# Bucket Lifecycle Configuration Quickstart Guide [](https://slack.min.io) [](https://hub.docker.com/r/minio/minio/)
|
|
|
|
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](https://docs.min.io/docs/minio-quickstart-guide).
|
|
- Install `mc` - [mc Quickstart Guide](https://docs.minio.io/docs/minio-client-quickstart-guide.html)
|
|
|
|
## 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": [
|
|
{
|
|
"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 list 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](https://docs.min.io/docs/minio-bucket-versioning-guide.html) 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"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
