我的docker-compose正在从另一个文件夹中获取文件，而不是从我运行该命令的位置
进入容器后，由于某种原因它从这个位置读取代码，我不知道如何以及从何处加载代码： /家/指
但是所需的（真实代码）内容正在这里上传：
的/ opt / LTG /
这是我的docker-compose文件内容，我认为问题在于VOLUMES参数。
当我尝试进入容器内部并查找html视图时，结果显示它与我之前使用过的另一个文件夹相关联。
我使用https://github.com/meanjs/mean meanjs来构建我的项目，所以我使用他们的docker文件，所以他们使用docker的方式。

Dockerfile。 （我认为这个问题在这里），但即使我将/ home / mean更改为/ opt / ltg，它似乎也无法正常工作。

1 个答案:
答案 0 :(得分：0)
我认为我们需要更多信息才能正确回答这个问题。所以我会假设一些事情。
-
opt/ltg目录指向docker-compose.yml所在的目录，而不是您运行docker-compose的目录。通常是同一个目录。尝试修改我的docker-compose.yml就像添加注释一样。转到带有docker exec的容器并检查docker-compose.yml的内容，添加的注释应该在那里。 -
我认为您的html文件也会转到
/opt/ltg/public，因为您也将其声明为卷。 Docker将在您的主机中创建另一个与当前目录不同的目录。使用docker inspect查看它们的位置。如果您运行docker-compose down -v，您应该删除这些文件。 -
除非您确实需要，否则不要重叠卷。我建议改用此docker-compose.yml：
