OpenShift 3.6 Node Guest Configuration
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.
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
