I have a set of subnet’s how do i assign the subnets which are available automatically using terraform? Ex : [“subnet-a”,”subnet-b”,”subnet-c”, “subnet-d”]

Answer 1

Use random_shuffle:

resource "random_shuffle" "az" {
  input        = [“subnet-a”,”subnet-b”,”subnet-c”]
  result_count = 2
}

then to get the actual result:

random_shuffle.az.result
