当运行来自 docker 的芹菜时失败

Question

我正在尝试让 celery 与 Django 和 docker 一起工作，并且该建筑运行良好，但我的 celery 不会运行。有什么想法吗？

这是 docker-compose logs -f 个错误

更新：添加了 docker-compose.yml 文件以更好地参考堆栈问题。构建成功但是当运行ning docker-compose up 它没有并抛出芹菜错误

我不确定它是否适用于您的情况，但在 docker 中，我使用以下命令启动芹菜：

command: celery -A my_proj worker -l DEBUG

因为它给你的错误是“exec format error”，所以可能就是这个。
