first_found – return first file found from list¶
Synopsis¶
- this lookup checks a list of files and paths and returns the full path to the first combination found.
- As all lookups, when fed relative paths it will try use the current task’s location first and go up the chain to the containing role/play/include/etc’s location.
- The list of files has precedence over the paths searched. i.e, A task in a role has a ‘file1’ in the play’s relative path, this will be used, ‘file2’ in role’s relative path will not.
- Either a list of files _termsor a key files with a list of files is required for this plugin to operate.
Parameters¶
Notes¶
Note
- This lookup can be used in ‘dual mode’, either passing a list of file names or a dictionary that has filesandpaths.
Examples¶
- name: show first existing file or ignore if none do
  debug: msg={{lookup('first_found', findme, errors='ignore')}}
  vars:
    findme:
      - "/path/to/foo.txt"
      - "bar.txt"  # will be looked in files/ dir relative to role and/or play
      - "/path/to/biz.txt"
- name: |
        include tasks only if files exist.  Note the use of query() to return
        a blank list for the loop if no files are found.
  import_tasks: '{{ item }}'
  vars:
    params:
      files:
        - path/tasks.yaml
        - path/other_tasks.yaml
  loop: "{{ q('first_found', params, errors='ignore') }}"
- name: |
        copy first existing file found to /some/file,
        looking in relative directories from where the task is defined and
        including any play objects that contain it
  copy: src={{lookup('first_found', findme)}} dest=/some/file
  vars:
    findme:
      - foo
      - "{{inventory_hostname}}"
      - bar
- name: same copy but specific paths
  copy: src={{lookup('first_found', params)}} dest=/some/file
  vars:
    params:
      files:
        - foo
        - "{{inventory_hostname}}"
        - bar
      paths:
        - /tmp/production
        - /tmp/staging
- name: INTERFACES | Create Ansible header for /etc/network/interfaces
  template:
    src: "{{ lookup('first_found', findme)}}"
    dest: "/etc/foo.conf"
  vars:
    findme:
      - "{{ ansible_virtualization_type }}_foo.conf"
      - "default_foo.conf"
- name: read vars from first file found, use 'vars/' relative subdir
  include_vars: "{{lookup('first_found', params)}}"
  vars:
    params:
      files:
        - '{{ansible_os_distribution}}.yml'
        - '{{ansible_os_family}}.yml'
        - default.yml
      paths:
        - 'vars'

Hint
Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
