A Terraform module to create a Redis ElastiCache cluster

A terraform module providing a Redis ElastiCache cluster in AWS.

This module

• Creates Redis ElastiCache clusters
• Creates, manages, and exports a security group

Usage

module "redis" {
  source         = "github.com/terraform-community-modules/tf_aws_elasticache_redis?ref=v1.3.0"
  env            = "${var.env}"
  name           = "thtest"
  redis_clusters = "2"
  redis_failover = "true"
  subnets        = "${module.vpc.database_subnets}"
  vpc_id         = "${module.vpc.vpc_id}"
}

Usage with redis_parameters

variable "redis_parameters" {
  description = "additional parameters"
  default = [{
    name  = "min-slaves-max-lag"
    value = "5"
  },{
    name  = "min-slaves-to-write"
    value = "1"
  },{
    name  = "databases"
    value = "32"
  }]
}

module "redis" {
  source           = "github.com/Flaconi/terraform-aws-elasticache-redis?ref=v0.2.0"
  ...
  redis_parameters = "${var.redis_parameters}"
  ...
}

Inputs

Name	Description	Type	Default	Required
env	env to deploy into, should typically dev/staging/prod	string	n/a	yes
name	Name for the Redis replication group i.e. UserObject	string	n/a	yes
redis_clusters	Number of Redis cache clusters (nodes) to create	number	n/a	yes
subnets	List of VPC Subnet IDs for the cache subnet group	list(string)	n/a	yes
vpc_id	VPC ID	string	n/a	yes
allowed_cidr	A list of Security Group ID's to allow access to.	list(string)	[ "127.0.0.1/32" ]	no
apply_immediately	Specifies whether any modifications are applied immediately, or during the next maintenance window. Default is false.	bool	false	no
multi_az_enabled	Specifies whether to enable Multi-AZ Support for the replication group	bool	false	no
redis_failover	Specifies whether cluster should perform automatic fail-over	bool	false	no
redis_maintenance_window	Specifies the weekly time range for when maintenance on the cache cluster is performed. The format is ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance window is a 60 minute period	string	"fri:08:00-fri:09:00"	no
redis_node_type	Instance type to use for creating the Redis cache clusters	string	"cache.t2.micro"	no

redis_port	Which port redis will be listening on	number	6379	no
redis_snapshot_retention_limit	The number of days for which ElastiCache will retain automatic cache cluster snapshots before deleting them. For example, if you set SnapshotRetentionLimit to 5, then a snapshot that was taken today will be retained for 5 days before being deleted. If the value of SnapshotRetentionLimit is set to zero (0), backups are turned off. Please note that setting a snapshot_retention_limit is not supported on cache.t1.micro or cache.t2.* cache nodes	number	0	no
redis_snapshot_window	The daily time range (in UTC) during which ElastiCache will begin taking a daily snapshot of your cache cluster. The minimum snapshot window is a 60 minute period	string	"06:30-07:30"	no
redis_version	Redis version to use, defaults to 3.2.10	string	"3.2.10"	no
security_groups	A list of Security Group ID's to allow access to.	list(string)	[]	no
tags	Tags for redis nodes	map(string)	{}	no
