DESCRIPTION

Adds an AWS::ElastiCache::ReplicationGroup resource to the template. The AWS::ElastiCache::ReplicationGroup resource creates an Amazon ElastiCache Redis replication group. A replication group is a collection of cache clusters, where one of the clusters is a primary read-write cluster and the others are read-only replicas.

PARAMETERS

-LogicalId

The logical ID must be alphanumeric (A-Za-z0-9) and unique within the template. Use the logical name to reference the resource in other parts of the template. For example, if you want to map an Amazon Elastic Block Store volume to an Amazon EC2 instance, you reference the logical IDs to associate the block stores with the instance.

Type: String
Parameter Sets: (All)
Aliases:

Required: True
Position: 1
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-AtRestEncryptionEnabled

A flag that enables encryption at rest when set to true. You cannot modify the value of AtRestEncryptionEnabled after the replication group is created. To enable encryption at rest on a replication group you must set AtRestEncryptionEnabled to true when you create the replication group. Required: Only available when creating a replication group in an Amazon VPC using redis version 3.2.6 or 4.x onward. Default: false

-CacheNodeType

The compute and memory capacity of the nodes in the node group shard. The following node types are supported by ElastiCache. Generally speaking, the current generation types provide more memory and computational power at lower cost when compared to their equivalent previous generation counterparts. Changing the CacheNodeType of a Memcached instance is currently not supported. If you need to scale using Memcached, we recommend forcing a replacement update by changing the LogicalResourceId of the resource.

  • General purpose:
  • Current generation: M5 node types: cache.m5.large, cache.m5.xlarge, cache.m5.2xlarge, cache.m5.4xlarge, cache.m5.12xlarge, cache.m5.24xlarge M4 node types: cache.m4.large, cache.m4.xlarge, cache.m4.2xlarge, cache.m4.4xlarge, cache.m4.10xlarge T3 node types: cache.t3.micro, cache.t3.small, cache.t3.medium T2 node types: cache.t2.micro, cache.t2.small, cache.t2.medium
  • Previous generation: not recommended T1 node types: cache.t1.micro M1 node types: cache.m1.small, cache.m1.medium, cache.m1.large, cache.m1.xlarge M3 node types: cache.m3.medium, cache.m3.large, cache.m3.xlarge, cache.m3.2xlarge
  • Compute optimized:
  • Previous generation: not recommended C1 node types: cache.c1.xlarge
  • Memory optimized:
  • Current generation: R5 node types: cache.r5.large, cache.r5.xlarge, cache.r5.2xlarge, cache.r5.4xlarge, cache.r5.12xlarge, cache.r5.24xlarge R4 node types: cache.r4.large, cache.r4.xlarge, cache.r4.2xlarge, cache.r4.4xlarge, cache.r4.8xlarge, cache.r4.16xlarge
  • Previous generation: not recommended M2 node types: cache.m2.xlarge, cache.m2.2xlarge, cache.m2.4xlarge R3 node types: cache.r3.large, cache.r3.xlarge, cache.r3.2xlarge, cache.r3.4xlarge, cache.r3.8xlarge

-CacheParameterGroupName

The 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. If you are restoring to an engine version that is different than the original, you must specify the default version of that version. For example, CacheParameterGroupName=default.redis4.0. If you are running Redis version 3.2.4 or later, only one node group shard, and want to use a default parameter group, we recommend that you specify the parameter group by name.

  • To create a Redis cluster mode disabled replication group, use CacheParameterGroupName=default.redis3.2.
  • To create a Redis cluster mode enabled replication group, use CacheParameterGroupName=default.redis3.2.cluster.on.

-DeletionPolicy

With the DeletionPolicy attribute you can preserve or (in some cases) backup a resource when its stack is deleted. You specify a DeletionPolicy attribute for each resource that you want to control. If a resource has no DeletionPolicy attribute, AWS CloudFormation deletes the resource by default.

To keep a resource when its stack is deleted, specify Retain for that resource. You can use retain for any resource. For example, you can retain a nested stack, S3 bucket, or EC2 instance so that you can continue to use or modify those resources after you delete their stacks.

You must use one of the following options: “Delete”,”Retain”,”Snapshot”

Type: String
Parameter Sets: (All)
Aliases:

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-UpdateReplacePolicy

Use the UpdateReplacePolicy attribute to retain or (in some cases) backup the existing physical instance of a resource when it is replaced during a stack update operation.

When you initiate a stack update, AWS CloudFormation updates resources based on differences between what you submit and the stack’s current template and parameters. If you update a resource property that requires that the resource be replaced, AWS CloudFormation recreates the resource during the update. Recreating the resource generates a new physical ID. AWS CloudFormation creates the replacement resource first, and then changes references from other dependent resources to point to the replacement resource. By default, AWS CloudFormation then deletes the old resource. Using the UpdateReplacePolicy, you can specify that AWS CloudFormation retain or (in some cases) create a snapshot of the old resource.

For resources that support snapshots, such as AWS::EC2::Volume, specify Snapshot to have AWS CloudFormation create a snapshot before deleting the old resource instance.

You can apply the UpdateReplacePolicy attribute to any resource. UpdateReplacePolicy is only executed if you update a resource property whose update behavior is specified as Replacement, thereby causing AWS CloudFormation to replace the old resource with a new one with a new physical ID. For example, if you update the Engine property of an AWS::RDS::DBInstance resource type, AWS CloudFormation creates a new resource and replaces the current DB instance resource with the new one. The UpdateReplacePolicy attribute would then dictate whether AWS CloudFormation deleted, retained, or created a snapshot of the old DB instance. The update behavior for each property of a resource is specified in the reference topic for that resource in the AWS Resource and Property Types Reference. For more information on resource update behavior, see Update Behaviors of Stack Resources.

The UpdateReplacePolicy attribute applies to stack updates you perform directly, as well as stack updates performed using change sets.

Note Resources that are retained continue to exist and continue to incur applicable charges until you delete those resources. Snapshots that are created with this policy continue to exist and continue to incur applicable charges until you delete those snapshots. UpdateReplacePolicy retains the old physical resource or snapshot, but removes it from AWS CloudFormation’s scope.

UpdateReplacePolicy differs from the DeletionPolicy attribute in that it only applies to resources replaced during stack updates. Use DeletionPolicy for resources deleted when a stack is deleted, or when the resource definition itself is deleted from the template as part of a stack update.
