# Introduction

SoftWare Repository for Container (SWR) allows you to easily manage the full lifecycle of container images and facilitates secure deployment of images for your applications.

SWR can either work with CCE or be used as an independent container image repository.

Figure 1 How SWR works

#### Features

- Full lifecycle management of images

  SWR manages the whole lifecycle of your container images, including push, pull, and deletion.

- Private image repository and access control

  Private image repository and fine-grained permission management allow you to grant different access permissions, namely, read, write, and edit, to different users.

- P2P acceleration of large scale image distribution

  SWR uses the image download acceleration technology to ensure faster image pull for CCE clusters in high concurrency scenarios.

#### Accessing SWR

The cloud platform provides a web-based management console and HTTPS-based APIs through which you can access the SWR service.

- Using APIs

  If you want to integrate SWR into a third-party system for secondary development, use APIs to access SWR. For details, see SWR API Reference.

- Using the management console

  Use this mode if you do not want to integrate SWR into a third-party system.
