Grains and Pillars

Sample Pillar formatting

susemanager:
  activation_key: 1-Dev-SLES-11-SP3-x86_64-key
  roles:
    - linux-dev
    - mybox-acme

AFAIK:
  key: value
  key:
    - list item
    - list item


If you want to provide a list to a grain from the command line

salt 'demobox' grains.setval roles [site1,webserver]

demobox:
    ----------
    roles:
        - site1
        - webserver

To add value to grain that already exists as list
salt 'demobox' grains.append roles site2

demobox:
    ----------
    roles:
        - site1
        - webserver
        - site2


Single value to grain
salt 'demobox' grains.setval environment dev
demobox:
    ----------
    environment:
        dev
