The first time I have succeeded to start a Docker container my reaction was: “Ouawwww, incredibly simple and fast!”. However, before having this feeling I have faced a failure while trying to start the docker daemon : “SELinux is not supported with the BTRFS graph driver!”.
This is a known issue for systems running a BTRFS filesystem. Hopefully a workaround exists. It consists in editing
/etc/sysconfig/docker to replace
Once the update made, you have to restart the daemon.
