Setting conditional variables in map.jinja

[HRX]

Hi,

Saltstack newbie, at my wit's end.

Trying to set variables in map.jinja based on values received from pillar data:

map.jinja:

{% set vars = {

  {% if salt['pillar.get']('ec2:tags:application') == 'jboss' %}

  'admingroup': 'jbossadmins'

  {% end if %}

}

%}

Then call this from a state file

...

{% set admin = vars.admingroup %}

And I will use {{ admin }} where I need to.

This produces an error with:

Rendering SLS failed:  Jinja syntax error: unexpected '%'

 {% if salt['pillar.get']('ec2:tags:application') == 'jboss' %}  <======================

I could not figure out what is wrong. 

What is the recommended approach for setting variables based on values obtained from pillars?

Thank you.

I figured out the issue, I was using "--local" to test the setup locally but my pillar was not local.

So I created a local copy for pillar and now this works.

But for the best practice question, I was told I can not call pillar.get from inside a pillar file, where should we setup variables based on values obtained from pillars?

Thanks

You don't need Jinja tags when you're already inside of a tag. And
once you're inside a tag, Jinja semantics are roughly equivalent to
Python. Here are two possible approaches:

{# option 1 #}
{% set vars = {
'admingroup': 'jbossadmins'

if salt['pillar.get']('ec2:tags:application') == 'jboss'

else 'defaultvalue',
} %}

{# option 2 #}

{% set vars = {} %}
{% if salt['pillar.get']('ec2:tags:application') == 'jboss' %}

{% do vars.update({'admingroup': 'jbossadmins'}) %}
{% endif %}

Is the map file you're working on used in States or in Pillar? If it's
used in States then what you're doing is fine and even common.

It is true you cannot reference other Pillar values from within a
Pillar SLS file. Using Jinja imports is a quick way around that. See
the discussion below for examples of that.

Seth, thanks a lot! I used second option and it works very well as I am setting additional variables per pillar match.
