Question

在我目前的剧本中，我有以下内容：

- name: Copy cov-analysis-linux64-8.0.0.tgz
  copy: src=/home/devops/chroot/cov-analysis-linux64-8.0.0.tgz                     dest=/var/tmp/cov-analysis.tgz owner=devops
  register: coverity

- name: Copy fortidev-2.02.chroot.tar.bz2
  copy: src=/home/devops/chroot/fortidev-2.02.chroot.tar.bz2
  dest=/var/tmp/fortidev2.chroot.tar.bz2 owner=devops
  register: fortidev2

列表越来越长，为了代码可读性，我想使用with_items来完成它。我把它更新为：

- name: copy chroot tarball to the servers
  copy: src={{ item.src }} dest={{ item.dest }} owner=devops
  register: "{{ item.register }}"
  with_items:
    - { src: /home/devops/chroot/cov-analysis-linux64-8.0.0.tgz, 
        dest: /var/tmp/cov-analysis.tgz,
        register: coverity
      }
    - { src: /home/devops/chroot/fortidev-2.02.chroot.tar.bz2,
        dest: /var/tmp/fortidev2.chroot.tar.bz2,
        register: fortidev2
      }
    - { src: /home/devops/chroot/fmdev-6.0.tar.xz,
        dest: /var/tmp/fmdev6.tar.xz,
        register: fmdev6
      }

问题是，当我想在后续任务中引用其中一个寄存器时，它找不到变量。引用它的代码是：

- name: umount fortidev2 /proc|/dev|/tmp|/cov-analysis 
  command: umount {{ item }}
  become: yes
  when: fortidev2.changed
  with_items:
          - /home/devops/fortidev2/proc
          - /home/devops/fortidev2/dev
          - /home/devops/fortidev2/tmp
  ignore_errors: yes

错误是 {“failed”：true，“msg”：“条件检查'fortidev2.changed'失败。错误是：评估条件时出错（fortidev2.changed）：'fortidev2'未定义\ n \ n错误似乎是在'/var/lib/jenkins/jobs/Devops/jobs/update_chroot/workspace/roles/chroot/tasks/main.yml'：第70行第3列，但可能在文件的其他位置，具体取决于确切的语法问题。\ n \ n违规行似乎是：\ n \ n＃unmount / proc和/ dev首先删除文件夹\ n-名称：umount fortidev2 / proc | / dev | / tmp | / cov-analysis \ n ^这里\ n“个}

试试这个：

- name: copy chroot tarball to the servers
  copy: src={{ item.src }} dest={{ item.dest }} owner=devops
  register: tarballs
  with_items:
    - { src: /home/devops/chroot/cov-analysis-linux64-8.0.0.tgz, 
        dest: /var/tmp/cov-analysis.tgz,
        name: coverity
      }
    - { src: /home/devops/chroot/fortidev-2.02.chroot.tar.bz2,
        dest: /var/tmp/fortidev2.chroot.tar.bz2,
        name: fortidev2
      }
    - { src: /home/devops/chroot/fmdev-6.0.tar.xz,
        dest: /var/tmp/fmdev6.tar.xz,
        name: fmdev6
      }

- name: umount fortidev2 /proc|/dev|/tmp|/cov-analysis 
  command: umount {{ item }}
  become: yes
  when: tarballs.results | selectattr('item.name','equalto','fortidev2') | join('',attribute='changed') | bool
  with_items:
    - /home/devops/fortidev2/proc
    - /home/devops/fortidev2/dev
    - /home/devops/fortidev2/tmp
