When I try the other version

{% set postdata = data.get('post', {}) %}

#{% if postdata.secretkey == "jenkins2salt" %}


pingtest:
  cmd.cmd.script:
   - tgt: base-lj-3
   - fun test.ping
   - kwarg:
       user: root
       group: root

#{% endif %}

I get  nothing.









So what I now have for ping.sls:

{% set postdata = data.get('post', {}) %}

{% if data.post.secretkey == "<secret>" %}

pingtest:
  cmd.cmd.script:
   - tgt: base-lj-3
   - fun test.ping
   - kwarg:
       user: root
       group: root

{% endif %}


This produces a "success=true" but no output.

I also tried:

{% set postdata = data.get('post', {}) %}

{% if data.post.secretkey == "<secret>" %}

pingtest:
  cmd.cmd.script:
   - tgt: base-lj-3
   - fun cmd.run
   - arg salt://srv/salt/netapi/test.sh
   - kwarg:
       user: root
       group: root

{% endif %}
