Terraform module which creates Redis ElastiCache resources on AWS.

Description

Provision ElastiCache_Replication_Group and Parameter Group.

This module provides recommended settings:

  • Enable Multi-AZ
  • Enable automatic failover
  • Enable at-rest encryption
  • Enable in-transit encryption
  • Enable automated backups

Usage

Minimal

module "elasticache_redis" {
  source                = "git::https://github.com/tmknom/terraform-aws-elasticache-redis.git?ref=tags/2.0.0"
  name                  = "example"
  number_cache_clusters = 2
  node_type             = "cache.m3.medium"

  subnet_ids         = var.subnet_ids
  vpc_id             = var.vpc_id
  source_cidr_blocks = var.source_cidr_blocks
}

Complete
