Terraform module to provision an ElastiCache Redis Cluster
This project is part of our comprehensive "SweetOps" approach towards DevOps.
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!
Include this repository as a module in your existing terraform code:
// 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 = "general"
name = "redis"
stage = "prod"
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}"
}Review the complete example to see how to use this module.
