CSP Billing Adapter Amazon Plugin

This is a plugin for csp-billing-adapter that provides CSP hook implementations. This includes the hooks defined in the csp_hookspecs.py module. To enable metered billing in Amazon the container or instance is required to have MeterUsage permissions. This can be added with a role policy such as:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "CSPBillingAdapterPermissions",
            "Effect": "Allow",
            "Action": [
                "aws-marketplace:MeterUsage"
            ],
            "Resource": "*"
        }
    ]
}

Meter billing

The meter_billing function accepts a dictionary mapping of dimension name to usage quantity. This information is used to bill the customer for the product ID that is configured in the adapter. If there is an exception with metered billing the exception is raised.

Get CSP Name

The get_csp_name function returns the name of the CSP provider. In this case it is Amazon.

Get Account Info

The get_account_info function provides metadata information for the running instance or container. The structure of this information is as follows:

{
    "document": {
        "accountId": "1234567890",
        "architecture": "x86_64",
        "availabilityZone": "us-east-1d",
        "billingProducts": null,
        "devpayProductCodes": null,
        "marketplaceProductCodes": null,
        "imageId": "ami-1234567890abcdefg",
        "instanceId": "i-1234567890abcdefg",
        "instanceType": "t2.micro",
        "kernelId": null,
        "pendingTime": "2023-05-23T19:46:52Z",
        "privateIp": "192.168.0.201",
        "ramdiskId": null,
        "region": "us-east-1",
        "version": "2017-09-30"
    },
    "signature": "signature",
    "pkcs7": "pkcs7",
    "cloud_provider": "amazon"
}

This information is pulled from the Amazon Instance metadata endpoint: http://169.254.169.254/latest. Note: the exact information in the document entry may vary.
