Salt states example

# Two inconsistent and unclear ways of defining a state:

pkg.installed:
  - name: mypackage
  
apache2:
  pkg
    - installed
  service:
    - running
    - enable: True
    - require:
        pkg: mypackage
        pkg: apache2
  
# Clear way of defining a state, which allows the developer to read
# the state and understand what's happening from the name. This also
# makes it clear what's occuring when the states are run:

Ensure mypackage is installed:
  pkg.installed:
    - name: mypackage

Ensure apache installed:
  pkg.installed:
    - name: apache2

Ensure apache running:
  service.running:
    - name: apache2
    - enable: True
    - require:
        pkg: apache2
        pkg: mypackage
