        # Azure SQL

[![Changelog](https://img.shields.io/badge/changelog-release-green.svg)](CHANGELOG.md) [![Notice](https://img.shields.io/badge/notice-copyright-yellow.svg)](NOTICE) [![Apache V2 License](https://img.shields.io/badge/license-Apache%20V2-orange.svg)](LICENSE) [![TF Registry](https://img.shields.io/badge/terraform-registry-blue.svg)](https://registry.terraform.io/modules/claranet/db-sql/azurerm/)

This Terraform module creates an [Azure SQL Server](https://docs.microsoft.com/en-us/azure/sql-database/sql-database-servers)

and associated databases in an optional [SQL Elastic Pool](https://docs.microsoft.com/en-us/azure/sql-database/sql-database-elastic-pool)

with [DTU purchasing model](https://docs.microsoft.com/en-us/azure/sql-database/sql-database-service-tiers-dtu) or [vCore purchasing model](https://docs.microsoft.com/en-us/azure/azure-sql/database/resource-limits-vcore-elastic-pools)

only along with [Firewall rules](https://docs.microsoft.com/en-us/azure/sql-database/sql-database-firewall-configure)

and [Diagnostic settings](https://docs.microsoft.com/en-us/azure/sql-database/sql-database-metrics-diag-logging)

enabled.

## Usage

This module is optimized to work with the [Claranet terraform-wrapper](https://github.com/claranet/terraform-wrapper) tool

which set some terraform variables in the environment needed by this module.

More details about variables set by the `terraform-wrapper` available in the [documentation](https://github.com/claranet/terraform-wrapper#environment).
