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!
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 = "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.
