Container Service for Kubernetes:Enable cost insights

Billing

• Cost insights metrics

  The cost insights feature generates basic metrics from data such as bills and cloud resource pricing, and reports them to Managed Service for Prometheus. Modifying default configurations, such as storage retention periods, may incur additional costs.

• Cost tag configuration By default, the cost insights feature filters data using cost allocation tags. To ensure Cost Insights can retrieve billing data or node pool analytics:

  1. Enable Cost allocation tags in the Expenses and Costs console.

  2. Enable the ack.aliyun.com and ack.alibabacloud.com/nodepool-id tags in the Cost allocation tags settings.

Enable cost insights

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

2. On the Clusters page, find the cluster you want and click its name. In the left-side pane, choose Cost Suite > Cost Insights.

3. Assign the AliyunCSManagedCostRole Resource Access Management (RAM) role to your cluster and install the ack-cost-exporter component.

   1. Authorize your ACK cluster to access your billing data in Billing Management

      • ACK managed clusters: The system automatically grants the required permissions. After the authorization is complete, the system automatically creates the AliyunCSManagedCostRole role. Managed Service for Prometheus assumes the RAM role to access your billing data in Expenses and Costs.

        You can also Authorize on the RAM Quick Authorization page.

      • ACK dedicated clusters:
