via the traditional repository.
### Install Helm Chart
```console
helm install [RELEASE_NAME] oci://ghcr.io/prometheus-community/charts/kube-prometheus-stack
```
_See [configuration](#configuration) below._
_See [helm install](https://helm.sh/docs/helm/helm_install/) for command documentation._
### Dependencies
By default this chart installs additional, dependent charts:
- [prometheus-community/kube-state-metrics](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-state-metrics)
- [prometheus-community/prometheus-node-exporter](https://github.com/prometheus-community/helm-charts/tree/main/charts/prometheus-node-exporter)
- [grafana/grafana](https://github.com/grafana/helm-charts/tree/main/charts/grafana)
To disable dependencies during installation, see [multiple releases](#multiple-releases) below.
_See [helm dependency](https://helm.sh/docs/helm/helm_dependency/) for command documentation._
#### Grafana Dashboards
This chart provisions a collection of curated Grafana dashboards that are automatically loaded into Grafana via ConfigMaps. These dashboards are rendered into the Helm chart under [`templates/grafana/`](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack/templates/grafana/), but **this is not their source of truth**.
The dashboards originate from various upstream projects and are gathered and processed using scripts in the [`hack/`](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack/hack) directory. For details on how these dashboards are sourced and kept up to date, refer to the [hack/README.md](https://github.com/prometheus-community/helm-charts/blob/main/charts/kube-prometheus-stack/hack/README.md).
> **Note:** The dashboards referenced in the `hack` scripts are usually **not the original source** either. Most originate from separate **Prometheus mixin repositories** (e.g., [kubernetes-mixin](https://github.com/kubernetes-monitoring/kubernetes-mixin)) and are processed through `jsonnet` tooling before being included here. To find the original source in case you want to modify it you may have to search even further upstream.
If you wish to contribute or modify dashboards, please follow the guidance in the `hack/README.md` to ensure consistency and reproducibility.
### Uninstall Helm Chart
```console
helm uninstall [RELEASE_NAME]
```
This removes all the Kubernetes components associated with the chart and deletes the release.
_See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation._
CRDs created by this chart are not removed by default and should be manually cleaned up:
```console
kubectl delete crd alertmanagerconfigs.monitoring.coreos.com
kubectl delete crd alertmanagers.monitoring.coreos.com
kubectl delete crd podmonitors.monitoring.coreos.com
kubectl delete crd probes.monitoring.coreos.com
kubectl delete crd prometheusagents.monitoring.coreos.com
kubectl delete crd prometheuses.monitoring.coreos.com
kubectl delete crd prometheusrules.monitoring.coreos.com
kubectl delete crd scrapeconfigs.monitoring.coreos.com
kubectl delete crd servicemonitors.monitoring.coreos.com
kubectl delete crd thanosrulers.monitoring.coreos.com
```
### Upgrading Chart
```console
helm upgrade [RELEASE_NAME] [CHART]
```
With Helm v3, CRDs created by this chart are not updated by default and should be manually updated.
Consult also the [Helm Documentation on CRDs](https://helm.sh/docs/chart_best_practices/custom_resource_definitions).
CRDs update lead to a major version bump.
The Chart's [appVersion](https://github.com/prometheus-community/helm-charts/blob/13ed7098db2f78c2bbcdab6c1c3c7a95b4b94574/charts/kube-prometheus-stack/Chart.yaml#L36) refers to the [`prometheus-operator`](https://github.com/prometheus-operator/prometheus-operator/tree/main)'s version with matching CRDs.
_See [helm upgrade](https://helm.sh/docs/helm/helm_upgrade/) for command documentation._
#### Upgrading an existing Release to a new major version
A major chart version change (like v1.2.3 -> v2.0.0) indicates that there is an incompatible breaking change needing manual actions.
See [UPGRADE.md](https://github.com/prometheus-community/helm-charts/blob/main/charts/kube-prometheus-stack/UPGRADE.md)
for breaking changes between versions.
## Configuration
See [Customizing the Chart Before Installing](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing). To see all configurable options with detailed comments:
```console
helm show values oci://ghcr.io/prometheus-community/charts/kube-prometheus-stack
```
You may also `helm show values` on this chart's [dependencies](#dependencies) for additional options.
For templated Grafana datasource definitions (e.g. when using Helm flow control), use `grafana.additionalDataSourcesString`, which is rendered via `tpl`.
### Prometheus High Availability (HA)
For a basic HA setup, run multiple Prometheus replicas:
```yaml
prometheus:
prometheusSpec:
replicas: 2
podAntiAffinity: "hard"
externalLabels:
cluster: prod-eu1
```
Important notes:
1. `replicas` controls how many Prometheus pods are deployed for each shard.
2. Keep anti-affinity enabled (or hardened) to avoid scheduling all replicas on one node.
3. Do not clear replica/instance external labels in HA setups (`replicaExternalLabelNameClear` / `prometheusExternalLabelNameClear`), otherwise deduplication and alert/source identification become harder.
4. Querying replicas through a Kubernetes Service provides availability, but not sample deduplication across replicas by itself. For global/deduplicated querying, use a Thanos Query layer (or another backend that performs deduplication).
