使用 docker-compose 的 VScode 调试器

Question

最近我开始使用 docker 来运行我的项目，运行如下

• 姜戈
• nginx
• 鳐鱼
• 芹菜
• Postgres
• 雷迪斯

早些时候，设置调试器很容易，但使用 docker-compose 之后我无法做到这一点。一旦我启动调试器，它就会加载一段时间，然后自动停止，任何地方都没有日志或错误。这是相关代码。

启动.json

{
"configurations": [
    {
        "name": "Python: Remote Attach",
        "type": "python",
        "request": "attach",
        "connect": {
            "host": "localhost",
            "port": 443
        },
        "pathMappings": [
            {
                "localRoot": "${workspaceFolder}",
                "remoteRoot": "."
            }
        ]
    }
]
}

docker-compose.yml

最后我自己解决了。从这个问题中得出的结论很少。

您需要使用 debugpy 并将其放入manage.py文件中以开始侦听端口。我做了这样的事情

import debugpy

debugpy.listen(('0.0.0.0', 5678))
debugpy.wait_for_client()
debugpy.breakpoint()

除此之外，我们还需要将此端口映射到主机内的端口。为此，我们需要在docker-compose 的Web服务中更改并添加一行

ports:
    - "5678:5678"

我的 launch.json 看起来像这样

{
"configurations": [
    {
        "name": "Python: Remote Attach",
        "type": "python",
        "request": "attach",
        "connect": {
            "host": "0.0.0.0",
            "port": 5678
        },
        "pathMappings": [
            {
                "localRoot": "${workspaceFolder}/myapp",
                "remoteRoot": "."
            }
        ]
    }
]
}

注意：确保您的需求文件中有 debugpy 或手动安装它。
