Inputs

Name	Description	Type	Default	Required
alarm_actions		list	n/a	yes
alarm_cpu_threshold	These vars would be used by cloudwatch.tf and should be uncommented if we decide to use them.	string	"75"	no
alarm_memory_threshold		string	"10000000"	no
allowed_cidr	A list of Security Group ID's to allow access to.	list(string)	[ "127.0.0.1/32" ]	no
allowed_security_groups	A list of Security Group ID's to allow access to.	list(string)	[]	no
apply_immediately	Specifies whether any modifications are applied immediately, or during the next maintenance window. Default is false.	bool	"false"	no
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	string	n/a	yes
redis_failover		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_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
subnets	List of VPC Subnet IDs for the cache subnet group	list(string)	n/a	yes
tags	Tags for redis nodes	map(string)	{}	no
vpc_id	VPC ID	string	n/a	yes
