2024/12/02 - Amazon Simple Storage Service - 2 updated api methods
Changes Amazon S3 introduces support for AWS Dedicated Local Zones
{'CreateBucketConfiguration': {'Bucket': {'DataRedundancy': {'SingleLocalZone'}}, 'Location': {'Type': {'LocalZone'}}}}
Creates a new S3 bucket. To create a bucket, you must set up Amazon S3 and have a valid Amazon Web Services Access Key ID to authenticate requests. Anonymous requests are never allowed to create buckets. By creating the bucket, you become the bucket owner.
There are two types of buckets: general purpose buckets and directory buckets. For more information about these bucket types, see Creating, configuring, and working with Amazon S3 buckets in the Amazon S3 User Guide.
General purpose bucket permissions - In addition to the s3:CreateBucket permission, the following permissions are required in a policy when your CreateBucket request includes specific headers:
Access control lists (ACLs) - In your CreateBucket request, if you specify an access control list (ACL) and set it to public-read, public-read-write, authenticated-read, or if you explicitly specify any other custom ACLs, both s3:CreateBucket and s3:PutBucketAcl permissions are required. In your CreateBucket request, if you set the ACL to private, or if you don't specify any ACLs, only the s3:CreateBucket permission is required.
Object Lock - In your CreateBucket request, if you set x-amz-bucket-object-lock-enabled to true, the s3:PutBucketObjectLockConfiguration and s3:PutBucketVersioning permissions are required.
S3 Object Ownership - If your CreateBucket request includes the x-amz-object-ownership header, then the s3:PutBucketOwnershipControls permission is required.
S3 Block Public Access - If your specific use case requires granting public access to your S3 resources, you can disable Block Public Access. Specifically, you can create a new bucket with Block Public Access enabled, then separately call the DeletePublicAccessBlock API. To use this operation, you must have the s3:PutBucketPublicAccessBlock permission. For more information about S3 Block Public Access, see Blocking public access to your Amazon S3 storage in the Amazon S3 User Guide.
Directory bucket permissions - You must have the s3express:CreateBucket permission in an IAM identity-based policy instead of a bucket policy. Cross-account access to this API operation isn't supported. This operation can only be performed by the Amazon Web Services account that owns the resource. For more information about directory bucket policies and permissions, see Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone in the Amazon S3 User Guide.
Directory buckets - The HTTP Host header syntax is s3express-control.region-code.amazonaws.com.
The following operations are related to CreateBucket:

string
The canned ACL to apply to the bucket.
string
[REQUIRED]
The name of the bucket to create.
General purpose buckets - For information about bucket naming restrictions, see Bucket naming rules in the Amazon S3 User Guide.
Directory buckets - When you use this operation with a directory bucket, you must use path-style requests in the format https://s3express-control.region-code.amazonaws.com/bucket-name ``. Virtual-hosted-style requests aren't supported. Directory bucket names must be unique in the chosen Zone (Availability Zone or Local Zone). Bucket names must also follow the format ``bucket-base-name--zone-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide
dict
The configuration information for the bucket.
LocationConstraint (string) --
Specifies the Region where the bucket will be created. You might choose a Region to optimize latency, minimize costs, or address regulatory requirements. For example, if you reside in Europe, you will probably find it advantageous to create buckets in the Europe (Ireland) Region. For more information, see Accessing a bucket in the Amazon S3 User Guide.
If you don't specify a Region, the bucket is created in the US East (N. Virginia) Region (us-east-1) by default.
Location (dict) --
Specifies the location where the bucket will be created.
Directory buckets - The location type is Availability Zone or Local Zone. When the location type is Local Zone, your Local Zone must be in opt-in status. Otherwise, you get an HTTP 400 Bad Request error with the error code Access denied. To learn more about opt-in Local Zones, see `Opt-in Dedicated Local Zones <https://docs.aws.amazon.com/AmazonS3/latest/userguide/opt-in-directory-bucket-lz.html>`__in the Amazon S3 User Guide.
Type (string) --
The type of location where the bucket will be created.
Name (string) --
The name of the location where the bucket will be created.
For directory buckets, the name of the location is the Zone ID of the Availability Zone (AZ) or Local Zone (LZ) where the bucket will be created. An example AZ ID value is usw2-az1.
Bucket (dict) --
Specifies the information about the bucket that will be created.
DataRedundancy (string) --
The number of Zone (Availability Zone or Local Zone) that's used for redundancy for the bucket.
