 Azure Image Builder uses Hashicorp Packer to create images. Packer outputs all log entries to a file called **customization.log**. By default this file is located in a resource group that Azure Image Builder created automatically with the naming convention `IT_<ResourceGroupName>_<TemplateName>_<GUID>`. You can override this naming by specifying your own name in the template creation phase.

 ## Can't progress from the source image tab in the Azure portal
 
 When you create a custom image template in the Azure portal, you might not be able to progress from the **Source image** tab if you select the **Azure Compute Gallery** as the **Source type**. A red `X` appears next to the tab name. As a workaround, select **Previous** to return to the **Basics** tab, then select **Next** to return to the **Source image** tab. You should now be able to progress to the next tab and a green check mark appears next to the tab name.

+## Authorization error occurred during Azure Container Groups operation

+Custom image templates requires the `Microsoft.ContainerInstance` resource provider registered on your subscription due to the dependency on Azure Image Builder. If you receive the error `The client '<GUID>' with object id '<GUID>' does not have authorization to perform action 'Microsoft.ContainerInstance/register/action' over scope '/subscriptions/<subscription ID>' or the scope is invalid`, you need to register the `Microsoft.ContainerInstance` resource provider on your subscription. Once you register the resource provider, try the action again. For information on how you can check their registration status and how to register them if needed, see [Azure resource providers and types](../azure-resource-manager/management/resource-providers-and-types.md).
