Synopsis

  get-public-access-block
--account-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--account-id (string)

The account ID for the AWS account whose PublicAccessBlock configuration you want to retrieve.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples

To list public block access settings for an account

The following get-public-access-block example displays the block public access settings for the specified account.

aws s3control get-public-access-block \
    --account-id 123456789012

Output:

{
   "PublicAccessBlockConfiguration": {
      "BlockPublicPolicy": true,
      "RestrictPublicBuckets": true,
      "IgnorePublicAcls": true,
      "BlockPublicAcls": true
   }
}

Output

PublicAccessBlockConfiguration -> (structure)

The PublicAccessBlock configuration currently in effect for this AWS account.

BlockPublicAcls -> (boolean)

Specifies whether Amazon S3 should block public access control lists (ACLs) for buckets in this account. 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.

This is not supported for Amazon S3 on Outposts.

IgnorePublicAcls -> (boolean)

Specifies whether Amazon S3 should ignore public ACLs for buckets in this account. Setting this element to TRUE causes Amazon S3 to ignore all public ACLs on buckets in this account and any objects that they contain.

Enabling this setting doesn’t affect the persistence of any existing ACLs and doesn’t prevent new public ACLs from being set.

This is not supported for Amazon S3 on Outposts.

BlockPublicPolicy -> (boolean)

Specifies whether Amazon S3 should block public bucket policies for buckets in this account. 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.

This is not supported for Amazon S3 on Outposts.

RestrictPublicBuckets -> (boolean)

Specifies whether Amazon S3 should restrict public bucket policies for buckets in this account. Setting this element to TRUE restricts access to buckets with public policies to only AWS service principals and authorized users within this account.

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.

This is not supported for Amazon S3 on Outposts.
