Grafana Deployment and Service YAML for Kubernetes

The following YAML files define how to deploy Grafana on a Kubernetes cluster and expose it through a Service.

Grafana Deployment (grafana-deploy.yaml)

apiVersion: apps/v1
kind: Deployment
metadata:
  name: grafana-core
  namespace: kube-system
  labels:
    app: grafana
    component: core
spec:
  replicas: 1
  selector:
    matchLabels:
      app: grafana
      component: core
  template:
    metadata:
      labels:
        app: grafana
        component: core
    spec:
      containers:
      - image: grafana/grafana:4.2.0
        name: grafana-core
        imagePullPolicy: IfNotPresent
        # env:
        resources:
          keep request = limit to keep this container in guaranteed class
          limits:
            cpu: 100m
            memory: 100Mi
          requests:
            cpu: 100m
            memory: 100Mi
        env:
          # The following env variables set up basic auth twith the default admin user and admin password.
          - name: GF_AUTH_BASIC_ENABLED
            value: "true"
          - name: GF_AUTH_ANONYMOUS_ENABLED
            value: "false"
          - name: GF_AUTH_ANONYMOUS_ORG_ROLE
            value: Admin
          does not really work, because of template variables in exported dashboards:
          - name: GF_DASHBOARDS_JSON_ENABLED
            value: "true"
        readinessProbe:
          httpGet:
            path: /login
            port: 3000
          initialDelaySeconds: 30
          timeoutSeconds: 1
        volumeMounts:
          - name: grafana-persistent-storage
            mountPath: /var
      volumes:
        - name: grafana-persistent-storage
          emptyDir: {}

Grafana Service (grafana-svc.yaml)

apiVersion: v1
kind: Service
metadata:
  name: grafana
  namespace: kube-system
  labels:
    app: grafana
    component: core
spec:
  type: NodePort
  ports:
    - port: 3000
  selector:
    app: grafana
    component: core
