put-bucket-logging

Description

Set the logging parameters for a bucket and to specify permissions for who can view and modify the logging parameters. All logs are saved to buckets in the same Amazon Web Services Region as the source bucket. To set the logging status of a bucket, you must be the bucket owner.

The bucket owner is automatically granted FULL_CONTROL to all logs. You use the Grantee request element to grant access to other people. The Permissions request element specifies the kind of access the grantee has to the logs.

Warning

If the target bucket for log delivery uses the bucket owner enforced setting for S3 Object Ownership, you can’t use the Grantee request element to grant access to others. Permissions can only be granted using policies. For more information, see Permissions for server access log delivery in the Amazon S3 User Guide .

Grantee Values

You can specify the person (grantee) to whom you’re assigning access rights (using request elements) in the following ways:

  • By the person’s ID: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CanonicalUser"><ID><>ID<></ID><DisplayName><>GranteesEmail<></DisplayName> </Grantee> DisplayName is optional and ignored in the request.

  • By Email address: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="AmazonCustomerByEmail"><EmailAddress><>Grantees@email.com<></EmailAddress></Grantee> The grantee is resolved to the CanonicalUser and, in a response to a GET Object acl request, appears as the CanonicalUser.

  • By URI: <Grantee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Group"><URI><>http://acs.amazonaws.com/groups/global/AuthenticatedUsers<></URI></Grantee>

To enable logging, you use LoggingEnabled and its children request elements. To disable logging, you use an empty BucketLoggingStatus request element:

<BucketLoggingStatus xmlns="http://doc.s3.amazonaws.com/2006-03-01" />

Synopsis

  put-bucket-logging
--bucket <value>
--bucket-logging-status <value>
[--content-md5 <value>]
[--checksum-algorithm <value>]
[--expected-bucket-owner <value>]

Options

--bucket (string)

The name of the bucket for which to set the logging parameters.

--bucket-logging-status (structure)

Container for logging status information.

LoggingEnabled -> (structure)

Describes where logs are stored and the prefix that Amazon S3 assigns to all log object keys for a bucket. For more information, see PUT Bucket logging in the Amazon S3 API Reference .

TargetBucket -> (string)

Specifies the bucket where you want Amazon S3 to store server access logs. You can have your logs delivered to any bucket that you own, including the same bucket that is being logged. You can also configure multiple buckets to deliver their logs to the same target bucket. In this case, you should choose a different TargetPrefix for each source bucket so that the delivered log files can be distinguished by key.

TargetGrants -> (list)

Container for granting information.

Buckets that use the bucket owner enforced setting for Object Ownership don’t support target grants. For more information, see Permissions for server access log delivery in the Amazon S3 User Guide .

(structure)

Container for granting information.

Buckets that use the bucket owner enforced setting for Object Ownership don’t support target grants. For more information, see Permissions server access log delivery in the Amazon S3 User Guide .

Grantee -> (structure)

Container for the person being granted permissions.

DisplayName -> (string)

Screen name of the grantee.

EmailAddress -> (string)

Email address of the grantee.

Note

Using email addresses to specify a grantee is only supported in the following Amazon Web Services Regions:

  • US East (N. Virginia)

  • US West (N. California)

  • US West (Oregon)

  • Asia Pacific (Singapore)

  • Asia Pacific (Sydney)

  • Asia Pacific (Tokyo)

  • Europe (Ireland)

  • South America (São Paulo)

For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the Amazon Web Services General Reference.

ID -> (string)

The canonical user ID of the grantee.

Type -> (string)

Type of grantee

URI -> (string)

URI of the grantee group.

Permission -> (string)

Logging permissions assigned to the grantee for the bucket.

TargetPrefix -> (string)

A prefix for all log object keys. If you store log files from multiple Amazon S3 buckets in a single bucket, you can use a prefix to distinguish which log files came from which bucket.

