ParameterDescription

AddVipsToEtcHosts

Set to true to append per network VIPs to /etc/hosts on each node. The default value is: True

CloudDomain

The DNS domain used for the hosts. This should match the dhcp_domain configured in the undercloud. The default value is: localdomain

CloudName

The DNS name of this cloud. The default value is: overcloud.localdomain

CloudNameCtlplane

The DNS name of this cloud’s control plane endpoint. The default value is: overcloud.ctlplane.localdomain

CloudNameInternal

The DNS name of this cloud’s internal API endpoint. The default value is: overcloud.internalapi.localdomain

CloudNameStorage

The DNS name of this cloud’s storage endpoint. E.g. ci-overcloud.storage.tripleo.org. The default value is: overcloud.storage.localdomain

CloudNameStorageManagement

The DNS name of this cloud’s storage management endpoint. The default value is: overcloud.storagemgmt.localdomain

ControlFixedIPs

Defines a fixed VIP for the Control Plane. Value uses the following format: [{ip_address:'1.2.3.4'}]

ControlPlaneSubnet

The name of the undercloud OpenStack Networking (neutron) control plane subnet. The default value is: ctlplane-subnet

ControlPlaneSubnetCidr

The subnet CIDR of the control plane network. The parameter is automatically resolved from the ctlplane subnet’s cidr attribute.

DeployIdentifier

Setting this to a unique value will re-run any deployment tasks that perform configuration on a Heat stack-update.

DeploymentServerBlacklist

List of server hostnames to blacklist from any triggered deployments.

EndpointMapOverride

Can be used to override the calcluated EndpointMap.

ExtraConfig

Additional hiera configuration to inject into the cluster.

ExtraHostFileEntries

List of extra hosts entries to be appended to /etc/hosts.

HypervisorNeutronPhysicalBridge

An Open vSwitch bridge to create on each hypervisor. This defaults to br-ex, which is the same as the control plane nodes. This ensures uniform configuration of the Open vSwitch agent. Typically should not need to be changed. The default value is: br-ex

HypervisorNeutronPublicInterface

What interface to add to the HypervisorNeutronPhysicalBridge. The default value is: nic1

InternalApiVirtualFixedIPs

Control the IP allocation for the InternalApiVirtualInterface port. Value uses the following format: [{ip_address:'1.2.3.4'}]

NeutronControlPlaneID

ID or name for Control Plane ctlplane network. The default value is: ctlplane

NeutronPublicInterface

The interface to attach to the external bridge. The default value is: nic1

NodeCreateBatchSize

Maximum batch size for creating nodes. It is recommended to not exceed a batch size of 32 nodes. The default value is: 30

PublicVirtualFixedIPs

Control the IP allocation for the PublicVirtualInterface port. Value uses the following format: [{ip_address:'1.2.3.4'}]

RabbitCookieSalt

Salt for the RabbitMQ cookie. Change to force the randomly generated RabbitMQ cookie to change. The default value is: unset

RedisVirtualFixedIPs

Control the IP allocation for the virtual IP used by Redis. Value uses the following format: [{ip_address:'1.2.3.4'}]

ServerMetadata

Extra properties or metadata passed to Nova for the created nodes in the overcloud. Accessible through the Nova metadata API.

StorageMgmtVirtualFixedIPs

Control the IP allocation for the StorageMgmgVirtualInterface port. Value uses the following format: [{ip_address:'1.2.3.4'}]

StorageVirtualFixedIPs

Control the IP allocation for the StorageVirtualInterface port. Value uses the following format: [{ip_address:'1.2.3.4'}]

UpdateIdentifier

Set to a previously unused value during stack-update triggers package update on all nodes.
