Ansible - 查询 VM 磁盘信息并确定可用的控制器/磁盘

如何解决Ansible - 查询 VM 磁盘信息并确定可用的控制器/磁盘

环境：

ansible 2.10.7
config file = /app/ansible/ansible_linux_playbooks/ansible.cfg
configured module search path = ['/etc/ansible/library/modules']
ansible python module location = /usr/local/lib/python3.6/site-packages/ansible
executable location = /usr/local/bin/ansible
python version = 3.6.8 (default,Aug 24 2020,17:57:11) [GCC 8.3.1 20191121 (Red Hat 8.3.1-5)]

因此，我有一项任务是通过 community.vmware.vmware_guest_disk_info 模块验证当前针对 VMware VM 使用的控制器和磁盘。

该模块的输出如下所示：

TASK [vcsa_add_guest_disk : vm_guest_disk_info_gather] *******************************************************************************************************************************************************************

        },"1": {

        }
    }
}

我通过以下方式提取分配给每个 VM 的控制器编号和 scsi 磁盘：

- name: debug_guest_disk_info
  debug:
    msg: "{{ reg_vm_guest_disk_info_gather | to_json | from_json | json_query(jmesquery) }}"
  vars:
    jmesquery: "guest_disk_info.*.{key: controller_bus_number,value: unit_number}"
  register: results1

输出：

TASK [vcsa_add_guest_disk : debug_guest_disk_info] ***********************************************************************************************************************************************************************
task path: /app/ansible/ansible_linux_playbooks/roles/vcsa_add_guest_disk/tasks/verify_guest_disk_info.yml:14
Monday 22 March 2021  09:31:16 -0400 (0:00:00.874)       0:00:04.573 ********** 
ok: [testserver06.tlb1.local.net] => {}

MSG:

[{'key': 0,'value': 0},{'key': 2,'value': 1}]

我可以确定下一个/可用的控制器编号：

- name: debug_results
  debug:
    msg:
      - "What is missing: {{ scsi_controller_max | difference(results1|to_json|from_json|json_query('msg[*].key') | map('int') | list ) }}"

  vars:
    - scsi_controller_max: "{{ range(4) | map('int') | list }}"
    - scsi_drive_max: "{{ range(15) | map('int') | list }}"

输出：

TASK [vcsa_add_guest_disk : debug_results] *******************************************************************************************************************************************************************************
task path: /app/ansible/ansible_linux_playbooks/roles/vcsa_add_guest_disk/tasks/verify_guest_disk_info.yml:22
Monday 22 March 2021  09:31:16 -0400 (0:00:00.176)       0:00:04.749 ********** 
ok: [testserver06.tlb1.local.net] => {}

MSG:

['What is missing: [1,3]']

所以我知道下一个控制器（如果我需要/想要添加一个），将是 1 或 3。

问题/问题：

我不知道如何组合“results1”或“disk_info”输出来映射每个控制器上缺少的驱动器（可用的unit_number）以供使用。

• 不能使用“计数”来确定，因为这只能给我多少个驱动器 有吗

• 不能使用'max'，因为这不会考虑如果 驱动器依次丢失

我一直无法弄清楚如何组合“列表字典”（我相信我想要的，但甚至不确定）。

我想数据看起来会像这样：

[{'key': 0,'value': [0,1]}]

谢谢
