Referencing a jinja-variable in cmd.run or cmd.shell.

[Tom K.]

Scenario:

{% set mylist = salt['pillar.get']('bigitemlist') %}
{% for block in mylist %}

{% set_var = salt['cmd.run']('cat /some/file | grep -Ei {{ mylist[block][item0] }} | grep blah') %}

... do something ...

{% endfor %}

This errors out, however.  It fails to parse {{ mylist[block][item0] }}  .  A few variations that I've tried include:

{% set_var = salt['cmd.run']('cat /some/file | grep -Ei ' + {{ mylist[block][item0] }} + ' | grep blah') %}

{% set_var = salt['cmd.run']('cat /some/file | grep -Ei '{{ mylist[block][item0] }}' | grep blah') %}

None of these work.  This is Salt 2015.5.  How can I properly reference a salt variable from within cmd.run / cmd.shell?

Thx,

TK

Hi Tom,
as you are already in a Jinja statement you don't need to use {{}} to call a variable. Also you're using shell feature such as pipe so you need to add python_shell option.
I that this will work:

{% set_var = salt['cmd.run']('cat /some/file | grep -Ei ' + mylist[block][item0] + ' | grep blah', python_shell=True) %}

I believe you will also need to do:

{% set set_var = ... %}

HTH,

Dafydd
