Creating dictionary with same values in all elements - ansible

Question

I have dictionary like this:
abc:
xyz1:
url: "{{ url }}"
api_key: "{{ key }}"
xyz2:
url: "{{ url }}"
api_key: "{{ key }}"
xyz3:
url: "{{ url }}"
api_key: "{{ key }}"
I know that all xyz{number} have the same values in url and api_key and will have same values in the future.
I need this nested format, but what will be more elegant way to write this instead the way I did it (which will be quite long with few more elements)?

Answer 1

Create template
shell> cat myvars.yml.j2
abc:
{% for index in range(1, size+1) %}
xyz{{ index }}:
url: "{{ '{{' }} url {{ '}}' }}"
api_key: "{{ '{{' }} key {{ '}}' }}"
{% endfor %}
The playbook
- hosts: localhost
vars:
size: 3
key: mykey
url: myurl
tasks:
- template:
src: myvars.yml.j2
dest: myvars.yml
- include_vars: myvars.yml
- debug:
var: abc
will create file myvars.yml
shel> cat myvars.yml
abc:
xyz1:
url: "{{ url }}"
api_key: "{{ key }}"
xyz2:
url: "{{ url }}"
api_key: "{{ key }}"
xyz3:
url: "{{ url }}"
api_key: "{{ key }}"
and debug will display the included variable
"abc": {
"xyz1": {
"api_key": "mykey",
"url": "myurl"
},
"xyz2": {
"api_key": "mykey",
"url": "myurl"
},
"xyz3": {
"api_key": "mykey",
"url": "myurl"
}
}
