terraform-aws-redis-lambda

A Terraform module that represents an AWS ElastiCache Redis cluster and a Lambda function that connects to it. See example usage below.

Usage

1. Download demo-lambda-redis.zip into the folder you are terraforming from.

2. Run terraform, here is a sample plan

provider "aws" {
 version = "~> 1.8.0"
 region = "us-east-1"
}

module "elasticache_redis" {
 source = "github.com/udaysharma/terraform-aws-redis-lambda?ref=v1.0"

 cluster_id            = "Sandbox-redis"
 engine_version        = "2.8.24"
 instance_type         = "cache.t2.micro"
 maintenance_window    = "sun:05:00-sun:06:00"
 vpc_id                = "vpc-xxxxxxxx"
 private_subnet_ids    = "subnet-xxxxxxxx,subnet-yyyyyyyy"
 private_subnet_cidrs  = "x.x.x.x/x,y.y.y.y/y"
 parameter_group_name  = "default.redis2.8"
 tag_name              = "Sandbox-redis"
 tag_contact-email     = "example@domain.com"
 attach_vpc_config     = true
}

Variables

• cluster_id - ID of the cluster
• vpc_id - ID of VPC meant to house the cache
• private_subnet_ids - Comma delimited list of private subnet IDs
• engine_version - Cache engine version (default: 2.8.24)
• instance_type - Instance type for cache instance (default: cache.t2.micro)
• maintenance_window - 60 minute time window to reserve for maintenance (default: sun:05:00-sun:06:00)
• parameter_group_name- Name of the parameter group to associate with this cache cluster (default: default.redis2.8)
• tag_name - Name tag for the Elasticache Redis cluster
• tag_contact-email - Email tag for the Elasticache Redis cluster

Outputs

• hostname - Public DNS name of cache node
• port - Port of cache instance
• endpoint - Public DNS name and port separated by a :
• cache_security_group_id - Security group ID of the cache cluster
• iam-role-arn - ARN for IAM role created for Lambda function
