Adding a New Node
New nodes can be added with the scaleup.yml playbook. The playbook generates and distributes new certificates for the new hosts, then runs the configuration playbook on the new hosts only. However, before running the playbook, the host must be prepared in the same way the other nodes were. If the nodes were created based on a template, the same template should be used to stand up the new node. For more details, see:
Use the same Ansible inventory file that was used to install the rest of the cluster.
