Issue
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 ?
Solution
Firstly, etc/hosts is a networking file present on all linux systems, it is not related to drives or docker.
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
for example:
docker run -v /path/on/host:/path/inside/container <image_name>
