如何使用和格式化动态库存 - Ansible

Question

尝试格式化有效的动态库存。这是怎么做到的？

这是一个脚本，它将获取 terraform 的状态文件并使其成为可用的库存。我需要知道 Ansible 中使用的动态清单的格式。
我尝试运行以下库存：ansible all -i test.json -m ping

{
    "_meta": {
        "hostvars": { }
    },

    "instances": {
        "hosts": ["10.66.70.33"]
    }
}

结果：

 [WARNING]:  * Failed to parse /etc/ansible/test.json with yaml plugin: Invalid "hosts" entry for "instances" group,
requires a dictionary, found "<type 'list'>" instead.

 [WARNING]:  * Failed to parse /etc/ansible/test.json with ini plugin: /etc/ansible/test.json:2: Expected
key=value host variable assignment, got: {

 [WARNING]: Unable to parse /etc/ansible/test.json as an inventory source

 [WARNING]: No inventory was parsed, only implicit localhost is available

{ | UNREACHABLE! => {
    "changed": false, 
    "msg": "Failed to connect to the host via ssh: ssh: Could not resolve hostname {: Temporary failure in name resolution", 
    "unreachable": true
}

找到一种有效的格式：

{
   "all": {
      "hosts": "10.66.70.33",
      "children": {
         "instances": {
            "hosts": {
               "10.66.70.33":
            }
         }
      }
   }
}
