Heat

Heat是 OpenStack 提供的自动编排功能的组件，基于描述性的模板，来编排复合云应用程序。Heat 采用了模板方式来设计或者定义编排，为方便用户使用，Heat 还提供了大量的模板例子，使用户能够方便地得到想要的编排

 

创建Flavor

编写Heat模板create_flavor.yaml，创建名为“m1.flavor”、 ID 为 1234、内存为1024MB、硬盘为20GB、vcpu数量为1的云主机类型

heat_template_version: 2014-10-16    
resources:                          
  nova_flavor:                      
    type: OS::Nova::Flavor          
    properties:                   
      name: m1.flavor            
      disk: 20                    
      is_public: True              
      ram: 1024                  
      vcpus: 2                  
      flavorid: 1234      

 

创建Net

编写Heat模板create_net.yaml，创建名为Heat-Network网络，选择不共享；
创建子网名为Heat-Subnet，子网网段设置为10.20.2.0/24，开启DHCP服务，地址池为10.20.2.20-10.20.2.100

heat_template_version: 2014-10-16
resources:
  network_1:
    type: OS::Neutron::Net
    properties:
      admin_state_up: true
      name: Heat-Network
      shared: false
  subnet_1:
    type: OS::Neutron::Subnet
    properties:
      allocation_pools:
      - end: 10.20.2.100
        start: 10.20.2.10
      cidr: 10.20.2.0/24
      enable_dhcp: true
      host_routes: []
      name: Heat-Subnet
      network_id:
        get_resource: network_1

 

创建volume

编写Heat模板create_volume.yaml，大小为10G

heat_template_version: 2014-10-16
resources:
  my_new_volume:
    type: OS::Cinder::Volume
    properties:
      size: 10

 

创建server

编写Heat模板create_server.yaml，镜像为cirros，网络为extnet

heat_template_version: 2013-05-23 
description: Test Template
resources: 
  myserver:
    type: OS::Nova::Server
    properties:
      name: "Test Heat server"
      image: { get_param: Image }
      flavor: "2"
      networks:
      - network: { get_param: Net }
parameters:     
  Image:
    type: string
    description: Image use to boot a server
    default：
  Net: 
    type: string
    description: Network ID for the server
    default：
outputs:  
  myserver_private_ip:
    description: IP address of the server in the private network
    value: { get_attr: [ myserver, first_address ] }


# heat stack-create -f create_server.yaml -P Image=cirros -P Net=extnet myserver
