Chapter 5: Terraform tips and tricks

usage:

resource "blablabla" "blablabla_name" {
count = 3
name  = "bla${count.index}"
}

result: 3 elements ([0],[1],[2])

with length():

variable "bla_names" {
  type    = list(string)
  default = ["bla_green","bla_yellow","bla_red"] 
resource "blablabla" "blablabla_name" {
  count = length(var.bla_names)
  name  = bla_names[count.index]
}

each element is assigned to their index in state, deletes o modifications implies «move» all elements after that.

only usable for resources, no inline blocks
