+# 如何使用这个镜像
+
+部署 OceanBase 数据库的方式有很多，使用 Docker 是其中较方便的一种。本仓库提供了 OceanBase 数据库的 Docker 镜像 obce-mini。obce-mini 是 OceanBase 数据库社区版的小规格单机体验镜像，仅供研究、学习和评估使用，不适用于生产环境或性能测试场景。
+
+## 前提条件
+
+在部署 obce-mini 镜像之前，您需要确认以下信息：
+
+- 确保您的机器至少提供 2 核 10GB 以上的资源。
+- 您的机器已经安装以下程序：
+
+    应用程序 | 推荐版本 | 参考文档
+    ---     | ------  | -----
+    Docker | 最新版 | [Docker 文档](https://docs.docker.com/get-docker/)
+- 您的机器已经启动 Docker 服务。
+
+## 启动 OceanBase 实例
+
+运行以下命令，启动 OceanBase 的实例：
+
+```bash
+docker run -p 2881:2881 --name some-obce -d oceanbase/obce-mini
+```
+
+启动预计需要 2-5 分钟。执行以下命令，如果返回 `boot success!`，则启动成功。
+
+```bash
+$ docker logs some-obce | tail -1
+boot success!
+```
+
+## 连接 OceanBase 实例
+
+obce-mini 镜像安装了 OceanBase 数据库客户端 obclient，并提供了默认连接脚本 ob-mysql。
+
+```bash
+docker exec -it some-obce ob-mysql sys # 连接 sys 租户
+docker exec -it some-obce ob-mysql root # 连接用户租户的 root 账户
+docker exec -it some-obce ob-mysql test # 连接用户租户的 test 账户
+```
+
+您也可以运行以下命令，使用您本机的 obclient 或者 MySQL 客户端连接实例。
+
+```bash
+$mysql -uroot -h127.1 -P2881
+```
+
+连接成功后，终端将显示如下内容：
+
+```mysql
+Welcome to the MySQL monitor.  Commands end with ; or \g.
+Your MySQL connection id is 167310
+Server version: 5.7.25 OceanBase 3.1.0 (r-00672c3c730c3df6eef3b359eae548d8c2db5ea2) (Built Jun 22 2021 12:46:28)

+```
+
+## 支持的环境变量
+
+下表列出了当前版本的 obce-mini 镜像支持的环境变量：
+
+变量名称 | 默认值 | 描述
+------- | ----- | ---
+OB_HOME_PATH | /root/ob | OceanBase 数据库实例的部署路径。
+OB_MYSQL_PORT | 2881 | OceanBase 数据库实例的 MySQL 协议端口。
+OB_RPC_PORT | 2882 | OceanBase 数据库实例的 RPC 通信端口。
+OB_ROOT_PASSWORD | empty |  OceanBase 数据库实例 sys 租户的密码。
+OB_CLUSTER_NAME | mini-ce | OceanBase 数据库实例名称，OBD 将使用这个名称作为集群名。
+OB_TENANT_NAME | test | OceanBase 数据库实例默认初始化的用户租户的名称。
+
+## 运行 Sysbench 脚本
+
+obce-mini 镜像默认安装了 Sysbench 工具，并进行了简单配置。您可以依次执行以下命令，使用默认配置运行 Sysbench 脚本。
+
+```bash
+docker exec -it some-obce sysbench cleanup # 清理数据
+docker exec -it some-obce sysbench prepare # 准备数据
+docker exec -it some-obce sysbench run # 进行测试
+
+docker exec -it some-obce sysbench # 依次执行上述三条命令
+```
+

+# How to use this image
+
+You can deploy OceanBase databases by using many methods. But Docker is the easiest method. This repository gives you an obce-mini image for deploying OceanBase database by using Docker. obce-mini is a mini standalone test image for OceanBase Database Community Edition. You can use it only for research/study/evaluation.  DO NOT use it for production or performance testing.
+
+## Prerequisite
+
+Before you deploy obce-mini image, do a check of these:
+
+- Make sure that your machine has at least 2 physical core and 10GB memory.
+- Your machine has installed these applications:
+
+    Application | Recommended version | Documentation
+    ---     | ------  | -----
+    Docker | Latest | [Docker Documentation](https://docs.docker.com/get-docker/)
+- You have started the Docker service on your machine.
+
+## Start an OceanBase instance
+
+To start an OceanBase instance, run this command:
+
+```bash
+docker run -p 2881:2881 --name some-obce -d oceanbase/obce-mini
+```
+
+Two to five minutes are necessary for the boot procedure. To make sure that the boot procedure is successful, run this command:
+
+```bash
+$ docker logs some-obce | tail -1
+boot success!
+```
+
+## Connect to an OceanBase instance
+
+obce-mini image contains obclient (OceanBase Database client) and the default connection script `ob-mysql`.
+
+```bash
+docker exec -it some-obce ob-mysql sys # Connect to sys tenant
+docker exec -it some-obce ob-mysql root # Connect to the root account of a general tenant
+docker exec -it some-obce ob-mysql test # Connect to the test account of a general tenant
+```
+
+Or you can run this command to connect to an OceanBase instance with your local obclient or MySQL client.
+
+```bash
+$mysql -uroot -h127.1 -P2881
+```
+
+When you connect to an OceanBase instance successfully, the terminal returns this message:
+
+```mysql
+Welcome to the MySQL monitor.  Commands end with ; or \g.
+Your MySQL connection id is 167310
+Server version: 5.7.25 OceanBase 3.1.0 (r-00672c3c730c3df6eef3b359eae548d8c2db5ea2) (Built Jun 22 2021 12:46:28)

+```
+
+## Supported environment variables
+
+This table shows the supported environment variables of the current obce-mini mirror version:
+
+Variable name | Default value | Description
+------- | ----- | ---
+OB_HOME_PATH | /root/ob | Home path for an OceanBase Database instance.
+OB_MYSQL_PORT | 2881 | The MySQL protocol port for an OceanBase Database instance.
+OB_RPC_PORT | 2882 | The RPC communication port for an OceanBase Database instance.
+OB_ROOT_PASSWORD | empty |  The password for the system tenant in an OceanBase Database instance.
+OB_CLUSTER_NAME | mini-ce | Instance name for OceanBase Database instance. OBD uses this value as its cluster name.
+OB_TENANT_NAME | test | The default initialized general tenant name for an OceanBase Database instance.
+
+## Run the Sysbench script
+
+obce-mini image installs the Sysbench tool by default. And the Sysbench tool is configured. You can run these commands in sequence to run the Sysbench script with the default configurations.
+
+```bash
+docker exec -it some-obce sysbench cleanup # Clean the data
+docker exec -it some-obce sysbench prepare # Prepare the data
+docker exec -it some-obce sysbench run # Do the test
+
+docker exec -it some-obce sysbench # Run the preceding three commands in order
+```
