## Synopsis

- Add or Remove load balancer from the OpenStack load-balancer service(Octavia). Load balancer update is not supported for now.

## Requirements

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

- openstacksdk
- openstacksdk >= 0.12.0
- python >= 2.7

## Parameters

Parameter | Choices/Defaults | 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, os_user_domain_name or os_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.

auto_public_ip
boolean

Choices:
- no ←
- yes

Allocate a public IP address and associate with the VIP automatically.

availability_zone - |  | Ignored. Present for backwards compatibility
ca_cert string |  | A path to a CA Cert bundle that can be used as part of verifying SSL API requests. aliases: cacert
client_cert string |  | A path to a client certificate to use as part of the SSL transaction. aliases: cert
client_key string |  | A path to a client key to use as part of the SSL transaction. aliases: key

cloud
raw

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.

delete_public_ip
boolean

Choices:
- no ←
- yes

When `state=absent` and this option is true, any public IP address associated with the VIP will be deleted along with the load balancer.

interface
string

Choices:
- admin
- internal
- public ←

Endpoint URL type to fetch from the service catalog.
aliases: endpoint_type

validate_certs
boolean

Choices:
- no ←
- yes

Whether or not SSL API requests should be verified.
Before Ansible 2.3 this defaulted to `yes`.
aliases: verify

vip_address - |  | IP address of the load balancer virtual IP.
vip_network - |  | The name or id of the network for the virtual IP of the load balancer. One of vip_network, vip_subnet, or vip_port must be specified for creation.
vip_port - |  | The name or id of the load balancer virtual IP port. One of vip_network, vip_subnet, or vip_port must be specified for creation.
vip_subnet - |  | The name or id of the subnet for the virtual IP of the load balancer. One of vip_network, vip_subnet, or vip_port must be specified for creation.

wait
boolean

Choices:
- no
- yes ←

If the module should wait for the load balancer to be created or deleted.

## 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/
