IAM policy to use Amazon S3 objects with DataBrew

The AwsGlueDataBrewSpecificS3BucketPolicy policy grants the permissions needed to access S3 on behalf of nonadministrative users.

Customize the policy as follows:

1. Replace the Amazon S3 paths in the policy so they point to the paths that you want to use. In the sample text, BUCKET-NAME-1/SPECIFIC-OBJECT-NAME represents a specific object or file. BUCKET-NAME-2/ represents all objects (*) whose path name starts with BUCKET-NAME-2/. Update these to name the buckets that you are using.

2. (Optional) Use wildcards in the Amazon S3 paths to further restrict permissions. For more information, see IAM policy elements: Variables and tags in the IAM User Guide.

   As part of doing this, you might restrict permissions for the actions s3:PutObject and s3:PutBucketCORS. These actions are required only for users who create DataBrew projects, because those users need to be able to send output files to S3.

For more information and to see some examples of what you can add to an IAM policy for Amazon S3, see Bucket Policy Examples in the Amazon S3 Developer Guide.

The following table describes the permissions granted by this policy.

Action	Resource	Description
"s3:GetObject"	"arn:aws:s3:::bucket_name/*", "arn:aws:s3:::bucket_name"	Allows you to preview your files.
"s3:PutObject" "s3:PutBucketCORS"	"arn:aws:s3:::bucket_name/*", "arn:aws:s3:::bucket_name"	Allows sending output files to S3.
"s3:DeleteObject"	"arn:aws:s3:::bucket_name/*", "arn:aws:s3:::bucket_name"	Allows deleting an object.
