Question

我正在尝试使用ansible代码段提取vm数据存储的值：

- name: Gather disk facts from virtual machine using name
       vmware_guest_disk_facts:
          hostname: "{{ vcenter_server }}"
          username: "{{ vcenter_user }}"
          password: "{{ vcenter_pass }}"
          datacenter: "{{ datacenter }}"
          validate_certs: no
          name: "{{ item }}"
       delegate_to: localhost
       register: disk_facts
       with_items: "{{ vm_list }}"

     - name: Get disk info
       debug:
         var: disk_facts.results.guest_disk_facts.backing_datastore

输出：

[root@sysmgttl1 lvm]# ansible-playbook -i hosts vmfacts.yml -e vcenter_server=vmimgtpw002 -e vm_list=sndprfql8

PLAY [sndprfql8] ***********************************************************************************************************************************************************

TASK [Gathering Facts] *****************************************************************************************************************************************************
ok: [sndprfql8]

TASK [Gather disk facts from virtual machine using name] *******************************************************************************************************************
ok: [sndprfql8 -> localhost] => (item=sndprfql8)

TASK [Get disk info] *******************************************************************************************************************************************************
ok: [sndprfql8] => {
    "disk_facts.results.guest_disk_facts.backing_datastore": "VARIABLE IS NOT DEFINED!"
}

PLAY RECAP *****************************************************************************************************************************************************************
sndprfql8                  : ok=3    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

这就是我的disk_facts的样子。

                "item": "sndprfql8"
            }
        ]
    }
}

如果这确实是一次使用，则应执行以下操作：

- name: Get disk info
  debug:
   var: disk_facts.results[0].guest_disk_facts['0'].backing_datastore

如果您的目标是获取结果中可能有多个磁盘的vms列表的所有值，则以下内容将为您提供扁平化的列表（如果需要，可以使用unique过滤器进行重复数据删除）

- debug:
    msg: "{{ disk_facts | json_query('results[].guest_disk_facts.*[].backing_datastore') }}"

我正在尝试使用ansible找到vm guest虚拟机的数据存储
