How to import custom dashboards to grafana using helm
Solution 1
In the latest version of kube-prometheus-stack
chart in 2021, According to this answer on github, You should just create a configmap with dashboard data and right labels and it will be checked by sidecar in grafana pod.
Example:
apiVersion: v1
kind: ConfigMap
metadata:
name: grafana-dashboards-custom-1
namespace: monitoring
labels:
grafana_dashboard: "1"
prometheus: my-value
release: prometheus
data:
app-status.json: |-
{
"annotations": {
"list": [
{
prometheus: my-value
comes from this helm chart value:
prometheus:
prometheusSpec:
serviceMonitorSelector:
matchLabels:
prometheus: my-value
Solution 2
I partially figured it out. I can load dashboards from a configmap. Not from separate json files yet but it'a progress.
For anyone interested I put this on my github page: https://github.com/tretos53/notes/blob/master/Grafana/Readme.MD
Solution 3
You can find a good example of how to do this in the charts for prometheus-operator here:
https://github.com/helm/charts/tree/master/stable/prometheus-operator/templates/grafana
It is a ConfigMapList that gets all JSONs from a given directory and stores them into ConfigMaps which are read by Grafana.
{{- $files := .Files.Glob "dashboards/*.json" }}
{{- if $files }}
apiVersion: v1
kind: ConfigMapList
items:
{{- range $path, $fileContents := $files }}
{{- $dashboardName := regexReplaceAll "(^.*/)(.*)\\.json$" $path "${2}" }}
- apiVersion: v1
kind: ConfigMap
metadata:
name: {{ printf "%s-%s" (include "prometheus-operator.fullname" $) $dashboardName | trunc 63 | trimSuffix "-" }}
namespace: {{ template "prometheus-operator.namespace" . }}
labels:
{{- if $.Values.grafana.sidecar.dashboards.label }}
{{ $.Values.grafana.sidecar.dashboards.label }}: "1"
{{- end }}
app: {{ template "prometheus-operator.name" $ }}-grafana
{{ include "prometheus-operator.labels" $ | indent 6 }}
data:
{{ $dashboardName }}.json: {{ $.Files.Get $path | toJson }}
{{- end }}
{{- end }}
Mind that the size of a ConfigMap might be limited: https://stackoverflow.com/a/53015758/4252480

I'm trying to understand helm and I wonder if someone could ELI5 to me something or help me with something.
So i did run below:
helm repo add coreos https://s3-eu-west-1.amazonaws.com/coreos-charts/stable/
Then I installed kube-prometheus by using below:
helm install coreos/kube-prometheus --name kube-prometheus -f values.yaml --namespace monitoringtest
Everything works fine but I'm trying to add some custom dashboards from json files and I'm struggling to understand how to do it.
I was following this:
https://blogcodevalue.wordpress.com/2018/09/16/automate-grafana-dashboard-import-process/
In my values.yaml I added below
serverDashboardConfigmaps: - example-dashboards
I understand that if I do:
helm upgrade --install kube-prometheus -f values.yaml --namespace monitoringtest coreos/kube-prometheus
That should cause grafana to pickup a below configmap called
example-dashboards
and load *.json files fromcustom-dashboards
folder.apiVersion: v1 kind: ConfigMap metadata: name: example-dashboards data: {{ (.Files.Glob "custom-dashboards/*.json").AsConfig | indent 2 }} # Or # # data: # custom-dashboard.json: |- # {{ (.Files.Get "custom.json") | indent 4 }} # # The filename (and consequently the key under data) must be in the format `xxx-dashboard.json` or `xxx-datasource.json` # for them to be picked up.
Now two questions:
How do I add above configmap to this helm release?
Where is this
custom-dashboards
folder located? Is it on my laptop and then is send to grafana?Do I need to copy all of
https://s3-eu-west-1.amazonaws.com/coreos-charts/stable/
onto my laptop?Sorry for explaining everything but I'm just trying to understand this.

Valentin Gazzola over 3 yearsFor people from the future:
apiVersion: v1 kind: ConfigMap metadata: name: custom-dashboards data: rpi-dashboard.json: |- {{ .Files.Get "dashboards/rpi-dashboard.json" | indent 4}}
with the path being relative to your helm chart
