Run the inventory script on its own to generate a list of environments, VMs and VM login credentials:

ansible -i cloudshare-inv.py all -m ping

The output is a JSON document that looks like this:

{ 
 "docker-templates": {
 "hosts": [ 
 "ubuntu-14-04-server-64-bit-small", 
 "ubuntu-14-04-server-64-bit-medium", 
 "ubuntu-14-04-server-64-bit-large", 
 "ubuntu-16-04-lts-server-small", 
 "ubuntu-16-04-lts-server-medium", 
 "ubuntu-16-04-lts-server-large" 
 ] 
}, 
"_meta": { 
 "hostvars": { 
 "login credentials": "will be populated here..." 
 } 
 } 
} 

Here we have one environment called docker-templates with six VMs.
