// WARNING: This file is automatically generated from OpenAPI schema using
// `openstack-codegenerator`.

//! This operation provisions a member and adds it to a pool by using the
//! configuration that you define in the request object. After the API
//! validates the request and starts the provisioning process, it returns a
//! response object, which contains a unique ID.
//!
//! In the response, the member [provisioning status](#prov-status) is
//! `ACTIVE`, `PENDING_CREATE`, or `ERROR`.
//!
//! If the status is `PENDING_CREATE`, issue GET
//! `/v2/lbaas/pools/{pool_id}/members/{member_id}` to view the progress of the
//! provisioning operation. When the member status changes to `ACTIVE`, the
//! member is successfully provisioned and is ready for further configuration.
//!
//! If the API cannot fulfill the request due to insufficient data or data that
//! is not valid, the service returns the HTTP `Bad Request (400)` response
//! code with information about the failure in the response body. Validation
//! errors require that you correct the error and submit the request again.
//!
//! At a minimum, you must specify these member attributes:
//!
//! Some attributes receive default values if you omit them from the request:
//!
//! If you omit the `subnet_id` parameter, the `vip_subnet_id` for the parent
//! load balancer will be used for the member subnet UUID.
//!
//! The member `address` does not necessarily need to be a member of the
//! `subnet_id` subnet. Members can be routable from the subnet specified
//! either via the default route or by using `host_routes` defined on the
//! subnet.
//!
//! Administrative users can specify a project ID that is different than their
//! own to create members for other projects.
//!
//! `monitor_address` and/or `monitor_port` can be used to have the health
//! monitor, if one is configured for the pool, connect to an alternate IP
//! address and port when executing a health check on the member.
//!
//! To create a member, the load balancer must have an `ACTIVE` provisioning
//! status.
