Docker container receives permission denied in mounts

On RHEL, CentOS, Fedora, and other SELinux-enabled distributions, creating a docker image with mounts and turned-on SELinux returns permission denied:

docker run --rm -it -v $(pwd):/home centos7
[root@4b348767653c ~]# ls /home
ls: cannot open directory /home: Permission denied

How do I continue using Docker images with mounted volumes without turning off SELinux?

Solution

  • Use special flag :Z to mount your volumes, for example:

    docker run --rm -it -v $(pwd):/home:Z centos7
[root@4b348767653c ~]# ls /home
