docker-compose up非常慢但是docker-compose在linux上运行非常快-Java 学习之路

-1

正如 Headers 所说 . Docker-Compose在运行容器时非常慢 . 当我运行“ docker-compose up ”时，它一直在说它正试图附加... python脚本运行大约需要10分钟 .

另一方面..如果我开始“ docker-compose run docker-build ”，python脚本会在一秒钟内运行 .

如果我使用“ docker run --rm -it Name_of_docker_image ”，python脚本也会在一秒钟内运行 .

Why do i need to wait 10 minutes before it start the python script with docker-compose up?

问题是因为缓冲日志 . 你应该改变

CMD ["/usr/bin/python", "run.py"]

至

CMD ["/usr/bin/python", "-u", "run.py"]

或者你应该更新你的 docker-compose.yml

version: "3"
services:
  docker-build:
    build: ./
    ports:
    - "4242:5000"
    environment:
      - "PYTHONUNBUFFERED=1"
