Documentation Grafana Agent Grafana Agent Operator Installing Grafana Agent Operator with Helm

Installing Grafana Agent Operator with Helm

In this guide you’ll learn how to deploy the Grafana Agent Operator into your Kubernetes cluster using the grafana-agent-operator Helm chart.

Note: Agent Operator is currently in beta and its custom resources are subject to change as the project evolves. It currently supports the metrics and logs subsystems of Grafana Agent. Integrations and traces support is coming soon.

By the end of this guide, you’ll have deloyed Agent Operator into your cluster.

Prerequisites

Before you begin, make sure that you have the following available to you:

• A Kubernetes cluster
• The kubectl command-line client installed and configured on your machine
• The helm command-line client installed and configured on your machine

Install Agent Operator Helm Chart

In this step you’ll install the grafana-agent-operator Helm chart into your Kubernetes cluster. This will install the latest version of Agent Operator and its Custom Resource Definitions (CRDs). By default the chart will configure the operator to maintain a Service that allows you scrape kubelets using a ServiceMonitor.

Begin by adding and updating the grafana Helm chart repo:

bash Copy

helm repo add grafana https://grafana.github.io/helm-charts
helm repo update

Next, install the chart:

bash Copy

helm install my-release grafana/grafana-agent-operator

Replace my-release with your desired release name.

If you want to modify the default parameters, you can create a values.yaml file and pass it in to helm install:

bash Copy

helm install my-release grafana/grafana-agent-operator -f values.yaml

A list of configurable template parameters can be found in the Helm chart repository.

If you want to deploy Agent Operator into a namespace other than default, use the -n flag:

bash Copy

helm install my-release grafana/grafana-agent-operator -f values.yaml -n my-namespace

Once you’ve successfully deployed the Helm release, confirm that Agent Operator is up and running:

bash Copy

kubectl get pod
kubectl get svc

You should see an Agent Operator Pod in RUNNING state, and a kubelet Service.

Conclusion

With Agent Operator up and running, you can move on to setting up a GrafanaAgent custom resource. This will discover MetricsInstance and LogsInstance custom resources and endow them with Pod attributes (like requests and limits) defined in the GrafanaAgent spec. To learn how to do this, please see Custom Resource Quickstart.
