在Ansible jinja2模板中的新行上打印输出

Question

I am struggling with this script to print it's output on new lines. I have tried a few proposed solutions online but none seem to be working. Below is snippet of my playbook.

tasks:
 - debug: msg={% for oct in range(10,12) %}172.16.0.{{ oct }}{% endfor %}

The output i am getting is this

  TASK [debug] *******************************************************************
     ok: [localhost] => {
    "msg": "172.16.0.10172.16.0.11"

I need an output like this

TASK [debug] *******************************************************************
     ok: [localhost] => {
    "msg": "172.16.0.10"
           "172.16.0.11"

I tried insert a \\n like so {% for oct in range(10,12) %}172.16.0.{{ oct }}'\\n'{% endfor %} but that only prints the \\n as a string in my output.

You can't achieve exactly what you want with standard output plugin.

The closest thing is when you print ( debug ) a list – Ansible will print every item on new line:

---
- hosts: localhost
  connection: local
  gather_facts: no
  tasks:
    - debug: msg="{{ lookup('sequence','start=10 end=11 format=172.16.0.%d',wantlist=true) }}"

result:

ok: [localhost] => {
    "msg": [
        "172.16.0.10",
        "172.16.0.11"
    ]
}
