# CloudKit.Container

A CloudKit.Container object provides access to an app container, and through the app container, access to its databases. It also contains methods for authenticating and fetching users.

## Declaration

```data
interface CloudKit.Container
```

## Overview

Overview You do not create container objects yourself, nor should you subclass the CloudKit.Container class. You configure a container using the CloudKit.configure method and obtain a container using one of the CloudKit namespace container methods. The asynchronous methods in this class return a Promise object that resolves when the operation completes. For a description of the Promise class returned by these methods, go to Mozilla Developer Network: Promise. This class is similar to the CKContainer class in the CloudKit framework.
