Metering can correlate cluster usage information with AWS detailed billing information, attaching a dollar amount to resource usage. For clusters running in EC2, you can enable this by modifying the example aws-billing.yaml file below.

apiVersion: metering.openshift.io/v1
kind: MeteringConfig
metadata:
  name: "operator-metering"
spec:
  openshift-reporting:
    spec:
      awsBillingReportDataSource:
        enabled: true
        # Replace these with where your AWS billing reports are
        # stored in S3.
        bucket: "<your-aws-cost-report-bucket>" (1)
        prefix: "<path/to/report>"
        region: "<your-buckets-region>"

  reporting-operator:
    spec:
      config:
        aws:
          secretName: "<your-aws-secret>" (2)

  presto:
    spec:
      config:
        aws:
          secretName: "<your-aws-secret>" (2)

  hive:
    spec:
      config:
        aws:
          secretName: "<your-aws-secret>" (2)

To enable AWS billing correlation, first ensure the AWS Cost and Usage Reports are enabled. For more information, see Turning on the AWS Cost and Usage Report in the AWS documentation.

1 Update the bucket, prefix, and region to the location of your AWS Detailed billing report.
2 All secretName fields should be set to the name of a secret in the metering namespace containing AWS credentials in the data.aws-access-key-id and data.aws-secret-access-key fields. See the example secret file below for more details.
apiVersion: v1
kind: Secret
metadata:
  name: <your-aws-secret>
data:
  aws-access-key-id: "dGVzdAo="
  aws-secret-access-key: "c2VjcmV0Cg=="

To store data in S3, the aws-access-key-id and aws-secret-access-key credentials must have read and write access to the bucket. For an example of an IAM policy granting the required permissions, see the aws/read-write.json file below.

        }
    ]
}
1 Replace operator-metering-data with the name of your bucket.

This can be done either pre-installation or post-installation. Disabling it post-installation can cause errors in the reporting-operator.