Type (string) --
The type of bucket.
string
Allows grantee the read, write, read ACP, and write ACP permissions on the bucket.
string
Allows grantee to list the objects in the bucket.
string
Allows grantee to read the bucket ACL.
string
Allows grantee to create new objects in the bucket.
For the bucket and object owners of existing objects, also allows deletions and overwrites of those objects.
string
Allows grantee to write the ACL for the applicable bucket.
boolean
Specifies whether you want S3 Object Lock to be enabled for the new bucket.
string
The container element for object ownership for a bucket's ownership controls.
BucketOwnerPreferred - Objects uploaded to the bucket change ownership to the bucket owner if the objects are uploaded with the bucket-owner-full-control canned ACL.
ObjectWriter - The uploading account will own the object if the object is uploaded with the bucket-owner-full-control canned ACL.
BucketOwnerEnforced - Access control lists (ACLs) are disabled and no longer affect permissions. The bucket owner automatically owns and has full control over every object in the bucket. The bucket only accepts PUT requests that don't specify an ACL or specify bucket owner full control ACLs (such as the predefined bucket-owner-full-control canned ACL or a custom ACL in XML format that grants the same permissions).
By default, ObjectOwnership is set to BucketOwnerEnforced and ACLs are disabled. We recommend keeping ACLs disabled, except in uncommon use cases where you must control access for each object individually. For more information about S3 Object Ownership, see Controlling ownership of objects and disabling ACLs for your bucket in the Amazon S3 User Guide.

(dict) --
Location (string) --
A forward slash followed by the name of the bucket.
{'BucketLocationType': {'LocalZone'}}
You can use this operation to determine if a bucket exists and if you have permission to access it. The action returns a 200 OK if the bucket exists and you have permission to access it.
General purpose buckets - Request to public buckets that grant the s3:ListBucket permission publicly do not need to be signed. All other HeadBucket requests must be authenticated and signed by using IAM credentials (access key ID and secret access key for the IAM identities). All headers with the x-amz- prefix, including x-amz-copy-source, must be signed. For more information, see REST Authentication.
Directory buckets - You must use IAM credentials to authenticate and authorize your access to the HeadBucket API operation, instead of using the temporary security credentials through the CreateSession API operation.
Amazon Web Services CLI or SDKs handles authentication and authorization on your behalf.
Permissions
General purpose bucket permissions - To use this operation, you must have permissions to perform the s3:ListBucket action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Managing access permissions to your Amazon S3 resources in the Amazon S3 User Guide.
Directory bucket permissions - You must have the s3express:CreateSession permission in the Action element of a policy. By default, the session is in the ReadWrite mode. If you want to restrict the access, you can explicitly set the s3express:SessionMode condition key to ReadOnly on the bucket. For more information about example bucket 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.
HTTP Host header syntax
Directory buckets - The HTTP Host header syntax is Bucket-name.s3express-zone-id.region-code.amazonaws.com.
See also: AWS API Documentation
Request Syntax
client.head_bucket( Bucket='string', ExpectedBucketOwner='string' )
string
[REQUIRED]
The bucket name.
Directory buckets - When you use this operation with a directory bucket, you must use virtual-hosted-style requests in the format Bucket-name.s3express-zone-id.region-code.amazonaws.com. Path-style requests are not supported. Directory bucket names must be unique in the chosen Zone (Availability Zone or Local Zone). Bucket names must follow the format bucket-base-name--zone-id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.
Access points - When you use this action with an access point, you must provide the alias of the access point in place of the bucket name or specify the access point ARN. When using the access point ARN, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName-AccountId.s3-accesspoint.*Region*.amazonaws.com. When using this action with an access point through the Amazon Web Services SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using access points in the Amazon S3 User Guide.
Object Lambda access points - When you use this API operation with an Object Lambda access point, provide the alias of the Object Lambda access point in place of the bucket name. If the Object Lambda access point alias in a request is not valid, the error code InvalidAccessPointAliasError is returned. For more information about InvalidAccessPointAliasError, see List of Error Codes.
S3 on Outposts - When you use this action with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName-AccountId.outpostID.s3-outposts.Region.amazonaws.com. When you use this action with S3 on Outposts through the Amazon Web Services SDKs, you provide the Outposts access point ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see What is S3 on Outposts? in the Amazon S3 User Guide.
string
The account ID of the expected bucket owner. If the account ID that you provide does not match the actual owner of the bucket, the request fails with the HTTP status code 403 Forbidden (access denied).
