Controlling indentation in Jinja2 template with Ansible - ansible

Question

I have this playbook:
(venv) bash-3.2$ cat playbooks/nginx_config_generate.yml
---
- name: Generate Nginx Config
hosts: all
gather_facts: False
roles:
- ../roles/nginx_config_generate
Here is the files that make up the role:
(venv) bash-3.2$ cat roles/nginx_config_generate/tasks/main.yml
---
- name: Generate Nginx Config
import_tasks: gen_config.yml
(venv) bash-3.2$ cat roles/nginx_config_generate/tasks/gen_config.yml
- name: Generate Nginx Config File From Template
ansible.builtin.template:
src: sp.conf.j2
dest: "/tmp/nginx.cfg"
(venv) bash-3.2$ cat roles/nginx_config_generate/templates/sp.conf.j2
something here
# Upstreams
{% for ups in my_vars.upstreams %}
{{ ups.entry }}
{% endfor %}
# HTTP Insecure
server {
blha blah blah
something here = that
this = that
{% for ups in my_vars.http_locations %}
{{ ups.entry }}
{% endfor %}
}
Here are my host_vars ...
(venv) bash-3.2$ cat inventory/prod/sfo/host_vars/127.0.0.1
my_vars_str: "host,127.0.0.1,srv1,srv2"
my_vars:
upstreams:
- entry: |
upstream something {
foo: blah blah
}
- entry: |
upstream completely {
foo: blah blah
different: True
}
http_locations:
- entry: |
location / {
set something
}
- entry: |
location /foo {
set something
hover: craft
}
When I run my play it produces this file:
(venv) bash-3.2$ cat /tmp/nginx.cfg
something here
# Upstreams
upstream something {
foo: blah blah
}
upstream completely {
foo: blah blah
different: True
}
# HTTP Insecure
server {
blha blah blah
something here = that
this = that
location / {
set something
}
location /foo {
set something
hover: craft
}
}
As you can see the above is probably a valid nginx config but how can I fix up the indentation on my location lines to make it more readable?
UPDATE: I tried Carlos's suggestion so I have tried this:
...
# HTTP Insecure
server {
blha blah blah
something here = that
this = that
{% for loc in my_vars.http_locations %}
{{ loc.entry }}
{% endfor %}
}
But that yields the same output:
# HTTP Insecure
server {
blha blah blah
something here = that
this = that
location / {
set something
}
location /foo {
set something
hover: craft
}

Answer 1

Ok. I am started playing with the indent filter in my template. Here is the template I am using to generate the output I wanted:
something here
# Upstreams
{% for ups in my_vars.upstreams %}
{{ ups.entry }}
{% endfor %}
# HTTP Insecure
server {
blha blah blah
something here = that
this = that
{% for loc in my_vars.http_locations %}
{{ loc.entry | indent(4)}}
{% endfor %}
}
Now I get this output:
something here
# Upstreams
upstream something {
foo: blah blah
}
upstream completely {
foo: blah blah
different: True
}
# HTTP Insecure
server {
blha blah blah
something here = that
this = that
location / {
set something
}
location /foo {
set something
hover: craft
}
}

Answer 2

have you tried modifying the indentation in the second loop?
# HTTP Insecure
server {
blha blah blah
something here = that
this = that
{% for ups in my_vars.http_locations %}
{{ ups.entry }}
{% endfor %}
}
