AWS list resources

Uses the AWS Cloud Control API to list resources that are present in a given AWS account and region(s). Discovered resources are written to a JSON output file.

Usage

Make sure you have AWS credentials configured for your target account (e.g., using environment variables) and run, for example:

pip install -r requirements.txt

python aws_list_resources.py --regions us-east-1,eu-central-1

Notes

• The script will only be able to discover resources that are currently supported by the AWS Cloud Control API and offer support for the "List" operation:

  https://docs.aws.amazon.com/cloudcontrolapi/latest/userguide/supported-resources.html

  It is further restricted to those resources where the "List" operation does not expect any additional parameters.

• If the IAM user or role you use to run the script does not have permissions to interact with certain AWS services or regions, their resources will be missed. Note that permissions can be restricted on different levels, such as SCPs, identity-based polices, etc. The JSON output file will contain a list of resource types where listing was denied.

• The JSON output file will also contain default resources that were created by AWS, independent of whether you actually used the service or not.