JSON Syntax:

{
  "LoggingEnabled": {
    "TargetBucket": "string",
    "TargetGrants": [
      {
        "Grantee": {
          "DisplayName": "string",
          "EmailAddress": "string",
          "ID": "string",
          "Type": "CanonicalUser"|"AmazonCustomerByEmail"|"Group",
          "URI": "string"
        },
        "Permission": "FULL_CONTROL"|"READ"|"WRITE"
      }
      ...
    ],
    "TargetPrefix": "string"
  }
}

--content-md5 (string)

The MD5 hash of the PutBucketLogging request body.

For requests made using the Amazon Web Services Command Line Interface (CLI) or Amazon Web Services SDKs, this field is calculated automatically.

--checksum-algorithm (string)

Indicates the algorithm used to create the checksum for the object when using the SDK. This header will not provide any additional functionality if not using the SDK. When sending this header, there must be a corresponding x-amz-checksum or x-amz-trailer header sent. Otherwise, Amazon S3 fails the request with the HTTP status code 400 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.

Possible values:

  • CRC32

  • CRC32C

  • SHA1

  • SHA256

--expected-bucket-owner (string)

The account ID of the expected bucket owner. If the bucket is owned by a different account, the request fails with the HTTP status code 403 Forbidden (access denied).

--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

Example 1: To set bucket policy logging

The following put-bucket-logging example sets the logging policy for MyBucket. First, grant the logging service principal permission in your bucket policy using the put-bucket-policy command.

aws s3api put-bucket-policy \
    --bucket MyBucket \
    --policy file://policy.json

Contents of policy.json:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "S3ServerAccessLogsPolicy",
            "Effect": "Allow",
            "Principal": {"Service": "logging.s3.amazonaws.com"},
            "Action": "s3:PutObject",
            "Resource": "arn:aws:s3:::MyBucket/Logs/*",
            "Condition": {
                "ArnLike": {"aws:SourceARN": "arn:aws:s3:::SOURCE-BUCKET-NAME"},
                "StringEquals": {"aws:SourceAccount": "SOURCE-AWS-ACCOUNT-ID"}
            }
        }
    ]
}

To apply the logging policy, use put-bucket-logging.

aws s3api put-bucket-logging \
    --bucket MyBucket \
    --bucket-logging-status file://logging.json

Contents of logging.json:

{
     "LoggingEnabled": {
         "TargetBucket": "MyBucket",
         "TargetPrefix": "Logs/"
     }
 }

Note

The put-bucket-policy command is required to grant s3:PutObject permissions to the logging service principal.

For more information, see Amazon S3 Server Access Logging in the Amazon S3 User Guide.

Example 2: To set a bucket policy for logging access to only a single user

The following put-bucket-logging example sets the logging policy for MyBucket. The AWS user bob@example.com will have full control over the log files, and no one else has any access. First, grant S3 permission with put-bucket-acl.

aws s3api put-bucket-acl \
    --bucket MyBucket \
    --grant-write URI=http://acs.amazonaws.com/groups/s3/LogDelivery \
    --grant-read-acp URI=http://acs.amazonaws.com/groups/s3/LogDelivery

Then apply the logging policy using put-bucket-logging.

aws s3api put-bucket-logging \
    --bucket MyBucket \
    --bucket-logging-status file://logging.json

Contents of logging.json:

{
    "LoggingEnabled": {
        "TargetBucket": "MyBucket",
        "TargetPrefix": "MyBucketLogs/",
        "TargetGrants": [
            {
                "Grantee": {
                    "Type": "AmazonCustomerByEmail",
                    "EmailAddress": "bob@example.com"
                },
                "Permission": "FULL_CONTROL"
            }
        ]
    }
}

Note

the put-bucket-acl command is required to grant S3’s log delivery system the necessary permissions (write and read-acp permissions).

For more information, see Amazon S3 Server Access Logging in the Amazon S3 Developer Guide.
