Heat

Heat是 OpenStack 提供的自動編排功能的組件，基於描述性的模板，來編排復合雲應用程序。Heat 采用了模板方式來設計或者定義編排，為方便用戶使用，Heat 還提供了大量的模板例子，使用戶能夠方便地得到想要的編排

 

創建Flavor

編寫Heat模板create_flavor.yaml，創建名為“m1.flavor”、 ID 為 1234、內存為1024MB、硬盤為20GB、vcpu數量為1的雲主機類型

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      

 

創建Net

編寫Heat模板create_net.yaml，創建名為Heat-Network網絡，選擇不共享；
創建子網名為Heat-Subnet，子網網段設置為10.20.2.0/24，開啟DHCP服務，地址池為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

 

創建volume

編寫Heat模板create_volume.yaml，大小為10G

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

 

創建server

編寫Heat模板create_server.yaml，鏡像為cirros，網絡為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
