AWS CUR 2 Export Setup for Spotter

AWS CUR 2 Export Setup

This guide describes how to configure AWS Cost and Usage Report (CUR) 2.0 export for integration with Spotter.

1. Create Data Export

Navigate to Billing and Cost Management → Data exports → Create.

Export details

• Select type: Standard data export
• Export name: spotter-cur-2

Data table content settings

• Select: CUR 2.0
• Additional export content:
• Include resource IDs
• Split cost allocation data
• Time granularity: Daily

Data export delivery options

• Compression type and file format: Parquet - Parquet
• File versioning: Overwrite existing data export file

Data export storage settings

• Use or create an S3 bucket to store exports.
• The S3 bucket policy must allow Spotter to fetch the data.
• After creating the export, edit the bucket policy to include the following blocks:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "AllowLambdaToRead",
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::604877540157:role/aws-cur-ingestion"
      },
      "Action": [
        "s3:ListBucket",
        "s3:GetObject"
      ],
      "Resource": [
        "<s3-bucket-arn>",
        "<s3-bucket-arn>/*"
      ]
    },
    {
      "Sid": "AllowLinkedAccountsToReadAndWrite",
      "Effect": "Allow",
      "Principal": {
        "AWS": ["arn:aws:iam::604877540157:role/Cloud2Admin"]
      },
      "Action": [
        "s3:ListBucket",
        "s3:GetObject",
        "s3:PutObject",
        "s3:DeleteObject"
      ],
      "Resource": [
        "<s3-bucket-arn>",
        "<s3-bucket-arn>/*"
      ]
    }
  ]
}

• S3 path prefix: e.g. spotter

2. Verify Export

• After creation, confirm exports appear in the configured bucket.
• Expected path format:

  s3://<bucket-name>/<prefix>/<export-name>/data/BILLING_PERIOD=YYYY-MM/

• Notes:
• It may take up to 24 hours for data to appear.
• If exports do not appear, ensure AWS permissions to write into the bucket were not removed when adding Spotter read permissions.

3. Deliver S3 URI to Spotter Team

• Once exports are working, send the S3 bucket URI to Team Spotter.
• Example URI:

  s3://<bucket-name>/<prefix>/<export-name>
