I want to attach multiple instances to target_group on the basis of dynamic value but facing some issues as the code is not computing the proper values.
Below is the code.
data "aws_instances" "instances" {
instance_tags {
role = "${lookup(var.target_groups[count.index], "trole")}"
}
filter {
name = "tag:environment"
values = ["${var.environment}"]
}
filter {
name = "tag:component"
values = ["${lookup(var.target_groups[count.index], "tcomponent")}"]
}
filter {
name = "tag:subcomponent"
values = ["${lookup(var.target_groups[count.index], "tsubcomponent")}"]
}
}
resource "aws_lb_target_group_attachment" "instance_attachment" {
target_group_arn = "${element(aws_lb_target_group.targetg.*.arn, var.target_groups_count)}
target_id = "${element(data.aws_instances.instances.ids, count.index)}"
port = "${lookup(var.target_groups[count.index], "backend_port")}"
count = "${length(data.aws_instances.instances.ids)}"
}
from input files
target_groups = "${list(map("name", "test1-80", "tcomponent", "compo1", "tsubcomponent", "subcompo1", "trole", "app", "backend_protocol", "HTTP", "backend_port", "80", "health_check_path", "/_status"), map("name", "test2-80", "tcomponent", "compo2", "tsubcomponent", "subcompo2", "trole", "app", "backend_protocol", "HTTP", "backend_port", "80", "health_check_path", "/_status"), map("name", "test3", "tcomponent", "compo3", "tsubcomponent", "subcompo3", "trole", "node", "backend_protocol", "HTTP", "backend_port", "80", "health_check_path", "/_status"))}"

Can you explain more by what you mean when you say it's not computing the proper values? Does it error? If so can you post the exact error you get? Does it work but give you the wrong result? If so can you post the result and what you expected to happen? Also it would help if you could adjust your formatting so thetarget_groupsvalue is readable (split it across multiple lines where possible).

@ydaetskcoR: thanks for your revert. basically, it is producing the wrong result. I want to attach only those instances whose tagging will match with tags of target group.
