The Datadog Operator is an open source Kubernetes Operator that enables you to deploy and configure the Datadog Agent in a Kubernetes environment. This guide describes how to use the Operator to deploy the Datadog Agent.
Prerequisites
- Kubernetes v1.20.X+
- Helm for deploying the Datadog Operator
- The Kubernetes command-line tool, kubectl, for installing the Datadog Agent
Installation and deployment
- Install the Datadog Operator with Helm:
helm repo add datadog https://helm.datadoghq.com
helm install my-datadog-operator datadog/datadog-operator
- Create a Kubernetes secret with your API and application keys:
kubectl create secret generic datadog-secret --from-literal api-key=<DATADOG_API_KEY> --from-literal app-key=<DATADOG_APP_KEY>
Replace <DATADOG_API_KEY>
and <DATADOG_APP_KEY>
with your Datadog API and application keys.
- Create a
datadog-agent.yaml
file with the spec of your DatadogAgent
deployment configuration. The following sample configuration enables metrics, logs, and APM:
apiVersion: datadoghq.com/v2alpha1
kind: DatadogAgent
metadata:
name: datadog
spec:
global:
credentials:
apiSecret:
secretName: datadog-secret
keyName: api-key
appSecret:
secretName: datadog-secret
keyName: app-key
features:
apm:
enabled: true
logCollection:
enabled: true
- Deploy the Datadog Agent:
kubectl apply -f /path/to/your/datadog-agent.yaml
Validation
Use kubectl get daemonset
and kubectl get pod -owide
to validate your installation.
In a cluster with two worker Nodes, you should see Agent Pods created on each Node:
$ kubectl get daemonset
NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE SELECTOR AGE
datadog-agent 2 2 2 2 2 <none> 5m30s
$ kubectl get pod -owide
NAME READY STATUS RESTARTS AGE IP NODE
agent-datadog-operator-d897fc9b-7wbsf 1/1 Running 0 1h 10.244.2.11 kind-worker
datadog-agent-k26tp 1/1 Running 0 5m59s 10.244.2.13 kind-worker
datadog-agent-zcxx7 1/1 Running 0 5m59s 10.244.1.7 kind-worker2
Cleanup
The following commands delete all Kubernetes resources created in this guide:
kubectl delete datadogagent datadog
helm delete my-datadog-operator
