Ansible with_items 与循环

Question

使用with_items有什么区别与 loops在安西尔贝？

Answer 1

更新:最新的Documentation列出差异如下

• The with_ keywords rely on Lookup Plugins - even items is a lookup.
• The loop keyword is equivalent to with_list, and is the best choice for simple loops.
• The loop keyword will not accept a string as input, see Ensuring list input for loop: query vs. lookup.
• Generally speaking, any use of with_* covered in Migrating from with_X to loop can be updated to use loop.
• Be careful when changing with_items to loop, as with_items performed implicit single-level flattening. You may need to use flatten(1) with loop to match the exact outcome.

旧答案

根据 docs ,

Before 2.5 Ansible mainly used the with_ keywords to create loops, the loop keyword is basically analogous to with_list.

所以基本上它们几乎是相同的，只是较新的版本在其语法中使用了loop。从版本 2.7.12 开始，两者都按预期工作，但鼓励使用 loop 关键字以实现 future 的兼容性。
