# OpenHarmony Docker Image

### Docker Image

This document provides guidance on building the Docker image for mini- and small-system devices.

The Docker image of OpenHarmony is hosted on [HUAWEI Cloud SWR](https://auth.huaweicloud.com/authui/login.html?service=https%3A%2F%2Fconsole.huaweicloud.com%2Fswr%2F%3Fregion%3Dcn-south-1%26cloud_route_state%3D%2Fapp%2Fwarehouse%2FwarehouseMangeDetail%2Fgoldensir%2Fopenharmony-docker%2Fopenharmony-docker%3Ftype%3DownImage&locale=en-us#/login). Using the Docker image will help simplify environment configurations needed for the building. The following table lists container-based options needed for building in the standalone [Docker environment](https://gitee.com/openharmony/docs/blob/master/en/device-dev/get-code/gettools-acquire.md).
