Subject: [ansible-project] Re: Create a variable that contains other variable
values with labels
Here is a solution using regex and map. It's not the most computationally
efficient, but it works.
---
- hosts: localhost
tasks:
- name: set first fact
set_fact:
list1:
- value1
- value2
- name: set second fact
set_fact:
var1: "{{ list1 | map('regex_replace', '^(.*)$','label \\1<file://1>')
| list }} "
- name: print second fact
debug:
var: var1
Regards,
Matt

I have a list:
list1
- value1
- value2
and I want to use set_fact create a new variable that contains these
variables with a label in front of them, so that this debug task:
- debug:
msg: "{{var1}}"
would result in output that looks like this:
label value1
label value2
This gives me the expected results:
- set_fact:
var1: |+
"{{'label ' ~ list1[0]}}"
"{{'label ' ~ list1[1]}}"
But I need more flexibility than that. I need to be able to add or remove
values to or from the list and not have to modify the set_fact task each time
to accommodate the modification. I tried using the join filter:
- set_fact:
var1:
"{{'label ' ~ list1 | join('\n')}}"
And that got me:
label value1
value2
Close, but not quite. So what is the best method of achieving what I want?
