为什么模块 os_keypair 没有返回 private_key？

我正在使用 OpenStack ansible 模块部署到 Rackspace Cloud。

我在创建 SSH 密钥对时遇到问题。它会创建公钥并将其安装在主机上。但是我看到返回的 JSON 不包含 private_key 键值对。

- name: SSH key check
  os_keypair:
    auth:
      auth_url: "{{ os_auth_url }}"
      project_name: "{{ os_project_name }}"
      username: "{{ os_username }}"
      password: "{{ os_password }}"
    state: present
    region_name: "{{ os_region }}"
    name: "{{ os_key_name }}"
  register: keypair

- name: Create local public
  local_action:
    module: copy
    content: "{{ keypair.key.public_key }}"
    dest: "~/.ssh/{{ keypair.key.name }}.pub"

- name: Create local private key
  local_action:
    module: copy
    content: "{{ keypair.key.private_key }}"
    dest: "~/.ssh/{{ keypair.key.name }}"
  ignore_errors: True

密钥对变量的值：

{
"changed": false,
"id": "openstack",
"key": {
  "public_key": "ssh-rsa AAAAByouknowwhatapublickeylookslikeyouknowwhatapublickeylookslikeyouknowwhatapublickeylookslikeyouknowwhatapublickeylookslikeyouknowwhatapublickeylookslikeyouknowwhatapublickeylookslikeyouknowwhatapublickeylookslikeyouknowwhatapublickeylookslikeyouknowwhatapublickeylookslikeyouknowwhatapublickeylookslikeyouknowwhatapublickeylookslikeyouknowwhatapublickeylookslikeJiln Generated-by-Nova",
  "NAME_ATTR": "name",
  "name": "openstack",
  "fingerprint": "89:e9:3d:s0:m3:nu:mb:3r:41:d5:09:8b:a9:b8:50:65",
  "id": "openstack",
  "human_id": null,
  "request_ids": [],
  "HUMAN_ID": false,
  "x_openstack_request_ids": []
  }
}

正如你所见，private_key不存在。根据文档它应该归还它。

对这一切来说都很新，所以要温柔一点:)

我相信该os_keypair模块没有对系统进行任何更改。变量的内容keypair表明：

{
  "changed": false,
  ...
}

ansible 文档对返回 a 是这样说的private_key。

仅当为用户生成密钥对时（例如，创建密钥对并且未指定公钥时）。

如果公钥存在，我认为模块不会生成新的密钥对。
