Ansible Jinja indentation bug ?

[Nicolas G]

Hi,

I have the bellow vars to populate a template , it works almost fine but the final file result you can see there is some indentation problem :

# vars :

datadog_http_checks:

  - name : mycheck

    url : http://localhost:9090/hc/

    threshold : 5

    window : 5

    timeout : 1

# template:

init_config:

instances:

{% for http in datadog_http_checks %}

- name: {{ http.name }}

  {% if http.url is defined -%}

  url: {{ http.url }}

  {% endif -%}

  {% if http.threshold is defined -%}

  threshold: {{ http.threshold }}

  {% endif %}

  {% if http.window is defined -%}

  window: {{ http.window }}

  {% endif %}

  {% if http.timeout is defined -%}

  timeout: {{ http.timeout }}

  {% endif %}

  {% if http.include_content is defined -%}

  include_content: {{ http.include_content }}

  {% endif %}

  notify:

    - pagerduty

{% endfor %}

# result :

instances:

- name: mycheck

  url: http://localhost:9090/hc/

  threshold: 5

    window: 5

    timeout: 1

      notify:

    - pagerduty

Is this a bug or am I doing something wrong ?

The problem from what I can remember is that ansible does not specify lstrip_blocks, and as such, it can cause indentation issues.

The approach I take, it to left justify all jinja2 control blocks.  So all {% %} lines would have no indentation, only the lines inside would be indented.

such as:

{% for http in datadog_http_checks %}

- name: {{ http.name }}

{% if http.url is defined -%}

    url: {{ http.url }}

{% endif -%}

    ...

{% endfor %}
