The following environment variables are supported:

  • AWS_ACCESS_KEY_ID - to obtain Access Key ID

You may uncheck this for accounts that are not allowed to list CloudFront distributions to avoid failed tasks and warnings in the log.

External Buckets - you may edit external buckets associated with the account. Each bucket must be specified on a new line. Optional path is also supported, slash is used as delimiter, for example my-bucket/and/optional/path