See also Prometheus Operator HA guidance:
- [Prometheus Operator HA docs](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/platform/high-availability.md#prometheus)
### Multiple releases
The same chart can be used to run multiple Prometheus instances in the same cluster if required. To achieve this, it is necessary to run only one instance of prometheus-operator and a pair of alertmanager pods for an HA configuration, while all other components need to be disabled. To disable a dependency during installation, set `kubeStateMetrics.enabled`, `nodeExporter.enabled` and `grafana.enabled` to `false`.
## Work-Arounds for Known Issues
### Running on private GKE clusters
When Google configure the control plane for private clusters, they automatically configure VPC peering between your Kubernetes cluster’s network and a separate Google managed project. In order to restrict what Google are able to access within your cluster, the firewall rules configured restrict access to your Kubernetes pods. This means that in order to use the webhook component with a GKE private cluster, you must configure an additional firewall rule to allow the GKE control plane access to your webhook pod.
You can read more information on how to add firewall rules for the GKE control plane nodes in the [GKE docs](https://cloud.google.com/kubernetes-engine/docs/how-to/private-clusters#add_firewall_rules)
Alternatively, you can disable the hooks by setting `prometheusOperator.admissionWebhooks.enabled=false`.
## PrometheusRules Admission Webhooks
With Prometheus Operator version 0.30+, the core Prometheus Operator pod exposes an endpoint that will integrate with the `validatingwebhookconfiguration` Kubernetes feature to prevent malformed rules from being added to the cluster.
### How the Chart Configures the Hooks
A validating and mutating webhook configuration requires the endpoint to which the request is sent to use TLS. It is possible to set up custom certificates to do this, but in most cases, a self-signed certificate is enough. The setup of this component requires some more complex orchestration when using helm. The steps are created to be idempotent and to allow turning the feature on and off without running into helm quirks.
1. A pre-install hook provisions a certificate into the same namespace using a format compatible with provisioning using end user certificates. If the certificate already exists, the hook exits.
2. The prometheus operator pod is configured to use a TLS proxy container, which will load that certificate.
3. Validating and Mutating webhook configurations are created in the cluster, with their failure mode set to Ignore. This allows rules to be created by the same chart at the same time, even though the webhook has not yet been fully set up - it does not have the correct CA field set.
4. A post-install hook reads the CA from the secret created by step 1 and patches the Validating and Mutating webhook configurations. This process will allow a custom CA provisioned by some other process to also be patched into the webhook configurations. The chosen failure policy is also patched into the webhook configurations
### Alternatives
It should be possible to use [jetstack/cert-manager](https://github.com/jetstack/cert-manager) if a more complete solution is required, but it has not been tested.
You can enable automatic self-signed TLS certificate provisioning via cert-manager by setting the `prometheusOperator.admissionWebhooks.certManager.enabled` value to true.
### Limitations
Because the operator can only run as a single pod, there is potential for this component failure to cause rule deployment failure. Because this risk is outweighed by the benefit of having validation, the feature is enabled by default.
## Developing Prometheus Rules and Grafana Dashboards
This chart Grafana Dashboards and Prometheus Rules are just a copy from [prometheus-operator/prometheus-operator](https://github.com/prometheus-operator/prometheus-operator) and other sources, synced (with alterations) by scripts in [hack](hack) folder. In order to introduce any changes you need to first [add them to the original repository](https://github.com/prometheus-operator/kube-prometheus/blob/main/docs/customizations/developing-prometheus-rules-and-grafana-dashboards.md) and then sync there by scripts.
## Further Information
For more in-depth documentation of configuration options meanings, please see
- [Prometheus Operator](https://github.com/prometheus-operator/prometheus-operator)
- [Prometheus](https://prometheus.io/docs/introduction/overview/)
- [Grafana](https://github.com/grafana/helm-charts/tree/main/charts/grafana#grafana-helm-chart)
## prometheus.io/scrape
The prometheus operator does not support annotation-based discovery of services, using the `PodMonitor` or `ServiceMonitor` CRD in its place as they provide far more configuration options.
For information on how to use PodMonitors/ServiceMonitors, please see the documentation on the `prometheus-operator/prometheus-operator` documentation here:
- [ServiceMonitors](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/developer/getting-started.md#using-servicemonitors)
- [PodMonitors](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/developer/getting-started.md#using-podmonitors)
- [Running Exporters](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/user-guides/running-exporters.md)
By default, Prometheus discovers PodMonitors and ServiceMonitors within its namespace, that are labeled with the same release tag as the prometheus-operator release.
Sometimes, you may need to discover custom PodMonitors/ServiceMonitors, for example used to scrape data from third-party applications.
An easy way of doing this, without compromising the default PodMonitors/ServiceMonitors discovery, is allowing Prometheus to discover all PodMonitors/ServiceMonitors within its namespace, without applying label filtering.
To do so, you can set `prometheus.prometheusSpec.podMonitorSelectorNilUsesHelmValues` and `prometheus.prometheusSpec.serviceMonitorSelectorNilUsesHelmValues` to `false`.
## Migrating from stable/prometheus-operator chart
## Zero downtime
Since `kube-prometheus-stack` is fully compatible with the `stable/prometheus-operator` chart, a migration without downtime can be achieved.
