![使用 Terraform 恢复 ElastiCache 集群 Redis 快照](https://linux22.com/image/717047/%E4%BD%BF%E7%94%A8%20Terraform%20%E6%81%A2%E5%A4%8D%20ElastiCache%20%E9%9B%86%E7%BE%A4%20Redis%20%E5%BF%AB%E7%85%A7.png)
是否可以使用 Terraform 从快照创建 ElastiCache Clustered Redis 集群?
我没有看到类似于create-replication-group --node-group-configuration
cli 选项的 Terraform 选项。
错误:
Error creating Elasticache Replication Group: InvalidParameterCombination: Slots must be provided when restoring from snapshot ARNs with cluster mode enabled
地形:
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}"]
}

刚刚收到来自 AWS 的答复,terraform 还无法实现,您需要使用 sdk 或 cli 或控制台来执行此操作,因为此功能是在 last2016 中添加的。 https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Replication.CreatingReplGroup.NoExistingCluster.Cluster.html#Replication.CreatingReplGroup.NoExistingCluster.Cluster.API
