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-common
• baremetal_instackenv: <"{{ working_dir }}/instackenv.json"> -- location of instackenv.json to copy over
• baremetal_network_environment: <"{{ working_dir }}/network-isolation.yml"> -- location of network-environment file to copy over
• undercloud_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 command
• network_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-nic
• download_overcloud_templates_rpm: if set to true, allow the user to download a tripleo-heat-templates rpm package from a url defined by the variable tht_rpm_url
• overcloud_templates_path: <'/usr/share/openstack-tripleo-heat-templates'> -- defined in roles/extras-common
• overcloud_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 the network_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 }}"
