docker-compose up 卡在附加到

Question

我编写了几个 Python 脚本来回测交易策略。我正在尝试通过 docker compose 部署这些。

馈送容器将测试文件复制到工作目录，回测器容器将在工作目录中拾取并处理它们。然后，处理后的测试文件被发送到“已完成的工作”文件夹。然后，回测器输出的一些 CSV 文件会写入另一台计算机上的 NFS 共享。我应该提到的是，这一切都在 Ubuntu 20.04 上运行。

据我所知，一切都应该正常工作，但由于某种原因，“docker-compose up”命令挂在“附加到”上。应该有带有 print 语句的进一步输出（我已经取消缓冲 Dockerfile，因此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处理，看起来容器从未启动过。我已经查看了处理此问题的所有其他线程，但尚未找到可以解决此问题的解决方案。

任何见解都非常非常感谢。谢谢。

这是 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

这是回测器的 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

这是 feeder 的 Dockerfile：

已经三周了，没有任何回复，但我只是想更新我所发现的内容。在所有我让“docker-compose up”运行的情况下，它最终都会启动。

有时要花30分钟，但每次都会开始。
