Bucket access policies allow you to define precise, S3-compatible access control for one bucket. They are evaluated after organization access policies. See Manage Bucket Policies for examples and further information. This data source provides a type-safe data structure for creating an S3-compatible JSON bucket policy.

​

    effect   = "Allow"
    action   = ["s3:*"]
