我一直在广泛搜索，到目前为止我遇到的一切都表明我的配置是正确的......我可以看到我的任务正在我的 celery worker 容器中注册。我没有看到它们在我的节拍容器中注册(但我认为我应该？我应该只看到我所做的任务)但任务没有运行。

最佳答案
您的 docker-compose.yml没有任何 MySQL 链接。您的应用程序是否可能无法访问数据库服务器？
如果您怀疑这是问题所在，您可以使用 docker ps 列出 docker 容器。然后手动尝试从相关容器内部使用 docker exec -ti <containerid> bash 连接到所需的数据库然后使用 mysql甚至 nc或 curl或 wget检查是否可以解析数据库主机 - 如果不能，请从 docker-compose.yml 链接到它将其插入 hosts文件自动，或者您可以手动完成，或者只是在您的配置文件中更新它。
