## Upgrading MinIO

Upgrades require zero downtime in MinIO, all upgrades are non-disruptive, all transactions on MinIO are atomic. So upgrading all the servers simultaneously is the recommended way to upgrade MinIO.

To override a setting that includes dots, escape them with a backslash (\).  Your shell may require enclosing quotes.

``` bash
istioctl manifest generate --set "values.sidecarInjectorWebhook.injectedAnnotations.container\.apparmor\.security\.beta\.kubernetes\.io/istio-proxy=runtime/default"
```

```bash
helm install --set existingSecret=my-minio-secret minio/minio
```

The following fields are expected in the secret:

| .data.\<key\> in Secret | Corresponding variable | Description    | Required |
|:------------------------|:-----------------------|:---------------|:---------|
| `rootUser`              | `rootUser`             | Root user.     | yes      |

    * As the `q` parameter is declared with `= None`, it is optional.
    * Without the `None` it would be required (as is the body in the case with `PUT`).
* For `PUT` requests to `/items/{item_id}`, Read the body as JSON:
    * Check that it has a required attribute `name` that should be a `str`.
    * Check that it has a required attribute `price` that has to be a `float`.
