Question

想要在项目的值变为7之后中断任务，这是示例任务

   - hosts: localhost
     tasks:
       - shell: echo {{ item }}
         register: result
         with_sequence: start=4 end=16
         when: "{{ item }} < 7"

在上面的代码中，它将任务从4迭代到16，如下所示

PLAY [localhost] ***********************************************************************************************************************************************

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

TASK [command] *************************************************************************************************************************************************
 [WARNING]: when statements should not include jinja2 templating delimiters such as {{ }} or {% %}. Found: {{ item }} < 7

changed: [localhost] => (item=4)
changed: [localhost] => (item=5)
changed: [localhost] => (item=6)
skipping: [localhost] => (item=7)
skipping: [localhost] => (item=8)
skipping: [localhost] => (item=9)
skipping: [localhost] => (item=10)
skipping: [localhost] => (item=11)
skipping: [localhost] => (item=12)
skipping: [localhost] => (item=13)
skipping: [localhost] => (item=14)
skipping: [localhost] => (item=15)
skipping: [localhost] => (item=16)

PLAY RECAP *****************************************************************************************************************************************************
localhost                  : ok=2    changed=1    unreachable=0    failed=0

Ansible运行循环并且：

执行echo命令 - 显示changed状态，
其余项目未执行 - 显示skipped状态，

你已经达到了你想要的目标。

唯一可以改进的是通过修复条件来消除警告：

- hosts: localhost
  tasks:
    - shell: echo {{ item }}
      register: result
      with_sequence: start=4 end=16
      when: "item|int < 7"

如何在Ansible中打破循环？