However, the old name prefix needs to be kept. If you want the new name please follow the step by step guide below (with downtime).
You can override the name to achieve this:
```console
helm upgrade prometheus-operator prometheus-community/kube-prometheus-stack -n monitoring --reuse-values --set nameOverride=prometheus-operator
```
**Note**: It is recommended to run this first with `--dry-run --debug`.
## Redeploy with new name (downtime)
If the **prometheus-operator** values are compatible with the new **kube-prometheus-stack** chart, please follow the below steps for migration:
> The guide presumes that chart is deployed in `monitoring` namespace and the deployments are running there. If in other namespace, please replace the `monitoring` to the deployed namespace.
1. Patch the PersistenceVolume created/used by the prometheus-operator chart to `Retain` claim policy:
```console
kubectl patch pv/<PersistentVolume name> -p '{"spec":{"persistentVolumeReclaimPolicy":"Retain"}}'
```
**Note:** To execute the above command, the user must have a cluster wide permission. Please refer [Kubernetes RBAC](https://kubernetes.io/docs/reference/access-authn-authz/rbac/)
2. Uninstall the **prometheus-operator** release and delete the existing PersistentVolumeClaim, and verify PV become Released.
```console
helm uninstall prometheus-operator -n monitoring
kubectl delete pvc/<PersistenceVolumeClaim name> -n monitoring
```
Additionally, you have to manually remove the remaining `prometheus-operator-kubelet` service.
```console
kubectl delete service/prometheus-operator-kubelet -n kube-system
```
You can choose to remove all your existing CRDs (ServiceMonitors, Podmonitors, etc.) if you want to.
3. Remove current `spec.claimRef` values to change the PV's status from Released to Available.
```console
kubectl patch pv/<PersistentVolume name> --type json -p='[{"op": "remove", "path": "/spec/claimRef"}]' -n monitoring
```
**Note:** To execute the above command, the user must have a cluster wide permission. Please refer to [Kubernetes RBAC](https://kubernetes.io/docs/reference/access-authn-authz/rbac/)
After these steps, proceed to a fresh **kube-prometheus-stack** installation and make sure the current release of **kube-prometheus-stack** matching the `volumeClaimTemplate` values in the `values.yaml`.
The binding is done via matching a specific amount of storage requested and with certain access modes.
For example, if you had storage specified as this with **prometheus-operator**:
```yaml
volumeClaimTemplate:
spec:
storageClassName: gp2
accessModes: ["ReadWriteOnce"]
resources:
requests:
storage: 50Gi
```
You have to specify matching `volumeClaimTemplate` with 50Gi storage and `ReadWriteOnce` access mode.
Additionally, you should check the current AZ of your legacy installation's PV, and configure the fresh release to use the same AZ as the old one. If the pods are in a different AZ than the PV, the release will fail to bind the existing one, hence creating a new PV.
This can be achieved either by specifying the labels through `values.yaml`, e.g. setting `prometheus.prometheusSpec.nodeSelector` to:
```yaml
nodeSelector:
failure-domain.beta.kubernetes.io/zone: east-west-1a
```
or passing these values as `--set` overrides during installation.
The new release should now re-attach your previously released PV with its content.
## Migrating from coreos/prometheus-operator chart
The multiple charts have been combined into a single chart that installs prometheus operator, prometheus, alertmanager, grafana as well as the multitude of exporters necessary to monitor a cluster.
There is no simple and direct migration path between the charts as the changes are extensive and intended to make the chart easier to support.
The capabilities of the old chart are all available in the new chart, including the ability to run multiple prometheus instances on a single cluster - you will need to disable the parts of the chart you do not wish to deploy.
You can check out the tickets for this change at [prometheus-operator/prometheus-operator #592](https://github.com/prometheus-operator/prometheus-operator/issues/592) and [helm/charts #6765](https://github.com/helm/charts/pull/6765).
### High-level overview of Changes
#### Added dependencies
The chart has added 3 [dependencies](#dependencies).
- Node-Exporter, Kube-State-Metrics: These components are loaded as dependencies into the chart, and are relatively simple components
- Grafana: The Grafana chart is more feature-rich than this chart - it contains a sidecar that is able to load data sources and dashboards from configmaps deployed into the same cluster. For more information check out the [documentation for the chart](https://github.com/grafana/helm-charts/blob/main/charts/grafana/README.md)
#### Kubelet Service
Because the kubelet service has a new name in the chart, make sure to clean up the old kubelet service in the `kube-system` namespace to prevent counting container metrics twice.
