dockercompose up在连接到时卡住

Question

我已经编写了几个python脚本，可以对交易策略进行回溯测试。我正试图通过docker compose部署这些

feeder容器将测试文件复制到一个工作目录中，backtester容器将在该目录中拾取并处理它们。然后将处理后的测试文件发送到“已完成的工作”文件夹。backtester输出的一些CSV文件随后会写入另一台计算机上的NFS共享。我应该提到的是，这些都是在Ubuntu 20.04上运行的

据我所知，一切正常，但由于某种原因，“docker compose up”命令挂起“Attaching to”。应该有打印语句的进一步输出（我已经取消了DockerFile的缓冲，所以这些应该会显示出来）。我还让它运行了一段时间，看看是否有任何东西正在被处理，看起来容器从未启动过。我查看了所有其他处理此问题的线程，但没有找到解决此问题的解决方案

任何洞察都是非常感谢的。谢谢

以下是docker compose文件：

version: '3.4'

services:
  feeder:
    image: feeder
    build:
      context: .
      dockerfile: ./Dockerfile.feeder
    volumes:
      - /home/danny/io:/var/lib/io
  worker1:
    image: backtester
    build:
      context: .
      dockerfile: ./Dockerfile
    volumes:
      - /home/danny/io/input/workers/worker1:/var/lib/io/input
      - /home/danny/io/input/completedwork:/var/lib/io/archive
      - /nfs/tests:/var/lib/tests
  worker2:
    image: backtester
    build:
      context: .
      dockerfile: ./Dockerfile
    volumes:
      - /home/danny/io/input/workers/worker2:/var/lib/io/input
      - /home/danny/io/input/completedwork:/var/lib/io/archive
      - /nfs/tests:/var/lib/tests
  worker3:
    image: backtester
    build:
      context: .
      dockerfile: ./Dockerfile
    volumes:
      - /home/danny/io/input/workers/worker3:/var/lib/io/input
      - /home/danny/io/input/completedwork:/var/lib/io/archive
      - /nfs/tests:/var/lib/tests

以下是backtester的Dockerfile：

# For more information, please refer to https://aka.ms/vscode-docker-python
FROM python:3.8-slim-buster

# Keeps Python from generating .pyc files in the container
ENV PYTHONDONTWRITEBYTECODE=1

# Turns off buffering for easier container logging
ENV PYTHONUNBUFFERED=1

# Install pip requirements
COPY requirements.txt .
RUN python -m pip install -r requirements.txt

WORKDIR /app
COPY . /app

# Creates a non-root user with an explicit UID and adds permission to access the /app folder
# For more info, please refer to https://aka.ms/vscode-docker-python-configure-containers
# RUN adduser -u 5678 --disabled-password --gecos "" appuser && chown -R appuser /app
# USER appuser

CMD ["python", "backtester5.py"]

已经三周没有回复了，但我只是想用我的发现更新一下。在我让“docker compose up”运行的所有情况下，它最终都会启动

有时需要30分钟，但每次都要开始
