# MinIO self-managed repository
[MinIO](https://min.io/docs/minio/container/index.html) is a popular, open-source object storage server compatible with the Amazon AWS S3 API. As an [S3 compatible service](/elastic/docs-content/pull/4236/deploy-manage/tools/snapshot-and-restore/s3-repository#repository-s3-compatible-services), MinIO is supported for use as a snapshot repository in Elastic Cloud Enterprise (ECE).
This guide walks you through integrating MinIO with ECE to store your Elasticsearch snapshots.
<important>
  Avoid running MinIO directly on ECE hosts. Sharing infrastructure can lead to resource contention, especially disk I/O, and may affect the performance and stability of your Elastic workloads. It also complicates upgrades, troubleshooting, and supportability.If you're evaluating MinIO in a test system, do not place MinIO containers on the same hosts as ECE proxies, as both services use the same port.
</important>


## Deploy MinIO

This section provides guidance and recommendations for deploying MinIO. It does not include installation steps. As MinIO is a third-party product, its deployment, configuration, and maintenance are outside the scope of Elastic support.
For installation instructions, refer to the official [MinIO documentation](https://min.io/docs/).
The performance and reliability of MinIO depend on its configuration and the underlying infrastructure. Consider the following best practices:
- For production use, deploy MinIO in a [Multi-Node Multi-Drive](https://min.io/docs/minio/linux/operations/install-deploy-manage/deploy-minio-multi-node-multi-drive.html#minio-mnmd) configuration.
- Use a single MinIO endpoint with the ECE installation, to simplify repository configuration.
- Secure access to the MinIO endpoint with TLS.

After deployment, make sure you collect the following values:
- MinIO Access Key
- MinIO Secret Key
- MinIO endpoint URL

<tip>
  MinIO may report multiple endpoint URLs. Be sure to select the one reachable from your Elasticsearch containers running on ECE allocator hosts.
</tip>


### Testing and evaluation

Use the [MinIO Quickstart Guide](https://charts.min.io/) or the [container deployment guide](https://min.io/docs/minio/container/index.html) to spin up a simple standalone MinIO container. Use `-v` to map persistent storage when using the `docker` or `podman` options.

### Production environments

Set up MinIO across multiple nodes and drives to ensure high availability, performance, and scalability, following the recommendations in the [MinIO documentation](https://min.io/docs/minio/linux/operations/install-deploy-manage/deploy-minio-multi-node-multi-drive.html).
You can use Docker Compose, Kubernetes, or another orchestration tool of your choice.

## Create the S3 bucket

After installing MinIO you will need to create a bucket to store your deployments' snapshots. Use the MinIO browser or an S3 client application to create an S3 bucket to store your snapshots.
<tip>
  Don’t forget to make the bucket name DNS-friendly, for example no underscores or uppercase letters. For more details, read the [bucket restrictions](https://docs.aws.amazon.com/AmazonS3/latest/dev/BucketRestrictions.html).
</tip>


## Elastic Cloud Enterprise configuration

This section describes the configuration changes required to use MinIO storage within ECE to make periodic snapshots of your deployments. The required steps include:
- Configuring the repository at ECE level
- Associating it with your deployments
- Applying specific YAML settings to the deployments


### Prerequisites

Before integrating ECE with MinIO, ensure you have the following details from your MinIO deployment:
- MinIO Access Key
- MinIO Secret Key
- MinIO endpoint URL
- S3 bucket name


### Add the repository to Elastic Cloud Enterprise

You must add the new repository at ECE platform level before it can be used by your Elasticsearch deployments.
1. [Log into the Cloud UI](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/deploy/cloud-enterprise/log-into-cloud-ui).
2. From the **Platform** menu, select **Repositories**.
3. Select **Add Repository**.
4. From the **Repository Type** drop-down list, select **Advanced**.
5. In the **Configuration** text area, provide the repository JSON. You must specify the bucket, access_key, secret_key, endpoint, and protocol.
   ```json
     {
        "type": "s3",
         "settings": {
            "bucket": "ece-backup",
            "access_key": "<your MinIO AccessKey>",
            "secret_key": "<your MinIO SecretKey>",
            "endpoint": "<your MinIO endpoint URL>:9000",
            "path_style_access": "true",
            "protocol": "http"
         }
     }
   ```
6. Select **Save** to submit your configuration.


### Associate repository with deployments

Once the MinIO repository is created at the ECE platform level, you can associate it with your Elasticsearch deployments in two ways:
- For new deployments, select the repository from the **Snapshot repository** drop-down list while [creating the deployment](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/deploy/cloud-enterprise/create-deployment).
- For existing deployments, associate the repository by following the instructions in [Manage Elasticsearch clusters repositories](/elastic/docs-content/pull/4236/deploy-manage/tools/snapshot-and-restore/cloud-enterprise#ece-manage-repositories-clusters).


### Additional settings for Elasticsearch

After selecting the repository, you also need to configure your [Elasticsearch user settings YAML](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/deploy/cloud-enterprise/edit-stack-settings-elasticsearch) to specify the endpoint and protocol. For example:
```
s3.client.default.endpoint: "<your MinIO endpoint>:9000"
s3.client.default.protocol: http
```

Refer to the [Elasticsearch S3 plugin details](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/tools/snapshot-and-restore/s3-repository) for more information.

#### Add S3 repository plugin (only for Elasticsearch 7.x)

For Elasticsearch clusters in version 7.x you must add the S3 repository plugin to your cluster. Refer to [Managing plugins for ECE](https://docs-v3-preview.elastic.dev/elastic/elasticsearch/tree/main/reference/elasticsearch-plugins/plugin-management#managing-plugins-for-ece) for more details.
<note>
  For versions 8.0 and later, Elasticsearch has built-in support for AWS S3 repositories; no repository plugin is needed.
</note>


## Verify snapshots

The cluster should make periodic snapshots when the repository is set up and associated to it. You can check this in the **Elasticsearch > Snapshots** section of the deployment page in the [Cloud UI](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/deploy/cloud-enterprise/log-into-cloud-ui).
As an extra verification step, you can [restore snapshots across clusters](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/tools/snapshot-and-restore/ece-restore-across-clusters).
Refer to [work with snapshots](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/4236/deploy-manage/tools/snapshot-and-restore) for more information around Elasticsearch snapshot and restore.
For additional considerations on performance, reliability, and troubleshooting when using MinIO as a snapshot repository, refer to [Using MinIO with Elasticsearch](/elastic/docs-content/pull/4236/deploy-manage/tools/snapshot-and-restore/s3-repository#using-minio-with-elasticsearch).
