问题描述

    web:
        build:
            context: ./
            dockerfile: deploy/web.docker
        volumes:

推荐答案

在容器中从主机绑定挂载目录时，文件和目录保持它们在主机上的权限.这是设计使然:当使用绑定挂载时，您允许容器访问来自主机的现有文件，而 Docker 不会对这些文件进行修改；这样做会非常危险(例如，绑定挂载您的主目录会更改主机主目录的文件权限，可能导致您的机器不再可用).

When bind-mounting a directory from the host in a container, files and directories maintain the permissions they have on the host. This is by design: when using a bind-mount, you're giving the container access to existing files from the host, and Docker won't make modifications to those files; doing so would be very dangerous (for example, bind-mounting your home-directory would change file permissions of your host's home directory, possibly leading to your machine no longer being usable).

要更改这些文件的权限，请更改它们在主机上的权限.

To change permissions of those files, change their permissions on the host.
