7. Customizing undercloud.confΒΆ

The undercloud.conf file is copied to the undercloud VM using a template where the system values are variables. <https://github.com/openstack/tripleo-quickstart/blob/master/roles/tripleo/undercloud/templates/undercloud.conf.j2>. The tripleo-quickstart defaults for these variables are suited to a virtual overcloud, but can be overwritten by passing custom settings to tripleo-quickstart in a settings file (–extra-vars @<file_path>). For example:

undercloud_network_cidr: 10.0.5.0/24
undercloud_local_ip: 10.0.5.1/24
undercloud_network_gateway: 10.0.5.1
undercloud_undercloud_public_vip: 10.0.5.2
undercloud_undercloud_admin_vip: 10.0.5.3
undercloud_local_interface: eth1
undercloud_masquerade_network: 10.0.5.0/24
undercloud_dhcp_start: 10.0.5.5
undercloud_dhcp_end: 10.0.5.24
undercloud_inspection_iprange: 10.0.5.100,10.0.5.120
