Question

从我以前的《 Playbook》中更加清楚。我正在尝试传递2个交换机IP，以获取两个交换机上的可用端口。当我尝试传递一个交换机IP时，它执行得很好。当我尝试通过拆分“ SPACE”传递2个IP的分隔时，它仅在第一个交换IP上执行。但是不使用第二个IP。请参阅执行输出和相应的剧本 Ansible版本：2.6.1

Answer 1

    switch_ip: "{{ip_addr}}"

该值是提示符下的值，因此包含您输入的以空格分隔的版本。

我认为您想要的是将with_items:移至实际任务，因为add_host:不会更改hosts: localhost的执行计划：

- name: display all available ports
  display_available_ports:
      switch_ip: "{{item}}"
      # etc
  with_items: "{{ip_addr.split(' ')}}"

Ansible vars_prompt＆with_items和split
