put_public_access_block#
- S3.Client.put_public_access_block(**kwargs)#
Note
This operation is not supported by directory buckets.
Creates or modifies the
PublicAccessBlock
configuration for an Amazon S3 bucket. To use this operation, you must have thes3:PutBucketPublicAccessBlock
permission. For more information about Amazon S3 permissions, see Specifying Permissions in a Policy.Warning
When Amazon S3 evaluates the
PublicAccessBlock
configuration for a bucket or an object, it checks thePublicAccessBlock
configuration for both the bucket (or the bucket that contains the object) and the bucket owner’s account. If thePublicAccessBlock
configurations are different between the bucket and the account, Amazon S3 uses the most restrictive combination of the bucket-level and account-level settings.For more information about when Amazon S3 considers a bucket or an object public, see The Meaning of “Public”.

Request Syntax
response = client.put_public_access_block( Bucket='string', ContentMD5='string', ChecksumAlgorithm='CRC32'|'CRC32C'|'SHA1'|'SHA256', PublicAccessBlockConfiguration={ 'BlockPublicAcls': True|False, 'IgnorePublicAcls': True|False, 'BlockPublicPolicy': True|False, 'RestrictPublicBuckets': True|False }, ExpectedBucketOwner='string' )
- Parameters:
Bucket (string) –
[REQUIRED]
The name of the Amazon S3 bucket whose
PublicAccessBlock
configuration you want to set.ContentMD5 (string) –
The MD5 hash of the
PutPublicAccessBlock
request body.For requests made using the Amazon Web Services Command Line Interface (CLI) or Amazon Web Services SDKs, this field is calculated automatically.
ChecksumAlgorithm (string) –
Indicates the algorithm used to create the checksum for the object when you use the SDK. This header will not provide any additional functionality if you don’t use the SDK. When you send this header, there must be a corresponding
x-amz-checksum
orx-amz-trailer
header sent. Otherwise, Amazon S3 fails the request with the HTTP status code400 Bad Request
. For more information, see Checking object integrity in the Amazon S3 User Guide.If you provide an individual checksum, Amazon S3 ignores any provided
ChecksumAlgorithm
parameter.PublicAccessBlockConfiguration (dict) –
[REQUIRED]
The
PublicAccessBlock
configuration that you want to apply to this Amazon S3 bucket. You can enable the configuration options in any combination. For more information about when Amazon S3 considers a bucket or object public, see The Meaning of “Public” in the Amazon S3 User Guide.BlockPublicAcls (boolean) –
Specifies whether Amazon S3 should block public access control lists (ACLs) for this bucket and objects in this bucket. Setting this element to
TRUE
causes the following behavior:PUT Bucket ACL and PUT Object ACL calls fail if the specified ACL is public.
PUT Object calls fail if the request includes a public ACL.
PUT Bucket calls fail if the request includes a public ACL.
Enabling this setting doesn’t affect existing policies or ACLs.
IgnorePublicAcls (boolean) –
Specifies whether Amazon S3 should ignore public ACLs for this bucket and objects in this bucket. Setting this element to
TRUE
causes Amazon S3 to ignore all public ACLs on this bucket and objects in this bucket.Enabling this setting doesn’t affect the persistence of any existing ACLs and doesn’t prevent new public ACLs from being set.
BlockPublicPolicy (boolean) –
Specifies whether Amazon S3 should block public bucket policies for this bucket. Setting this element to
TRUE
causes Amazon S3 to reject calls to PUT Bucket policy if the specified bucket policy allows public access.Enabling this setting doesn’t affect existing bucket policies.
RestrictPublicBuckets (boolean) –
Specifies whether Amazon S3 should restrict public bucket policies for this bucket. Setting this element to
TRUE
restricts access to this bucket to only Amazon Web Servicesservice principals and authorized users within this account if the bucket has a public policy.Enabling this setting doesn’t affect previously stored bucket policies, except that public and cross-account access within any public bucket policy, including non-public delegation to specific accounts, is blocked.
ExpectedBucketOwner (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).
