Setup Docker host

Install Docker Engine

The Docker host to run xCAT Docker image should be a baremental or virtual server with Docker v1.10 or above installed. For the details on system requirements and Docker installation, refer to Docker Installation Docs.

Note:

1. Docker image can only run on 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
