expiration object s3 through php sdk

Question

I want to set an expiration date for an object on s3 I create the object like this:

$this->s3->putObject(array(
'Bucket' => BUCKET,
'Key'=> "path",
'SourceFile'   => $fileTmp,
'Expires' => time()+2*60,
'ACL'    => 'private'
));

But when I check file on aws S3 Console the object keeps:

Expiry Date:    None
Expiration Rule:    N/A

How can I set object expiration?

Answer 1

Use the putBucketLifecycle method like that:

    $result = $client->putBucketLifecycleConfiguration([
        'Bucket' => '<string>', // REQUIRED
        'LifecycleConfiguration' => [
            'Rules' => [ // REQUIRED
                [
                    'Expiration' => [
                        'Date' => <integer || string || DateTime>,
                        'Days' => <integer>,
                        'ExpiredObjectDeleteMarker' => true || false,
                    ],
                    'ID' => '<string>',
                    'Prefix' => '<string>',
                    'Status' => 'Enabled|Disabled', // REQUIRED
                ],
                // ...
            ],
],
]);

Note

1. This method will replace all the existing rules. So if you need to append a new rule I recommend you to use getBucketLifecycleConfiguration before and merge the previous rules with the new one.
2. You can only set a Lifecycle rule on a prefix (or tag), not an object.
3. 'prefix' is your path, excluding the file name, with a trailing slash.

Answer 2

Lifecycle policies are set per bucket, not per file.

Here's how to set a Lifecycle policy for a bucket:

1. In AWS S3 console (the web version), click on the bucket
2. Choose Properties ; expand Lifecycle
3. Add Rule appears. Click it.
4. Complete the wizard using your own set of rules
