## Introduction

This chart bootstraps MinIO Cluster on [Kubernetes](http://kubernetes.io) using the [Helm](https://helm.sh) package manager.

## Prerequisites

- Helm cli with Kubernetes cluster configured.

Менеджер контексту в Python - це те, що можна використовувати в операторі `with`, наприклад, `open()` можна використовувати як менеджер контексту:

```Python
with open("file.txt") as file:
    file.read()
```

У новіших версіях Python також є асинхронний менеджер контексту. Його використовують з `async with`:

```Python
async with lifespan(app):
    await do_stuff()
```

        return IndexedImmutableSet.this;
      }
