Terraform Cloud

• On local machine can debug with remotestate.tf file.

  • remotestate.tf

    terraform {
      backend "remote" {
        hostname     = "app.terraform.io"
        organization = "MyOrg"
        workspaces {
    
          name = "<workspace-name-in-tf-cloud>"
        }
      }
    }

Use RBAC for Azure blob, not storage keys

• Add  storage_use_azuread = true  to provider block e.g.

  # Configure the Microsoft Azure Provider
  provider "azurerm" {
    features {}
    # storage_use_azuread  
    # - This enables RBAC instead of access keys
    # - requires that the TFC SPN has Storage roles: Storage Blob Data Owner, Storage Blob Data Contributor.
    # - Files & Tables do not supported authentication with Azure AD.
    storage_use_azuread  = true # This enables RBAC instead of access keys
    # use_oidc             = true # If you want to use OpenID Connect
  }
