How to map variables in the play to variables in the template file?

I have a template file like this.

{
id: “{{ item.id }}”,
url: “{{ item.url }}”,
}

Let say I have two variables looks like this.

var1:

  • a: “id1”,
  • a: “id2”,

var2:

  • b:
    url: “url1”
  • b:
    url: “url2”

Actually they are more complex. I think I have to use with_together. Is there a way to map var1.a to item.id and var2.b.url to item.url?
Because I don’t want the template file to assume the variable names/structures in the play. They might changes in different contexts.

Thank you

with_together or with_nested, depending on whether you want the permutations or them just zipped up together, yeah.

If you have an example of something more complex, it would be helpful to see it.

" Is there a way to map var1.a to item.id and var2.b.url to item.url?"

Don’t understand this part of the question.

"Because I don’t want the template file to assume the variable names/structures in the play. "

If you want the logic in your template instead, it will need to use particular variables. Though I don’t think that’s a problem at all in many cases, you could of course wrap something in a role and pass the list in as input, like so:

  • { role: foo, my_list_one: “{{ alist }}”, my_list_two: “{{ blist }}” }

How to zip those variables in Ansible to new variable?

I want the behaviour similar to this task.

  • template: src=template.j2 dest=output.conf
    with_items:
  • { id: “{{ var1[0].a }}”, url: “{{ var2[0].b.url }}” }
  • { id: “{{ var1[1].a }}”, url: “{{ var2[1].b.url }}” }
    …
  • { id: “{{ var1[n].a }}”, url: “{{ var2[n].b.url }}” }

I haven’t used role. I’ll take a look at it.
