关于chatGPT对有关Docker Desktop问题的一个回答

1、关于chatGPT

最近用https://github.com/Hitachi-Automotive-And-Industry-Lab/semantic-segmentation-editor的基于React的web端数据标记工具，挺好用。

但发现即便删除了container，之前标注的label都还在，觉得很奇怪，因为mongodb也一起删除了，数据应该没有才对

但看见docker-compose的配置文件里有这么一句在mongodb下，其中data应该是本地路径，data/db是container内部路径，一个映射罢了

volumes:
      - data:/data/db

查了很久，包括stack overflow，官网，但还是半明白，因为我找不到这个data在本地什么位置

好不容易查到这似乎是一种volume，docker volume ls可以查看到

local     fb3597f34e995983a81b99f4f6fcebb74a1fcd6d19c676a2af363bf608083985
local     fc588f7ad21e2e7eeb0ee0931bc2780e98589b45cc83ea6abdc46bce30df1084
local     labelling_data

可见果然有这么个volume叫labelling_data存储着我标记的数据，也可以删除，但还是找不到在本地什么位置

于是抱着侥幸问了下chatGPT，惊了

我问：
In desktop docker’s configure file, I found ‘data:/data/db’ in the volume field of mongodb, what does the data mean, where is this data in my local windows system

chatGPT答：

原来data并不是本地某一个文件夹，而是由docker管理的一个虚拟volume，不能直接访问

2、完整的docker-compose配置文件

使用前唯一要改的是app的volumes的本地路径，改成相应的图像所在文件夹路径即可
