**Note:** **Docker image** can only run on the **Docker host** with the same architecture. Since xCAT currently only ships x86_64 and ppc64le Docker images, running xCAT in Docker requires x86_64 or ppc64le **Docker hosts**.
Shutdown the SELinux/Apparmor on Docker host
--------------------------------------------
If the SELinux or Apparmor on Docker host is enabled, the services/applications inside Docker Container might be confined. To run xCAT in Docker container, SELinux and Apparmor on the Docker host must be disabled.
SELinux can be disabled with: ::
echo 0 > /selinux/enforce
sed -i 's/^SELINUX=.*$/SELINUX=disabled/' /etc/selinux/config
AppArmor can be disabled with: ::
/etc/init.d/apparmor teardown
