Hi there -
Variables defined inside the ruby trigger are limited to that triggers
scope, and aren't made
available outside the Ruby block. There are probably some work arounds if
you need some value
that the Ruby trigger has if a different provisioner needs it, but a new
Ruby variables' scope is still
limited to that Ruby block.
Thanks!
