os_pool – Add/Delete a pool in the load balancing service from OpenStack Cloud

New in version 2.7.

Synopsis

  • Add or Remove a pool from the OpenStack load-balancer service.

Requirements

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

  • openstacksdk
  • python >= 2.7

Parameters

Parameter Choices/Defaults Comments
api_timeout
-
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 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 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
-
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
-
Ignored. Present for backwards compatibility
cacert
-
A path to a CA Cert bundle that can be used as part of verifying SSL API requests.
cert
-
A path to a client certificate to use as part of the SSL transaction.
cloud
-
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.
interface
-
added in 2.3
    Choices:
  • public ←
  • internal
  • admin
Endpoint URL type to fetch from the service catalog.

aliases: endpoint_type
key
-
A path to a client key to use as part of the SSL transaction.
lb_algorithm
-
    Choices:
  • LEAST_CONNECTIONS
  • ROUND_ROBIN ←
  • SOURCE_IP
The load balancing algorithm for the pool.
listener
-
The name or id of the listener that this pool belongs to. Either loadbalancer or listener must be specified for pool creation.
loadbalancer
-
The name or id of the load balancer that this pool belongs to. Either loadbalancer or listener must be specified for pool creation.
name
- / required
Name that has to be given to the pool
protocol
-
    Choices:
  • HTTP ←
  • HTTPS
  • PROXY
  • TCP
  • UDP
The protocol for the pool.
region_name
-
Name of the region.
state
-
    Choices:
  • present ←
  • absent
Should the resource be present or absent.
timeout
-
Default:
180
The amount of time the module should wait for the pool to get into ACTIVE state.
verify
boolean
    Choices:
  • no
  • yes
Whether or not SSL API requests should be verified. Before 2.3 this defaulted to True.

aliases: validate_certs
wait
boolean
    Choices:
  • no
  • yes ←
If the module should wait for the pool to be ACTIVE.

Notes

Note

  • The standard OpenStack environment variables, such as OS_USERNAME may be used instead of providing explicit values.
  • Auth information is driven by os-client-config, 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 http://docs.openstack.org/developer/os-client-config

Examples

# Create a pool, wait for the pool to be active.
- os_pool:
    cloud: mycloud
    endpoint_type: admin
    state: present
    name: test-pool
    loadbalancer: test-loadbalancer
    protocol: HTTP
    lb_algorithm: ROUND_ROBIN

# Delete a pool
- os_pool:
    cloud: mycloud
    endpoint_type: admin
    state: absent
    name: test-pool
