locals terraform block

A local value can only be accessed in expressions within the module where it was declared.

Examples

locals {
  service_name = "forum"
  owner        = "Community Team"
}

locals {
 # Ids for multiple sets of EC2 instances, merged together
 instance_ids = concat(aws_instance.blue.*.id, aws_instance.green.*.id)
}

locals {
  # Common tags to be assigned to all resources
  common_tags = {
    Service = local.service_name
    Owner   = local.owner
  }
}
