Trying to use the 'find' module to collect a list of files that I will then
operate on. To test this out, I wrote a simple playbook as follows:
- name: test playbook
#remote_user: root
hosts: localhost
tasks:
- name: find all vbox SysV init scripts in /etc/rc[0-6].d
find:
paths: "{{ item }}"
patterns: "^.*virtualbox$"
use_regex: True
with_items:
- /etc/rc0.d
- /etc/rc1.d
- /etc/rc2.d
- /etc/rc3.d
- /etc/rc4.d
- /etc/rc5.d
- /etc/rc6.d
register: vbox_sysv_scripts
- debug: var=vbox_sysv_scripts verbosity=2
- name: Show me the files!
command: ls -l {{ item.path }}
with_items: vbox_sysv_scripts.files
However, when I run the playbook, I get an error on the "Show me the
files!" task, which uses the result of the find registered var:
bash-4.3$ ansible-playbook -i inventory/testing -k test-find.yml
SSH password:

If I print the "vbox_sysv_scripts" var via the debug statement, I get the
following:

Can someone tell me where I'm going wrong here?
When using with_ and register the result is always a list stored in the
<variable>.results, for you that is vbox_sysv_scripts.results, as shown
by you debug
ok: [localhost] => {
"vbox_sysv_scripts": {
"changed": false,
"msg": "All items completed",
"results": [
{
"_ansible_item_result": true,
"_ansible_no_log": false,
"_ansible_parsed": true,
"changed": false,
"examined": 17,
"files": [
The find module add all the files it find per item to a list stored in
vbox_sysv_scripts.results.0.files for the fist item
vbox_sysv_scripts.results.1.files for the second item
vbox_sysv_scripts.results.2.files for the third item and so on.
To get the paths you will have to use the with_subelements: to get them
in your "Show me the files!"
https://docs.ansible.com/ansible/playbooks_loops.html#looping-over-subelements
- name: Show me the files!
command: ls -l {{ item.1.path }}
with_subelements:
- "{{ vbox_sysv_scripts.results }}"
- files
An alternative is to use a list in the module finds paths, then your
"Show me the files!" will work
- name: find all vbox SysV init scripts in /etc/rc[0-6].d
find:
paths: ['/etc/rc0.d', '/etc/rc1.d', '/etc/rc2.d',
'/etc/rc3.d', '/etc/rc4.d', '/etc/rc5.d', '/etc/rc6.d']
patterns: "^.*virtualbox$"
use_regex: True
register: vbox_sysv_scripts
