Salt: Properties for pillar data?

Question

I would like to have properties (computed attributes) for data from saltstack pillars:

We structure our systems like this:

systems:
  - customer: foo 
    project: bar
    stage: p
    ...
  - customer: foo
    project: bar
    stage: q
    ...

I would like to compute a variable "system.name" like this: "{customer}_{project}_{stage}".

From the above example I would get these two computes values:

• system.name = "foo_bar_p"
• system.name = "foo_bar_q"

I would be able to access system.name just like system.customer or system.project.

How to get this done?

Answer 1

I don't think you can define properties like you'd like.

However, you can compute this value inside your state file or your template with jinja commands. For example:

{% for system in salt['pillar.get']('systems', []) %}
  {% do system.update({'name': system.customer + '_' + system.project + '_' + system.stage}) %}
test_state_for_{{ system.name }}:
  test.configurable_test_state:
    - result: False
    - comment: {{ system }}
{% endfor %}

In this example, the system dict is updated (merged) with the name computed value: system.customer + '_' + system.project + '_' + system.stage.
