# Azure Redis Cache

[![Changelog](https://img.shields.io/badge/changelog-release-green.svg)](CHANGELOG.md) [![Notice](https://img.shields.io/badge/notice-copyright-blue.svg)](NOTICE) [![Apache V2 License](https://img.shields.io/badge/license-Apache%20V2-orange.svg)](LICENSE) [![OpenTofu Registry](https://img.shields.io/badge/opentofu-registry-yellow.svg)](https://search.opentofu.org/module/claranet/redis/azurerm/)



This Terraform module creates a [Redis Cache](https://docs.microsoft.com/en-us/azure/azure-cache-for-redis/cache-overview) instance along with

[firewall rules](https://docs.microsoft.com/en-us/azure/azure-cache-for-redis/cache-configure#firewall).

No logging is available from this resource.



The default configuration is an highly available [cluster of 3 shards](https://docs.microsoft.com/en-us/azure/azure-cache-for-redis/cache-how-to-premium-clustering)

and [data persistence enabled](https://docs.microsoft.com/en-us/azure/azure-cache-for-redis/cache-how-to-premium-persistence)

on the [Premium tier](https://docs.microsoft.com/en-us/azure/azure-cache-for-redis/cache-premium-tier-intro).

## Contributing



If you want to contribute to this repository, feel free to use our [pre-commit](https://pre-commit.com/) git hook configuration

which will help you automatically update and format some files for you by enforcing our Terraform code module best-practices.

## 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).



⚠️ Since modules version v8.0.0, we do not maintain/check anymore the compatibility with

[Hashicorp Terraform](https://github.com/hashicorp/terraform/). Instead, we recommend to use [OpenTofu](https://github.com/opentofu/opentofu/).



```hcl

module "redis" {

  source  = "claranet/redis/azurerm"

  version = "x.x.x"



  client_name    = var.client_name

  environment    = var.environment

  location       = module.azure_region.location

  location_short = module.azure_region.location_short

  stack          = var.stack



  resource_group_name = module.rg.name



  allowed_cidrs = ["1.2.3.4/32", "5.6.7.8/16"]



  logs_destinations_ids = [

    module.logs.storage_account_id,

    module.logs.id

  ]



  extra_tags = {

    foo = "bar"

  }

}
