Bucket Lifecycle Configuration Quickstart Guide

Enable object lifecycle configuration on buckets to setup automatic deletion of objects after a specified number of days or a specified date.

1. Prerequisites

Install MinIO - MinIO Quickstart Guide.
Install mc - mc Quickstart Guide

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:

$ mc ilm import play/testbucket <<EOF
{
    "Rules": [
        {
            "Expiration": {
                "Date": "2020-01-01T00:00:00.000Z"
            },
            "ID": "OldPictures",
            "Filter": {
                "Prefix": "old/"
            },
            "Status": "Enabled"
        },
        {
            "Expiration": {
                "Days": 7
            },
            "ID": "TempUploads",
            "Filter": {
                "Prefix": "temp/"
            },
            "Status": "Enabled"
        }
    ]
}
EOF

Lifecycle configuration imported successfully to `play/testbucket`.

List the current settings

$ mc ilm ls play/testbucket
     ID     |  Prefix  |  Enabled   | Expiry |  Date/Days   |  Transition  |    Date/Days     |  Storage-Class   |       Tags
------------|----------|------------|--------|--------------|--------------|------------------|------------------|------------------
OldPictures |   old/   |    ✓       |  ✓     |  1 Jan 2020  |     ✗        |                  |                  |
------------|----------|------------|--------|--------------|--------------|------------------|------------------|------------------
TempUploads |  temp/   |    ✓       |  ✓     |   7 day(s)   |     ✗        |                  |                  |
------------|----------|------------|--------|--------------|--------------|------------------|------------------|------------------

3. Activate ILM versioning features

This will only work with a versioned bucket, take a look at Bucket Versioning Guide for more understanding.

3.1 Automatic removal of non current objects versions

A non-current object version is a version which is not the latest for a given object. It is possible to set up an automatic removal of non-current versions when a version becomes older than a given number of days.

e.g., To scan objects stored under user-uploads/ prefix and remove versions older than one year.

{
    "Rules": [
        {
            "ID": "Removing all old versions",
            "Filter": {
                "Prefix": "users-uploads/"
            },
            "NoncurrentVersionExpiration": {
                "NoncurrentDays": 365
            },
            "Status": "Enabled"
        }
    ]
}

3.2 Automatic removal of delete markers with no other versions

When an object has only one version as a delete marker, the latter can be automatically removed after a certain number of days using the following configuration:

{
    "Rules": [
        {
            "ID": "Removing all old versions",
            "Expiration": {
                "Days": 1,
                "ExpiredObjectDeleteMarker": true
            },
            "Status": "Enabled"
        }
    ]
}
