+. 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

+. CSRs for new workers joining the cluster must be approved by the administrator.
