The neutron global_physnet_mtu must be set to the configured local_mtu in order to set local_mtu to a value greater than 1500. Otherwise the neutron configuration will fail during the undercloud install. Change-Id: Iaadff350a14a2cfb4bf545065f6d12eab49ba125 Closes-Bug: #1774271
puppet-stack-config
puppet-stack-config provides static puppet configuration for a single node baremetal cloud using the Ironic driver. A yaml template is used to render a hiera data file at /etc/puppet/hieradata/puppet-stack-config.yaml.
The template rendering takes its input from a set of defined environment variables.
