Unable to associate public IP with loadbalancer

[heytrav]

Description

I am unable to associate a public IP address with a loadbalancer using the Ansible os_loadbalancer module. I'm following the example code using the auto_public_ip option to try to tell Ansible to create the loadbalancer with a public IP.

     - name: Create loadbalancer                                                                                                                        
       register: loadbalancer_result                                                                                                                    
       os_loadbalancer:                                                                                                                                 
         cloud: "ansible-training"                                                                                                                      
         name: "my-lb"                                                                                                                
         interface: public                                                                                                                              
         auto_public_ip: true                                                                                                                           
         state: present                                                                                                                                 
         vip_network: "training-public"                                                                                                              
         wait: yes                                                                                                                                      
         timeout: 300                                                                                                                                   
                         

It also does not seem to be possible to associate a floating IP with a loadbalancer using os_floating_ip and assigning it to the loadbalancer.

Expected Result:

Loadbalancer is created with a floating IP

Actual Result:

TASK [Create loadbalancer] ******************************************************************************************************************************
fatal: [localhost]: FAILED! => {"changed": false, "msg": "Unsupported parameters for (os_loadbalancer) module: auto_public_ip Supported parameters include: api_timeout, auth, auth_type, availability_zone, cacert, cert, cloud, interface, key, name, region_name, state, timeout, verify, vip_address, vip_network, vip_port, vip_subnet, wait"}

I'm currently using Ansible 2.7.6:
