PutLifecycleConfigurationRequest Class

Container for the parameters to the PutLifecycleConfiguration operation.

This operation is not supported by directory buckets.

Creates a new lifecycle configuration for the bucket or replaces an existing lifecycle configuration. Keep in mind that this will overwrite an existing lifecycle configuration, so if you want to retain any configuration details, they must be included in the new lifecycle configuration. For information about lifecycle configuration, see Managing your storage lifecycle.

Bucket lifecycle configuration now supports specifying a lifecycle rule using an object key name prefix, one or more object tags, object size, or any combination of these. Accordingly, this section describes the latest API. The previous version of the API supported filtering based only on an object key name prefix, which is supported for backward compatibility. For the related API description, see PutBucketLifecycle.

Rules

You specify the lifecycle configuration in your request body. The lifecycle configuration is specified as XML consisting of one or more rules. An Amazon S3 Lifecycle configuration can have up to 1,000 rules. This limit is not adjustable. Each rule consists of the following:

A filter identifying a subset of objects to which the rule applies. The filter can be based on a key name prefix, object tags, object size, or any combination of these.
A status indicating whether the rule is in effect.
One or more lifecycle transition and expiration actions that you want Amazon S3 to perform on the objects identified by the filter. If the state of your bucket is versioning-enabled or versioning-suspended, you can have many versions of the same object (one current version and zero or more noncurrent versions). Amazon S3 provides predefined actions that you can specify for current and noncurrent object versions.

For more information, see Object Lifecycle Management and Lifecycle Configuration Elements.

Permissions

By default, all Amazon S3 resources are private, including buckets, objects, and related subresources (for example, lifecycle configuration and website configuration). Only the resource owner (that is, the Amazon Web Services account that created it) can access the resource. The resource owner can optionally grant access permissions to others by writing an access policy. For this operation, a user must get the s3:PutLifecycleConfiguration permission.

You can also explicitly deny permissions. An explicit deny also supersedes any other permissions. If you want to block users or accounts from removing or deleting objects from your bucket, you must deny them permissions for the following actions:

s3:DeleteObject
s3:DeleteObjectVersion
s3:PutLifecycleConfiguration

For more information about permissions, see Managing Access Permissions to Your Amazon S3 Resources.

The PutLifecycleConfigurationRequest type exposes the following members

Constructors

	Name	Description
	PutLifecycleConfigurationRequest()

Properties

Name	Type	Description
BucketName	System.String	Gets and sets the property BucketName. The name of the bucket for which to set the configuration.
ChecksumAlgorithm	Amazon.S3.ChecksumAlgorithm	Gets and sets the property ChecksumAlgorithm.
Configuration	Amazon.S3.Model.LifecycleConfiguration	The lifecycle configuration to be applied.
ExpectedBucketOwner	System.String	Gets and sets the property ExpectedBucketOwner. 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).
TransitionDefaultMinimumObjectSize	Amazon.S3.TransitionDefaultMinimumObjectSize	Gets and sets the property TransitionDefaultMinimumObjectSize. Indicates which default minimum object size behavior is applied to the lifecycle configuration. `all_storage_classes_128K` - Objects smaller than 128 KB will not transition to any storage class by default. `varies_by_storage_class` - Objects smaller than 128 KB will transition to Glacier Flexible Retrieval or Glacier Deep Archive storage classes. By default, all other storage classes will prevent transitions smaller than 128 KB. To customize the minimum object size for any transition you can add a filter that specifies a custom `ObjectSizeGreaterThan` or `ObjectSizeLessThan` in the body of your transition rule. Custom filters always take precedence over the default transition behavior.

Examples

This example shows how to Get, Put and Delete bucket Lifecycle Configurations.
A Lifecycle Configuration allows an owner to configure when specific objects should be deleted. Objects to be deleted are specified with a prefix.
The configuration being used has rules that delete objects with a specific prefix and objects in a specific subdirectory.

LifecycleConfiguration samples


// Create a client
AmazonS3Client client = new AmazonS3Client();


// Put sample lifecycle configuration (overwrite an existing configuration)
LifecycleConfiguration newConfiguration = new LifecycleConfiguration
{
    Rules = new List<LifecycleRule>
    {
        // Rule to delete keys with prefix "Test-" after 5 days
        new LifecycleRule
        {
            Prefix = "Test-",
            Expiration = new LifecycleRuleExpiration { Days = 5 }
        },
        // Rule to delete keys in subdirectory "Logs" after 2 days
        new LifecycleRule
        {
            Prefix = "Logs/",
            Expiration = new LifecycleRuleExpiration  { Days = 2 },
            Id = "log-file-removal"
        }
    }
};
PutLifecycleConfigurationRequest putRequest = new PutLifecycleConfigurationRequest
{
    BucketName = "SampleBucket",
    Configuration = newConfiguration
};
client.PutLifecycleConfiguration(putRequest);


// Retrieve current configuration
GetLifecycleConfigurationRequest getRequest = new GetLifecycleConfigurationRequest
{
    BucketName = "SampleBucket"
};
LifecycleConfiguration configuration = client.GetLifecycleConfiguration(getRequest).Configuration;

Console.WriteLine("Configuration contains {0} rules", configuration.Rules.Count);
foreach (LifecycleRule rule in configuration.Rules)
{
    Console.WriteLine("Rule");
    Console.WriteLine(" Prefix = " + rule.Prefix);
    Console.WriteLine(" Expiration (days) = " + rule.Expiration.Days);
    Console.WriteLine(" Id = " + rule.Id);
    Console.WriteLine(" Status = " + rule.Status);
}


// Put a new configuration and overwrite the existing configuration
configuration.Rules.RemoveAt(0);    // remove first rule
client.PutLifecycleConfiguration(putRequest);

// Delete current configuration
DeleteLifecycleConfigurationRequest deleteRequest = new DeleteLifecycleConfigurationRequest
{
    BucketName = "SampleBucket"
};
client.DeleteLifecycleConfiguration(deleteRequest);


// Retrieve current configuration and verify that it is null
configuration = client.GetLifecycleConfiguration(getRequest).Configuration;
Debug.Assert(configuration == null);
