我现在正在写我的第一本 ansible 剧本。这就是我到目前为止所拥有的。

- hosts: kolumbus become: yes
tasks:
- name: Copy RPM
copy:
src: "{{ item }}"
dest: /tmp
with_fileglob:
- /opt/omd/versions/default/share/check_mk/agents/check-mk-agent-*.noarch.rpm
register: copied_file
- debug: var=copied_file
调试的输出是：

"uid": 0
}
]
}
}
我怎样才能得到价值
"dest": "/tmp/check-mk-agent-1.5.0p5-1.noarch.rpm",
继续使用它？
例如这样：
- name: Install check_mk
yum:
name: "{{ copied_file.results.dest }}"
state: present
更新这是我当前的剧本

答案1
因为copied_file.results是一个数组，所以要获取单个文件的目标，您应该使用如下所示的内容：
- set_fact: copy_destination={{ copied_file.results[0].dest }}
或者你可以写一个像这样的循环：
- set_fact:
copy_dest = "{{ copy_dest | default([]) | union([item.dest]) }}"
with_items:
- "{{ copied_file.results }}"
答案2
您应该考虑使用事实而不是变量。
- set fact:
copy_destination: "{{ copied_file.results.dest }}"
然后您可以使用以下方式访问事实
"{{ copy_destination }}"
