如何在 Ansible 中仅打印非空列表结果

Question

我想在输出（JSON）中只打印非空列表（pog_test）。下面的寄存器输出是另一个先前任务的结果。我什至尝试过使用 when 条件，但没有运气。是否可以在之前的任务本身（已在下面提到任务）中处理此问题，而不是创建一个单独的任务来过滤非空列表。

注册输出

Answer 1

我最初的方法是获取 pog json 文件中的所有详细信息，该文件包含“pog”数组中的一些值。但是现在我用另一种方法来过滤长度== 0的pog数组（代码如下）。

 when:  (item.ansible_facts.pog_match | length == 0 )
