Error starting day: SELinux is not supported with the overlay 2

Environment: centos7

Command: systemctl start docker

          systemctl status docker -l

Error starting day: SELinux is not supported with the overlay 2 graph driver on this kernel. Either boot into a new kernel or disable SELinux in docker (- – SELinux enabled = false)

Solution:

It means: SELinux in this Linux kernel does not support overlay 2 graph driver. There are two solutions: either start a new kernel or disable SELinux in docker, – SELinux enabled = false

To edit the docker profile again:

vi /etc/sysconfig/docker

Change to:

Then systemctl start docker is ready
