Clone the Basic Template
Use the basic template as a base image, and clone it, as described here:
The particular sequence follows:
virsh shutdown ocp36.basic-template
virsh dumpxml ocp36.basic-template > /root/environments/ocp36/ocp36.basic-template.xml cp ocp36.basic-template.xml ocp36.generic-template.xml
Adjust the configuration as described here.
Clone the virtual machine image and create the new disk volumes, as described in Cloning a Guest.
virsh define /root/environments/ocp36/ocp36.generic-template.xml
virsh start --console ocp36.generic-template
Then reconfigure Linux VM Guest Image.
Install OpenShift Binaries
Subscription
Attach the node to the subscription, using subscription manager, as described here: registering a RHEL System with subscription manager. The support node(s) need only a Red Hat Enterprise Linux. The OpenShift nodes need an OpenShift subscription. For OpenShift, follow these steps: https://docs.openshift.com/container-platform/3.5/install_config/install/host_preparation.html#host-registration.
The the summary of the sequence of steps is available below - the goal of these steps is to configure the following supported repositories on the system: "rhel-7-server-rpms", "rhel-7-server-extras-rpms", "rhel-7-server-ose-3.5-rpms", "rhel-7-fast-datapath-rpms":
subscription-manager register subscription-manager list --available --matches '*OpenShift*' subscription-manager attach --pool=<pool-id> --quantity=1 subscription-manager repos --disable="*" subscription-manager repos --list-enabled yum repolist yum-config-manager --disable <repo_id> subscription-manager repos --enable="rhel-7-server-rpms" --enable="rhel-7-server-extras-rpms" --enable="rhel-7-server-ose-3.5-rpms" --enable="rhel-7-fast-datapath-rpms" subscription-manager repos --list-enabled yum repolist
- Install base packages (https://docs.openshift.com/container-platform/3.5/install_config/install/host_preparation.html#installing-base-packages):
yum update -y yum install atomic-openshift-utils
