ReplicationGroup

class ReplicationGroup : KotlinCustomResource

Provides an ElastiCache Replication Group resource. For working with a Memcached cluster or a single-node Redis instance (Cluster Mode Disabled), see the aws.elasticache.Cluster resource.

Note: When you change an attribute, such as engine_version, by default the ElastiCache API applies it 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 the apply_immediately flag to instruct the service to apply the change immediately. Using apply_immediately can result in a brief downtime as servers reboots. See the AWS Documentation on Modifying an ElastiCache Cache Cluster for more information. Note: Any attribute changes that re-create the resource will be applied immediately, regardless of the value of apply_immediately. Note: Be aware of the terminology collision around "cluster" for aws.elasticache.ReplicationGroup. For example, it is possible to create a "Cluster Mode Disabled Redis Cluster". With "Cluster Mode Enabled", the data will be stored in shards (called "node groups"). See Redis Cluster Configuration for a diagram of the differences. To enable cluster mode, use a parameter group that has cluster mode enabled. The default parameter groups provided by AWS end with ".cluster.on", for example default.redis6.x.cluster.on.

Example Usage

Redis OSS/Valkey Cluster Mode Disabled

To create a single shard primary with single read replica:

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
const example = new aws.elasticache.ReplicationGroup("example", {
    automaticFailoverEnabled: true,
    preferredCacheClusterAzs: [

        "us-west-2b",
    ],
    replicationGroupId: "tf-rep-group-1",
    description: "example description",
    nodeType: "cache.m4.large",
    numCacheClusters: 2,
    parameterGroupName: "default.redis3.2",
    port: 6379,
});

You have two options for adjusting the number of replicas:

Adjusting num_cache_clusters directly. This will attempt to automatically add or remove replicas, but provides no granular control (e.g., preferred availability zone, cache cluster ID) for the added or removed replicas. This also currently expects cache cluster IDs in the form of replication_group_id-00#.
Otherwise for fine grained control of the underlying cache clusters, they can be added or removed with the aws.elasticache.Cluster resource and its replication_group_id attribute. In this situation, you will need to utilize ignoreChanges to prevent perpetual differences with the number_cache_cluster attribute.

Note: We currently do not support passing a primary_cluster_id in order to create the Replication Group. Note: Automatic Failover is unavailable for Redis versions earlier than 2.8.6, and unavailable on T1 node types. For T2 node types, it is only available on Redis version 3.2.4 or later with cluster mode enabled. See the High Availability Using Replication Groups guide for full details on using Replication Groups.

Creating a secondary replication group for a global replication group

A Global Replication Group can have up to two secondary Replication Groups in different regions. These are added to an existing Global Replication Group.

When adding a new auth_token to a previously passwordless replication group, using the ROTATE update strategy will result in support for both the new token and passwordless authentication. To immediately require authorization when adding the initial token, use the SET strategy instead. See the Authenticating with the Redis AUTH command guide for additional details.

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.

engineVersionActual

val engineVersionActual: Output<String>

Because ElastiCache pulls the latest minor or patch for a version, this attribute returns the running version of the cache engine.

finalSnapshotIdentifier

val finalSnapshotIdentifier: Output<String>?

globalReplicationGroupId

val globalReplicationGroupId: Output<String>

The ID of the global replication group to which this replication group should belong. If this parameter is specified, the replication group is added to the specified global replication group as a secondary replication group; otherwise, the replication group is not part of any global replication group. If global_replication_group_id is set, the num_node_groups parameter cannot be set.

ipDiscovery

val ipDiscovery: Output<String>

The IP version to advertise in the discovery protocol. Valid values are ipv4 or ipv6.

kmsKeyId

memberClusters

val memberClusters: Output<List<String>>

Identifiers of all the nodes that are part of this replication group.

multiAzEnabled

val multiAzEnabled: Output<Boolean>?

Specifies whether to enable Multi-AZ Support for the replication group. If true, automatic_failover_enabled must also be enabled. Defaults to false.

networkType

val networkType: Output<String>

The IP versions for cache cluster connections. Valid values are ipv4, ipv6 or dual_stack.

nodeType

val nodeType: Output<String>

Instance class to be used. See AWS documentation for information on supported node types and guidance on selecting node types. Required unless global_replication_group_id is set. Cannot be set if global_replication_group_id is set.

notificationTopicArn

val notificationTopicArn: Output<String>?

ARN of an SNS topic to send ElastiCache notifications to. Example: arn:aws:sns:us-east-1:012345678999:my_sns_topic

numCacheClusters

val numCacheClusters: Output<Int>

Number of cache clusters (primary and replicas) this replication group will have. If automatic_failover_enabled or multi_az_enabled are true, must be at least 2. Updates will occur before other modifications. Conflicts with num_node_groups and replicas_per_node_group. Defaults to 1.

numNodeGroups

val numNodeGroups: Output<Int>

Number of node groups (shards) for this Redis replication group. Changing this number will trigger a resizing operation before other settings modifications. Conflicts with num_cache_clusters.

parameterGroupName

val parameterGroupName: Output<String>

Name of the parameter group to associate with this replication group. If this argument is omitted, the default cache parameter group for the specified engine is used. To enable "cluster mode", i.e., data sharding, use a parameter group that has the parameter cluster-enabled set to true.

port

val port: Output<Int>?

Port number on which each of the cache nodes will accept connections. For Memcache the default is 11211, and for Redis the default port is 6379.

preferredCacheClusterAzs

val preferredCacheClusterAzs: Output<List<String>>?

List of EC2 availability zones in which the replication group's cache clusters will be created. The order of the availability zones in the list is considered. The first item in the list will be the primary node. Ignored when updating.

List of ARNs that identify Redis RDB snapshot files stored in Amazon S3. The names object names cannot contain any commas.

snapshotName
