## We are pulling default values from configmaps if they exist already
## Using conditional_set_fact allows us to set the value of a variable based on
##  the value of another one, if it is already defined. Else we don't set the
##  left hand side (it stays undefined as well).

## conditional_set_fact allows us to specify a fact source, so first we try to
##  set variables in the logging-elasticsearch & logging-elasticsearch-ops configmaps
##  afterwards we set the value of the variable based on the value in the inventory
##  but fall back to using the value from a configmap as a default. If neither is set
##  then the variable remains undefined and the role default will be used.
