 This section describes the steps to compile and use OpenMLDB inside its official docker image [hybridsql](https://hub.docker.com/r/4pdosc/hybridsql).
 The docker image has packed required tools and dependencies, so there is no need to set them up separately. To compile without the official docker image, refer to the section [Detailed Instructions for Build](#detailed-instructions-for-build) below.

If the user wishes to compile by himself (for example, for OpenMLDB source code development, the operating system or CPU architecture is not in the support list of the precompiled deployment package, etc.), the user can choose to compile and use in the docker container or compile from the source code.

 此节介绍在官方编译镜像 [hybridsql](https://hub.docker.com/r/4pdosc/hybridsql) 中编译 OpenMLDB，主要可以用于在容器内试用和开发目的。镜像内置了编译所需要的工具和依赖，因此不需要额外的步骤单独配置它们。关于基于非 docker 的编译使用方式，请参照下面的 [从源码全量编译](#从源码全量编译) 章节。
 
-对于编译镜像的版本，需要注意拉取的镜像版本和 [OpenMLDB 发布版本](https://github.com/4paradigm/OpenMLDB/releases)保持一致。以下例子演示了在 `hybridsql:0.8.1` 镜像版本上编译 [OpenMLDB v0.8.1](https://github.com/4paradigm/OpenMLDB/releases/tag/v0.8.1) 的代码，如果要编译最新 `main` 分支的代码，则需要拉取 `hybridsql:latest` 版本镜像。
