Create a variable that contains other variable values with labels

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?

Here is a solution using regex and map. It’s not the most computationally efficient, but it works.

Whatever works is what counts.
