1.1.4 将Register变量与Loop一起使用 register关键字也可以捕获循环任务的输出。以下代码片段显示了循环任务中register变量的结构: [root@localhost ~]# vim loop_register.yml--- - name: Loop Register Test gather_facts: no hosts: 172.16.103.129 tasks: - name: Looping Echo Task shell: "echo This is ...

Both end up being the same thing, with zip_longest transforming single_list to a list_of_pairs generator. A bit more complex, using set_fact and a loop to create/update a dictionary with key value pairs from 2 lists: Using set_fact to create a dictionary from a set of lists - ...
