Internal
Clone the Generic Template
Use the generic template as a base image and clone it, as described below.
While cloning the guest, make sure to:
- Adjust the memory and the number of virtual CPUs.
- Provision docker storage sized proportionally with the nature of the node.
The process will produce a ocp36.master (smaller docker storage), ocp36.infanode, ocp36.node1, ocp36.node2, etc.
Resources
Verify resources (memory, CPU).
OpenShift Node Configuration
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
