Deploy Grafana

We are now going to install Grafana. For this example, we are primarily using the Grafana defaults, but we are overriding several parameters. As with Prometheus, we are setting the storage class to gp2, admin password, configuring the datasource to point to Prometheus and creating an external load balancer for the service.

Create YAML file called grafana.yaml with following commands:

mkdir ${HOME}/environment/grafana

cat << EoF > ${HOME}/environment/grafana/grafana.yaml
datasources:
  datasources.yaml:
    apiVersion: 1
    datasources:
    - name: Prometheus
      type: prometheus
      url: http://prometheus-server.prometheus.svc.cluster.local
      access: proxy
      isDefault: true
EoF

kubectl create namespace grafana

helm install grafana grafana/grafana \
    --namespace grafana \
    --set persistence.storageClassName="gp2" \
    --set persistence.enabled=true \
    --set adminPassword='EKS!sAWSome' \
    --values ${HOME}/environment/grafana/grafana.yaml \
    --set service.type=LoadBalancer

Run the following command to check if Grafana is deployed properly:

kubectl get all -n grafana

You should see similar results. They should all be Ready and Available

It can take several minutes before the ELB is up, DNS is propagated and the nodes are registered.

You can get Grafana ELB URL using this command. Copy & Paste the value into browser to access Grafana web UI.

export ELB=$(kubectl get svc -n grafana grafana -o jsonpath='{.status.loadBalancer.ingress[0].hostname}')

echo "http://$ELB"

When logging in, use the username admin and get the password hash by running the following:

kubectl get secret --namespace grafana grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo
