Terraform module to provision an ElastiCache Redis Cluster


This project is part of our comprehensive "SweetOps" approach towards DevOps.

Terraform Open Source Modules

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Usage

IMPORTANT: The master branch is used in source just as an example. In your code, do not pin to master because there may be breaking changes between releases. Instead pin to the release tag (e.g. ?ref=tags/x.y.z) of one of our latest releases.

// Generate a random string for auth token, no special chars
resource "random_string" "auth_token" {
  length = 64
  special = false
}

module "example_redis" {
  source          = "git::https://github.com/cloudposse/terraform-aws-elasticache-redis.git?ref=master"
  namespace       = "eg"
  stage           = "dev"
  name            = "redis"
  zone_id         = var.route53_zone_id
  security_groups = [var.security_group_id]

  auth_token                   = random_string.auth_token.result
  vpc_id                       = var.vpc_id
  subnets                      = var.private_subnets
  maintenance_window           = "wed:03:00-wed:04:00"
  cluster_size                 = 2
  instance_type                = "cache.t2.micro"
  engine_version               = "4.0.10"
  alarm_cpu_threshold_percent  = var.cache_alarm_cpu_threshold_percent
  alarm_memory_threshold_bytes = var.cache_alarm_memory_threshold_bytes
  apply_immediately            = true
  availability_zones           = var.availability_zones
  automatic_failover           = false
}

output "auth_token" {
  value = random_string.auth_token.result
}
