Ansible：当 variable/fact 大于或等于 AND 小于或等于？

Question

正如问题所暗示的，如果值大于或等于一个数字且小于或等于另一个数字，我正在尝试评估 Ansible 角色中的事实；基本上是一个范围。我似乎找不到如何执行此操作。

这是我的剧本片段的一部分：

- name: DEBUG Snapshots to be deleted
  debug:
    msg: The snapshot for {{ inventory_hostname.split("_")[0] }} is {{ snap_age }} day(s) old and would have been deleted.
  when: (old_snap is defined) and (old_snap == true) and (snap_age >= "1")

上面的代码确实有效，它 returns 两个项目，一个是 80 天，一个是 102 天。

现在我想获取年龄在 1 到 100 之间的所有快照。我试过这样做：

- name: DEBUG Snapshots to be deleted
  debug:
    msg: The snapshot for {{ inventory_hostname.split("_")[0] }} is {{ snap_age }} day(s) old and would have been deleted.
  when: (old_snap is defined) and (old_snap == true) and (snap_age >= "1" and snap_age <= "100")

但这没有用。然后我尝试了：

- name: DEBUG Snapshots to be deleted
  debug:
    msg: The snapshot for {{ inventory_hostname.split("_")[0] }} is {{ snap_age }} day(s) old and would have been deleted.
  when: (old_snap is defined) and (old_snap == true) and ((snap_age >= "1" and snap_age <= "100"))

这也不起作用，所以我想知道我在这里做错了什么。这一定是我忽略的东西。

这是因为您使用的不是整数而是字符串。

此剧本无效：

- hosts: localhost
  connection: local
  gather_facts: no
  vars:
    old_snap: true
  tasks:
  - name: DEBUG Snapshots to be deleted
    debug:
      msg: The snapshot for {{ inventory_hostname.split("_")[0] }} is {{ item }} day(s) old and would have been deleted.
    when: (old_snap is defined) and (old_snap == true) and (item >= "1" and item <= "100")
    with_items:
    - "80"
    - "102"

但是这个有效:

- hosts: localhost
  connection: local
  gather_facts: no
  vars:
    old_snap: true
  tasks:
  - name: DEBUG Snapshots to be deleted
    debug:
      msg: The snapshot for {{ inventory_hostname.split("_")[0] }} is {{ item }} day(s) old and would have been deleted.
    when: (old_snap is defined) and (old_snap == true) and (item >= 1 and item <= 100)
    with_items:
    - 80
    - 102

如果你不能使用整数，你可以用 intfilter 像 :

- hosts: localhost
  connection: local
  gather_facts: no
  vars:
    old_snap: true
  tasks:
  - name: DEBUG Snapshots to be deleted
    debug:
      msg: The snapshot for {{ inventory_hostname.split("_")[0] }} is {{ item }} day(s) old and would have been deleted.
    when: (old_snap is defined) and (old_snap == true) and (item | int >= 1 and item | int <= 100)
    with_items:
    - "80"
    - "102"

I'm using ansible 2.8.7, command is ansible-playbook <your file>
