Estou escrevendo meu primeiro manual ansioso agora. Isso é o que eu tenho até agora.
---
- 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
A saída da depuração é:

}
}
Como posso obter o valor
"dest": "/tmp/check-mk-agent-1.5.0p5-1.noarch.rpm",
para continuar trabalhando com ele?
Por exemplo, assim:
- name: Install check_mk
yum:
name: "{{ copied_file.results.dest }}"
state: present

Porque copied_file.results é uma matriz, então, para obter um arquivo único, você deve usar algo assim:
- set_fact: copy_destination={{ copied_file.results[0].dest }}
Ou você pode escrever um loop como este:
- set_fact:
copy_dest = "{{ copy_dest | default([]) | union([item.dest]) }}"
with_items:
- "{{ copied_file.results }}"
Você deve considerar o uso de um fato em vez de uma variável.
- set fact:
copy_destination: "{{ copied_file.results.dest }}"
Você pode acessar o fato usando
"{{ copy_destination }}"
