Allow undercloud installations/upgrades from custom t-h-t, similarly to overcloud_templates_* et al. Unify and share custom t-h-t install script for OC and UC and mixed update/upgrade cases via new shared role tht-prep-config. To diverge undercloud from overcloud install/update/upgrade cases, use the following shared mappings (vars on the right correspond to UC cases): * tht_templates_path: undercloud_templates_path (defaults to RPM dir) * tht_templates_repo: undercloud_templates_repo * tht_templates_branch: undercloud_templates_branch * tht_templates_refspec: undercloud_templates_refspec and a 2nd group (defaults set to do nothing, but only disable the t-h-t prepare script's code blocks under control of those): * composable_scenario: undercloud_composable_scenario * upgrade_composable_scenario: undercloud_upgrade_composable_scenario * prep_post_hook_script: undercloud_prep_post_hook_script * download_templates_rpm: download_undercloud_templates_rpm * tht_rpm_url: undercloud_tht_rpm_url Those in group 2 may be customized to mimic the overcloud mixed upgrades logic for underclouds/all-in-one for future use. And for overclouds respectively, use mappings: * composable_scenario: remains unchanged * upgrade_composable_scenario: remains unchanged * prep_post_hook_script: overcloud_prep_post_hook_script * download_templates_rpm: download_overcloud_templates_rpm * tht_rpm_url: remains unchanged * tht_templates_path: overcloud_templates_path ...

ansible-role-tripleo-overcloud-prep-config
An Ansible role to copy configuration files to the undercloud prior to overcloud deployment.
Requirements
This playbook expects that the undercloud has been installed and setup using one of the roles relevant to baremetal overcloud deployments.
Role Variables
Note: Make sure to include all environment file and options from your initial Overcloud creation.
working_dir
: <'/home/{{ undercloud_user }}'> -- defined in roles/extras-commonbaremetal_instackenv
: <"{{ working_dir }}/instackenv.json"> -- location of instackenv.json to copy overbaremetal_network_environment
: <"{{ working_dir }}/network-isolation.yml"> -- location of network-environment file to copy overundercloud_type
: -- can be overwritten with values like 'baremetal' or 'ovb'extra_tht_configs
: -- a list of files to copy to the overcloud and add as extra config to the overcloud-deployment commandnetwork_isolation_type
: single-nic-vlans, multiple-nics, bond-with-vlans, public-bond - type of network isolation to use (default: single-nic-vlans) [1] deprecated types - single_nic_vlans, bond_with_vlans, multi-nicdownload_overcloud_templates_rpm
: if set to true, allow the user to download a tripleo-heat-templates rpm package from a url defined by the variabletht_rpm_url
overcloud_templates_path
: <'/usr/share/openstack-tripleo-heat-templates'> -- defined in roles/extras-commonovercloud_prep_post_hook_script
: if set to a non-empty string, it should be the content of a bash script that will be run at the end of the overcloud preparation configuration step. This should only be use in rare case.
[1] Names are derived from the tripleo-heat-templates configuration <https://github.com/openstack/tripleo-heat-templates/tree/master/network/config>

Role Network Variables
overcloud_dns_servers
: -- a list of nameservers to be used for the overcloud nodes. These will result in the 'DnsServers' parameter in heat, and will be added to thenetwork_environment_args
(see below). Defaults to [ '{{ external_network_cidr|nthhost(1) }}' ]
The following variables are nested under network_environment_args. The values are calculated at run time using ansible jinja filters. This are, in turn, persisted to a heat environment file that is used in for the overcloud deployment.
Note: See additional documentation at http://docs.ansible.com/ansible/playbooks_filters_ipaddr.html and the ansible code base ansible/plugins/filter/ipaddr.py
network_environment_args:
ExternalNetCidr: "{{ undercloud_external_network_cidr }}"
ExternalAllocationPools: >
[{'start': '{{ undercloud_external_network_cidr|nthhost(4) }}',
'end': '{{ undercloud_external_network_cidr|nthhost(250) }}'}]
NeutronExternalNetworkBridge: ""
ControlPlaneSubnetCidr: "{{ undercloud_network_cidr|ipaddr('prefix') }}"
ControlPlaneDefaultRoute: "{{ undercloud_network_cidr|nthhost(1) }}"
EC2MetadataIp: "{{ undercloud_network_cidr|nthhost(1) }}"
DnsServers: "{{ overcloud_dns_servers }}"
