How do I create a Container Registry on Azure with a resource?

Question

My terraform script is giving error like below;

Error: Error creating Container Registry "containerRegistry1" (Resource Group "aks-cluster"): containerregistry.RegistriesClient#Create: Failure sending request: StatusCode=0 -- Original Error: autorest/azure: Service returned an error. Status=<nil> Code="AlreadyInUse" Message="The registry DNS name containerregistry1.azurecr.io is already in use. You can check if the name is already claimed using following API: https://docs.microsoft.com/en-us/rest/api/containerregistry/registries/checknameavailability"

on terra.tf line 106, in resource "azurerm_container_registry" "acr": 106: resource "azurerm_container_registry" "acr" {

Whole script is below; I'm beginner at Terraform and tried different combinations but didn't worked. Not sure what can be the problem, is it possible to help?

How do I create a Container Registry on Azure with a resource?

Answer 1

From your error message, it appears like you are using a non-unique ACR name in the below pasted terraform resource declaration:

resource "azurerm_container_registry" "acr" {
**name                     = "containerRegistry1"**
resource_group_name      = azurerm_resource_group.rg.name
location                 = azurerm_resource_group.rg.location
sku                      = "Premium"
admin_enabled            = false
georeplication_locations = ["West Europe"]
}

Azure CLI has az acr check-name to ensure that ACR name is globally unique.

Answer 2

I think your issue is because your acr name is already globally taken. Not within your subscription, but GLOBALLY.

This is because ACR need a url to be accessed, and the url needs to be unique. That means some other Azure account has taken that name.
