编排¶

创建一个模板¶

Orchestration服务使用模版来描述栈。想要学习模版语言，参考`Heat developer documentation <http://docs.openstack.org/developer/heat/template_guide/index.html>`__中的`the Template Guide <http://docs.openstack.org/developer/heat/index.html>`__ 。

使用下面的内容创建``demo-template.yml``文件：

heat_template_version: 2015-10-15
description: Launch a basic instance with CirrOS image using the
             ``m1.tiny`` flavor, ``mykey`` key,  and one network.

parameters:
  NetID:
    type: string
    description: Network ID to use for the instance.

resources:
  server:
    type: OS::Nova::Server
    properties:
      image: cirros
      flavor: m1.tiny
      key_name: mykey
      networks:
      - network: { get_param: NetID }

outputs:
  instance_name:
    description: Name of the instance.
    value: { get_attr: [ server, name ] }
  instance_ip:
    description: IP address of the instance.
    value: { get_attr: [ server, first_address ] }

创建一个stack¶

使用``demo-template.yml`` 模版创建一个栈。

加载 ``demo``证书，作为非管理员项目执行下面的步骤：
```
$ . demo-openrc
```

检测可用网络。

$ openstack network list
+--------------------------------------+-------------+--------------------------------------+
| ID                                   | Name        | Subnets                              |
+--------------------------------------+-------------+--------------------------------------+
| 4716ddfe-6e60-40e7-b2a8-42e57bf3c31c | selfservice | 2112d5eb-f9d6-45fd-906e-7cabd38b7c7c |
| b5b6993c-ddf9-40e7-91d0-86806a42edb8 | provider    | 310911f6-acf0-4a47-824e-3032916582ff |
+--------------------------------------+-------------+--------------------------------------+

注解

这个输出可能跟你的环境有所不同。

设置”NET_ID”环境变量表示网络ID。例如，使用提供者网络：

$ export NET_ID=$(openstack network list | awk '/ provider / { print $2 }')

在提供者网络上创建一个CirrOS实例的栈：

$ openstack stack create -t demo-template.yml --parameter "NetID=$NET_ID" stack
+--------------------------------------+------------+--------------------+---------------------+--------------+
| ID                                   | Stack Name | Stack Status       | Creation Time       | Updated Time |
+--------------------------------------+------------+--------------------+---------------------+--------------+
| dbf46d1b-0b97-4d45-a0b3-9662a1eb6cf3 | stack      | CREATE_IN_PROGRESS | 2015-10-13T15:27:20 | None         |
+--------------------------------------+------------+--------------------+---------------------+--------------+

等一小段时间，验证stack的创建是否成功：

$ openstack stack list
+--------------------------------------+------------+-----------------+---------------------+--------------+
| ID                                   | Stack Name | Stack Status    | Creation Time       | Updated Time |
+--------------------------------------+------------+-----------------+---------------------+--------------+
| dbf46d1b-0b97-4d45-a0b3-9662a1eb6cf3 | stack      | CREATE_COMPLETE | 2015-10-13T15:27:20 | None         |
+--------------------------------------+------------+-----------------+---------------------+--------------+

查看实例的名称和IP地址并和OpenStack client的输出比较：

$ openstack stack output show --all stack
[
  {
    "output_value": "stack-server-3nzfyfofu6d4",
    "description": "Name of the instance.",
    "output_key": "instance_name"
  },
  {
    "output_value": "10.4.31.106",
    "description": "IP address of the instance.",
    "output_key": "instance_ip"
  }
]

$ openstack server list
+--------------------------------------+---------------------------+--------+---------------------------------+
| ID                                   | Name                      | Status | Networks                        |
+--------------------------------------+---------------------------+--------+---------------------------------+
| 0fc2af0c-ae79-4d22-8f36-9e860c257da5 | stack-server-3nzfyfofu6d4 | ACTIVE | public=10.4.31.106              |
+--------------------------------------+---------------------------+--------+---------------------------------+

删除stack。
```
$ openstack stack delete --yes stack
```
