OSError：在Docker中初始化Celery时，权限被拒绝

运行docker撰写时，出现以下错误。 这个问题在我的Mac OS开发环境中完全没有发生（在Ubuntu和debian中尝试部署时发生这个错误），但是这个错误似乎表明Celery没有权限写入celerybeat文件。 我一直在努力试图让这个工作（试图给予芹菜必要的权限），但没有运气。

对于那些有相同问题的人可以通过给芹菜用户写入celerybeat文件的权限来解决这个问题。 我首先能够通过在Filezilla中手动设置文件权限来解决这个问题。 如果你想在你的dockerfile中自动执行这个操作，你可以将下面的代码附加到文件的底部：

 USER root RUN sudo chown -R celery:celery celerybeat-schedule 

并确保先使用以下代码片段安装sudo：

 RUN apt-get -y install sudo
