Recently I installed Docker CE on my Oracle Linux. Unfortunately, when I want to start my first container with:
docker run hello-world
Per the bug that david-maze linked to, updating container-selinux should fix this for you:
container-selinux
sudo yum install http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.107-1.el7_6.noarch.rpm
