+
+# Data Source: azurerm_container_registry
+
+Use this data source to access information about a Container Registry
+
+## Example Usage
+
+```hcl
+data "azurerm_container_registry" "test" {
+  name                = "testacr"
+  resource_group_name = "test"
+}
+
+output "login_server" {
+  value = "${data.azurerm_container_registry.test.login_server}"
+}
+```
+
+## Argument Reference
+
+* `name` - (Required) The name of the Container Registry.

+
+* `location` - The Azure Region in which this Container Registry exists.
+
+* `admin_enabled` - Is the Administrator account enabled for this Container Registry.
+
+* `sku` - The SKU of this Container Registry, such as `Basic`.
