Ansible - Iterate Thru Folders Containing Files. Output to file - ansible

Question

Hoping someone might be able to provide me an answer with this. I currently have a folder structure like so.
/BASE_DIR
/FOLDER_A
- file1.txt
- file2.txt
/FOLDER_B
/FOLDER_C
- file3.txt
Im trying to create a playbook that could tell me which folders contain files. My end goal is to have a flat file with:
FOLDER_A, file1.txt
FOLDER_A, file2.txt
FOLDER_C, file3.txt
This is my playbook currently:
- name: get files from all folders
shell: cd /BASE_DIR/{{ item.name }} && ls -p | grep -v / |grep .txt |cat
with_items:
- name: "FOLDER_A"
- name: "FOLDER_B"
- name: "FOLDER_C"
register: "fileitems"
- name: combine to have folder name as key, filenames as values
set_fact:
folders_with_files: "{{ folders_with_files|default({}) | combine( { item.item.name: item.stdout_lines } ) }}"
with_items: "{{ fileitems.results }}"
when: "{{ item.stdout_lines|length }} > 0"
- debug:
var: folders_with_files
I thought I could iterate through each folder looking for *.txt and then use a combine, it would be an easy way to iterate.
ok: [localhost] => {
"folders_with_files": {
"FOLDER_A": [
"file1.txt",
"file2.txt"
],
"FOLDER_C": [
"file3.txt"
]
}
}
But even with this output, I don't think I can properly parse it the way I need to. I thought maybe a nested loop could help, but that would mean I would need to know the name of the keys beforehand.
Any help would be appreciated!
Thanks,
T

Go figure as soon as I post the question, I find my own answer...
I decided to remove the combine and just append to an empty list.
- set_fact:
folders_with_files: []
- name: get all sql from each adapter
shell: cd /tmp/{{ item.name }} && ls -p | grep -v / |grep .txt |cat
with_items:
- name: "FOLDER_A"
- name: "FOLDER_B"
- name: "FOLDER_C"
register: "fileitems"
- name: combine to display which adapters have files
set_fact:
folders_with_files: "{{ folders_with_files + [{ 'name': item.item.name, 'files': item.stdout_lines }] }}"
with_items: "{{ fileitems.results }}"
when: "{{ item.stdout_lines|length }} > 0"
- debug:
var: folders_with_files
My output then became:
ok: [localhost] => {
"folders_with_files": [
{
"files": [
"file1.txt",
"file2.txt"
],
"name": "FOLDER_A"
},
{
"files": [
"file3.txt"
],
"name": "FOLDER_C"
}
]
}
I could then use a with_subelements:
- name: echo
shell: echo "{{ item.0.name }}, {{ item.1}}" >> /tmp/output.txt
with_subelements:
- "{{ folders_with_files }}"
- files
