OpenShift Node Configuration

Clone the template following the procedure described here Cloning a KVM Guest. While cloning, consider the following:

Adjust the memory and the number of virtual CPUs.

Configure the DNS client to use the DNS server that was installed as part of the procedure. See "manual /etc/resolv.conf Configuration" and https://docs.openshift.com/container-platform/3.5/install_config/install/prerequisites.html#prereq-dns

Configure docker disk (note that the sequence described blow needs a modified /usr/bin/docker-storage-setup): 

systemctl stop docker
unalias rm
rm -r /var/lib/docker
cat /dev/null > /etc/sysconfig/docker-storage
pvs
fdisk /dev/vdb
/usr/bin/docker-storage-setup --force
systemctl is-enabled docker
systemctl start docker
systemctl status docker
