Enable cost insights

Cost dimensions

You can analyze costs by:

• Cluster

• Namespace

• Node pool

• Application (Deployment, StatefulSet, DaemonSet, Job, CronJob)

Billing

Enable cost insights

1. Log on to the ACK console. In the left navigation pane, click Clusters.

2. On the Clusters page, click the name of your cluster. In the left navigation pane, click Cost Suite > Cost Insights.

3. Authorize your cluster to access billing data.

   Authorization differs by cluster type:

   1. Grant billing data access

      • ACK managed clusters

        The system automatically creates the AliyunCSManagedCostRole RAM role. Prometheus assumes this role to access your billing data.

        Or authorize from the RAM Quick Authorization page.

      • ACK dedicated clusters

        Add billing permissions to the worker role policy:
