我怎样才能正确完成ansible playbook来获取我想要的信息

Question

我是 ansible 的新手，所以我需要帮助来完成我的第一本 ansible 剧本我需要从在日志目录下创建的文件中获取结果。我还需要输入容器名称，该名称已迁移以查找以容器命名并以 1 和 3 开头的结果文件（需要 2 个文件结果）找不到哪个部分出错了。请帮帮我提前谢谢你。

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

    - name: find where the container is
      shell: "grep -lr '{{ container }}'"
      args:
        chdir: "logs/"
      register: grep_output

- name: cat 1,3 file for the results
  command: cat {{ grep_output }}
  register: results

what is the container name?:

暂停只为播放批次运行一次，导致批次中只有第一个服务器（1.1.1.1 在我的例子中）选择变量。

您可以通过向剧本添加序列号来解决此问题，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
