我有json格式的ansible_devices变量，我只想得到一些特定大小的磁盘名称列表。我尝试在this howto之后使用json_query和filter，但我无法获取数据，变量my_disks为空。但是如果我不使用json_query过滤器，它会在下面用json填充。

- name: set facts
      vars:
        query_disks: "[?sectors==`7814037168`].dev"
      set_fact:
        my_disks: "{{ ansible_devices | json_query('[?sectors==`7814037168`]') }}"

    - name: print found disks with specific size 7814037168
      debug:
        msg:
          - my_disks "{{ my_disks }}"

JSON：

我发现其他solution：

- name: set facts
      set_fact:
       my_disks: "{{ ansible_devices | dict2items | selectattr('key', 'match', '^sd.*') | rejectattr('key', 'match', '^sda$') | selectattr('value.size', 'match', '^3.64 TB') | map(attribute='key') | list }}"
ok: [server] => {
    "ansible_facts": {
        "my_disks": [
            "sdd",
            "sdb"
        ]
    },
    "changed": false
}

谢谢！
