Ansible - 如何在輸出中選擇元素

我是一周前剛開始接觸 ansible 的新手。我在玩劇本和臨時命令 我執行臨時命令 ansible ansiblenodes -m setup -a “filter=ansible_mounts”

192.168.75.31 | SUCCESS => {
   "ansible_facts": {
       "ansible_mounts": [
           {
               "block_available": 217708,
               "block_size": 4096,
               "block_total": 259584,
               "block_used": 41876,
               "device": "/dev/sda1",
               "fstype": "xfs",
               "inode_available": 523952,
               "inode_total": 524288,
               "inode_used": 336,
               "mount": "/boot",
               "options": "rw,seclabel,relatime,attr2,inode64,noquota",
               "size_available": 891731968,
               "size_total": 1063256064,
               "uuid": "8a896a10-d8b0-4c95-9743-69b213b47f5a"
           },
           {
               "block_available": 2145829,
               "block_size": 4096,
               "block_total": 3273216,
               "block_used": 1127387,
               "device": "/dev/mapper/rhel-root",
               "fstype": "xfs",
               "inode_available": 6400742,
               "inode_total": 6551552,
               "inode_used": 150810,
               "mount": "/",
               "options": "rw,seclabel,relatime,attr2,inode64,noquota",
               "size_available": 8789315584,
               "size_total": 13407092736,
               "uuid": "9fe9a7c9-613e-428d-b255-93f0006cf9ad"
           }
       ],
       "discovered_interpreter_python": "/usr/bin/python"
   },
   "changed": false
}

現在，如果我想編寫一本劇本，我應該如何提及僅顯示掛載點及其可用空間。

我假設您只想顯示此數據而不對其執行任何操作：

---

- hosts: all
 tasks:
   - name: show filesystems
     debug:
       msg: "mount: {{ item.mount }}, available: {{ item.size_available | human_readable }}"
     loop: "{{ ansible_mounts }}"
     loop_control:
       label: ""

該劇本將顯示掛載點和可用大小。我使用 loop_control 在 Ansible 輸出中不顯示具有所有屬性的每個項目。
