You can use Helm to update MinIO version in a live release. Assuming your release is named as `my-release`, get the values using the command:

```bash
helm get values my-release > old_values.yaml
```

Then change the field `image.tag` in `old_values.yaml` file with MinIO image tag you want to use. Now update the chart using

```bash
helm upgrade -f old_values.yaml my-release minio/minio
```

Follow below steps to get started with MinIO monitoring using Prometheus.

### 1. Download Prometheus

[Download the latest release](https://prometheus.io/download) of Prometheus for your platform, then extract it

```sh
tar xvfz prometheus-*.tar.gz
cd prometheus-*
```

> NOTE: If you are using a mc version below `RELEASE.2022-12-24T15-21-38Z`, the --remote-bucket flag needs an ARN generated by `mc admin bucket remote add` command. For  mc versions RELEASE.2021-09-02T09-21-27Z and older, the remote target ARN needs to be passed in the --arn flag and actual remote bucket name in --remote-bucket flag of  `mc replicate add`. For example, in older releases of mc replication configuration used to be added with:

```

> database            (string)             database name (used only if `connection_string` is empty)
> ```
>
> These are now deprecated, if you plan to upgrade to any releases after _RELEASE.2020-04-10T03-34-42Z_ make sure
> to migrate to only using _connection_string_ option. To migrate, once you have upgraded all the servers use the
> following command to update the existing notification targets.
>

- Chroot installed on your machine.

## 2. Install MinIO in Chroot

```sh
mkdir -p /mnt/export/${USER}/bin
wget https://dl.min.io/server/minio/release/linux-amd64/minio -O /mnt/export/${USER}/bin/minio
chmod +x /mnt/export/${USER}/bin/minio
```

Bind your `proc` mount to the target chroot directory

```
sudo mount --bind /proc /mnt/export/${USER}/proc
```

* MinIO doesn't currently support PFX certificates.

### 3.1 Use `certgen` to Generate a Certificate

Download [`certgen`](https://github.com/minio/certgen/releases/latest) for your specific operating system and platform.

`certgen` is a simple *Go* tool to generate self-signed certificates, and provides SAN certificates with DNS and IP entries:

```sh

mc mb myminio/functionbucket
```

Create a file `testobject` with some test data that will be transformed
```
cat > testobject << EOF
MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0. It is API compatible with Amazon S3 cloud storage service. Use MinIO to build high performance infrastructure for machine learning, analytics and application data workloads.

```

### Notes

* By default the Docker Compose file uses the Docker image for latest MinIO server release. You can change the image tag to pull a specific [MinIO Docker image](https://hub.docker.com/r/minio/minio/).
