S3.Client.get_bucket_lifecycle(**kwargs)#

Warning

For an updated version of this API, see GetBucketLifecycleConfiguration. If you configured a bucket lifecycle using the filter element, you should see the updated version of this topic. This topic is provided for backward compatibility.

Note

This operation is not supported by directory buckets.

Returns the lifecycle configuration information set on the bucket. For information about lifecycle configuration, see Object Lifecycle Management.

To use this operation, you must have permission to perform the s3:GetLifecycleConfiguration action. The bucket owner has this permission by default. The bucket owner can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources.

GetBucketLifecycle has the following special error:

  • Error code: NoSuchLifecycleConfiguration

    • Description: The lifecycle configuration does not exist.

    • HTTP Status Code: 404 Not Found

Danger

This operation is deprecated and may not function as expected. This operation should not be used going forward and is only kept for the purpose of backwards compatiblity.

Response Structure

  • (dict) –

    • Rules (list) –

      Container for a lifecycle rule.

      • (dict) –

        Specifies lifecycle rules for an Amazon S3 bucket. For more information, see Put Bucket Lifecycle Configuration in the Amazon S3 API Reference. For examples, see Put Bucket Lifecycle Configuration Examples.

        • Expiration (dict) –

          Specifies the expiration for the lifecycle of the object.

          • Date (datetime) –

            Indicates at what date the object is to be moved or deleted. The date value must conform to the ISO 8601 format. The time is always midnight UTC.

          • Days (integer) –

            Indicates the lifetime, in days, of the objects that are subject to the rule. The value must be a non-zero positive integer.

          • ExpiredObjectDeleteMarker (boolean) –

            Indicates whether Amazon S3 will remove a delete marker with no noncurrent versions. If set to true, the delete marker will be expired; if set to false the policy takes no action. This cannot be specified with Days or Date in a Lifecycle Expiration Policy.

        • ID (string) –

          Unique identifier for the rule. The value can’t be longer than 255 characters.

        • Prefix (string) –

          Object key prefix that identifies one or more objects to which this rule applies.

          Warning

          Replacement must be made for object keys containing special characters (such as carriage returns) when using XML requests. For more information, see XML related object key constraints.

        • Status (string) –

          If Enabled, the rule is currently being applied. If Disabled, the rule is not currently being applied.

        • Transition (dict) –

          Specifies when an object transitions to a specified storage class. For more information about Amazon S3 lifecycle configuration rules, see Transitioning Objects Using Amazon S3 Lifecycle in the Amazon S3 User Guide.

          • Date (datetime) –

            Indicates when objects are transitioned to the specified storage class. The date value must be in ISO 8601 format. The time is always midnight UTC.

          • Days (integer) –

            Indicates the number of days after creation when objects are transitioned to the specified storage class. The value must be a positive integer.

          • StorageClass (string) –

            The storage class to which you want the object to transition.

        • NoncurrentVersionTransition (dict) –

          Container for the transition rule that describes when noncurrent objects transition to the STANDARD_IA, ONEZONE_IA, INTELLIGENT_TIERING, GLACIER_IR, GLACIER, or DEEP_ARCHIVE storage class. If your bucket is versioning-enabled (or versioning is suspended), you can set this action to request that Amazon S3 transition noncurrent object versions to the STANDARD_IA, ONEZONE_IA, INTELLIGENT_TIERING, GLACIER_IR, GLACIER, or DEEP_ARCHIVE storage class at a specific period in the object’s lifetime.

          • NoncurrentDays (integer) –

            Specifies the number of days an object is noncurrent before Amazon S3 can perform the associated action. For information about the noncurrent days calculations, see How Amazon S3 Calculates How Long an Object Has Been Noncurrent in the Amazon S3 User Guide.

          • StorageClass (string) –

            The class of storage used to store the object.

          • NewerNoncurrentVersions (integer) –

            Specifies how many newer noncurrent versions must exist before Amazon S3 can perform the associated action on a given version. If there are this many more recent noncurrent versions, Amazon S3 will take the associated action. For more information about noncurrent versions, see Lifecycle configuration elements in the Amazon S3 User Guide.

        • NoncurrentVersionExpiration (dict) –

          Specifies when noncurrent object versions expire. Upon expiration, Amazon S3 permanently deletes the noncurrent object versions. You set this lifecycle configuration action on a bucket that has versioning enabled (or suspended) to request that Amazon S3 delete noncurrent object versions at a specific period in the object’s lifetime.

          • NoncurrentDays (integer) –

            Specifies the number of days an object is noncurrent before Amazon S3 can perform the associated action. The value must be a non-zero positive integer. For information about the noncurrent days calculations, see How Amazon S3 Calculates When an Object Became Noncurrent in the Amazon S3 User Guide.

          • NewerNoncurrentVersions (integer) –

            Specifies how many newer noncurrent versions must exist before Amazon S3 can perform the associated action on a given version. If there are this many more recent noncurrent versions, Amazon S3 will take the associated action. For more information about noncurrent versions, see Lifecycle configuration elements in the Amazon S3 User Guide.

        • AbortIncompleteMultipartUpload (dict) –

          Specifies the days since the initiation of an incomplete multipart upload that Amazon S3 will wait before permanently removing all parts of the upload. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Configuration in the Amazon S3 User Guide.

          • DaysAfterInitiation (integer) –

            Specifies the number of days after which Amazon S3 aborts an incomplete multipart upload.

The following example gets ACL on the specified bucket.

response = client.get_bucket_lifecycle(
    Bucket='acl1',
