Executing a Salt state run can potentially change many aspects of a system and it may be desirable to first see what a state run is going to change before applying the run.
Salt has a test interface to report on exactly what will be changed, this interface can be invoked on any of the major state run functions:
salt '*' state.highstate test=True
salt '*' state.sls test=True
salt '*' state.single test=True
The test run is mandated by adding the test=True
option to the states. The
return information will show states that will be applied in yellow and the
result is reported as None
.
If the value test
is set to True
in the minion configuration file then
states will default to being executed in test mode. If this value is set then
states can still be run by calling test=False:
salt '*' state.highstate test=False
salt '*' state.sls test=False
salt '*' state.single test=False
