Cluster
Provides an ElastiCache Cluster resource, which manages a Memcached cluster, a single-node Redis instance, or a read replica in a Redis (Cluster Mode Enabled) replication group. For more information, refer to the AWS document What is Amazon ElastiCache?. For working with Redis (Cluster Mode Enabled) replication groups, see the aws.elasticache.ReplicationGroup
resource.
Note: When you change an attribute, such as
num_cache_nodes
, by default it is applied in the next maintenance window. Because of this, this provider may report a difference in its planning phase because the actual modification has not yet taken place. You can use theapply_immediately
flag to instruct the service to apply the change immediately. Usingapply_immediately
can result in a brief downtime as the server reboots. See the "Changes take effect" section of the "Details" column in the AWS Documentation on Engine specific parameters for ElastiCache for Memcached or ElastiCache for Valkey and Redis OSS for more information. Note: Any attribute changes that re-create the resource will be applied immediately, regardless of the value ofapply_immediately
.

Import
Using pulumi import
, import ElastiCache Clusters using the cluster_id
. For example:
$ pulumi import aws:elasticache/cluster:Cluster my_cluster my_cluster
Properties
Whether any database modifications are applied immediately, or during the next maintenance window. Default is false
. See Amazon ElastiCache Documentation for more information.
Specifies whether minor version engine upgrades will be applied automatically to the underlying Cache Cluster instances during the maintenance window. Only supported for engine type "redis"
and if the engine version is 6 or higher. Defaults to true
.
Availability Zone for the cache cluster. If you want to create cache nodes in multi-az, use preferred_availability_zones
instead. Default: System chosen Availability Zone. Changing this value will re-create the resource.
Whether the nodes in this Memcached node group are created in a single Availability Zone or created across multiple Availability Zones in the cluster's region. Valid values for this parameter are single-az
or cross-az
, default is single-az
. If you want to choose cross-az
, num_cache_nodes
must be greater than 1
.
List of node objects including id
, address
, port
and availability_zone
.
(Memcached only) DNS name of the cache cluster without the port appended.
(Memcached only) Configuration endpoint to allow host discovery.
Version number of the cache engine to be used. If not set, defaults to the latest version. See Describe Cache Engine Versions in the AWS Documentation for supported versions. When engine
is redis
and the version is 7 or higher, the major and minor version should be set, e.g., 7.2
. When the version is 6, the major and minor version can be set, e.g., 6.2
, or the minor version can be unspecified which will use the latest version at creation time, e.g., 6.x
. Otherwise, specify the full version desired, e.g., 5.0.6
. The actual engine version used is returned in the attribute engine_version_actual
, see Attribute Reference below. Cannot be provided with replication_group_id.
Because ElastiCache pulls the latest minor or patch for a version, this attribute returns the running version of the cache engine.
Name of your final cluster snapshot. If omitted, no final snapshot will be made.
The IP version to advertise in the discovery protocol. Valid values are ipv4
or ipv6
.
Specifies the destination and format of Redis SLOWLOG or Redis Engine Log. See the documentation on Amazon ElastiCache. See Log Delivery Configuration below for more details.
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. Example: sun:05:00-sun:09:00
.
The IP versions for cache cluster connections. IPv6 is supported with Redis engine 6.2
onword or Memcached version 1.6.6
for all Nitro system instances. Valid values are ipv4
, ipv6
or dual_stack
.
The instance class used. See AWS documentation for information on supported node types for Valkey or Redis OSS and guidance on selecting node types for Valkey or Redis OSS. See AWS documentation for information on supported node types for Memcached and guidance on selecting node types for Memcached. For Memcached, changing this value will re-create the resource.
ARN of an SNS topic to send ElastiCache notifications to. Example: arn:aws:sns:us-east-1:012345678999:my_sns_topic
.
The initial number of cache nodes that the cache cluster will have. For Redis, this value must be 1. For Memcached, this value must be between 1 and 40. If this number is reduced on subsequent runs, the highest numbered nodes will be removed.
Specify the outpost mode that will apply to the cache cluster creation. Valid values are "single-outpost"
and "cross-outpost"
, however AWS currently only supports "single-outpost"
mode.
The name of the parameter group to associate with this cache cluster. The following arguments are optional:
List of the Availability Zones in which cache nodes are created. If you are creating your cluster in an Amazon VPC you can only locate nodes in Availability Zones that are associated with the subnets in the selected subnet group. The number of Availability Zones listed must equal the value of num_cache_nodes
. If you want all the nodes in the same Availability Zone, use availability_zone
instead, or repeat the Availability Zone multiple times in the list. Default: System chosen Availability Zones. Detecting drift of existing node availability zone is not currently supported.

is not supported on cache.t1.micro cache nodes
Daily time range (in UTC) during which ElastiCache will begin taking a daily snapshot of your cache cluster. Example: 05:00-09:00
