Warning: Depending on your application, disabling the SELinux security layer might be a bad idea since it might introduce new security risks especially if the container system has security issues.
In order to disable SELinux on Fedora CoreOS, run this:
sudo sed -i -e 's/SELINUX=/SELINUX=disabled #/g' /etc/selinux/config sudo systemctl reboot
Note that this will reboot your system in order for the changes to take effect.
The sed command will replace the default
SELINUX=enforcing
in /etc/selinux/config to
SELINUX=disabled
