Question

我正在使用docker-compose运行三个容器。其中两个取决于数据库，因此我使用wait-for-it.sh来确保它们在数据库侦听之前不会运行。

这是my docker-compose.yml文件：

  web:
    build: ./docker/web
    command: ["./wait-for-it.sh", "db:5432", "--", "python", "manage.py", "runserver", "0.0.0.0:8080"]
    ports:
      - "8080:8080"
    depends_on:
      - db
      - spider
    links:
      - db

当我运行docker-compose up命令时收到错误消息：

web_1     | wait-for-it.sh: waiting 15 seconds for db:5432
web_1     | wait-for-it.sh: db:5432 is available after 0 seconds
web_1     | python: can't open file 'manage.py': [Errno 2] No such file or directory

当我添加卷.:/src时，找到了manage.py但没有wait-for-it.sh：

ERROR: for web  Cannot start service web: OCI runtime create failed: container_linux.go:345: starting container process caused "exec: \"./wait-for-it.sh\": stat ./wait-for-it.sh: no such file or directory": unknown

我将wait-for-it.sh文件添加到了web服务的Dockerfile所在的目录中。

有什么主意我该如何做？

编辑这是docker-compose中使用的Dockerfile：

FROM python:3.6
ENV PYTHONUNBUFFERED 1
RUN mkdir /src
COPY . /src
WORKDIR /src
RUN pip install -r requirements.txt

我通过更改方法修复了它。向数据库服务添加了运行状况检查：

healthcheck:
  test: ["CMD", "curl", "-f", "http://localhost:5432"]
  interval: 5s
  timeout: 30s
  retries: 5

并重新启动对其他服务的策略：

restart: on-failure

Docker-compose python manage.py没有这样的文件或目录