#### Persistent Volumes
If you would like to keep the data of the current persistent volumes, it should be possible to attach existing volumes to new PVCs and PVs that are created using the conventions in the new chart. For example, in order to use an existing Azure disk for a helm release called `prometheus-migration` the following resources can be created:
```yaml
apiVersion: v1
kind: PersistentVolume
metadata:
name: pvc-prometheus-migration-prometheus-0
spec:
accessModes:
- ReadWriteOnce
azureDisk:
cachingMode: None
diskName: pvc-prometheus-migration-prometheus-0
diskURI: /subscriptions/f5125d82-2622-4c50-8d25-3f7ba3e9ac4b/resourceGroups/sample-migration-resource-group/providers/Microsoft.Compute/disks/pvc-prometheus-migration-prometheus-0
fsType: ""
kind: Managed
readOnly: false
capacity:
storage: 1Gi
persistentVolumeReclaimPolicy: Delete
storageClassName: prometheus
volumeMode: Filesystem
```
```yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
labels:
app.kubernetes.io/name: prometheus
prometheus: prometheus-migration-prometheus
name: prometheus-prometheus-migration-prometheus-db-prometheus-prometheus-migration-prometheus-0
namespace: monitoring
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
storageClassName: prometheus
volumeMode: Filesystem
volumeName: pvc-prometheus-migration-prometheus-0
```
The PVC will take ownership of the PV and when you create a release using a persistent volume claim template it will use the existing PVCs as they match the naming convention used by the chart. For other cloud providers similar approaches can be used.
#### KubeProxy
The metrics bind address of kube-proxy is default to `127.0.0.1:10249` that prometheus instances **cannot** access to. You should expose metrics by changing `metricsBindAddress` field value to `0.0.0.0:10249` if you want to collect them.
Depending on the cluster, the relevant part `config.conf` will be in ConfigMap `kube-system/kube-proxy` or `kube-system/kube-proxy-config`. For example:
```console
kubectl -n kube-system edit cm kube-proxy
```
```yaml
apiVersion: v1
data:
config.conf: |-
apiVersion: kubeproxy.config.k8s.io/v1alpha1
kind: KubeProxyConfiguration
# ...
# metricsBindAddress: 127.0.0.1:10249
metricsBindAddress: 0.0.0.0:10249
# ...
kubeconfig.conf: |-
# ...
kind: ConfigMap
metadata:
labels:
app: kube-proxy
name: kube-proxy
namespace: kube-system
```

# Grafana Helm Chart
The leading tool for querying and visualizing time series and metrics.
## Source Code
* <https://github.com/grafana/grafana>
## Requirements
Kubernetes: `^1.25.0-0`
## Installing the Chart
### OCI Registry
OCI registries are preferred in Helm as they implement unified storage, distribution, and improved security.
```console
helm install RELEASE-NAME oci://ghcr.io/grafana-community/helm-charts/grafana
```
### HTTP Registry
```console
helm repo add grafana-community https://grafana-community.github.io/helm-charts
helm repo update
helm install RELEASE-NAME grafana-community/grafana
```
## Uninstalling the Chart
To remove all of the Kubernetes objects associated with the Helm chart release:
```console
helm delete RELEASE-NAME
```
## Changelog
See the [changelog](https://grafana-community.github.io/helm-charts/changelog/?chart=grafana).
---
## Upgrading
A major chart version change (like v1.2.3 -> v2.0.0) indicates that there is an
incompatible breaking change needing manual actions.
### To 4.0.0 (And 3.12.1)
This version requires Helm >= 2.12.0.
### To 5.0.0
You have to add --force to your helm upgrade command as the labels of the chart have changed.
### To 6.0.0
This version requires Helm >= 3.1.0.
### To 7.0.0
For consistency with other Helm charts, the `global.image.registry` parameter was renamed
to `global.imageRegistry`. If you were not previously setting `global.image.registry`, no action
is required on upgrade. If you were previously setting `global.image.registry`, you will
need to instead set `global.imageRegistry`.
### To 10.0.0
Static alerting resources now support Helm templating. This means that alerting resources loaded from external files (`alerting.*.files`) are now processed by the Helm template engine.
If you already use template expressions intended for Alertmanager (for example, `{{ $labels.instance }}`), these must now be escaped to avoid unintended Helm or Go template evaluation. To escape them, wrap the braces with an extra layer like this:
`{{ "{{" }} $labels.instance {{ "}}" }}`
This ensures the expressions are preserved for Alertmanager instead of being rendered by Helm.
### To 11.0.0
The minimum required Kubernetes version is now 1.25. All references to deprecated APIs have been removed.
## Configuration
### Example ingress with path
With grafana 6.3 and above
```yaml
grafana.ini:
server:
domain: monitoring.example.com
root_url: "%(protocol)s://%(domain)s/grafana"
serve_from_sub_path: true
ingress:
enabled: true
hosts:
- "monitoring.example.com"
path: "/grafana"
```
### Example of extraVolumeMounts and extraVolumes
Configure additional volumes with `extraVolumes` and volume mounts with `extraVolumeMounts`.
Example for `extraVolumeMounts` and corresponding `extraVolumes`:
```yaml
extraVolumeMounts:
- name: plugins
mountPath: /var/lib/grafana/plugins
subPath: configs/grafana/plugins
readOnly: false
- name: dashboards
mountPath: /var/lib/grafana/dashboards
hostPath: /usr/shared/grafana/dashboards
readOnly: false
extraVolumes:
- name: plugins
existingClaim: existing-grafana-claim
- name: dashboards
hostPath: /usr/shared/grafana/dashboards
```
Volumes default to `emptyDir`. Set to `persistentVolumeClaim`,
`hostPath`, `csi`, or `configMap` for other types. For a
`persistentVolumeClaim`, specify an existing claim name with
`existingClaim`.
