Roles
|
|
=====
|
|
|
|
The yaml files in this directory can be combined into a single roles_data.yaml
|
|
and be used with TripleO to create custom deployments.
|
|
|
|
Use tripleoclient to build your own custom roles_data.yaml for your
|
|
environment.
|
|
|
|
roles_data.yaml
|
|
---------------
|
|
|
|
The roles_data.yaml specifies which roles (groups of nodes) will be deployed.
|
|
Note this file is used as an input the the various \*.j2.yaml jinja2 templates,
|
|
so that they are converted into \*.yaml during the plan creation. This occurs
|
|
via a mistral action/workflow. The file format of this file is a yaml list.
|
|
|
|
Role YAML files
|
|
===============
|
|
|
|
Each role yaml file should contain only a single role. The filename should
|
|
match the role name. The name of the role is mandatory and must be unique.
|
|
|
|
The role files in this folder should contain at least a role name and the
|
|
default list of services for the role.
|
|
|
|
Role Options
|
|
------------
|
|
|
|
* CountDefault: (number) optional, default number of nodes, defaults to 0
|
|
sets the default for the {{role.name}}Count parameter in overcloud.yaml
|
|
|
|
* HostnameFormatDefault: (string) optional default format string for hostname
|
|
defaults to '%stackname%-{{role.name.lower()}}-%index%'
|
|
sets the default for {{role.name}}HostnameFormat parameter in overcloud.yaml
|
|
|
|
* disable_constraints: (boolean) optional, whether to disable Nova and Glance
|
|
constraints for each role specified in the templates.
|
|
|
|
* disable_upgrade_deployment: (boolean) optional, whether to run the
|
|
ansible upgrade steps for all services that are deployed on the role. If set
|
|
to True, the operator will drive the upgrade for this role's nodes.
|
|
|
|
* upgrade_batch_size: (number): batch size for upgrades where tasks are
|
|
specified by services to run in batches vs all nodes at once.
|
|
This defaults to 1, but larger batches may be specified here.
|
|
|
|
* ServicesDefault: (list) optional default list of services to be deployed
|
|
on the role, defaults to an empty list. Sets the default for the
|
|
{{role.name}}Services parameter in overcloud.yaml
|
|
|
|
* tags: (list) list of tags used by other parts of the deployment process to
|
|
find the role for a specific type of functionality. Currently a role
|
|
with both 'primary' and 'controller' is used as the primary role for the
|
|
deployment process. If no roles have have 'primary' and 'controller', the
|
|
first role in this file is used as the primary role.
|
|
|
|
* description: (string) as few sentences describing the role and information
|
|
pertaining to the usage of the role.
|
|
|
|
* networks: (list), optional list of networks which the role will have
|
|
access to when network isolation is enabled. The names should match
|
|
those defined in network_data.yaml.
|
|
|
|
Working with Roles
|
|
==================
|
|
The tripleoclient provides a series of commands that can be used to view
|
|
roles and generate a roles_data.yaml file for deployment.
|
|
|
|

Generate roles_data.yaml
|
|
------------------------
|
|
The ``openstack overcloud roles generate`` command can be used to generate
|
|
a roles_data.yaml file for deployments.
|
|
|
|
Usage
|
|
^^^^^
|
|
.. code-block::
|
|
|

|
Generate roles_data.yaml file
|
|
|
|
positional arguments:
|
|
<role> List of roles to use to generate the roles_data.yaml
|
|
file for the deployment. NOTE: Ordering is important
|
|
if no role has the "primary" and "controller" tags. If
|
|
no role is tagged then the first role listed will be
|
|
considered the primary role. This usually is the
|
|
controller role.

|
|
optional arguments:
|
|
-h, --help show this help message and exit
|
|
--roles-path <roles directory>

|
|
roles_data.yaml
