terraform-elasticache

Terraform modules to set up redis and memcache.

redis

This creates a redis cluster with some default values and creates a security group for the cluster that allows a specific security group to access the redis cluster

Available variables:

Name	Description	Type	Default	Required
allowed_sgs	The security group that can access the redis cluster	`list(string)`	n/a	yes
at_rest_encryption_enabled	(Optional) Whether to enable encryption at rest	`bool`	`true`	no
auth_token	(Optional) The password used to access a password protected server. Can be specified only if `transit_encryption_enabled = true`	`string`	`null`	no
automatic_failover_enabled	n/a	`bool`	`false`	no
availability_zones	the list of AZs where you want your cluster to be deployed in	`list(string)`	n/a	yes
cloudwatch_logging_enabled	(Optional) Whether to enable cloudwatch logging	`bool`	`false`	no
cloudwatch_logging_retention_in_days	Retention period for the logs in CloudWatch. Default is 7d.	`number`	`7`	no
engine_version	The redis engine version	`string`	`"3.2.6"`	no
environment	How do you want to call your environment	`string`	n/a	yes
multi_az_enabled	n/a	`bool`	`false`	no
name	The name of the redis cluster	`string`	n/a	yes
node_type	The instance size of the redis cluster	`string`	n/a	yes
notification_topic_arn	(Optional) ARN of an SNS topic to send ElastiCache notifications	`string`	`null`	no
num_cache_nodes	The number of cache nodes	`number`	n/a	yes
parameter_group_name	The parameter group name	`string`	`"default.redis3.2"`	no
port	The redis port	`number`	`6379`	no
project	The project this redis cluster belongs to	`string`	n/a	yes
snapshot_arns	(Optional) A single-element string list containing an Amazon Resource Name (ARN) of a Redis RDB snapshot file stored in Amazon S3. Example: arn:aws:s3:::my_bucket/snapshot1.rdb	`list(string)`	`[]`	no
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
snapshot_window	The daily time range (in UTC) during which ElastiCache will begin taking a daily snapshot of your cache cluster. The minimum maintenance window is a 60 minute period. Example: 05:00-09:00	`string`	`"03:00-05:00"`	no
subnets	The subnets where the redis cluster is deployed	`list(string)`	n/a	yes
transit_encryption_enabled	(Optional) Whether to enable encryption in transit	`bool`	`true`	no
vpc_id	The vpc where we will put the redis cluster	`string`	n/a	yes

Output

Name	Description
configuration_endpoint_address	n/a
primary_endpoint_address	n/a
redis_sg	n/a

Example

module "redis" {
  source          = "github.com/skyscrapers/terraform-elasticache//redis"
  name            = "redis"
  project         = var.project
  environment     = terraform.workspace
  node_type       = "cache.t3.small"
  num_cache_nodes = "1"
  subnets         = module.vpc.private_db_subnets
  allowed_sgs     = [module.app.sg_id]
  vpc_id          = module.vpc.vpc_id
}

memcache

Available variables

Name	Description	Type	Default	Required
allowed_sgs	The security group that can access the memcache cluster	`list(string)`	n/a	yes
environment	How do you want to call your environment	`string`	n/a	yes
name	The name of the memcache cluster	`string`	n/a	yes
node_type	The instance size of the memcache cluster	`string`	n/a	yes
num_cache_nodes	The number of cache nodes	`number`	n/a	yes
project	The project this memcache cluster belongs to	`string`	n/a	yes
subnets	The subnets where the memcache cluster is deployed	`list(string)`	n/a	yes
vpc_id	The vpc where we will put the memcache cluster	`string`	n/a	yes
engine_version	The memcache engine version	`string`	`"1.4.5"`	no
parameter_group_name	The parameter group name	`string`	`"default.memcached1.4"`	no
port	The memcache port	`number`	`11211`	no

Output

Name	Description
memcache_endpoint	The DNS name of the memcache cluster
memcache_sg	The security group ID of the memcache cluster.
