Role Name

ansible-role-tripleo-overcloud

Requirements

Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.

Role Variables

A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.

overcloud_ipv6: enables IPv6 deployment on the overcloud
enable_cinder_backup: false/true - enables cinder-backup service.
deployed_server: false/true - enables support for nodepool deployed server deployment (default: false)
overcloud_cloud_name: Sets the FQDN for the overcloud's public VIP.
overcloud_cloud_name_internal: Sets the FQDN for the overcloud's VIP for the internal network.
overcloud_cloud_name_storage: Sets the FQDN for the overcloud's VIP for the storage network.
overcloud_cloud_name_storage_management: Sets the FQDN for the overcloud's VIP for the storage management network.
overcloud_cloud_name_ctlplane: Sets the FQDN for the overcloud's VIP for the ctlplane network.
overcloud_cloud_domain: Sets the domain for the nodes' internal hostnames.
enable_swap: Enables swap in the overcloud nodes.
swap_type: Defines the approach to adding swap that will be used, the available options are 'file' and 'partition'. Defaults to 'file'.
composable_services: false/true - whether to use customized list of services
overcloud_services: structure specifying services for roles. See the overcloud-deploy role's defaults.yaml file for an example.
composable_roles: false/true - whether to use custom roles_data.yaml
overcloud_roles: contents of custom roles_data.yaml (as a YAML structure, not a string). See roles_data.yaml in the tripleo-heat-templates repository for example contents.

Dependencies

A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: servers
  roles:
     - { role: username.rolename, x: 42 }
