我正在为我的Flask应用程序使用celery beat和docker运行定期的celery任务。但是，当我运行容器时，出现以下错误：
Removing corrupted schedule file 'celerybeat-schedule': error(22, 'Invalid argument')
Traceback (most recent call last):
File "/usr/local/lib/python3.7/site-packages/kombu/utils/objects.py", line 42, in __get__
return obj.__dict__[self.__name__]
KeyError: 'scheduler'
我像这样在settings.py中定义我的节拍调度程序：
CELERYBEAT_SCHEDULE = {
'fetch-expensify-reports': {
'task': 'canopact.blueprints.carbon.tasks.fetch_reports',
'schedule': 10.0
}
}
此配置被传递到我的create_celery_app文件中的app.py函数中：
def create_celery_app(app=None):
"""
Create a new Celery object and tie together the Celery config to the app's
config. Wrap all tasks in the context of the application.
:param app: Flask app
:return: Celery app
"""
app = app or create_app()
celery = Celery(app.import_name, broker=app.config['CELERY_BROKER_URL'],
include=CELERY_TASK_LIST)
celery.conf.update(app.config)
TaskBase = celery.Task
class ContextTask(TaskBase):
abstract = True
def __call__(self, *args, **kwargs):
with app.app_context():
return TaskBase.__call__(self, *args, **kwargs)
celery.Task = ContextTask
return celery
我试图像这样在docker-compose.yml文件中拆分芹菜工作者和芹菜节拍时间表：
celery:
build: .
command: celery worker -l info -A canopact.blueprints.contact.tasks
env_file:
- '.env'
volumes:
- '.:/canopact'
celery_beat:
build: .
command: celery beat -l info -A canopact.blueprints.contact.tasks
env_file:
- '.env'
volumes:
- '.:/canopact'
但是我遇到同样的问题。我还试图删除我的celerybeat计划文件，根据其他帖子的建议，该文件似乎已损坏。但是，在运行docker-compose up后，将再次创建该文件，并引发相同的错误。
我正在使用芹菜4.3.0。下面是尝试启动容器时的完整追溯。

这很奇怪，我现在还没有解决方案，但是我找到了一种解决方法。
为什么会出现问题：
[关于celery docs的一些想法解释了这里发生的事情：
节拍需要将任务的最后运行时间存储在本地数据库文件（默认名称为celerybeat-schedule），因此需要可以在当前目录中进行写操作，或者可以指定此文件的自定义位置：
Basicaly celery正在尝试读取名为celerybeat-schedule]的文件，但由于某种原因而导致失败。
为什么它无法在docker上读取它？
我暂时不知道...
但是此评论对give some灯
与文件存储有关。
这是我的解决方法。
[我决定使用Redis作为任务的调度程序运行时间，而不是文件存储，幸运的是，我发现this package可以帮助我实现这一目标。
您可以做的是这个：
使用：更新您的celery应用程序配置：
app.conf.redbeat_redis_url = your redis url然后您需要在docker文件中告诉celery应该使用哪个调度程序。
