locals terraform block

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

Examples

locals {
  environment  = "prod"
  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
  }
}
locals {
  name   = "example-${replace(basename(path.cwd), "_", "-")}"
  region = "eu-west-1"
  tags = {
    Owner       = "user"
    Environment = "dev"
 }
}
