Pause只为播放批次运行一次，导致只有批次中的第一个服务器(在我的情况下为1.1.1.1(选择变量。

你可以通过在你的剧本中添加序列来解决这个问题，如下所示：

---
- name : find the results for migration ended
hosts: newmigservers
serial: 1
tasks:
- pause:
prompt: "what is the container name?"
echo: yes
register: result
- set_fact:
container: "{{ result.user_input }}"
- debug:
var: container
