Get file(s) from a remote host to local host

[R-JRI]

Hi,

I created a simple yml file to get file or files from a remote host to local host:

$ cat fetch.yml

---
- hosts: serverA

  tasks:
  - name: find the files
    find:
      paths: /usr/local/apps/log
      patterns: AppsAdmin.*.ALLAPPS.20190828*
      use_regex: True
    register: Apps_files

  - debug:
      var: Apps_files.files.path

  - name:
    fetch:
      src: "{{ item }}"
      dest: /APPADMIN/ansible/nonprod/DR_test/
    with_items: "{{ Apps_files.files.path }}"

The variable 'Apps_files.files.path' is getting from the output of debug.

Here is the output when ran it.

[appadmin@serverB][/APPADMIN/ansible/nonprod/DR_test]$ ansible-playbook  fetch.yml

PLAY [serverA] ****************************************************************************************************************************************************************************************************************

TASK [Gathering Facts] **********************************************************************************************************************************************************************************************************************
ok: [serverA]

TASK [find the files] ***********************************************************************************************************************************************************************************************************************
ok: [serverA]

TASK [debug] ********************************************************************************************************************************************************************************************************************************
ok: [serverA] => {
    "Apps_files.files.path": "VARIABLE IS NOT DEFINED!"
}

TASK [fetch] ********************************************************************************************************************************************************************************************************************************
fatal: [serverA]: FAILED! => {"msg": "'list object' has no attribute 'path'"}

PLAY RECAP **********************************************************************************************************************************************************************************************************************************
serverA     : ok=3    changed=0    unreachable=0    failed=1    skipped=0    rescued=0    ignored=0

When debug model only has Apps_files as variable:

-debug:

     var: Apps_files

The output of debug is:

TASK [debug] ********************************************************************************************************************************************************************************************************************************
ok: [serverA] => {

                "xusr": false
            }
        ],
        "matched": 2,
        "msg": ""
    }
}

So I modified variable of 'debug' to 'Apps_files.files.path' for the file name and location that I want to get. Does anyone know why it failed? Thanks.

Your issue is that Apps_files.files is a list, so Apps_files[0].path
would access the path of the FIRST file in that list, which means you
have to extract path for each item to make the fetch loop work:

- name:
fetch:
src: "{{ item }}"
dest: /APPADMIN/ansible/nonprod/DR_test/

loop: "{{ Apps_files.files|map(attribute='path')|list }}"

Thanks, Brian

That works.
