错误！“register”不是播放的有效属性

Question

我对ansible相当陌生，我写了一个剧本，用于检查和安装多台机器的内核升级，但我一直遇到下面的问题。

  *ERROR! 'register' is not a valid attribute for a Play
The error appears to have been in '/etc/ansible/kernel_upgrade/tasks/main.yml': line 4, column 5, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
  - name: View current kernel version
    ^ here*

---
# tasks file for kernel_upgrade

  - name: View current kernel version
    command: uname -mrs
    register: uname_result

  - debug: msg="{{uname_result.stdout_lines}}"
    tags:
      - current kernel versions

  - name: update kernel version
    apt:
      update_cache: yes
      upgrade: dist
      when: ansible_distribution == 'Ubuntu'
      tags:
       - Upgrading kernel Ubuntu

  - name: update kernel CentOS
    yum:
      update_cache: yes
      upgrade: dist
      when: ansible_distribution == 'CentOS'
      tags:
       - Upgrading Kernel CentOS

  - name: Reboot box if kernel/libs updated and requested by the system
    shell: sleep 10 && /sbin/shutdown -r now
    args:
       removes: /var/run/reboot-required
       async: 300
       poll: 0
       ignore_errors: true
       tags:
        - system reboot to apply latest patches


  - name: Wait for system to become reachable again
    wait_for_connection:
      delay: 60
      timeout: 300
      tags:
       - wait for system to become reachable again

  - name: Verify new update
    command: uname -mrs
    register: uname_result
    tags:
       - verifying new update

  - name: Display new kernel version
    debug: msg="{{uname_result.stdout_lines}}"
    tags:
       - new kernel version

我认为问题是你没有正确地定义一组任务，你是试图使用一个角色还是一个常规的游戏？因为你写的结构看起来更像是一个角色，但是给你的错误看起来像是被调用像是一个普通的游戏，而不是一个角色。也许这有助于我想说的：混乱的剧本与角色

我只测试了我这样编写的影响代码，它为我修复了错误，但可以肯定的是，这像一个剧本，而不是像一个角色：

- hosts: localhost

  tasks:
    - name: "View current kernel version"
      command: uname -mrs
      register: uname_result

    - name: print
      debug:
        msg: "{{ uname_result }}"
