使用Ansible将引导磁盘（如果存在）连接到Gcloud实例

我正在使用Ansible在谷歌云中创建实例，但当我想将现有磁盘连接到新的计算引擎时，我无法将其连接或添加到实例

- name: Launch instances
  gce:
    instance_names: mongo
    machine_type: "n1-standard-1"
    image: "debian-9"
    service_account_email: "xxxx@xxxx.iam.gserviceaccount.com"
    credentials_file: "gcp-credentials.json"
    project_id: "learning"
    disk_size: 10
    disk_auto_delete: false
    preemptible: true
    tags: "mongo-server"
  register: gce

- name: Wait for SSH for instances 
  wait_for:
    delay: 1
    host: "{{ item.public_ip }}"
    port: 22
    state: started
    timeout: 30
  with_items: "{{ gce.instance_data }}"

我的错误是：

错误为：libcloud.common.google.resourceExistError:{'domain'：'global'，'message'：'The resource'projects/xxx xxx/zones/us-central1-a/disks/mongo'已存在'，'reason'：'alreadyExists'}

是否有任何表单可以使用Ansible配置此选项？为此，我现在使用外部脚本。

现有磁盘可以作为“磁盘”属性下的列表提供，第一个条目需要是Boot-dik

  - gce:
  instance_names: my-test-instance
  zone: us-central1-a
  machine_type: n1-standard-1
  state: present
  metadata: '{"db":"postgres", "group":"qa", "id":500}'
  tags:
    - http-server
    - my-other-tag
  disks:
    - name: disk-2
      mode: READ_WRITE
    - name: disk-3
      mode: READ_ONLY
