Recently I started studying Salt and I have been looking over the tutorials they offer.
At the moment I am reading something about Reactor System and came upon this:
{% if not data['result'] and data['id'].startswith('ink') %}
minion_remove:
wheel.key.delete:
- match: {{ data['id'] }}
What I don't understand is the purpose and role of the data keyword.What does it actually do and represent?
The reason for asking you this is because I see it to be called similar to a grain: salt['grains.get ....](...)
Is this the case of just a particular case or is this something much more important in the Saltworld
The Salt's reactor is reacting to events (see https://docs.saltstack.com/en/latest/topics/reactor/index.html). They have a tag (a usually hierarchical name), and data (known in other systems a payload).
Using the data and tag keywords you can reference them in your states.
