Question

我想在“{{playbook_dir}} / files / 目录中放入一些rpm包，然后复制并安装这些包。据我所知，我可以通过使用寄存器来实现。结果变量。这是我的剧本的一部分：

- name: Copy packages
  copy: src={{ item }} dest=/root/
  with_fileglob:
- "{{ playbook_dir }}/files/*.rpm"
  register: my_pkgs
  loop_control:
    label: "Copy {{ item | basename }}"

- name: Install packages
  yum: name={{ item.path }} state=present
  with_items: "{{ my_pkgs.results }}"
  loop_control:
    label: "Install {{ item.path | basename }}"

在第一次发布时我得到了

TASK [my-role : Install packages] *******************************************************
fatal: [my-host]: FAILED! => {"failed": true, "msg": "the field 'args' has \
an invalid value, which appears to include a variable that is undefined. The \
error was: 'dict object' has no attribute 'path'\n\nThe error appears to have \
been in '/root/ansible/test/roles/my-role/tasks/main.yml': line 9, column 3, but \
may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe \
offending line appears to be:\n\n\n- name: Install packages\n  ^ here\n"}

但是在第二个

TASK [my-role : Install packages] *******************************************************
changed: [my-host] => (item=Install package1.rpm)
changed: [my-host] => (item=Install package2.rpm)

我不明白：我错过了什么吗？这是一个错误还是一个功能？

UPD：ansible-2.3.1.0-1

@techraf是对的：没有path变量，但仅在第一次运行时。在第二次运行path变量时，我会使用dest来表示我的情况。

您不需要在第一项任务中注册任何内容。您可以在两个任务中使用相同的循环。

- name: Copy packages
  copy: src={{ item }} dest=/root/
  with_fileglob:
  - "{{ playbook_dir }}/files/*.rpm"
  loop_control:
    label: "Copy {{ item | basename }}"

- name: Install packages
  yum: name=/root/{{ item | basename }} state=present
  with_fileglob:
  - "{{ playbook_dir }}/files/*.rpm"
  loop_control:
    label: "Install {{ item | basename }}"

Ansible中的results.vars仅在第二次启动时可用