## Import dashboards
There are a few methods to import dashboards to Grafana. Below are some examples and explanations as to how to use each method:
```yaml
dashboards:
default:
some-dashboard:
json: |
{
"annotations":
...
# Complete json file here
...
"title": "Some Dashboard",
"uid": "abcd1234",
"version": 1
}
custom-dashboard:
# This is a path to a file inside the dashboards directory inside the chart directory
file: dashboards/custom-dashboard.json
prometheus-stats:
# Ref: https://grafana.com/dashboards/2
# title: My Custom Title # optional; when set for a downloaded dashboard (gnetId or url), overrides the title displayed in Grafana
gnetId: 2
revision: 2
datasource: Prometheus
loki-dashboard-quick-search:
gnetId: 12019
revision: 2
datasource:
- name: DS_PROMETHEUS
value: Prometheus
- name: DS_LOKI
value: Loki
local-dashboard:
url: https://github.com/cloudnative-pg/grafana-dashboards/blob/main/charts/cluster/grafana-dashboard.json
# redirects to:
# https://raw.githubusercontent.com/cloudnative-pg/grafana-dashboards/refs/heads/main/charts/cluster/grafana-dashboard.json
# default: -skf
# -s - silent mode
# -k - allow insecure (eg: non-TLS) connections
# -f - fail fast
# -L - follow HTTP redirects
curlOptions: -Lf
```
## BASE64 dashboards
Dashboards could be stored on a server that does not return JSON directly and instead of it returns a base64 encoded file (e.g. Gerrit)
A new parameter has been added to the URL use case so if you specify a b64content value equals to true after the URL entry a base64 decoding is applied before save the file to disk.
If this entry is not set or is equals to false not decoding is applied to the file before saving it to disk.
### Gerrit use case
Gerrit API for download files has the following schema: <https://yourgerritserver/a/{project-name}/branches/{branch-id}/files/{file-id}/content> where {project-name} and
{file-id} usually has '/' in their values and so they MUST be replaced by %2F so if project-name is user/repository, branch-id is master and file-id is equals to dir1/dir2/dashboard
the URL value is <https://yourgerritserver/a/user%2Frepo/branches/master/files/dir1%2Fdir2%2Fdashboard/content>
## Sidecar for dashboards
If the parameter `sidecar.dashboards.enabled` is set, a sidecar container is deployed in the grafana
pod. This container watches all configmaps (or secrets) in the cluster and filters out the ones with
a label as defined in `sidecar.dashboards.label`. The files defined in those configmaps are written
to a folder and accessed by grafana. Changes to the configmaps are monitored and the imported
dashboards are deleted/updated.
A recommendation is to use one configmap per dashboard, as a reduction of multiple dashboards inside
one configmap is currently not properly mirrored in grafana.
Example dashboard config:
```yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: sample-grafana-dashboard
labels:
grafana_dashboard: "1"
data:
k8s-dashboard.json: |-
[...]
```
## Sidecar for datasources
If the parameter `sidecar.datasources.enabled` is set, an init container is deployed in the grafana
pod. This container lists all secrets (or configmaps, though not recommended) in the cluster and
filters out the ones with a label as defined in `sidecar.datasources.label`. The files defined in
those secrets are written to a folder and accessed by grafana on startup. Using these YAML files,
the data sources in grafana can be imported.
Should you aim for reloading datasources in Grafana each time the config is changed, set `sidecar.datasources.skipReload: false` and adjust `sidecar.datasources.reloadURL` to `http://<svc-name>.<namespace>.svc.cluster.local/api/admin/provisioning/datasources/reload`.
Secrets are recommended over configmaps for this usecase because datasources usually contain private
data like usernames and passwords. Secrets are the more appropriate cluster resource to manage those.
Example values to add a postgres datasource as a kubernetes secret:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: grafana-datasources
labels:
grafana_datasource: 'true' # default value for: sidecar.datasources.label
stringData:
pg-db.yaml: |-
apiVersion: 1
datasources:
- name: My pg db datasource
type: postgres
url: my-postgresql-db:5432
user: db-readonly-user
secureJsonData:
password: 'SUperSEcretPa$$word'
jsonData:
database: my_datase
sslmode: 'disable' # disable/require/verify-ca/verify-full
maxOpenConns: 0 # Grafana v5.4+

## Sidecar for notifiers
If the parameter `sidecar.notifiers.enabled` is set, an init container is deployed in the grafana
pod. This container lists all secrets (or configmaps, though not recommended) in the cluster and
filters out the ones with a label as defined in `sidecar.notifiers.label`. The files defined in
those secrets are written to a folder and accessed by grafana on startup. Using these YAML files,
the notification channels in grafana can be imported. The secrets must be created before
`helm install` so that the notifiers init container can list the secrets.
Secrets are recommended over configmaps for this usecase because alert notification channels usually contain
private data like SMTP usernames and passwords. Secrets are the more appropriate cluster resource to manage those.
