project     = "Unknown"   environment = "Unknown" }

Variables

• vpc_id - ID of VPC meant to house the cache
• project - Name of the project making use of the cluster (default: Unknown)
• environment - Name of environment the cluster is targeted for (default: Unknown)
• cache_identifier - Name used as ElastiCache cluster ID
• automaticfailoverenabled - Flag to determine if automatic failover should be enabled
• desired_clusters - Number of cache clusters in replication group
• instance_type - Instance type for cache instance (default: cache.t2.micro)
• engine_version - Cache engine version (default: 3.2.4)
• parameter_group - Cache parameter group name (default: redis3.2)
• subnet_group - Cache subnet group name
• maintenance_window - Time window to reserve for maintenance
• notificationtopicarn - ARN to notify when cache events occur
• alarmcputhreshold - CPU alarm threshold as a percentage (default: 75)
• alarmmemorythreshold - Free memory alarm threshold in bytes (default: 10000000)
• alarm_actions - ARN to be notified via CloudWatch when alarm thresholds are triggered

Outputs

• id - The replication group ID
• cachesecuritygroup_id - Security group ID of the cache cluster
• port - Port of replication group leader
• endpoint - Public DNS name of replication group leader
