问题描述

在Docker容器中搭建新的Odoo开发实例，使用外部生产实例的数据完成数据库迁移后，启动时出现附件文件找不到的错误。

已执行的数据库迁移步骤：

sudo docker cp dump.sql db_docker_name:/dump.sql  

sudo docker exec -it --user postgres db_docker_name /bin/bash 

psql database_name < dump.sql  

ALTER DATABASE database_name OWNER TO odoo; 

sudo docker exec docker_name pip3 install xmlschema # 及其他依赖

启动后报错信息：

容器内filestore/dblive目录内容：

odoo@95198003ea0a:~/filestore/dblive$ ls

解决方案

报错核心是数据库中记录的附件文件未同步到开发容器的filestore目录，仅迁移数据库不足以完整复制Odoo实例数据，必须同步filestore目录。按以下步骤操作：

从生产实例同步filestore目录到本地
假设生产实例的filestore路径为/var/lib/odoo/filestore/dblive，用scp复制到本地：
```
scp -r user@生产服务器IP:/var/lib/odoo/filestore/dblive ./local-filestore
```
将本地filestore上传到开发容器
用docker cp将目录复制到容器对应的路径：
```
sudo docker cp ./local-filestore docker_name:/var/lib/odoo/filestore/
```

修正容器内filestore的权限
确保Odoo用户拥有目录读写权限：

sudo docker exec -it docker_name chown -R odoo:odoo /var/lib/odoo/filestore/dblive

重启Odoo容器
```
sudo docker restart docker_name
```

如果生产实例也是Docker容器，可直接在容器间复制：

sudo docker cp 生产容器名:/var/lib/odoo/filestore/dblive ./local-filestore
sudo docker cp ./local-filestore 开发容器名:/var/lib/odoo/filestore/
