Adding compute machines to a cluster on oVirt

Modify the inventory.yml file to include the new workers.

Run the create-templates-and-vms Ansible playbook to create the disks and virtual machines:

$ ansible-playbook -i inventory.yml create-templates-and-vms.yml

Run the workers.yml Ansible playbook to start the virtual machines:

$ ansible-playbook -i inventory.yml workers.yml

CSRs for new workers joining the cluster must be approved by the administrator. The following command helps to approve all pending requests:

$ oc get csr -ojson | jq -r '.items[] | select(.status == {} ) | .metadata.name' | xargs oc adm certificate approve
