Celery kombu.exceptions.ContentDisallowed in Docker

Question

我正在使用帶有 fastAPI 的 celery。

在docker . 在沒有 docker 的本地機器上運行相同的程序時，沒有問題。

相同的配置如下。

celery_app = Celery('cda-celery-tasks',
                    broker=CFG.BROKER_URL,
                    backend=CFG.BACKEND_URL,
                    include=['src.tasks.tasks']
                    )

celery_app.conf.task_serializer = 'pickle'
celery_app.conf.result_serializer = 'pickle'
celery_app.conf.accept_content = ['pickle']
celery_app.conf.enable_utc = True

在 docker 中運行時，我不斷收到錯誤消息

FROM python:3.8
WORKDIR /app

COPY . .

RUN pip3 install poetry
ENV PATH="/root/.poetry/bin:$PATH"

RUN poetry install

使用 kubernetes 中的以下命令啟動 celery。

poetry run celery -A src.infrastructure.celery_application worker --loglevel=INFO --concurrency 2

運行時我不斷收到錯誤

無法解碼消息正文：ContentDisallowed('拒絕反序列化 json (application/json) 類型的不受信任的內容')

    raise self._for_untrusted_content(content_type, 'untrusted')

有人可以告訴我管理相同問題的可能原因和解決方案嗎？ 如果我遺漏了任何內容，過分強調或過分強調某一點，請在評論中告訴我。 非常感謝您抽出寶貴時間。

使用 accept_content 類型配置 celery_app 似乎可以解決問題：

celery_app.conf.accept_content = ['application/json', 'application/x-python-serialize', 'pickle']
