Is this a BUG REPORT or FEATURE REQUEST? (choose one):

Version of Helm and Kubernetes:

Helm:
Version{SemVer:"v2.10.0", GitCommit:"9ad53aac42165a5fadc6c87be0dea6b115f93090", GitTreeState:"clean"}
Kubernetes:

Which chart:
[stable/grafana]

What happened:
I'm trying to setup grafana to load charts from dashboards folder in chart as per documentation. Created dashboard folder in my chart folder and put sample redis.json file there. In values.yaml configured following:

dashboardProviders:
  dashboardproviders.yaml:
    apiVersion: 1
    providers:
    - name: 'default'
      orgId: 1
      folder: ''
      type: file
      disableDeletion: false
      editable: true
      options:
        path: /var/lib/grafana/dashboards/default

dashboards:
  default:
    redis:
      file: dashboards/redis.json
    prometheus-stats:
      gnetId: 2
      revision: 2
      datasource: Prometheus
#    local-dashboard:
#      url: https://example.com/repository/test.json
#    local-dashboard-base64:
#      url: https://example.com/repository/test-b64.json
#      b64content: true`

When I deploy grafana prometheus-stats dashboard is loaded, but redis one no. I see that chart created config map with following contents. Also in container file redis.json was copied to /var/lib/grafana/dashboards/default, but it is empty. Does it mean it was not able to parse json or something like that, as there is empty value?
If I run
helm install --dry-run --debug --name grafana --namespace monitoring -f values.yaml stable/grafana
there is no errors thrown.

apiVersion: v1
kind: ConfigMap
metadata:
  name: grafana-dashboards-default
  labels:
    app: grafana
    chart: grafana-3.0.1
    release: grafana
    heritage: Tiller
    dashboard-provider: default
data:
  redis.json:
    ""

What you expected to happen:

Expect dashboard to be imported

How to reproduce it (as minimally and precisely as possible):

Using helm install command and modifying values.yaml file with above values
helm install --name grafana --namespace monitoring -f values.yaml stable/grafana

This is still an issue for me. All my custom dashboards are empty in the container. Can someone please give instructions how to import dashboards?

There is a ` at the end of the default dashboards provider. Is this a typo?

Yep @maorfr sorry, this is from formatting here

It seems to work for me. I have the same dashboardProviders section. In addition, I have the following key set:

dashboardsConfigMaps:
  default: "grafana-dashboard"

The value grafana-dashboard is the name of a ConfigMap in the same namespace. The content looks like this:

apiVersion: v1
data:
  gain-dashboard.json: "cut out for brevity" 
kind: ConfigMap
metadata:
  creationTimestamp: "2019-04-01T08:14:07Z"
  name: grafana-dashboard
  namespace: monitoring
  resourceVersion: "1039344"
  selfLink: /api/v1/namespaces/monitoring/configmaps/grafana-dashboard
  uid: 1ec73781-5456-11e9-bfc8-42010a9c00b0

After deploying, I can see the following on the grafana container:

$ kubectl -n monitoring exec -it grafana-68cddfcf4-kq9s5 ls /var/lib/grafana/dashboards/default
gain-dashboard.json

The content of gain-dashboard.json corresponds to the content loaded into the ConfigMap.

In addition is the the dashboardProviders file in the following location:

$ kubectl -n monitoring exec -it grafana-68cddfcf4-kq9s5 ls /etc/grafana/provisioning/dashboards
dashboardproviders.yaml

I also configured a datasource but I omit that as it does not seem to be your issue.

Hi @frosenberg , thanks for helping out here. But it seems in your case you are actually loading dashboard from config map? My intention was to load from file in chart subfolder "dashboards", as per readme in chart repo. I've highlighted relevant section

There are a few methods to import dashboards to Grafana. Below are some examples and explanations as to how to use each method:

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**
