How to insert ansible dictionary variable as yaml in template output file

Question

I have this dictionary

env2:
  a: 20
  b: 50
  d: 90

Now i have this template file

name: "test"

env: "{{ env2 | to_nice_yaml(indent=8) }}"

When i run the playbook i get output as

env: "a: 20
b: 50
d: 90
"

how can i get output as

env:
  a: 20
  b: 50
  d: 90

Answer 1

Use the Jinja filter indent. For example, the template below

shell> cat test.yml.j2
name: test

env:
  {{ env2|to_nice_yaml|indent(2) }}

and the playbook

- hosts: localhost

  vars:

    env2:
      a: 20
      b: 50
      d: 90

  tasks:

    - template:
        src: test.yml.j2
        dest: /tmp/test.yml

create the file

shell> cat /tmp/test.yml
name: test

env:
  a: 20
  b: 50
  d: 90
