API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

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 still using previous version of the lifecycle configuration, it works. For the earlier API description, 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.

GetBucketLifecycleConfiguration has the following special error:

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);
