[ Ansible ] - Weird nested loop help

[João Santos]

Hey community, need your help again...

On my goal of automation I'm blocked on loops... dont know if I'm doing wrong, need to change approach or if just stupid...

Well, lets try...

I would like to replace lines in FILES_A with lines that are on MAPPING_A.

  - name: Add values from MAPPING_A to FILES_A

    lineinfile:

      path: "/PATH_TO/FILES_A/{{ item.0 | basename }}"

      line: "{{ item.1 }}"

      insertafter: "^(.*){{ item.1.split('=') | first }}"

    with_nested:

      - "{{ lookup('fileglob', '/PATH_TO/MAPPING_A/*.TXT') }}"

      - "{{ lookup('file', '/PATH_TO/MAPPING_A/{{ item.0 | basename }}.TXT').splitlines() | select() | list }}"

Allow me to give more insight of what I want to achieve with that loop:

"{{ lookup('fileglob', '/PATH_TO/MAPPING_A/*.TXT') }}"

^^ want to list all files on that folder, because I will need to collect filename - thats the reason why i have "{{ item.0 | basename }}" at path - that would be what I use to identify which files I want to change.

If files exists in that folder will contain content to replace on a diferent destination and filename is what I'm using. If filename exists on both sides will collect content and insert it.

so that will be the first loop

"{{ lookup('file', '/PATH_TO/MAPPING_A/{{ item.0 | basename }}.TXT').splitlines() | select() | list }}"

^^ Ok, after the first loop is in place (list of which files to edit), now on the second loop I need to per file to read content in order to replace on the destination.

What is happening?

Maybe its not supposed to... Ansible is not recognizing "{{ item.0 | basename }}" at second loop....

Well... ¯\_(ツ)_/¯ again... I'm stuck, can anyone share thoughts/suggestions with me?

You don't show no evidence of what are you trying to automate :-(.

At any rate it doesn't make sense to use "item" inside the loop definition.

Hey thanks for your comment regarding automation, it's very useful.

Might not make sense to you and that's the reason why I explained with details - was to explain what I'm trying to achieve, what I'm trying but without success and with expectations that someone could share more than you had done.

Thanks again.

Not so obvious to understand...

Perhaps you should try progressive steps and not wanting to do everything in one unique step

To look for specific file, perhaps you should use the find module with a register

And after loop on these files using the variable registered before...
