We Make Fedora
Description: Chenxiong Qi's personal site
I'm using Fedora 23 and also usually use docker to run a Fedora container so that I can have a ready-to-use environment quickly to run something, for example verifying a RPM by installing it simply. Volume is a much useful for sharing data between host and container, but without some magic, mounted volume inside container is not accessible, that is Permission Denied even if just ls .
This is related to the SELinux actually. I'm not a SELinux expert. I can't give any deeper explanation why this happens. All what I knew and learned is from this great article Using Volumes with Docker can Cause Problems with SELinux . The solution is to add suffix either z or Z . For example,
docker run --rm -i -t -v /path/to/host/dir:/path/to/container/dir:Z fedora:24 /bin/bash Volume Labels actually already describes the functionality of Z. But, it mentions nothing that is related to this issue and SELinux. I suspect, in Docker's documentation, Z is described in general for kinds of Linux distributions including those that don't use SELinux at all. Anyway, hopefully, this is useful for you to solve your problem. Happy hacking! :)
