Appendix B. Red Hat Hyper-converaged Infrastructure for Cloud undercloud configuration parameters
local_ip- The IP address defined for the director’s provisioning network. This is also the IP address the director uses for its DHCP and PXE boot services.
network_gateway- The gateway for the overcloud instances. This is the undercloud node, which forwards traffic to the external network.
undercloud_public_vip- The IP address defined for the director’s Public API. Use an IP address on the provisioning network that does not conflict with any other IP addresses or address ranges. The director configuration attaches this IP address to its software bridge as a routed IP address, which uses the /32 netmask.
undercloud_admin_vip- The IP address defined for the director’s Admin API. Use an IP address on the provisioning network that does not conflict with any other IP addresses or address ranges. The director configuration attaches this IP address to its software bridge as a routed IP address, which uses the /32 netmask.
local_interface-
The chosen interface for the director’s provisioning NIC. This is also the device the director uses for its DHCP and PXE boot services. The configuration script attaches this interface to a custom bridge defined with the
inspection_interfaceparameter. network_cidr- The network that the director uses to manage overcloud instances. This is the provisioning network, which the undercloud’s neutron service manages.
masquerade_network- Defines the network that will masquerade for external access. This provides the provisioning network with a degree of network address translation (NAT), so that it has external access through the director.
dhcp_start- The start of the DHCP allocation range for overcloud nodes. Ensure this range contains enough IP addresses to allocate to all nodes.
dhcp_end- The end of the DHCP allocation range for overcloud nodes. Ensure this range contains enough IP addresses to allocate to all nodes.
inspection_interface-
The bridge the director uses for node introspection. This is custom bridge that the director configuration creates. The
local_interfaceattaches to this bridge. Leave this as the default,br-ctlplane. inspection_iprange-
A range of IP address that the director’s introspection service uses during the PXE boot and provisioning process. Use comma-separated values to define the start and end of this range. Verify this range contains enough IP addresses for the nodes and does not conflict with the range for
dhcp_startanddhcp_end. inspection_extras-
Defines whether to enable extra hardware collection during the inspection process. Requires
python-hardwareorpython-hardware-detectpackage on the introspection image. inspection_runbench-
Runs a set of benchmarks during node introspection. Set to
trueto enable. This option is necessary if you intend to perform benchmark analysis when inspecting the hardware of registered nodes. inspection_enable_uefi- Defines whether to support introspection of nodes with UEFI-only firmware.
