Lab 01, Exercise 04: Install Prometheus and Grafana
Objective: Install Prometheus and Grafana into Kubernetes cluster.
Step 1: Install Prometheus and Grafana
First, navigate to this exercise’s directory:
cd ~/service-mesh-training/exercises/lab-01/04-install-prometheus-and-grafana/
Install Prometheus with kubectl apply:
kubectl apply -f files/prometheus
configmap/prometheus-server-conf created
clusterrole.rbac.authorization.k8s.io/prometheus created
clusterrolebinding.rbac.authorization.k8s.io/prometheus created
service/prometheus created
service/grafana created
statefulset.apps/prometheus-statefulset created
daemonset.apps/prometheus-statsd created
Install Grafana with kubectl apply:
kubectl apply -f files/metrics-server
clusterrole.rbac.authorization.k8s.io/system:aggregated-metrics-reader created
clusterrolebinding.rbac.authorization.k8s.io/metrics-server:system:auth-delegator created
rolebinding.rbac.authorization.k8s.io/metrics-server-auth-reader created
apiservice.apiregistration.k8s.io/v1beta1.metrics.k8s.io created
serviceaccount/metrics-server created
deployment.extensions/metrics-server created
service/metrics-server created
clusterrole.rbac.authorization.k8s.io/system:metrics-server created
clusterrolebinding.rbac.authorization.k8s.io/system:metrics-server created
Step 2: Verify installation
With kubectl to ensure the pods are running:
$ kubectl get pods

Click on the Grafana tab in Instruqt and you should see the Grafana user interface:
The default credentials are username admin and password admin.
We won’t be using it much for this workshop, but you can also see the Prometheus dashboard on that tab:
