Terraform : « for_each » sur une liste dans un bloc « dynamic »

Below an example to loop on a list terraform type to create multiple dynamic terraform blocks within a terraform resource. It uses terraform content block documented here: https://www.terraform.io/docs/language/expressions/dynamic-blocks.html

• In variables.tf file:

variable "list_to_iterate" {
    description = "A list to iterate on"
    type = list(string)
    default = []
}

• In main.tf file:

resource "resource" "local_given_name" {
    dynamic "block" {
    for_each = var.list_to_iterate
        content {
        block_arg = local_given_name.value
        }
    } 
}

Ci-dessous un exemple de boucle. On utilise le bloc content de terraform, documenté ici : https://www.terraform.io/docs/language/expressions/dynamic-blocks.html

• Dans le fichier variables.tf :

variable "list_to_iterate" {
    description = "A list to iterate on"
    type = list(string)
    default = []
}

• Dans le fichier main.tf :

resource "resource" "local_given_name" {
    dynamic "block" {
    for_each = var.list_to_iterate
        content {
        block_arg = local_given_name.value
        }
    } 
}
