Búsqueda ansible de nombres de directorios principales de archivos

Question

Estoy intentando obtener el directorio principal. Nombre de los archivos identificados por un patrón.

base/tool1/sub/test.log
base/tool2/abc/values.log
base/tool3/sub/test.log

Quiero obtener la ruta absoluta de cada directorio, donde se encuentra test.log. así base/tool1/sub/serían base/tool3/sub/las coincidencias que quiero obtener como resultado.

- name: "Loop-Playbook"
  hosts: all
  tasks:

  - name: "Filter File Matches"
    find:
      paths: "/base"
      file_type: "file"
      recurse: "yes"
      patterns: "*test.log"
    register: files_matched

  - name: "Debug files_matched full"
    debug:
var: files_matched.files

  - name: "Debug files_matched items"
    debug:
      var: item.path | dirname 
    loop: "{{ files_matched.files| flatten(levels=1) }}"
    loop_control:
      label: "{{ item.path }}"

Supongo que necesito usar algo como {{ item.path | dirname }}pero, para ser honesto, no tengo idea de DÓNDE tengo que definir esto.

alguien me puede ayudar?

mapa() en JinjaPuede extraer atributos o aplicar un filtro a una secuencia. Utilice ambos para transformar los resultados de la búsqueda en una cadena de filtros.

---
- name: "basename of find results"
  hosts: localhost
  gather_facts: False

  vars:
    testfiles:
    - base/tool1/sub/test.log
    - base/tool2/abc/values.log
    - base/tool3/sub/test.log

  tasks:
  - name: "Set up test case"
    block:

    - tempfile:
        state: directory
      register: mktemp

    - file:
        path: "{{ ( mktemp.path ~ '/' ~ item ) | dirname }}"
        state: directory
      loop: "{{ testfiles }}"

    - file:
        path: "{{ mktemp.path ~ '/' ~ item }}"
        state: touch
      loop: "{{ testfiles }}"


  - name: "Filter File Matches"
    find:
      paths: "{{ mktemp.path }}"
      file_type: "file"
      recurse: "yes"
      # patterns is already matched against basename
      # Do not use a wildcard in front, so only "test.log" matches
      patterns: "test.log"
    register: files_matched

  - name: "Debug files_matched full"
    debug:
       var: files_matched.files
       verbosity: 1

  - name: "Directories found"
    debug:
      msg: "{{ testdirnames }}"
    vars:
      # map to extract an attribute
      # map to apply a filter
      # (it can do either)
      # list filter to consume any generator object returned by Jinja
      testdirnames: "{{ files_matched.files | map(attribute='path') | map('dirname') | list }}"
