IF Statement
I want an module in terraform which is able to execute two different codes.
One with a image from a Publisher and other with a custom image.
Codes above show how to specify both operations in the same module:
module "virtualmachine" {
source = "git@github.com:accountname/git.git///path?ref=xxxxxxxx"
vm_name = "virtualmachine"
location = "East US 2"
vm_image_reference = "no"
image_publisher = "MicrosoftSQLServer"
image_offer = "SQL2016SP1-WS2016"
image_sku = "Enterprise"
image_version = "latest"
vm_size = "Standard_DS11_v2"
vm_disk_type = "Premium_LRS"
vm_data_disks = ["1023"]
}
module "virtualmachine" {
source = "git@github.com:accountname/git.git///path?ref=xxxxxxxx"
vm_name = "virtualmachine"
location = "East US 2"
vm_image_reference = "yes"
vm_image = "/subscriptions/xxxxxxxxxxxxx/resourceGroups/Images/providers/Microsoft.Compute/images/centos_720201230"
vm_size = "Standard_DS11_v2"
vm_disk_type = "Premium_LRS"
vm_data_disks = ["1023"]
}
resource "azurerm_virtual_machine" "image" {
count = "${format("%.1s", var.vm_image_reference) == "y" ? 1 : 0}"
.
.
.
}
resource "azurerm_virtual_machine" "market" {
count = "${format("%.1s", var.vm_image_reference) == "n" ? 1 : 0}"
.
.
.
}
Example with Null Resource
resource "null_resource" "zero" {
count = "${signum(format("%.1s", var.yes) == "y" ? 1 : 0) * signum(format("%.1s", var.no) == "y" ? 1 : 0)}"
provisioner "local-exec" {
command = "echo zero}"
}
}
resource "null_resource" "um" {
count = "${signum(format("%.1s", var.yes) == "y" ? 1 : 0) * signum(format("%.1s", var.yes) == "y" ? 1 : 0)}"
provisioner "local-exec" {
command = "echo um}"
}
}
variable "yes" {
default = "yes"
}
variable "no" {
default = "no"
}
AND
| foo | bar | result |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 1 | 1 |
count = "${var.foo * var.bar}"
OR
| foo | bar | result |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 1 | 1 |
count = "${signum(var.foo + var.bar)}"
