Enable object lifecycle configuration on buckets to setup automatic deletion of objects after a specified number of days or a specified date.
- Install MinIO - MinIO Quickstart Guide.
- Install
mc- mc Quickstart Guide
- Create a bucket lifecycle configuration which expires the objects under the prefix
old/on2020-01-01T00:00:00.000Zdate and the objects undertemp/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"
}
]
}
EOFLifecycle configuration imported successfully to `play/testbucket`.
- List the current settings
$ mc ilm list play/testbucket

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