2 extra spaces in front of on some rendered lines in for loops

Hi,

I am generating config files and I want them to be indented just so. I started with a jinja2 template that rendered correctly when called from a simple python program. When I call it from ansible, I will get 2 extra spaces on all but the first line of the loop. Generating things like yaml and python has been a real pain. I have taken to putting a comment line as the first line of a for block to fix this…

Here is a really simple example of a yaml generator:
playbook call:

  • name: generate bgp vars file, put in includes directory

local_action: template src={{ role_dir }}/templates/bgp_vars.j2 dest={{ incvar_dir }}/bgp_vars.yaml

run_once: true

section of template:

dc_route_reflectors:

{% for dc in SH_dcs %}

dc is “{{ dc }}”

{{ dc }}:

{% for host in groups[bgpgroupname] if dc == hostvars[host].MYDC %}

  • “{{ hostvars[host].MAIN_MYADDR }}”

{% endfor %}

{% endfor %}

rendered output:

dc_route_reflectors:

dc is “pnp”

pnp:

  • “10.100.16.3”

  • “10.100.32.3”

dc is “sgs”

sgs:

  • “10.8.0.3”

  • “10.8.16.3”

dc is “cst”

cst:

  • “10.4.0.3”

  • “10.4.16.3”

dc is “dse”

dse:

  • “10.200.0.3”

  • “10.200.16.3”

Notice how the pnp comment is not indented as it is shown in the template, but sgs,cst and dse are indented by 2 spaces. All of the array lines of ip addresses are also indented. I have tried various versions of adding “-” to the “%” things as Jinja2 describes, but none have given consistent correct results.

Others must have seen this before. I’m running 2.2.1.0 on centos7.
