### 1.6 KingbaseES 人大金仓

① 下载人大金仓 Docker 镜像:

|

|

② 加载镜像文件,在镜像 tar 文件所在目录运行:
|

|
||||
```Bash
|

docker load -i x86_64/kdb_x86_64_V009R001C001B0025.tar

```

③ 在项目 `sql/tools` 目录下运行:
|

|

```Bash
|
||||
docker compose up -d kingbase
|
||||
# 注意:启动完 dm 后,需要手动再执行如下命令,因为 dm 不支持初始化脚本
|
||||
docker compose exec kingbase bash -c "exec ksql -Uroot -d test -f /tmp/schema.sql"
|
||||
```
|
||||
|
||||
**注意**: MyBatis, MyBatis Plus 目前不兼容人大金仓,推荐直接使用PostgreSQL JDBC 驱动,已经 url 配置方式连接数据库。

## 1.X 容器的销毁重建
|
||||
|
||||
开发测试过程中,有时候需要创建全新干净的数据库。由于测试数据 Docker 容器采用数据卷 Volume 挂载数据库实例的数据目录,因此销毁数据需要停止容器后,删除数据卷,然后再重新创建容器。
