编写 ansible playbook 来创建实例

让我们使用模块’Cloud’中的’os_server’命令[ http://docs.ansible.com/ansible/os_server_module.html] 。变量在 ./group_vars/all 中定义。

$vi launch_compute.yml
- name: launch a compute instance
  hosts: localhost
  gather_facts: False
  tasks:
  - name: Create and launch the VM
    os_server:
      auth:
        auth_url: https://openstack-identity.mycompany.com/v2.0
        username: "{{ AuthUserName }}"
        password: "{{ AuthPassword }}"
        project_name: "{{ TenantName }}"
      state: present
      validate_certs: False
      name: "MyOwnPersonalInstance"
      image: "{{ ImageName }}"
      key_name: "{{ InfraKey }}"
      timeout: 200
      flavor:   "{{ FlavorName }}"
      security_groups: "{{ SecurityGroup }}"
      network: "{{ NetworkName }}"
      auto_ip: yes

$ ansible-playbook  -s launch_compute.yml
[WARNING]: provided hosts list is empty, only localhost is available
