If upgrading from an earlier version, see\n[migration notes](https://github.com/cloudposse/terraform-aws-elasticache-redis/blob/master/docs/migration-notes-0.41.0.md) for details._\n\nNote that this uses secure defaults. One of the ways this module can trip users up is with `transit_encryption_enabled`\nwhich is `true` by default. With this enabled, one does not simply `redis-cli` in without setting up an `stunnel`.\nAmazon provides [good documentation on how to connect with it enabled](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/in-transit-encryption.html#connect-tls).\nIf this is not desired behavior, set `transit_encryption_enabled=false`.\n\nThis module creates, by default, a new security group for the Elasticache Redis Cluster / Serverless Instance.\nWhen a configuration change (for example, a different security group name) cannot be applied to the security group, Terraform will\nreplace that security group with a new one with the new configuration. In order to allow Terraform to fully manage the security group, you\nshould not place any other resources in (or associate any other resources with) the security group this module\ncreates. Also, in order to keep things from breaking when this module replaces the security group, you should\nnot reference the created security group anywhere else (such as in rules in other security groups). If you\nwant to associate the cluster with a more stable security group that you can reference elsewhere, create that security group\noutside this module (perhaps with [terraform-aws-security-group](https://github.com/cloudposse/terraform-aws-security-group))\nand pass the security group ID in via `associated_security_group_ids`.\n\n**Note about `zone_id`**: Previously, `zone_id` was a string. This caused problems (see [#82](https://github.com/cloudposse/terraform-aws-elasticache-redis/issues/82)).\nNow `zone_id` should be supplied as a `list(string)`, either empty or with exactly 1 zone ID in order to avoid the problem.\n\nFor a complete example, see [examples/complete](examples/complete) or [examples/serverless](examples/serverless).\n\nFor automated tests of the complete example using [bats](https://github.com/bats-core/bats-core) and [Terratest](https://github.com/gruntwork-io/terratest) (which tests and deploys the example on AWS), see [test](test).\n\n```hcl\nprovider \"aws\" {\n  region = var.region\n}\n\nmodule \"this\" {\n  source  = \"cloudposse/label/null\"\n  # Cloud Posse recommends pinning every module to a specific version\n  # version = \"x.x.x\"\n  namespace  = var.namespace\n  stage      = var.stage\n  name       = var.name\n}\n\nmodule \"vpc\" {\n  source = \"cloudposse/vpc/aws\"\n  # Cloud Posse recommends pinning every module to a specific version\n  # version = \"x.x.x\"\n\n  cidr_block = \"172.16.0.0/16\"\n\n  context = module.this.context\n}\n\nmodule \"subnets\" {\n  source = \"cloudposse/dynamic-subnets/aws\"\n  # Cloud Posse recommends pinning every module to a specific version\n  # version = \"x.x.x\"\n\n  availability_zones   = var.availability_zones\n  vpc_id               = module.vpc.vpc_id\n  igw_id               = module.vpc.igw_id\n  cidr_block           = module.vpc.vpc_cidr_block\n  nat_gateway_enabled  = true\n  nat_instance_enabled = false\n\n  context = module.this.context\n}\n\nmodule \"redis\" {\n  source = \"cloudposse/elasticache-redis/aws\"\n  # Cloud Posse recommends pinning every module to a specific version\n  # version = \"x.x.x\"\n\n  availability_zones         = var.availability_zones\n  zone_id                    = var.zone_id\n  vpc_id                     = module.vpc.vpc_id\n  allowed_security_group_ids = [module.vpc.vpc_default_security_group_id]\n  subnets                    = module.subnets.private_subnet_ids\n  cluster_size               = var.cluster_size\n  instance_type              = var.instance_type\n  apply_immediately          = true\n  automatic_failover_enabled = false\n  engine_version             = var.engine_version\n  family                     = var.family\n  at_rest_encryption_enabled = var.at_rest_encryption_enabled\n  transit_encryption_enabled = var.transit_encryption_enabled\n\n  parameter = [\n    {\n      name  = \"notify-keyspace-events\"\n      value = \"lK\"\n    }\n  ]\n\n  context = module.this.context\n}\n```\n\n\u003e [!IMPORTANT]\n\u003e In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation\n\u003e and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version\n\u003e you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic\n\u003e approach for updating versions to avoid unexpected changes.\n\n\n\n\n\n## Examples\n\nReview the [complete example](examples/complete) or [serverless example](examples/serverless) to see how to use this module.\n\n\n\n\n\u003c!-- markdownlint-disable --\u003e\n## Makefile Targets\n```text\nAvailable targets:\n\n  help                                Help screen\n  help/all                            Display help for all targets\n  help/short                          This help short screen\n  lint                                Lint terraform code\n\n```\n\u003c!-- markdownlint-restore --\u003e\n\u003c!-- markdownlint-disable --\u003e\n## Requirements\n\n| Name | Version |\n|------|---------|\n| \u003ca name=\"requirement_terraform\"\u003e\u003c/a\u003e [terraform](#requirement\\_terraform) | \u003e= 1.3 |\n| \u003ca name=\"requirement_aws\"\u003e\u003c/a\u003e [aws](#requirement\\_aws) | \u003e= 5.47.0 |\n\n## Providers\n\n| Name | Version |\n|------|---------|\n| \u003ca name=\"provider_aws\"\u003e\u003c/a\u003e [aws](#provider\\_aws) | \u003e= 5.47.0 |\n\n## Modules\n\n| Name | Source | Version |\n|------|--------|---------|\n| \u003ca name=\"module_aws_security_group\"\u003e\u003c/a\u003e [aws\\_security\\_group](#module\\_aws\\_security\\_group) | cloudposse/security-group/aws | 2.2.0 |\n| \u003ca name=\"module_dns\"\u003e\u003c/a\u003e [dns](#module\\_dns) | cloudposse/route53-cluster-hostname/aws | 0.13.0 |\n| \u003ca name=\"module_this\"\u003e\u003c/a\u003e [this](#module\\_this) | cloudposse/label/null | 0.25.0 |\n\n## Resources\n\n| Name | Type |\n|------|------|\n| [aws_cloudwatch_metric_alarm.cache_cpu](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/cloudwatch_metric_alarm) | resource |\n| [aws_cloudwatch_metric_alarm.cache_memory](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/cloudwatch_metric_alarm) | resource |\n| [aws_elasticache_parameter_group.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/elasticache_parameter_group) | resource |\n| [aws_elasticache_replication_group.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/elasticache_replication_group) | resource |\n| [aws_elasticache_serverless_cache.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/elasticache_serverless_cache) | resource |\n| [aws_elasticache_subnet_group.default](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/elasticache_subnet_group) | resource |\n\n## Inputs\n\n| Name | Description | Type | Default | Required |\n|------|-------------|------|---------|:--------:|\n| \u003ca name=\"input_additional_security_group_rules\"\u003e\u003c/a\u003e [additional\\_security\\_group\\_rules](#input\\_additional\\_security\\_group\\_rules) | A list of Security Group rule objects to add to the created security group, in addition to the ones\u003cbr/\u003ethis module normally creates.
