使用Ansible URI模块创建OpenStack云主机

创建一个Ansible playbook文件，例如 create_instance.yml，并添加以下内容：

- name: Create instance on OpenStack
  hosts: localhost
  gather_facts: no
  vars:
    openstack_server: "http://openstack.example.com"
    username: "admin"
    password: "password"
    project_name: "admin"
    domain_name: "Default"
    region_name: "RegionOne"
        
    server_name: "new-instance"
    flavor_id: "ecs-2C-4G-40GB"
    key_name: "wanghongwei public key"
    image_id: "05432f95-a1d9-4c55-b1f3-5025b864424d"
    network_id: "6df6996b-920c-41d1-bb79-436a8a5b3f56"
  tasks:
    - name: Get OpenStack token
      uri:
        url: "{{ openstack_server }}:5000/v3/auth/tokens"
        method: POST
        body_format: json
        body:
          auth:
            identity:
              methods:
                - password
              password:
                user:
                  name: "{{ username }}"
                  domain:
                    name: "{{ domain_name }}"
                  password: "{{ password }}"
            scope:
              project:
                name: "{{ project_name }}"
                domain:
                  name: "{{ domain_name }}"
        headers:
          Content-Type: "application/json"
        validate_certs: false
        return_content: true
        status_code: 201
      register: token_response

    - name: Set OpenStack token as a fact
      set_fact:
        openstack_token: "{{ token_response.x_subject_token }}"
      when: token_response.status == 201
    
    - name: Create OpenStack server
      uri:
        url: "{{ openstack_server }}:8774/v2.1/servers"
        method: POST
        headers:
          Content-Type: "application/json"
          X-Auth-Token: "{{ openstack_token }}"
        body_format: json
        body:
          server:
            name: "{{ server_name }}"
            flavorRef: "{{ flavor_id }}"
            imageRef: "{{ image_id }}"
            key_name: "{{ key_name }}"
            networks:
              - uuid: "{{ network_id }}"
        return_content: true
        status_code: 202
      register: create_result
                
    - name: Print OpenStack instances
      debug:
        var: create_result.json

运行Ansible playbook：

ansible-playbook create_instance.yml
