Get all first level folders of archive module run - ansible

Question

I'm using the archive module to zip some folders and archives.
I need to list all first level folders inside my zip file.
Is there any Jinja or python function to do this using the registered output of the archive module?
My test, so far are:
- name: zip folder
archive:
path:
- /tmp/test/*
dest: /tmp/zipfile.zip
format: zip
mode: "0755"
force_archive: true
register: module_result
Printing module_result, I get:
ok: [host1] =>
msg:
ansible_facts:
discovered_interpreter_python: /usr/bin/python
archived:
- /tmp/test/cfg/1.txt
- /tmp/test/cfg/2.txt
- /tmp/test/cfg/3.txt
- /tmp/test/folder1/folder2/4.txt
- /tmp/test/folder1/folder2/5.txt
Using another task to show my attempts:
- name: list folders
debug:
msg: "{{ item.lstrip(module_result.arcroot).split('/')[0] }}"
# msg: "{{ item }}"
with_items: "{{module_result.archived}}"
I'm trying to cut the first part of the url, using module_result.arcroot on every item that module outputs me and then, a split of the rest of the path, but I get a wrong result. And the worst part is that I'm getting too many times the same folder name.
And the result:
cfg
cfg
cfg
folder1
folder1
My expected result would be:
cfg
folder1
Is this possible?

If your goal is to achieve an unicity on the folders of first level, then the unique Jinja filter is what you are looking for.
Since this filter acts on lists, you would then need to, first, register your results as a list, via the module set_fact.
- name: Making a list out of the files first folder
set_fact:
folders: "{{ folders | default([]) + [(item.lstrip(faked_module_result_arcroot).split('/')[0])] }}"
with_items: "{{ faked_module_result_archived }}"
Then just use the Jinja filter:
- debug:
msg: "{{ folders | unique }}"
Fully working playbook:
---
- hosts: localhost
connection: local
vars:
faked_module_result_archived:
- /tmp/test/cfg/1.txt
- /tmp/test/cfg/2.txt
- /tmp/test/cfg/3.txt
- /tmp/test/folder1/folder2/4.txt
- /tmp/test/folder1/folder2/5.txt
faked_module_result_arcroot: /tmp/test/
tasks:
- name: Making an list out of the files first folder
set_fact:
folders: "{{ folders | default([]) + [(item.lstrip(faked_module_result_arcroot).split('/')[0])] }}"
with_items: "{{ faked_module_result_archived }}"
- debug:
msg: "{{ folders | unique }}"
Would output
PLAY [localhost] ************************************************************************************************************************************************************
TASK [Gathering Facts] ******************************************************************************************************************************************************
ok: [localhost]
TASK [Making an list out of the files first folder] ************************************************************************************************************************

ok: [localhost] => (item=/tmp/test/folder1/folder2/5.txt)

}

Your example works great! I could get some tips and tricks to customize mi script, but for some reason, I'm am getting a strange lstrip behavior when I run the adaptation.
Here is my code:
- name: zip a folder
archive:
path:
- /tmp/test/*
dest: /tmp/{{ path_example | basename }}-files.zip
exclude_path:
- /tmp/test/another_folder
format: zip
mode: "0755"
force_archive: true
register: module_result
- name: First, lstrip result
set_fact:
lstrip_result: "{{ lstrip_result | default([]) [(item.lstrip(module_result.arcroot))] }}"
with_items: "{{ module_result.archived }}"
After run "Archive" task:
ok: [desa01] => changed=false
ansible_facts:
discovered_interpreter_python: /usr/bin/python
archived:
- /tmp/test/cfg/1.txt
- /tmp/test/cfg/2.txt
- /tmp/test/cfg/3.txt
- /tmp/test/folder1/folder2/4.txt
- /tmp/test/folder1/folder2/5.txt
arcroot: /tmp/test/
dest: /tmp/lelo/test-files.zip
expanded_exclude_paths:
- /tmp/test/another_folder
After run "First, lstrip result" task:
TASK [task2: First remove arcroot using lstrip ] ********************************************************************************************************
ok: [desa01] => (item=/tmp/test/cfg/1.txt) => changed=false
ansible_facts:
lstrip_result:
- cfg/1.txt
ansible_loop_var: item
item: /tmp/test/cfg/1.txt
ok: [desa01] => (item=/tmp/test/cfg/2.txt) => changed=false
ansible_facts:
lstrip_result:
- cfg/1.txt
- cfg/2.txt
ansible_loop_var: item
item: /tmp/test/cfg/2.txt
ok: [desa01] => (item=/tmp/test/cfg/3.txt) => changed=false
ansible_facts:
lstrip_result:
- cfg/1.txt
- cfg/2.txt
- cfg/3.txt
ansible_loop_var: item
item: /tmp/test/cfg/3.txt
ok: [desa01] => (item=/tmp/test/folder1/folder2/4.txt) => changed=false
ansible_facts:
lstrip_result:
- cfg/1.txt
- cfg/2.txt
- cfg/3.txt
- st/folder1/folder2/4.txt
ansible_loop_var: item
item: /tmp/test/folder1/folder2/4.txt
ok: [desa01] => (item=/tmp/test/folder1/folder2/5.txt) => changed=false
ansible_facts:
lstrip_result:
- cfg/1.txt
- cfg/2.txt
- cfg/3.txt
- st/folder1/folder2/4.txt
- st/folder1/folder2/4.txt
ansible_loop_var: item
item: /tmp/test/folder1/folder2/5.txt
Here is my problem, with folder cfg everything it is ok, but with folder test, lstrip function is like striping 2 chars more than expected and the result is:
st/folder...
instead of:
test/folder...
Someone gets an idea of this strange lstrip out??
EDIT
lstrip doc says:
Definition and Usage
The lstrip() method removes any leading characters (space is the default leading character to remove)
That's why my output was bad striped, becouse some chars where repited in the string.
I replace lstrip with replace
- name: First, lstrip result
set_fact:
lstrip_result: "{{ lstrip_result | default([]) [(item.lstrip(module_result.arcroot))] }}"
with_items: "{{ module_result.archived }}"
