The UPI Ansible playbooks create machine network and subnet without setting an external DNS resolver. 'inventory.yaml' does not give the option of setting an external DNS resolver, whereas IPI's install-config.yaml does. Version: UPI 4.12 Platform: OpenStack
Verified with OCP 4.12.0-0.nightly-2022-09-14-101116 on top of RHOS-16.2-RHEL-8-20220804.n.1. Verification steps: - Using the default DNS values (Invalid DNS for the environment), and the UPI installation failed. - Using the OpenStack defaults DNS (Removed the values under the os_external_dns section), and the UPI installation passed. - Updated the os_external_dns to a correct DNS server, and the UPI installation passed.
