To forward CoreWeave Kubernetes Service (CKS) metrics to an external system, deploy the Prometheus Agent inside your CKS cluster and configure it to use remote-write.
CKS clusters deployed before July 7, 2025 have Prometheus Operator pre-installed.CKS clusters deployed after July 7, 2025 don’t have Prometheus Operator pre-installed. Clusters deployed after this date must install Prometheus Operator before proceeding with the following steps.
To deploy the Prometheus Agent in your CKS cluster, complete the following steps:
  1. Choose a namespace to deploy the Prometheus Agent in. You can deploy the Prometheus Agent to an existing namespace, or create a new namespace with kubectl. To create a new namespace, replace [NAMESPACE-NAME] with your chosen namespace and run: 
    kubectl create namespace "[NAMESPACE-NAME]"
  2. Configure the Prometheus Agent CustomResource YAML file with your remote-write destination, as in the following example:
    sample-prometheus-agent.yaml
    apiVersion: monitoring.coreos.com/v1alpha1
kind: PrometheusAgent
metadata:
  name: my-prom-agent
  namespace: "[NAMESPACE-NAME]"
spec:
  remoteWrite:
    - url: "https://example-url/api/v1/write"
      ...
    For more information about remoteWrite configurations, see the Prometheus Operator API reference.
  3. To deploy the Prometheus Agent to your CKS cluster, replace sample-prometheus-agent.yaml with the appropriate filename and run: 
    kubectl apply -f sample-prometheus-agent.yaml
    Metrics generated within your CKS cluster now remote-write to your specified destination.
