Question

当我运行docker-compose时，它只是挂起。我的代码的第一行是打印语句，但没有看到任何输出。 docker-compose

version: "3"
services:
  grip-sim-results-parser:
    container_name: grip-sim-results-parser
    build: .
    ports:
      - "5000:5000"

Dockerfile

FROM library/python:3.7-stretch
RUN apt-get update
RUN apt-get install -y vim
ADD . /code
WORKDIR /code
COPY requirements.txt /
RUN pip3 install --trusted-host pypi.org -r /requirements.txt

CMD ["python3", "app.py"]

Answer 1

要查看python的输出，请尝试向docker-compose.yml添加以下行：

grip-sim-results-parser:
  environment:
    - PYTHONUNBUFFERED=1

docker-compose在附加后挂起
