django在docker环境中断点调试

之前是本地Python环境安装Django项目直接运行和断点，现在尝试切换到vscode～

vscode插件

Dockerfile配置

用于创建docker镜像

项目根目录中创建Dockerfile文件

# syntax=docker/dockerfile:1
FROM python:3.10

#设置容器中环境变量
ENV RUN_ENV='develop'
WORKDIR /data

COPY requirements.txt .
RUN pip install -i https://pypi.douban.com/simple/ -r requirements.txt

# 方式2.安装依赖
# RUN pip install -i https://pypi.douban.com/simple/ django pytz pymysql mysqlclient requests numpy python-dateutil matplotlib pandas_datareader scipy sklearn

根目录中需要有requirements.txt

docker-compose配置

用于开启容器，挂载开发目录以及端口

项目根目录中创建docker-compose.debug.yml文件

version: '3.4'

services:
  pythonsamplevscodedjangotutorial:
    image: django-dev:1.1
    build:
      context: .
      dockerfile: ./Dockerfile
    volumes:
      - ./:/data
    # command: ["sh", "-c", "pip install -i https://pypi.douban.com/simple/ debugpy -t /tmp && python /tmp/debugpy --wait-for-client --listen 0.0.0.0:5678  /data/manage.py runserver 0.0.0.0:8000 --nothreading --noreload"]
    command: ["sh", "-c", "python /tmp/debugpy --listen 0.0.0.0:5678  /data/manage.py runserver 0.0.0.0:8000 --nothreading --noreload "]
    ports:
      - 8000:8000
      - 5678:5678

说明：

volumes表示 映射本地路径-->容器路径

5678为断点监听端口
8000为项目访问端口

配置debug

配置vscode DEBUG

项目根目录中编辑或创建.vscode/launch.json

{
  "configurations": [
    {
       "name": "Python: Remote Attach",
       "type": "python",
       "request": "attach",
       "port": 5678,
       "host": "localhost",
       "pathMappings": [
           {
               "localRoot": "${workspaceFolder}",
               "remoteRoot": "/data"
           }
       ]
   }
  ]
}

启动容器

$ docker-compose -f ./docker-compose.debug.yml up

添加断点后，浏览器访问127.0.0.1:8000即可调试
