set, read, and use vars from csv or csv2yml file

[gerard moisset]

i'm trying to write playbook to downlaod packages from repo.

here is my try.

csv data
===========================

cat {{ansibleDir}}/temp/csv_data:

module;goroco;repo
tzdata-26d;G01R01C01;dnc
ansible-26d;G00R00C00;dnc-unstable
webadmi-26d;G01R01C02;dnc-unstable


csv2yml file python script
============================

cat {{ansibleDir}}/csv2yml.py:


#!/usr/bin/env python

import csv
import sys
import yaml

csv_data = []
with open(sys.argv[1]) as csvfile:
    reader = csv.DictReader(csvfile)
    for row in reader:
        csv_data.append(row)

with open(sys.argv[1] + '.yml', 'w') as outfile:
    outfile.write(yaml.dump({'csv_data': csv_data}))



ymlFromCsv file
================================

cat {{ansibleDir}}/temp/csv_data.yml:

csv_data:
- {module;goroco;repo: tzdata-26d;G01R01C01;dnc}
- {module;goroco;repo: ansible-26d;G00R00C00;dnc-unstable}
- {module;goroco;repo: webadmi-26d;G01R01C02;dnc-unstable}


playbook
=================================

try do downlaod package from repo


---
- hosts: localhost
  connection: local
  become: false
  gather_facts: false


  vars_files:
    - /home/ansible/temp/csv_data.yml
  tasks:
    - name: parse csv and make vars file
      command: "python /home/ansible/scripts/csv2yml.py /home/ansible/temp/csv_data"
    - debug: var=csv_data



    - name: define vars
      include_vars:
        file: "/home/ansible/temp/csv_data.yml"
       

missing task
====================================

       
       
       
i need task to be defined either from csv_data, or csv_data.yml, iterating on,

curl -v --remote-name --proxy {{ proxy }} --proxy-user {{ credentials }} {{ downloadUrl }}/{{ delivery.repo }}/{{ delivery.module }}/{{ delivery.goroco }}/PL-{{ delivery.module }}-{{delivery.goroco }}.tar

but i've not yet found the way to reuse my vars.

any help is welcome.

Consider creating a custom vars plugin

What is the exact error message you're getting?

I only slightly agree with Mr. Fellers response ("create a custom vars plugin"), but in your case that might be overkill.  I've seen teams that have a developer write some custom code that breaks soon after he/she leaves and then they are stuck with a bigger mess than if they had tried to work with Ansible included modules.

If you’re having to write Python code already, you’re most of the way to having a custom plugin.  You’re simply doing it in a way that natively hooks into how Ansible works.
