Struct CreateSessionFluentBuilder

pub struct CreateSessionFluentBuilder { /* private fields */ }
Expand description

Fluent builder constructing a request to CreateSession.

Creates a session that establishes temporary security credentials to support fast authentication and authorization for the Zonal endpoint API operations on directory buckets. For more information about Zonal endpoint API operations that include the Availability Zone in the request endpoint, see S3 Express One Zone APIs in the Amazon S3 User Guide.

To make Zonal endpoint API requests on a directory bucket, use the CreateSession API operation. Specifically, you grant s3express:CreateSession permission to a bucket in a bucket policy or an IAM identity-based policy. Then, you use IAM credentials to make the CreateSession API request on the bucket, which returns temporary security credentials that include the access key ID, secret access key, session token, and expiration. These credentials have associated permissions to access the Zonal endpoint API operations. After the session is created, you don’t need to use other policies to grant permissions to each Zonal endpoint API individually. Instead, in your Zonal endpoint API requests, you sign your requests by applying the temporary security credentials of the session to the request headers and following the SigV4 protocol for authentication. You also apply the session token to the x-amz-s3session-token request header for authorization. Temporary security credentials are scoped to the bucket and expire after 5 minutes. After the expiration time, any calls that you make with those credentials will fail. You must use IAM credentials again to make a CreateSession API request that generates a new set of temporary credentials for use. Temporary credentials cannot be extended or refreshed beyond the original specified interval.

If you use Amazon Web Services SDKs, SDKs handle the session token refreshes automatically to avoid service interruptions when a session expires. We recommend that you use the Amazon Web Services SDKs to initiate and manage requests to the CreateSession API. For more information, see Performance guidelines and design patterns in the Amazon S3 User Guide.

  • You must make requests for this API operation to the Zonal endpoint. These endpoints support virtual-hosted-style requests in the format https://bucket_name.s3express-az_id.region.amazonaws.com. Path-style requests are not supported. For more information, see Regional and Zonal endpoints in the Amazon S3 User Guide.

  • CopyObject API operation - Unlike other Zonal endpoint API operations, the CopyObject API operation doesn't use the temporary security credentials returned from the CreateSession API operation for authentication and authorization. For information about authentication and authorization of the CopyObject API operation on directory buckets, see CopyObject.

  • HeadBucket API operation - Unlike other Zonal endpoint API operations, the HeadBucket API operation doesn't use the temporary security credentials returned from the CreateSession API operation for authentication and authorization. For information about authentication and authorization of the HeadBucket API operation on directory buckets, see HeadBucket.
Permissions

To obtain temporary security credentials, you must create a bucket policy or an IAM identity-based policy that grants s3express:CreateSession permission to the bucket. In a policy, you can have the s3express:SessionMode condition key to control who can create a ReadWrite or ReadOnly session. For more information about ReadWrite or ReadOnly sessions, see x-amz-create-session-mode . For example policies, see Example bucket policies for S3 Express One Zone and Amazon Web Services Identity and Access Management (IAM) identity-based policies for S3 Express One Zone in the Amazon S3 User Guide.

To grant cross-account access to Zonal endpoint API operations, the bucket policy should also grant both accounts the s3express:CreateSession permission.

If you want to encrypt objects with SSE-KMS, you must also have the kms:GenerateDataKey and the kms:Decrypt permissions in IAM identity-based policies and KMS key policies for the target KMS key.

Encryption

For directory buckets, there are only two supported options for server-side encryption: server-side encryption with Amazon S3 managed keys (SSE-S3) (AES256) and server-side encryption with KMS keys (SSE-KMS) (aws:kms). We recommend that the bucket's default encryption uses the desired encryption configuration and you don't override the bucket default encryption in your CreateSession requests or PUT object requests. Then, new objects are automatically encrypted with the desired encryption settings. For more information, see Protecting data with server-side encryption in the Amazon S3 User Guide. For more information about the encryption overriding behaviors in directory buckets, see Specifying server-side encryption with KMS for new object uploads.

For Zonal endpoint (object-level) API operations except CopyObject and UploadPartCopy, you authenticate and authorize requests through CreateSession for low latency. To encrypt new objects in a directory bucket with SSE-KMS, you must specify SSE-KMS as the directory bucket's default encryption configuration with a KMS key (specifically, a customer managed key). Then, when a session is created for Zonal endpoint API operations, new objects are automatically encrypted and decrypted with SSE-KMS and S3 Bucket Keys during the session.

Only 1 customer managed key is supported per directory bucket for the lifetime of the bucket. The Amazon Web Services managed key (aws/s3) isn't supported. After you specify SSE-KMS as your bucket's default encryption configuration with a customer managed key, you can't change the customer managed key for the bucket's SSE-KMS configuration.

In the Zonal endpoint API calls (except CopyObject and UploadPartCopy) using the REST API, you can't override the values of the encryption settings (x-amz-server-side-encryption, x-amz-server-side-encryption-aws-kms-key-id, x-amz-server-side-encryption-context, and x-amz-server-side-encryption-bucket-key-enabled) from the CreateSession request. You don't need to explicitly specify these encryption settings values in Zonal endpoint API calls, and Amazon S3 will use the encryption settings values from the CreateSession request to protect new objects in the directory bucket.

When you use the CLI or the Amazon Web Services SDKs, for CreateSession, the session token refreshes automatically to avoid service interruptions when a session expires. The CLI or the Amazon Web Services SDKs use the bucket's default encryption configuration for the CreateSession request. It's not supported to override the encryption settings values in the CreateSession request. Also, in the Zonal endpoint API calls (except CopyObject and UploadPartCopy), it's not supported to override the values of the encryption settings from the CreateSession request.
HTTP Host header syntax

Directory buckets - The HTTP Host header syntax is Bucket_name.s3express-az_id.region.amazonaws.com.

pub fn bucket_key_enabled(self, input: bool) -> Self

Specifies whether Amazon S3 should use an S3 Bucket Key for object encryption with server-side encryption using KMS keys (SSE-KMS).

S3 Bucket Keys are always enabled for GET and PUT operations in a directory bucket and can’t be disabled. S3 Bucket Keys aren't supported, when you copy SSE-KMS encrypted objects from general purpose buckets to directory buckets, from directory buckets to general purpose buckets, or between directory buckets, through CopyObject, UploadPartCopy, the Copy operation in Batch Operations, or the import jobs. In this case, Amazon S3 makes a call to KMS every time a copy request is made for a KMS-encrypted object.
