我的笔记本电脑上部署了一个openstack。我试图用热量创建一个堆栈。

我创建了一个密钥对openstack keypair create heat_key > heat_key.priv 由nova nova keypair-list识别的内容给出以下输出：

+----------+------+-------------------------------------------------+
| Name     | Type | Fingerprint                                     |
+----------+------+-------------------------------------------------+
| heat_key | ssh  | 0b:7a:36:20:e2:e3:19:3b:ab:a1:95:ac:67:41:67:d7 |
+----------+------+-------------------------------------------------+

这是我简单的HOT模板：

heat_template_version: 2013-05-23

description: Hot Template to deploy a single server

parameters:
  image_id:
    type: string
    description: Image ID
  key_name:
    type: string
    description: name of keypair to enable ssh to the instance

resources:
  test_stack:
    type: OS::Nova::Server
    properties:
      name: "test_stack"
      image: { get_param: image_id }
      flavor: "ds1G"
      key_name:{ get_param: key_name }

outputs:
  test_stack_ip:
    description: IP of the server
    value: { get_attr: [ test_stack, first_address ] }

当我尝试创建堆栈时

openstack stack create -t myTemp.hot --parameter key_name=heat_key --parameter image_id=trusty-server-cloudimg-amd64-disk1 test_stack

我收到以下错误

ERROR: Property error: : resources.test_stack.properties: : Unknown Property key_name:{ get_param

我尝试过不同版本的模板，但我得到了同样的错误

知道为什么会这样吗？

尝试将参数名称key_name更改为其他名称并执行

heat_template_version: 2015-10-15

description: Hot Template to deploy a single server

parameters:
  image_id:
    type: string
    description: Image ID
  key_pair_name:
    type: string
    description: name of keypair to enable ssh to the instance

resources:
  test_stack:
    type: OS::Nova::Server
    properties:
      name: "test_stack"
      image: { get_param: image_id }
      flavor: "ds1G"
      key_name: { get_param: key_pair_name }

outputs:
  test_stack_ip:
    description: IP of the server
    value: { get_attr: [ test_stack, first_address ] }

Answer 2

关于YAML文件的最糟糕的部分是，它是SPACE敏感的，所以在编辑或复制HEAT模板的内容时我们需要非常小心。 “key_name”和“{”之间没有空格，这就是它失败的原因。

key_name：{get_param：key_pair_name}

只需将an extra space放在这些之间即可。我测试了它:-)

key_name：{get_param：key_pair_name}

Answer 3

我能够通过提供参数中的细节来实现。 PFB示例脚本对我有用。

resources:

      key_name: { get_param: KeyName }
      networks:
        - network: { get_param : network_id_E1 }

openstack heat不识别key_name参数
