How to use cmd_yaml in external pillar

[Luis Pugoy]

I'm trying to figure out how to use external pillars in SaltStack. I've added the following lines to /etc/salt/master:

ext_pillar:  

  - cmd_yaml: cat /srv/mysql.sls

The file /srv/mysql.sls has the following:

mysql:

  root_pw: password

Now I'm trying to figure out how to integrate this in /srv/pillar/top.sls, but during my research I haven't come across any source that shows how. I saw this for git_pillar but it doesn't give me much. Do I need to add

base:

  '*':

    - foo

to /srv/mysql.sls as well?

your pillar is exposed to all minions.

it's accessible into sls files with this jinja variable.

    {{ pillar['mysql']['root_pw'] }}

Hi Xavier,

I see. There's no way to target external pillars?

External pillars have access to the grains for the minions, and need to do their own processing on those grains to make sure they return the right pillar data for the right minions (top.sls is not used for external pillars). cmd_yaml is more of an example, and is not meant for production use.  (It can't target minions, because it doesn't have the processing required, as it's not templated through jinja or anything)

Hi Colton,

I see, thanks for the explanation. It's better if this information is available directly in the docs though. I'd be willing to update it but I don't know how.

A clarification to the docs would be most welcome! You can find the
docs inline in the source code.
