 ## Installing Kubecost for GKE Autopilot via Helm
 
-Installing Kubecost on a GKE Autopilot cluster is similar to other cloud providers with Helm v3.1+, with a few changes. Autopilot requires the use of [Google Managed Prometheus](/install-and-configure/advanced-configuration/custom-prom/gcp-gmp-integration.md) service, which generates additional costs within your Google Cloud account.
+Installing Kubecost on a GKE Autopilot cluster is similar to other cloud providers with Helm v3.1+, with a few changes. Autopilot restricts privileged containers by default so the kubecost-network-costs container needs to be disabled.
 
-`helm install kubecost/cost-analyzer -n kubecost -f values.yaml`
-
-Your _values.yaml_ files must contain the below parameters. Resources are specified for each section of the Kubecost deployment, and Pod Security Policies are disabled.

-## Turning on Kubelet/cAdvisor scraping via Google Managed Collector
-
-Open the OperatorConfig on your Autopilot Cluster resource for editing:
 
 ```bash
-kubectl -n gmp-public edit operatorconfig config
+helm upgrade --install kubecost --repo https://kubecost.github.io/kubecost/ kubecost --namespace kubecost --create-namespace --values values.yaml
 ```
 
-Add the following collection section to the resource:
+Your _values.yaml_ files must contain the below parameters.
 
 ```yaml
-apiVersion: monitoring.googleapis.com/v1
-kind: OperatorConfig
-metadata:
-  namespace: gmp-public
-  name: config
-collection:
-  kubeletScraping:
-    interval: 30s
+global:
+  clusterId: "clusterName" # used for display in Kubecost UI
+networkCosts:
+  enabled: false
 ```
 
-Save the file and close the editor. After a short time, the Kubelet metric endpoints will be scraped and the metrics become available for querying in Managed Service for Prometheus.
