问题描述
我在 Ubuntu 服务器主机上有一个 Docker Ubuntu 仿生容器.从容器中，我可以看到主机驱动器安装为/etc/hosts，它不是目录.尝试在不同的位置卸载和重新安装，但抛出 permission denied 错误，当我以 root 身份尝试时会发生这种情况.那么如何访问主机系统的内容?
I have a Docker Ubuntu bionic container on A Ubuntu server host. From the container I can see the host drive is mounted as /etc/hosts which is not a directory. Tried unmounting and remounting on a different location but throws permission denied error, this happens when I am trying as root.So How do you access the contents of your host system ?
推荐答案
首先，etc/hosts 是一个存在于所有 linux 系统上的网络文件，它与驱动器或 docker 无关.
Firstly, etc/hosts is a networking file present on all linux systems, it is not related to drives or docker.
其次，如果您想访问 Docker 容器内的部分主机文件系统，您需要使用 volumes.在 docker run 命令中使用 -v 标志，您可以指定主机上的目录以安装到容器中，格式为:
Secondly, if you want to access part of the host filesystem inside a Docker container you need to use volumes. Using the -v flag in a docker run command you can specify a directory on the host to mount into the container, in the format:
-v /path/on/host:/path/inside/container
例如:
docker run -v /path/on/host:/path/inside/container <image_name>
