如何更新 dockerized InvenTree

English Deutsch 简体中文

问题

在我们之前的文章如何在 5 分钟内使用 docker 安装 InvenTree 中，我们展示了一种使用 docker-compose 安装 InvenTree 的简单方法。在本文中，我们将向你展示如何更新你的 dockerized InvenTree 安装。

然而，如果你尝试从之前的版本升级此安装，启动将失败并显示一些与数据库相关的错误消息，如

inventree_traceback.txt
  File "/root/.local/lib/python3.11/site-packages/django/db/models/query.py", line 1881, in _fetch_all
    self._result_cache = list(self._iterable_class(self))

    with self.db.wrap_database_errors:

    raise dj_exc_value.with_traceback(traceback) from exc_value

解决方案

首先，停止你的 InvenTree 实例以执行更新过程，例如使用

inventree_down.sh
docker-compose down

然后，使用以下命令将 InvenTree docker 镜像更新到最新版本

inventree_update_and_migrate.sh
#!/bin/sh
docker-compose up -d inventree-cache inventree-db
docker-compose run inventree-server invoke update

此命令完成所有内置迁移到当前版本后，你可以使用以下命令再次启动 InvenTree 实例

inventree_start.sh
docker-compose up -d

示例输出
