After Grafana is installed as per kube-prometheus-stack there is a way to import saved before dashboards via k8s-sidecar container which is running on the same pod as Grafana itself:

kubectl get -n monitoring pod | grep grafana
prometheus-grafana-57f78bfdb-9xq96                        2/2     Running   0          32m

kubectl describe pod prometheus-grafana-57f78bfdb-9xq96 -n monitoring | egrep -A 25 "^Containers:" | grep "Image:"
    Image:          quay.io/kiwigrid/k8s-sidecar:1.10.7
    Image:          grafana/grafana:7.4.5

kubectl describe pod prometheus-grafana-57f78bfdb-9xq96 -n monitoring | grep -A 17 "grafana-sc-dashboard:"
    Container ID:   containerd://088f282a72b2bf512a2dcaf5040658fca6b557d2406b0d8c7b1f5dc52284ac0d

High level plan is:

  • Export desired version of Grafana dashboard and save it as json-file
  • Prepare ConfigMap based on exported before json-formatted dashboard
  • Apply ConfigMap to existing monitoring namespace k8s-sidecar container to import it to Grafana

Export desired grafana dashboard(s)

Firstly prepare version of dashboard which you want to save for future, select Share -> Export -> Save to file and save it as grafana-dashboard-k3s.json (as example):


Prepare ConfigMap yaml-file

Based on exported dashboard as json-file ConfigMap yaml-file should be prepared. It should look like:

cat > grafana-dashboard-k3s.yaml
apiVersion: v1
kind: ConfigMap
  name: grafana-dashboard-k3s
    grafana_dashboard: "1"
  namespace: monitoring
  grafana-dashboard-k3s.json: |
      "annotations": {
        "list": [
            "builtIn": 1,
            "datasource": "-- Grafana --",
            "enable": true,
            "hide": true,
            "iconColor": "rgba(0, 211, 255, 1)",
            "name": "Annotations & Alerts",
            "type": "dashboard"
      "description": "Monitor a Kubernetes cluster using Prometheus TSDB.  Shows overall cluster CPU / Memory / Disk usage as well as individual pod statistics. ",
      "editable": true,
      "gnetId": 162,
      "graphTooltip": 1,
      "id": 25,
      "timezone": "browser",
      "title": "Kubernetes cluster monitoring (via Prometheus)",
      "uid": "hgN5WikRz",
      "version": 11

As example - grafana-dashboard-k3s.yaml, it’s based on kubernetes-cluster-dashboard.json from Cluster Monitoring stack for ARM / X86-64 platforms.

Apply ConfigMap to monitoring namespace

After applying prepared configmap to monitoring namespace you should see the following logs for grafana-sc-dashboard container:

kubectl -f grafana-dashboard-router.yaml apply

kubectl -n monitoring logs prometheus-grafana-57f78bfdb-9xq96 grafana-sc-dashboard
[2021-03-28 07:46:08] Working on configmap monitoring/grafana-dashboard-k3s
[2021-03-28 07:46:08] File in configmap grafana-dashboard-k3s.json ADDED

Straight after that added dashboard should be visible in Grafana under Dashboards -> Manage.
