python - 在不使用命令行参数的情况下从 python 程序启动 celery beat

Question

我实现了一个启动 celery 的 python 命令

@click.command("tasks", help="run this command to start celery task queue")
def tasks():
    """
    Runs the celery task queue
    """
    from celery.bin import worker

    try:

        worker = worker.worker(app=app.config.get("task_app"))
        worker.run(app="my_app.task_queue", loglevel="info", uid=os.environ["uid"])
    except Exception as e:
        raise e

我需要创建一个类似的命令来启动 celery beat，我有以下方法

@click.command("beat", help="run this command to start beat")
def beat():

    try:


        p = app.config.get("task_app") # gets the current 
        command = CeleryCommand()
        lst = ["celery", "beat"]
        command.execute_from_commandline(lst)

    except Exception as e:
        raise e

--app 参数不适用于这种方法。有没有办法让这个命令以编程方式工作 celery -A proj beat 而不从命令行传递？

Answer 1

以编程方式启动 celery beat:

app.Beat(loglevel='debug').run()

或者:

from celery.apps.beat import Beat

b = Beat(app=your_celery_app, loglevel='debug')
b.run()

有关关键字参数，请参阅 celery.beat documentation 。
