openstack.cloud.host_aggregate module – Manage OpenStack host aggregates

Note

This module is part of the openstack.cloud collection (version 2.3.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install openstack.cloud. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: openstack.cloud.host_aggregate.

Synopsis

• Create, update, or delete OpenStack host aggregates. If a aggregate with the supplied name already exists, it will be updated with the new name, new availability zone, new metadata and new list of hosts.

Requirements

The below requirements are needed on the host that executes this module.

• python >= 3.6

• openstacksdk >= 1.0.0

Parameters

Parameter	Comments
api_timeout integer	How long should the socket layer wait before timing out for API calls. If this is omitted, nothing will be passed to the requests library.
auth dictionary	Dictionary containing auth information as needed by the cloud’s auth plugin strategy. For the default password plugin, this would contain auth_url, username, password, project_name and any information about domains (for example, user_domain_name or project_domain_name) if the cloud supports them. For other plugins, this param will need to contain whatever parameters that auth plugin requires. This parameter is not needed if a named cloud is provided or OpenStack OS_* environment variables are present.
auth_type string	Name of the auth plugin to use. If the cloud uses something other than password authentication, the name of the plugin should be indicated here and the contents of the auth parameter should be updated accordingly.
availability_zone string	Availability zone to create aggregate into.
ca_cert aliases: cacert string	A path to a CA Cert bundle that can be used as part of verifying SSL API requests.
client_cert aliases: cert string	A path to a client certificate to use as part of the SSL transaction.
client_key aliases: key string	A path to a client key to use as part of the SSL transaction.
cloud any	Named cloud or cloud config to operate against. If cloud is a string, it references a named cloud config as defined in an OpenStack clouds.yaml file. Provides default values for auth and auth_type. This parameter is not needed if auth is provided or if OpenStack OS_* environment variables are present. If cloud is a dict, it contains a complete cloud configuration like would be in a section of clouds.yaml.
hosts list / elements=string	List of hosts to set for an aggregate.
interface aliases: endpoint_type string	Endpoint URL type to fetch from the service catalog. Choices: "admin" "internal" "public" ← (default)
metadata dictionary	Metadata dict.
name string / required	Name of the aggregate.
purge_hosts boolean	Whether hosts not in hosts should be removed from the aggregate Choices: false true ← (default)
region_name string	Name of the region.
sdk_log_level string	Log level of the OpenStackSDK Choices: "INFO" ← (default) "DEBUG"
sdk_log_path string	Path to the logfile of the OpenStackSDK. If empty no log is written
state string	Should the resource be present or absent. Choices: "present" ← (default) "absent"
timeout integer	How long should ansible wait for the requested resource. Default: 180
validate_certs aliases: verify boolean	Whether or not SSL API requests should be verified. Before Ansible 2.3 this defaulted to true. Choices: false true
wait boolean	Should ansible wait until the requested resource is complete. Choices: false true ← (default)

Notes

Note

• The standard OpenStack environment variables, such as OS_USERNAME may be used instead of providing explicit values.

• Auth information is driven by openstacksdk, which means that values can come from a yaml config file in /etc/ansible/openstack.yaml, /etc/openstack/clouds.yaml or ~/.config/openstack/clouds.yaml, then from standard environment variables, then finally by explicit parameters in plays. More information can be found at https://docs.openstack.org/openstacksdk/

Examples

# Create a host aggregate
- openstack.cloud.host_aggregate:
    cloud: mycloud
    state: present
    name: db_aggregate
    hosts:
      - host1
      - host2
    metadata:
      type: dbcluster

# Add an additional host to the aggregate
- openstack.cloud.host_aggregate:
    cloud: mycloud
    state: present
    name: db_aggregate
    hosts:
      - host3
    purge_hosts: false
    metadata:
      type: dbcluster

# Delete an aggregate
- openstack.cloud.host_aggregate:
    cloud: mycloud
    state: absent
    name: db_aggregate
