How to use the cost insights feature of a registered cluster

Grant permissions to access the bill data of the ACK cluster.

• ACK managed cluster: The system automatically grants the required permissions. After authorization is complete, the system creates the AliyunCSManagedCostRole role. Managed Service for Prometheus then assumes this role to access your billing data from Expenses and Costs for cost analysis.

  Alternatively, click the RAM Quick Authorization link. On the RAM Quick Authorization page, click Confirm.

• ACK dedicated cluster:

  Authorization steps

  1. On the Cost Insights page, click KubernetesWorkerRole-***.

  2. On the Permissions tab of the RAM role details page, click k8sWorkerRole**** in the Policies column.

  3. On the policy details page, click the Policy Content tab, and then click Modify Policy Document.

  4. In the code editor, add the following authorization rules to the Statement field. After modifying the policy, click Modify Basic Information and then click OK.

             {
                 "Action": [
                     "bssapi:QueryInstanceBill",
                     "bssapi:DescribeInstanceBill"
                 ],
                 "Resource": "*",
                 "Effect": "Allow"
             },
             {
                 "Action": [
                     "ecs:DescribeDisks",
                     "ecs:DescribeSpotPriceHistory",
                     "ecs:DescribeInstances",
                     "ecs:DescribePrice"
                 ],
                 "Resource": "*",
                 "Effect": "Allow"
             },
             {
                 "Action": [
                     "eci:DescribeContainerGroupPrice"
                 ],
                 "Resource": "*",
                 "Effect": "Allow"
             }

     Note

     Separate multiple policy statements with a comma (,).

In Account A where the registered cluster resides, install Managed Service for Prometheus. For more information, see Connect a registered cluster to Managed Service for Prometheus.

In Account A where the registered cluster resides, configure the AckRegisteredClusterId parameter for the ack-cost-exporter component. Set the parameter to the clusterId of the ACK cluster in Account B.

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

2. On the Clusters page, click the name of the target cluster, and then in the left navigation bar, select Applications > Helm.

   If a release of ack-cost-exporter already exists on the Helm page, delete the release and then follow the subsequent steps to reinstall it.

3. In the left navigation bar of the cluster management page, select Operations > Add-ons.

4. On the Add-ons page, click the Logs and Monitoring tab, find the ack-cost-exporter add-on, and click Install in the lower-right corner.

5. On the Install ack-cost-exporter page, set registeredAckClusterId to the clusterId of the cluster in Account B, and then click OK.
