芹菜节拍立即停止，出现资源错误

Question

芹菜节拍的日志是这样的，最后一行刚刚停止，不再继续和恢复。

它在 docker 容器内运行。当我通过顶部检查时，它显示高 CPU 百分比

然后当我在容器内ssh并尝试使用芹菜节拍命令时。以下错误最初返回

请注意，我只使用纯芹菜，而不是姜戈芹菜节拍

我亲爱的朋友，当你每个你的docker容器时，celery想要创建celerybeat.pid文件，如果存在django会引发错误。因此，您应该添加以下命令以删除Dockerfile上的当前celerybeat.pid文件，如下所示：

COPY entrypoint.sh /code/entrypoint.sh
ENTRYPOINT ["/code/entrypoint.sh"]
RUN chmod +x /entrypoint.sh

您应该创建一个 entrypoint.sh 文件，如下所示：

#!/bin/sh
rm -rf /code/badpanty/*.pid
exec "$@"

我希望它对您有所帮助。
