## Extra environment variables that will be pass onto deployment pods
##
## to provide grafana with access to CloudWatch on AWS EKS:
## 1. create an iam role of type "Web identity" with provider oidc.eks.* (note the provider for later)
## 2. edit the "Trust relationships" of the role, add a line inside the StringEquals clause using the
## same oidc eks provider as noted before (same as the existing line)
## also, replace NAMESPACE and prometheus-operator-grafana with the service account namespace and name
##
##  "oidc.eks.us-east-1.amazonaws.com/id/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:sub": "system:serviceaccount:NAMESPACE:prometheus-operator-grafana",
##
## 3. attach a policy to the role, you can use a built in policy called CloudWatchReadOnlyAccess
## 4. use the following env: (replace 123456789000 and iam-role-name-here with your aws account number and role name)
##
## env:
##   AWS_ROLE_ARN: arn:aws:iam::123456789000:role/iam-role-name-here
##   AWS_WEB_IDENTITY_TOKEN_FILE: /var/run/secrets/eks.amazonaws.com/serviceaccount/token
##   AWS_REGION: us-east-1
##
## 5. uncomment the EKS section in extraSecretMounts: below

# Grafana Helm Chart

* Installs the web dashboarding system [Grafana](http://grafana.org/)

## Get Repo Info

```console
helm repo add grafana https://grafana.github.io/helm-charts
helm repo update
```

_See [helm repo](https://helm.sh/docs/helm/helm_repo/) for command documentation._

## Installing the Chart

To install the chart with the release name `my-release`:

```console
helm install my-release grafana/grafana
```

### Example ingress with path

With grafana 6.3 and above
```yaml
grafana.ini:
  server:
    serve_from_sub_path: true
ingress:
  enabled: true
  hosts:
    - "monitoring.example.com"
  path: "/grafana"
```

### Example of extraVolumeMounts

Volume can be type persistentVolumeClaim or hostPath but not both at same time.
If none existingClaim or hostPath argument is givent then type is emptyDir.

```yaml
- extraVolumeMounts:
  - name: plugins
    mountPath: /var/lib/grafana/plugins
    subPath: configs/grafana/plugins
    existingClaim: existing-grafana-claim
    readOnly: false
  - name: dashboards
    mountPath: /var/lib/grafana/dashboards
    hostPath: /usr/shared/grafana/dashboards
    readOnly: false
```

## Import dashboards


      json: |
        {
          "annotations":

          "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
      gnetId: 2
      revision: 2
      datasource: Prometheus
    local-dashboard:
      url: https://raw.githubusercontent.com/user/repository/master/dashboards/dashboard.json
```

## BASE64 dashboards

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

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
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.

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.


```yaml
datasources:
 datasources.yaml:
   apiVersion: 1
   datasources:
      # <string, required> name of the datasource. Required
    - name: Graphite
      # <string, required> datasource type. Required
      type: graphite
      # <string, required> access mode. proxy or direct (Server or Browser in the UI). Required
      access: proxy
      # <int> org id. will default to orgId 1 if not specified
      orgId: 1
      # <string> url
      url: http://localhost:8080
      # <string> database password, if used
      password:
      # <string> database user, if used
      user:
      # <string> database name, if used
      database:
      # <bool> enable/disable basic auth
      basicAuth:
      # <string> basic auth username
      basicAuthUser:
      # <string> basic auth password
      basicAuthPassword:
      # <bool> enable/disable with credentials headers
      isDefault:
      # <map> fields that will be converted to json and stored in json_data
      jsonData:
         graphiteVersion: "1.1"
         tlsAuth: true
         tlsAuthWithCACert: true
      # <string> json object of data that will be encrypted.
      secureJsonData:
        tlsCACert: "..."
        tlsClientCert: "..."
        tlsClientKey: "..."
      version: 1
      # <bool> allow users to edit datasources from the UI.
      editable: false
```

## 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.


```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-2
    # default org_id: 1
```

## 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


In grafana.ini:

```yaml
grafana.ini:
  [auth.generic_oauth]
  enabled = true
  client_id = $__file{/etc/secrets/auth_generic_oauth/client_id}

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:

  - 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

```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/docs/remote_rendering_using_docker.md)

```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
