Goal of this repo is to develop Databricks DR automation based on best practice suggested by various DB articles.

DevOps Automation workflow for Multi-region DR

This Terraform configuration deploys:

• A Databricks workspace (Premium tier)
• A VNet with:
  • Public and private subnets
  • Subnet delegation for Databricks
  • NSG (Network Security Group) attachments
• VNet injection for secure Databricks deployment
• Support for Active/Passive DR setup across regions

• Terraform >= 1.3
• Azure CLI (az login)
• Sufficient Azure permissions to create resources

az account set --subscription "<your-subscription-name-or-id>" 

az group create \ --name databricks-demo \ --location eastus 

az storage account create \ --name bcrterraformstatefiles \ --resource-group databricks-demo \ --location eastus \ --sku Standard_LRS \ --kind StorageV2 \ --allow-blob-public-access false az storage account keys list \ --account-name bcrterraformstatefiles \ --resource-group databricks-demo \ --query "[0].value" \ -o tsv az storage container create \ --name tfstate \ --account-name bcrterraformstatefiles \ --account-key <YOUR_STORAGE_ACCOUNT_KEY> 

# Step into the environment folder cd infra/prod/eastus # Initialize the Terraform project terraform init # Preview what will be created terraform plan -var-file="terraform.tfvars" # Apply the infrastructure terraform apply -var-file="terraform.tfvars"

** Wait for 5 minutes before login to the workspace **

export DATABRICKS_HOST="https://<Databricks-instance-id>.cloud.databricks.com" export DATABRICKS_TOKEN="<YOUR-PAT>" cd /apps/dev terraform init terraform plan -var-file="terraform.tfvars" terraform apply --auto-approve -var-file="terraform.tfvars" 

terraform destroy -var-file="terraform.tfvars"

After deployment, you'll get:

• databricks_host — URL to access your Databricks workspace

• Adjust the terraform.tfvars to match region and resource group for each deployment.
• Use additional folders like westus for DR/secondary regions.
