For more information on Azure Key Vault, see the Azure Key Vault documentation. One of either block or page. If you wish to manage the content outside of Terraform you can use terraform taint to force a recreation of this resource - alternatively you can look to set this content via Terraform using the source property within the azurerm_storage_blob resource to point a local file. The State is an essential building block of every Terraform project. Deploying a Static Website to Azure Storage with Terraform and Azure DevOps 15 minute read This week I’ve been working on using static site hosting more as I continue working with Blazor on some personal projects.. My goal is to deploy a static site to Azure, specifically into an Azure Storage account to host my site, complete with Terraform for my infrastructure as code. This pattern prevents concurrent state operations, which can cause corruption. Starting Terraform locally To keep track of your Infrastructure with Terraform, you will have to let Terraform store your tfstate file in a safe place.

Create an environment variable named ARM_ACCESS_KEY with the value of the Azure Storage access key. State allows Terraform to know what Azure resources to add, update, or delete. Terraform state is used to reconcile deployed resources with Terraform configurations. The storage account name, container name and storage account access key are all values from the Azure storage account service. When you store the Terraform state file in an Azure Storage Account, you get the benefits of RBAC (role-based accesscontrol) and data encryption. Terraform supports a large array of backends, including Azure, GCS, S3, etcd and many many more. This blob will point to a key where there is no file yet.
