+## 磁盘挂载
+如果想要将容器中的数据持久化保存下来，通常的做法是在`run` docker镜像时，使用 `-v /host/path:/container/path` 的方式将数据保存在宿主机上。
+oceanbase-ce镜像的数据库数据默认保存在/root/ob目录下。但是仅仅映射/root/ob目录，会导致新的镜像无法启动，因为oceanbase-ce镜像是使用[obd](https://github.com/oceanbase/obdeploy) 来管理集群的，新的镜像启动时，没有oceanbase的集群信息，所以需要同时挂载/root/ob和/root/.obd目录。
+挂载目录运行示例：
+
+```bash
+docker run -d -p 2881:2881 -v $PWD/ob:/root/ob -v $PWD/obd:/root/.obd --name oceanbase oceanbase/oceanbase-ce
+```
+
+注意需要按照实际情况调整自己的目录。
+docker -v 参数的详细说明可以参考 [docker volumn](https://docs.docker.com/storage/volumes/)

+## Mount Volumn
+You can use `-v /host/path:/container/path` parameter in docker `run` command to save data in host os if you want to persistence the data of a container.
+
+The docker image `oceanbase-ce` save the data to /root/ob directory default. You can not start a new docker image if you only bind the /root/ob directory, because the docker image oceanbase-ce use the [obd](https://github.com/oceanbase/obdeploy) to manage database clusters and there is no information about the database cluster after a new docker image started. So you should bind both the /root/ob and /root/.obd directory.
+
+Below is an example.
+
+```bash
+docker run -d -p 2881:2881 -v $PWD/ob:/root/ob -v $PWD/obd:/root/.obd --name oceanbase oceanbase/oceanbase-ce
+```
+
+Note that you should use your own path.
+
+You can view more information about `docker -v` at [docker volumn](https://docs.docker.com/storage/volumes/).