Example datasource config adapted from [Grafana](https://grafana.com/docs/grafana/latest/administration/provisioning/#alert-notification-channels):
```yaml
notifiers:
- name: notification-channel-1
type: slack
uid: notifier1
# either
org_id: 2
# or
org_name: Main Org.
is_default: true
send_reminder: true
frequency: 1h
disable_resolve_message: false
# See `Supported Settings` section for settings supporter for each
# alert notification type.
settings:
recipient: 'XXX'
token: 'xoxb'
uploadImage: true
url: https://slack.com
delete_notifiers:
- name: notification-channel-1
uid: notifier1
org_id: 2
- name: notification-channel-2
# default org_id: 1
```
## Sidecar for alerting resources
If the parameter `sidecar.alerts.enabled` is set, a sidecar container is deployed in the grafana
pod. This container watches all configmaps (or secrets) in the cluster (namespace defined by `sidecar.alerts.searchNamespace`) and filters out the ones with
a label as defined in `sidecar.alerts.label` (default is `grafana_alert`). The files defined in those configmaps are written
to a folder and accessed by grafana. Changes to the configmaps are monitored and the imported alerting resources are updated, however, deletions are a little more complicated (see below).
This sidecar can be used to provision alert rules, contact points, notification policies, notification templates and mute timings as shown in [Grafana Documentation](https://grafana.com/docs/grafana/next/alerting/set-up/provision-alerting-resources/file-provisioning/).
To fetch the alert config which will be provisioned, use the alert provisioning API ([Grafana Documentation](https://grafana.com/docs/grafana/next/developers/http_api/alerting_provisioning/)).
You can use either JSON or YAML format.
Example config for an alert rule:
```yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: sample-grafana-alert
labels:
grafana_alert: "1"
data:
k8s-alert.yml: |-
apiVersion: 1
groups:
- orgId: 1
name: k8s-alert
[...]
```
To delete provisioned alert rules is a two step process, you need to delete the configmap which defined the alert rule
and then create a configuration which deletes the alert rule.
Example deletion configuration:
```yaml
apiVersion: v1
kind: ConfigMap
metadata:
name: delete-sample-grafana-alert
namespace: monitoring
labels:
grafana_alert: "1"
data:
delete-k8s-alert.yml: |-
apiVersion: 1
deleteRules:
- orgId: 1
uid: 16624780-6564-45dc-825c-8bded4ad92d3
```
## Statically provision alerting resources
If you don't need to change alerting resources (alert rules, contact points, notification policies and notification templates) regularly you could use the `alerting` config option instead of the sidecar option above.
This will grab the alerting config and apply it statically at build time for the helm file.
There are two methods to statically provision alerting configuration in Grafana. Below are some examples and explanations as to how to use each method:
```yaml
alerting:
team1-alert-rules.yaml:
file: alerting/team1/rules.yaml
team2-alert-rules.yaml:
file: alerting/team2/rules.yaml
team3-alert-rules.yaml:
file: alerting/team3/rules.yaml
notification-policies.yaml:
file: alerting/shared/notification-policies.yaml
notification-templates.yaml:
file: alerting/shared/notification-templates.yaml
contactpoints.yaml:
apiVersion: 1
contactPoints:
- orgId: 1
name: Slack channel
receivers:
- uid: default-receiver
type: slack
settings:
# Webhook URL to be filled in
url: ""
# We need to escape double curly braces for the tpl function.
text: '{{ `{{ template "default.message" . }}` }}'
title: '{{ `{{ template "default.title" . }}` }}'
```
The two possibilities for static alerting resource provisioning are:
* Inlining the file contents as shown for contact points in the above example.
* Importing a file using a relative path starting from the chart root directory as shown for the alert rules in the above example.
### Important notes on file provisioning
* The format of the files is defined in the [Grafana documentation](https://grafana.com/docs/grafana/next/alerting/set-up/provision-alerting-resources/file-provisioning/) on file provisioning.
* The chart supports importing YAML and JSON files.
* The filename must be unique, otherwise one volume mount will overwrite the other.
* Alerting configurations support Helm templating. Double curly braces that arise from the Grafana configuration format and are not intended as templates for the chart must be escaped.
* The number of total files under `alerting:` is not limited. Each file will end up as a volume mount in the corresponding provisioning folder of the deployed Grafana instance.
* The file size for each import is limited by what the function `.Files.Get` can handle, which suffices for most cases.
## How to serve Grafana with a path prefix (/grafana)
In order to serve Grafana with a prefix (e.g., <http://example.com/grafana>), add the following to your values.yaml.
```yaml
ingress:
enabled: true
annotations:
kubernetes.io/ingress.class: "nginx"
nginx.ingress.kubernetes.io/rewrite-target: /$1
nginx.ingress.kubernetes.io/use-regex: "true"
path: /grafana/?(.*)
hosts:
- k8s.example.dev
grafana.ini:
server:
root_url: http://localhost:3000/grafana # this host can be localhost
```
## How to securely reference secrets in grafana.ini
This example uses Grafana [file providers](https://grafana.com/docs/grafana/latest/administration/configuration/#file-provider) for secret values and the `extraSecretMounts` configuration flag (Additional grafana server secret mounts) to mount the secrets.
