Chapter 1. Core Overcloud Parameters

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 OpenStack Orchestration (heat) stack-update.

DeploymentServerBlacklist

List of server hostnames to blacklist from any triggered deployments.

EndpointMapOverride

Can be used to override the calcluated EndpointMap.

ExternalVirtualFixedIPs

Control the IP allocation for the ExternalVirtualInterface port. E.g. [{ip_address:'1.2.3.4'}].

ExtraConfig

Additional hiera configuration to inject into the cluster.

ExtraHostFileEntries

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

GlobalConfigExtraMapData

Map of extra global_config_settings data to set on each node.

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.

NovaAdditionalCell

Whether this is an cell additional to the default cell. The default value is False.

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 OpenStack Compute (nova) for the created nodes in the overcloud. Accessible through the OpenStack Compute (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.
