## 2. Enable bucket lifecycle configuration

- Create a bucket lifecycle configuration which expires the objects under the prefix `old/` on `2020-01-01T00:00:00.000Z` date and the objects under `temp/` after 7 days.
- Enable bucket lifecycle configuration using `mc`:

```sh
$ mc ilm import play/testbucket <<EOF
{
    "Rules": [
        {

	return r.calculateBucketReplicationStats(bucket, bucketStats)

	if !ok {
		v = newInQueueStats(r.registry, bucket)
	}
	atomic.AddInt64(&v.nowBytes, sz)
	atomic.AddInt64(&v.nowCount, 1)

You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server. You can also connect using any S3-compatible tool, such as the MinIO Client `mc` commandline tool. See [Test using MinIO Client `mc`](#test-using-minio-client-mc) for more information on...
