adding two different groups of ec2 instances to aws

My question is if I have something like this in aws_elb block for dataAnode ec2 instance group [this works as expected ]

instances = ["${aws_instance.dataAnode.*.id}"]

but now I have dataBnode group of instances.

can I do this ?

instances = ["${aws_instance.dataAnode.*.id}", "${aws_instance.dataBnode.*.id}"]

basically how do I have one list from these two different types of aws_isntance groups?

I have not tried using concat menthod, but if that is the only way, I can go for it... any suggestions would be appreciated

I use Terraform v0.11

You can use concat:

instances = "${concat(aws_instance.dataAnode.*.id, aws_instance.dataBnode.*.id)}"
