是否可以将资源创建与循环(使用计数)相结合,并根据地图的值有条件地跳过某些资源?
我知道我们可以分开做这些事情:
为了说明我可以说我有一张地图列表:
variable "resources" {
type = "list"
default = [
{
name = "kafka"
createStorage = true
},
{
name = "elastic"
createStorage = false
},
{
name = "galera"
createStorage = true
}
]
}
我可以遍历上面的列表并使用资源中的'count'创建三个资源:
resource "azurerm_storage_account" "test" {
name = "test${var.environment}${lookup(var.resources[count.index], "name")}sa"
location = "${var.location}"
resource_group_name = "test-${var.environment}-vnet-rg"
account_tier = "Standard"
account_replication_type = "GRS"
enable_blob_encryption = true
count = "${length(var.resources)}"
}
但是,我还想跳过创建createStorage = false
的资源。因此,在上面的示例中,我想创建两个存储帐户,但跳过“弹性”存储帐户。
这可能吗?

在terraform 0.12.x中,您可以过滤掉createStorage=true
所在的列表,并将其用于计数表达式
variable "resources" {
type = "list"
default = [
{
name = "kafka"
createStorage = true
},
{
name = "elastic"
createStorage = false
},
{
name = "galera"
createStorage = true
}
]
}
locals {
resources_to_create = [
for resource in var.resources :
resource
if resource.createStorage == true
]
}
resource "azurerm_storage_account" "test" {
count = length(local.resources_to_create)
name = "test${var.environment}${lookup(local.resources_to_create[count.index], "name")}sa"
location = var.location
resource_group_name = "test-${var.environment}-vnet-rg"
account_tier = "Standard"
account_replication_type = "GRS"
enable_blob_encryption = true
}
