Hello, David.
You could use a lookup table implemented as a simple dict. If you only
need it in one task, you can define it in that task's vars section as
I've done below, or farther "up" in host_vars, group_vars, etc., as long
as it's defined somewhere. Here's a simple demo. I'm mapping colors to
veggies, but you could map to file names or whatever. Be sure to handle
the "missing" case.
[utoddl@tango ansible]$*cat select-artifact.yml*
---
- name: Select artifact based on value
hosts: localhost
gather_facts: false
tasks:
- name: Match an artifact based on a value
ansible.builtin.debug:
msg: "Value {{ item }} matches artifact {{*artifacts[item]* |
default('!missing!') }}."
vars:
*artifacts:****green: cucumbers****red: tomatoes****purple:
cabage****yellow: squash*
loop:
- red
- orange
- yellow
- green
- blue
- indigo
- violet
[utoddl@tango ansible]$*ansible-playbook select-artifact.yml*

Hi All,
I'm a DBA learning to use ansible to automate. I'm wondering if
anyone can point me to docs on how to use ansible to select a file
based on the value of a variable. i.e. if variable=x than choose
1.txt if variable=y then choose 2.txt.
Thanks,
David
