Accessing Cfg file values within nested loops + using sections + passing section in cmd argument

[Akshay Kumar]

Hi All,

Hope all is well with everyone during these bad times because of covid :-).

I would like to know some good advices from the community on a scenario am working on , it goes as followed:

Cfg file:

SectionA:

    ls:

       dirname: <dirPath>

       Command: List

    cp:

      srcdirname: <path>

      tgtDirname: <path>

      command: copy

SectionB:

    ls:

      dirname: <dir path>

      command: List

And in playbook right now i am accessing it using with_dict  and include_vars but i am not able to use cmd line argument for "section" for eg if i say 

ansible-playbook playbook.yaml -e section=SectionA  

Any suggestions of how we can access the values of dicts by first checking the section of Cfg file which is passed on cmd line and then performing action according to the command in the dict values.

Thanks in advance for your response .

This is too abstract to comment on in a useful way.
What does "not able to use" mean - does it fail?
Please provide the real, actual, working playbook and try to use less
opaque terms.

Also, what is the overall goal you are trying to achieve?
From the little information you've shared, the closest I can guess is
"copy some configuration file(s)".
Please share that as well.

Hi D.Visser,

Sorry for not being able to share the info properly , i am using the below playbook 

- hosts: localhost

  vars_files:

    - "{{ config }}.cfg"

  tasks:

  - name: run ls

    shell: "'{{ item.command }}' '{{ item.dir }}'"

    when: "'{{ item.command }}' == 'ls'"

    with_items: "{{ SectionA }}"

cfg file -----------

SectionA:

  first:

    DirName:  /home/kumar/DevFileTestLocation

    Command: ls

SectionB:

  ls:

    Second:

      DirName:  /home/kumar/Dev

So when i call ansible-playbook playbook.yaml , it works because i am calling test SectionA directly in the playbook under with_items but if am running command like

ansible-playbook playbook.yaml -e section=SectionA , so that my dict is picked automatically via cmd line , it doesnt work.

I want that flexibility so that i can call playbook on the basis if my sections and use data within those sections.

also i just want to know if there is any other way to use the data in sections when i set cmd line param using section=SectionA/SectionB.

Thanks
