# This is the reason why we can't separate nodes and load balancer creation into different modules.

# https://github.com/hashicorp/terraform/issues/10857

# In short: the list of instances coming from the nodes module is a generated variable
|
|
# and it should be the input for the load-balancer generation. However when attaching the instances
|
|
# to the load-balancer, aws_lb_target_group_attachment.count cannot be a generated value.
