get_bucket_lifecycle_configuration(**kwargs)¶Note
Bucket lifecycle configuration now supports specifying a lifecycle rule using an object key name prefix, one or more object tags, or a combination of both. Accordingly, this section describes the latest API. The response describes the new filter element that you can use to specify a filter to select a subset of objects to which the rule applies. If you are using a previous version of the lifecycle configuration, it still works. For the earlier action, see GetBucketLifecycle.
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.
GetBucketLifecycleConfigurationhas the following special error:

Response Structure
(dict) --
Rules (list) --
Container for a lifecycle rule.
(dict) --
A lifecycle rule for individual objects in an Amazon S3 bucket.
Expiration (dict) --
Specifies the expiration for the lifecycle of the object in the form of date, days and, whether the object has a delete marker.
Date (datetime) --
Indicates at what date the object is to be moved or deleted. Should be in GMT ISO 8601 Format.
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 cannot be longer than 255 characters.
Prefix (string) --
Prefix identifying one or more objects to which the rule applies. This is no longer used; use Filter instead.
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.
Filter (dict) --
The Filter is used to identify objects that a Lifecycle Rule applies to. A Filter must have exactly one of Prefix , Tag , or And specified. Filter is required if the LifecycleRule does not contain a Prefix element.
Prefix (string) --
Prefix identifying one or more objects to which the 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.
Tag (dict) --
This tag must exist in the object's tag set in order for the rule to apply.
Key (string) --
Name of the object key.
Value (string) --
Value of the tag.
ObjectSizeGreaterThan (integer) --
Minimum object size to which the rule applies.
ObjectSizeLessThan (integer) --
Maximum object size to which the rule applies.
And (dict) --
This is used in a Lifecycle Rule Filter to apply a logical AND to two or more predicates. The Lifecycle Rule will apply to any object matching all of the predicates configured inside the And operator.
Prefix (string) --
Prefix identifying one or more objects to which the rule applies.
Tags (list) --
All of these tags must exist in the object's tag set in order for the rule to apply.
(dict) --
A container of a key value name pair.
Key (string) --
Name of the object key.
Value (string) --
Value of the tag.
ObjectSizeGreaterThan (integer) --
Minimum object size to which the rule applies.
ObjectSizeLessThan (integer) --
Maximum object size to which the rule applies.
Status (string) --
If 'Enabled', the rule is currently being applied. If 'Disabled', the rule is not currently being applied.
Transitions (list) --
Specifies when an Amazon S3 object transitions to a specified storage class.
(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.
NoncurrentVersionTransitions (list) --
Specifies the transition rule for the lifecycle rule that describes when noncurrent objects transition to a specific 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 a specific storage class at a set period in the object's lifetime.
(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 noncurrent versions Amazon S3 will retain. 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 noncurrent versions Amazon S3 will retain. 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 Policy in the Amazon S3 User Guide .
DaysAfterInitiation (integer) --
Specifies the number of days after which Amazon S3 aborts an incomplete multipart upload.
