  {
    "Action":"Configure",
    "PlaybookName": "<VNFCode>/<Version>/ansible/configure/site.yml",
    "NodeList": [
      {
        "vnfc_type": "oam",
        "ne_id_vip": "vfdb9904vm001oam001",
        "floating_ip_address_vip": "1xx.2yy.zzz.109",
        "site": "wp0ny",
        "vm_info": [
          {
            "ne_id": "vfdb9904vm001oam001",
            "fixed_ip_address": "1xx.2yy.zzz.109"
          },
          {
            "ne_id": "vfdb9904vm002oam001",
            "fixed_ip_address": "1xx.2yy.zzz.110"
          }
        ]
      },
      {
        "vnfc_type": "rdb",
        "site": "wp0ny",
        "vm_info": [
          {
            "ne_id": "vfdb9904vm003rdb001",
            "fixed_ip_address": "1xx.2yy.zzz.105"
          },
          {
            "ne_id": "vfdb9904vm004rdb001",
            "fixed_ip_address": "1xx.2yy.zzz.106"
          }
        ]
      }
    ],
    "Timeout": 60,
    "InventoryNames": "None",
    "EnvParameters": {"vnf_instance": "$vnf-instance", "Retry": 3, "Wait": 5, "ConfigFile":"config.txt", "healthcheck_type": "$healthcheck_type",  "target_vm_list": ["$ne-id1","..."] },
    "FileParameters": {"config.txt":"db_ip=10.1.1.1, sip_timer=10000"}
  }

In the above example, the Ansible Server Rest API code will:

#. Process the "FileParameters" dictionary and generate a file named
   'config.txt' with contents set to the value of the 'config.txt' key.

#. Execute the playbook named '<VNFCode>/<Version>/ansible/configure/site.yml'
   on nodes with listed IP addresses (or FQDNs) respectively while providing
   the following key value pairs to the playbook: Retry=3, Wait=5,
   ConfigFile=config.txt

#. If execution time of the playbook exceeds 60 secs (across all hosts),
   it will be terminated.

#. Inventory hosts file to be build with only IP addresses (or FQDNs), IP
   addresses and VM names, or IP addresses and VNFC names depending on
   InventoryNames setting in the template(s) passed to Ansible Server as part
   of the Rest API request. In a later section with Ansible examples, examples
   of supported inventory hosts file formats are shared.
