Get started with Kubernetes platform monitoring

This page provides instructions for deploying the Dynatrace Operator for Kubernetes platform monitoring.

Use cases

If you’re looking to gain deeper insights into your Kubernetes environment, check out the deployment overview to learn about Application observability and Full-Stack observability. You can further expand your Kubernetes observability on Log Analytics, Digital Experience, and Application Security.

Before you begin

Before installing Dynatrace on your Kubernetes cluster, ensure that you meet the following requirements:

Your kubectl CLI is connected to the Kubernetes cluster that you want to monitor.
You have sufficient privileges on the monitored cluster to run kubectl or oc commands.

Cluster setup and configuration

You must allow egress for Dynatrace pods (default: Dynatrace namespace) to your Dynatrace environment URL.
For OpenShift Dedicated, you need the cluster-admin role.
Helm installation Use Helm version 3.

Supported versions

See supported Kubernetes/OpenShift platform versions and distributions.

Installation options

Choose one of the installation methods that best suits your needs.

Helm

Manifest

Helm

Dynatrace Operator version 0.8.0+

Install Dynatrace Operator

The following command works for both default installations and installations using an OCI registry.
```
helm install dynatrace-operator oci://public.ecr.aws/dynatrace/dynatrace-operator \
   --set "csidriver.enabled=false" \
   --create-namespace \
   --namespace dynatrace \
   --atomic \
```
When upgrading your Kubernetes observability setup to include application monitoring, we recommend that you install the CSI driver for improved efficiency. If you plan to expand towards cloud-native full-stack observability, installation of the CSI driver becomes mandatory.

When upgrading your Kubernetes observability setup to include application monitoring, we recommend that you install the CSI driver for improved efficiency. If you plan to expand towards cloud-native full-stack observability, installation of the CSI driver becomes mandatory.
Edit the values.yaml sample from GitHub, and then run the install command, passing the YAML file as an argument:
```
helm install dynatrace-operator oci://public.ecr.aws/dynatrace/dynatrace-operator \
   --create-namespace \
   --namespace dynatrace \
   --atomic \
   -f values.yaml
```
If installCRD is set to false, you need to create the custom resource definition manually before starting the Helm installation:
```
kubectl apply -f https://github.com/Dynatrace/dynatrace-operator/releases/download/v1.4.1/dynatrace-operator-crd.yaml
```
Create secret for access token

Create a secret named dynakube for the Dynatrace Operator token obtained in Tokens and permissions required.
```
kubectl -n dynatrace create secret generic dynakube --from-literal="apiToken=<OPERATOR_TOKEN>"
```

Create your DynaKube custom resource file.

You can review the available parameters or how-to guides, and adapt the DynaKube custom resource according to your requirements.

  # Dynatrace apiUrl including the /api path at the end.
  # Replace 'ENVIRONMENTID' with your environment ID.

        memory: 1.5Gi

Apply the DynaKube custom resource

Run the command below to apply the DynaKube custom resource, making sure to replace <your-DynaKube-CR> with your actual DynaKube custom resource file name. A validation webhook will provide helpful error messages if there's a problem.
```
kubectl apply -f <your-DynaKube-CR>.yaml
```

optional Verify deployment

Verify that your DynaKube is running and all pods in your Dynatrace namespace are running and ready.

> kubectl get dynakube -n dynatrace
NAME         APIURL                                          STATUS     AGE
dynakube     https://<ENVIRONMENTID>.live.dynatrace.com/api  Running    45s

In this DynaKube configuration, you should see the following pods:

> kubectl get pods -n dynatrace
NAME                                  READY   STATUS    RESTARTS        AGE

Manifest

Create a dynatrace namespace
```
kubectl create namespace dynatrace
```

Install Dynatrace Operator

kubectl apply -f https://github.com/Dynatrace/dynatrace-operator/releases/download/v1.4.1/kubernetes.yaml

Run the following command to see when Dynatrace Operator components finish initialization:

kubectl -n dynatrace wait pod --for=condition=ready --selector=app.kubernetes.io/name=dynatrace-operator,app.kubernetes.io/component=webhook --timeout=300s

Create secret for access token

Create a secret named dynakube for the Dynatrace Operator token obtained in Tokens and permissions required.
```
kubectl -n dynatrace create secret generic dynakube --from-literal="apiToken=<OPERATOR_TOKEN>"
```

Create your DynaKube custom resource YAML file.

You can review the available parameters or how-to guides, and adapt the DynaKube custom resource according to your requirements.
