uri_module POST with template as body, is it possible?

Hello!

I’m trying to make a task that uses a REST api to do some final configuration of a previously installed component.
I want to make a POST request with a body that is a template that uses host specific variables.

The closest i’ve come up with is the following:

  • name: Adding datasource via http api
    uri:
    url: http://{{ inventory_hostname }}:3000/api/datasources
    method: POST
    body_format: json

HEADER_Content-Type: “application/json”
body: “{{ lookup(‘file’ , ‘roles/grafana/templates/datasource.json.j2’) }}”

which sends the template-file as body, but unfortunately without any variables substituted…

Any idea how i should approach the problem?

I believe that using the template lookup instead of the file lookup is
what you want. So something like:

   body: "{{ lookup('template',
'roles/grafana/templates/datasource.json.js') }}"

Thanks for the help Toshio, i have verified that using the template lookup does exactly what I want!

To help others, also note that the path to the template is relative to the location of the task file that invoked it.

Even I’ve tried with same approach, but getting an error. Can you show the content of datasource.json.j2 file

Thanks!

One could even skip the roles/grafana/templates/ part in the lookup:

body: "{{lookup('template', 'http/updateRepository.txt')}}"
