 `oceanbase-ce` docker默认会将数据保存到 /root/ob 目录。必须同时绑定 /root/ob 和 /root/.obd 目录。如果仅仅绑定 /root/ob 目录的话，容器就没办法重启了，因为oceanbase-ce 是使用 [obd](https://github.com/oceanbase/obdeploy)来管理数据库集群的，而启动一个全新的docker容器时，里面没有任何数据库集群信息。
 
 docker -v 参数的详细说明可以参考 [docker volumn](https://docs.docker.com/storage/volumes/)。

+## 快速单机启动镜像构建
+在`tools/docker/standalone`目录下提供`fast_boot_docker_build.sh`脚本，通过该脚本可以构建快速启动镜像。在运行脚本之前，请首先修改`tools/docker/standalone/boot/_env`环境配置脚本：
+
+- 必须：将`MODE`配置项修改为`STANDALONE`
+- 可选：修改其余配置项
+
+修改完毕后，执行镜像构建脚本，目前支持使用远程RPM包构建以及本地编译生成的RPM包两种方式：
+
+- 本地：`./fast_boot_docker_build.sh -L <oceanbase_rpm_path> <oceanbase_lib_rpm_path>`
+- 远程：`./fast_boot_docker_build.sh -R <remote_rpm_version>`
+
+等待构建完毕后，可使用前述相同的方式启动、测试实例。

 The docker image `oceanbase-ce` saves the data to /root/ob directory default. You should bind both the /root/ob and /root/.obd. You can not start new docker image if you only bind the /root/ob directory, because the docker image oceanbase-ce uses the [obd](https://github.com/oceanbase/obdeploy) to manage database clusters and there is no information about the database cluster in a new docker container.
 
 You can view more information about `docker -v` at [docker volume](https://docs.docker.com/storage/volumes/).

+## Fast boot image building for a standalone node
+The `fast_boot_docker_build.sh` script is provided in the `tools/docker/standalone` directory, through which the fast boot image can be built. Before running the script, please first modify the `tools/docker/standalone/boot/_env` environment configuration script:
+
+- Required: Modify the `MODE` configuration item to `STANDALONE`
+- Optional: Modify the remaining configuration items
+
+After the modification is completed, execute the image build script. Currently, two methods are supported: building with remote RPM packages and building with RPM packages generated by local compilation:
+
+- Local: `./fast_boot_docker_build.sh -L <oceanbase_rpm_path> <oceanbase_lib_rpm_path>`
+- Remote: `./fast_boot_docker_build.sh -R <remote_rpm_version>`
+
+After waiting for the build to be completed, you can start and test the instance in the same way as mentioned above.
