Docker-Compose +命令 [英] Docker-Compose + Command

问题描述

看来我的docker-compose命令只执行最后一个命令.在这种情况下，运行服务器.

It seems my docker-compose commands only execute the last command. In this case runserver.

command: python3 manage.py collectstatic --noinput
command: python3 manage.py migrate --noinput
command: python3 manage.py runserver 0.0.0.0:8000

我试图将这些命令移到entrypoint.sh文件中.但是，我不知道如何在我的dockerfile&中实现它.docker-compose.

I tried to move these commands into an entrypoint.sh file. However, I can't figure out how to implement this into my dockerfile & docker-compose.

以下是我的dockerfile:

The following is my dockerfile:

# Pull base image
FROM python:3

# Set environment varibles
ENV PYTHONUNBUFFERED 1

# Set work directory
RUN mkdir /code
WORKDIR /code

# Install dependencies
RUN pip install --upgrade pip
RUN pip install pipenv
COPY ./Pipfile /code/Pipfile
RUN pipenv install --deploy --system --skip-lock --dev

# Copy project
COPY . /code/

我的docker-compose:

My docker-compose:

version: '3'

services:
  db:
    image: postgres
    ports:
      - "5432:5432"
  web:
    build: .
    command: python3 manage.py collectstatic --noinput
    command: python3 manage.py migrate --noinput
    command: python3 manage.py runserver 0.0.0.0:8000
    env_file: .env
    volumes:
      - .:/code
    ports:
      - "8000:8000"
    depends_on:
      - db

entrypoint.sh

entrypoint.sh

#!/bin/bash

# Collect static files
echo "Collect static files"
python manage.py collectstatic --noinput

# Apply database migrations
echo "Apply database migrations"
python manage.py migrate

# Start server
echo "Starting server"
python manage.py runserver 0.0.0.0:8000

推荐答案

这是因为您只能有一个 command .

That is because you can only have one command.

您可以像这样组合多个命令:

You can combine multiple commands like this:

command: sh -c "python3 manage.py collectstatic --noinput && python3 manage.py migrate --noinput && python3 manage.py runserver 0.0.0.0:8000"

或者，正如您提到的入口点一样，您可以在 Dockerfile 或在 docker-compose.yml 中.请确保删除命令，因为您将不再需要它们.

Alternatively as you mentioned the entrypoint, you can specify the entrypoint in the Dockerfile or in docker-compose.yml. Make sure to remove the commands as you won't need them anymore.

关于入口点与cmd与运行，这是一篇不错的文章: http://goinbigdata.com/docker-run-vs-cmd-vs-entrypoint/
