You’re going to have to move the attribute declaration _into_ the apply rule:
apply Service "clusterx" {
vars.elb["x"] = [ "xx.ap-northeast-1.compute.amazonaws.com" ,
"xy.ap-northeast-1.compute.amazonaws.com" ]
....
if (!vars.elb["x"] { log("Array not defined") }
...
}
Otherwise your assignment would create a global variable „vars“ – which is not
associated with any service and therefore has no effect.
This seems like a good opportunity to mention

Ah, got it! This works. Thanks so much for the clarification.
Now I'm running into a new challenge. I would like to construct an
array of hostnames and then reference this array inside a service
object, as follows:
vars.elb["x"] = [ "xx.ap-northeast-1.compute.amazonaws.com" ,
"xy.ap-northeast-1.compute.amazonaws.com" ]
apply Service "clusterx" {
....
if (!vars.elb["x"] { log("Array not defined") }
...
}
The log statement shows me that this array is not defined in the
service definition. What am I doing wrong?