In grafana.ini:
```yaml
grafana.ini:
[auth.generic_oauth]
enabled = true
client_id = $__file{/etc/secrets/auth_generic_oauth/client_id}
client_secret = $__file{/etc/secrets/auth_generic_oauth/client_secret}
```
Existing secret, or created along with helm:
```yaml
---
apiVersion: v1
kind: Secret
metadata:
name: auth-generic-oauth-secret
type: Opaque
stringData:
client_id: <value>
client_secret: <value>
```
Include in the `extraSecretMounts` configuration flag:
```yaml
extraSecretMounts:
- name: auth-generic-oauth-secret-mount
secretName: auth-generic-oauth-secret
defaultMode: 0440
mountPath: /etc/secrets/auth_generic_oauth
readOnly: true
```
### extraSecretMounts using a Container Storage Interface (CSI) provider
This example uses a CSI driver e.g. retrieving secrets using [Azure Key Vault Provider](https://github.com/Azure/secrets-store-csi-driver-provider-azure)
```yaml
extraSecretMounts:
- name: secrets-store-inline
mountPath: /run/secrets
readOnly: true
csi:
driver: secrets-store.csi.k8s.io
readOnly: true
volumeAttributes:
secretProviderClass: "my-provider"
nodePublishSecretRef:
name: akv-creds
```
## Image Renderer Plug-In
This chart supports enabling [remote image rendering](https://github.com/grafana/grafana-image-renderer/blob/master/README.md#run-in-docker)
```yaml
imageRenderer:
enabled: true
```
### Image Renderer NetworkPolicy
By default the image-renderer pods will have a network policy which only allows ingress traffic from the created grafana instance
### High Availability for unified alerting
If you want to run Grafana in a high availability cluster you need to enable
the headless service by setting `headlessService: true` in your `values.yaml`
file.
As next step you have to setup the `grafana.ini` in your `values.yaml` in a way
that it will make use of the headless service to obtain all the IPs of the
cluster. For example, use ``{{ .Release.Name }}`` to refer to the Helm release name in your values.
```yaml
grafana.ini:
...
unified_alerting:
enabled: true
ha_peers: {{ .Release.Name }}-headless:9094
ha_listen_address: ${POD_IP}:9094
ha_advertise_address: ${POD_IP}:9094
rule_version_record_limit: "5"
alerting:
enabled: false
```
### Installing plugins
If you want to install a Grafana plugin using the helm chart, you can do so by using the identifier of the plugin, for example `digirich-bubblechart-panel` will install [Bubble Chart](https://grafana.com/grafana/plugins/digrich-bubblechart-panel/).
You can also install a plugin and a specific version by specifying the version and URL of the download file as shown in the example below :
```yaml
plugins:
- digrich-bubblechart-panel
- grafana-clock-panel
## You can also use other plugin download URL, as long as they are valid zip files,
## and specify the name of the plugin as prefix, with an version. Like this:
# - marcusolsson-json-datasource@1.3.24@https://grafana.com/api/plugins/marcusolsson-json-datasource/versions/1.3.24/download
```
Generic documentation about plugins can be found in the [official documentation](https://grafana.com/docs/grafana/latest/administration/plugin-management/).

# kube-state-metrics Helm Chart
Installs the [kube-state-metrics agent](https://github.com/kubernetes/kube-state-metrics).
## Usage
The chart is distributed as an [OCI Artifact](https://helm.sh/docs/topics/registries/) as well as via a traditional [Helm Repository](https://helm.sh/docs/topics/chart_repository/).
- OCI Artifact: `oci://ghcr.io/prometheus-community/charts/kube-state-metrics`
- Helm Repository: `https://prometheus-community.github.io/helm-charts` with chart `kube-state-metrics`
The installation instructions use the OCI registry. Refer to the [`helm repo`]([`helm repo`](https://helm.sh/docs/helm/helm_repo/)) command documentation for information on installing charts via the traditional repository.
### Install Chart
```console
helm install [RELEASE_NAME] oci://ghcr.io/prometheus-community/charts/kube-state-metrics [flags]
```
_See [configuration](#configuration) below._
_See [helm install](https://helm.sh/docs/helm/helm_install/) for command documentation._
### Uninstall Chart
```console
helm uninstall [RELEASE_NAME]
```
This removes all the Kubernetes components associated with the chart and deletes the release.
_See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation._
### Upgrading Chart
```console
helm upgrade [RELEASE_NAME] oci://ghcr.io/prometheus-community/charts/kube-state-metrics [flags]
```
_See [helm upgrade](https://helm.sh/docs/helm/helm_upgrade/) for command documentation._
#### Migrating from stable/kube-state-metrics and kubernetes/kube-state-metrics
You can upgrade in-place:
1. [upgrade](#upgrading-chart) your existing release name using the new chart repository
## Upgrading to v6.0.0
This version drops support for deprecated Pod Security Policy resources.
## Upgrading to v3.0.0
v3.0.0 includes kube-state-metrics v2.0, see the [changelog](https://github.com/kubernetes/kube-state-metrics/blob/release-2.0/CHANGELOG.md) for major changes on the application-side.
The upgraded chart now the following changes:
- Dropped support for helm v2 (helm v3 or later is required)
- collectors key was renamed to resources
- namespace key was renamed to namespaces
## Configuration
See [Customizing the Chart Before Installing](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing). To see all configurable options with detailed comments:
```console
helm show values oci://ghcr.io/prometheus-community/charts/kube-state-metrics
```
### kube-rbac-proxy
You can enable `kube-state-metrics` endpoint protection using `kube-rbac-proxy`. By setting `kubeRBACProxy.enabled: true`, this chart will deploy one RBAC proxy container per endpoint (metrics & telemetry).
