openstack.cloud.lb_pool module – Manage load-balancer pool in a OpenStack cloud.

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.lb_pool.

Synopsis

  • Add, update or remove load-balancer pool from OpenStack cloud.

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.

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.

description

string

A human-readable description for the load-balancer pool.

interface

aliases: endpoint_type

string

Endpoint URL type to fetch from the service catalog.

Choices:

  • "admin"

  • "internal"

  • "public" ← (default)

lb_algorithm

string

The load balancing algorithm for the pool.

For example, lb_algorithm could be LEAST_CONNECTIONS, ROUND_ROBIN, SOURCE_IP or SOURCE_IP_PORT.

Default: "ROUND_ROBIN"

listener

string

The name or id of the listener that this pool belongs to.

Either listener or loadbalancer must be specified for pool creation.

This attribute cannot be updated.

loadbalancer

string

The name or id of the load balancer that this pool belongs to.

Either listener or loadbalancer must be specified for pool creation.

This attribute cannot be updated.

name

string / required

Name that has to be given to the pool.

This attribute cannot be updated.

protocol

string

The protocol for the pool.

For example, protocol could be HTTP, HTTPS, PROXY, PROXYV2, SCTP, TCP and UDP.

This attribute cannot be updated.

Default: "HTTP"

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/
