Restoring ElastiCache Clustered Redis Snapshot with Terraform

Question

Is it possible to create a ElastiCache Clustered Redis cluster from a snapshot using Terraform?

I don't see a Terraform option similar to the create-replication-group --node-group-configuration cli option.

Error:

Error creating Elasticache Replication Group: InvalidParameterCombination: Slots must be provided when restoring from snapshot ARNs with cluster mode enabled 

Terraform:

resource "aws_elasticache_replication_group" "test-cluster" { replication_group_id = "test-cluster" replication_group_description = "test cluster" node_type = "cache.r3.xlarge" parameter_group_name = "default.redis3.2.cluster.on" port = 6379 automatic_failover_enabled = true subnet_group_name = "${var.subnet_group_name}" security_group_ids = ["${var.security_group_id}"] cluster_mode { replicas_per_node_group = 3 num_node_groups = 3 } snapshot_arns = ["${var.snapshot_arns}"] }

Just got an answer from AWS , its not yet possible with terraform , you need to use sdk or cli or console to do that as this feature was added in last2016. https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Replication.CreatingReplGroup.NoExistingCluster.Cluster.html#Replication.CreatingReplGroup.NoExistingCluster.Cluster.API