To authorize access, authenticate your requests (via a `ServiceAccount` for example) with a `ClusterRole` attached such as:
```yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
name: kube-state-metrics-read
rules:
- apiGroups: [ "" ]
resources: ["services/kube-state-metrics"]
verbs:
- get
```
See [kube-rbac-proxy examples](https://github.com/brancz/kube-rbac-proxy/tree/master/examples/resource-attributes) for more details.

kube-state-metrics is a simple service that listens to the Kubernetes API server and generates metrics about the state of the objects.
The exposed metrics can be found here:
https://github.com/kubernetes/kube-state-metrics/blob/master/docs/README.md#exposed-metrics
The metrics are exported on the HTTP endpoint /metrics on the listening port.
In your case, {{ template "kube-state-metrics.fullname" . }}.{{ template "kube-state-metrics.namespace" . }}.svc.cluster.local:{{ .Values.service.port }}/metrics
They are served either as plaintext or protobuf depending on the Accept header.
They are designed to be consumed either by Prometheus itself or by a scraper that is compatible with scraping a Prometheus client endpoint.
{{- if .Values.kubeRBACProxy.enabled}}
kube-rbac-proxy endpoint protections is enabled:
- Metrics endpoints are now HTTPS
- Ensure that the client authenticates the requests (e.g. via service account) with the following role permissions:
```
rules:
- apiGroups: [ "" ]
resources: ["services/{{ template "kube-state-metrics.fullname" . }}"]
verbs:
- get
```

# Prometheus Node Exporter
Prometheus exporter for hardware and OS metrics exposed by *NIX kernels, written in Go with pluggable metric collectors.
This chart bootstraps a Prometheus [Node Exporter](http://github.com/prometheus/node_exporter) daemonset on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
## Usage
The chart is distributed as an [OCI Artifact](https://helm.sh/docs/topics/registries/) as well as via a traditional [Helm Repository](https://helm.sh/docs/topics/chart_repository/).
- OCI Artifact: `oci://ghcr.io/prometheus-community/charts/prometheus-node-exporter`
- Helm Repository: `https://prometheus-community.github.io/helm-charts` with chart `prometheus-node-exporter`
The installation instructions use the OCI registry. Refer to the [`helm repo`]([`helm repo`](https://helm.sh/docs/helm/helm_repo/)) command documentation for information on installing charts via the traditional repository.
### Install Chart
```console
helm install [RELEASE_NAME] oci://ghcr.io/prometheus-community/charts/prometheus-node-exporter
```
_See [configuration](#configuring) below._
_See [helm install](https://helm.sh/docs/helm/helm_install/) for command documentation._
### Uninstall Chart
```console
helm uninstall [RELEASE_NAME]
```
This removes all the Kubernetes components associated with the chart and deletes the release.
_See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation._
### Upgrading Chart
```console
helm upgrade [RELEASE_NAME] oci://ghcr.io/prometheus-community/charts/prometheus-node-exporter --install
```
_See [helm upgrade](https://helm.sh/docs/helm/helm_upgrade/) for command documentation._
#### 3.x to 4.x
Starting from version 4.0.0, the `node exporter` chart is using the [Kubernetes recommended labels](https://kubernetes.io/docs/concepts/overview/working-with-objects/common-labels/). Therefore you have to delete the daemonset before you upgrade.
```console
kubectl delete daemonset -l app=prometheus-node-exporter
helm upgrade -i prometheus-node-exporter prometheus-community/prometheus-node-exporter
```
If you use your own custom [ServiceMonitor](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/api-reference/api.md#servicemonitor) or [PodMonitor](https://github.com/prometheus-operator/prometheus-operator/blob/main/Documentation/api-reference/api.md#podmonitor), please ensure to upgrade their `selector` fields accordingly to the new labels.
#### From 2.x to 3.x
Change the following:
```yaml
hostRootFsMount: true
```
to:
```yaml
hostRootFsMount:
enabled: true
mountPropagation: HostToContainer
```
## Configuring
See [Customizing the Chart Before Installing](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing). To see all configurable options with detailed comments, visit the chart's [values.yaml](./values.yaml), or run these configuration commands:
```console
helm show values oci://ghcr.io/prometheus-community/charts/prometheus-node-exporter
```
### kube-rbac-proxy
You can enable `prometheus-node-exporter` endpoint protection using `kube-rbac-proxy`. By setting `kubeRBACProxy.enabled: true`, this chart will deploy a RBAC proxy container protecting the node-exporter endpoint.
To authorize access, authenticate your requests (via a `ServiceAccount` for example) with a `ClusterRole` attached such as:
```yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
name: prometheus-node-exporter-read
rules:
- apiGroups: [ "" ]
resources: ["services/node-exporter-prometheus-node-exporter"]
verbs:
- get
```
See [kube-rbac-proxy examples](https://github.com/brancz/kube-rbac-proxy/tree/master/examples/resource-attributes) for more details.
