Docker 中的 Celery kombu.exceptions.ContentDisallowed

Question

我正在使用 celery 和 fastAPI。

获取无法解码消息正文：ContentDisallowed('拒绝反序列化 json 类型的不受信任内容 (application/json)')在 docker 中运行时，在没有 docker 的本地计算机上运行相同的内容时，没有问题。

其配置如下。

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 中运行时，我不断收到错误

FROM python:3.8
WORKDIR /app

COPY . .

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

RUN poetry install

使用 kubernetes 中的以下命令启动 celery。

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

运行时我不断收到错误

无法解码消息正文：ContentDisallowed('拒绝反序列化 json 类型的不受信任内容 (application/json)')

    raise self._for_untrusted_content(content_type, 'untrusted')
kombu.exceptions.ContentDisallowed: Refusing to deserialize untrusted content of type json (application/json)

有人可以告诉我可能的原因和解决方案吗？如果我遗漏了任何内容，过度或低估了某个特定点，请在评论中告诉我。非常感谢您抽出时间。

使用accept_content类型配置celery_app似乎可以解决这个问题：

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