In this post, I’m going to install kube-prometheus on AKS. The process is clearly documented at the kube-prometheus Github page. Here, I’m just going to use the ‘quickstart’ and later I plan to cover other topics such as ingress and customization.
Pre-requisites:
- A Kubernetes cluster. In this example I’m using AKS, but similar steps could be done with other providers or with self-hosted Kubernetes.
- kubectl
Helpful links:
Do this:
Clone the Github repo.
git clone https://github.com/prometheus-operator/kube-prometheus.git
Create the monitoring stack.
# Create the namespace and CRDs, and then wait for them to be available before creating the remaining resources # Note that due to some CRD size we are using kubectl server-side apply feature which is generally available since kubernetes 1.22. # If you are using previous kubernetes versions this feature may not be available and you would need to use kubectl create instead. kubectl apply --server-side -f manifests/setup kubectl wait \ --for condition=Established \ --all CustomResourceDefinition \ --namespace=monitoring kubectl apply -f manifests/
Confirm your pods are running.

Connect to Grafana using a port-forward.
kubectl --namespace monitoring port-forward svc/grafana 3000
Access http://localhost:3000 with a browser. The default Grafana login is admin:admin and you’ll be prompted to change that upon first login.
There’s lots of great data surfaced in the Grafana dashboards; have a look around!
