Functions

func List 

func List(c *gophercloud.ServiceClient, opts ListOptsBuilder) pagination.Pager

List returns a Pager which allows you to iterate over a collection of pools. It accepts a ListOpts struct, which allows you to filter and sort the returned collection for greater efficiency.

Default policy settings return only those pools that are owned by the tenant who submits the request, unless an admin user submits the request.

func ListAssociateMembers 

func ListAssociateMembers(c *gophercloud.ServiceClient, poolID string, opts MemberListOptsBuilder) pagination.Pager

List returns a Pager which allows you to iterate over a collection of members. It accepts a ListOpts struct, which allows you to filter and sort the returned collection for greater efficiency.

Default policy settings return only those members that are owned by the tenant who submits the request, unless an admin user submits the request.

Types

SOURCE_IP: With this mode, all connections originating from the same source 

IP address, will be handled by the same Member of the Pool.

create a cookie on the first request from a client. Subsequent
requests containing the same cookie value will be handled by
the same Member of the Pool.

rely on a cookie established by the backend application. All
requests carrying the same cookie value will be handled by the
same Member of the Pool.
