Parameters

-AuthToken <String>
Reserved parameter. The password used to access a password protected server.This parameter is valid only if:
  • The parameter TransitEncryptionEnabled was set to true when the cluster was created.
  • The line requirepass was added to the database configuration file.
Password constraints:
  • Must be only printable ASCII characters.
  • Must be at least 16 characters and no more than 128 characters in length.
  • Cannot contain any of the following characters: '/', '"', or '@'.
For more information, see AUTH password at http://redis.io/commands/AUTH.

-CacheNodeType <String>
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.

    • Current generation: T2 node types:cache.t2.micro, cache.t2.small, cache.t2.mediumM3 node types:cache.m3.medium, cache.m3.large, cache.m3.xlarge, cache.m3.2xlargeM4 node types:cache.m4.large, cache.m4.xlarge, cache.m4.2xlarge, cache.m4.4xlarge, cache.m4.10xlarge
    • Previous generation: (not recommended)T1 node types:cache.t1.microM1 node types:cache.m1.small, cache.m1.medium, cache.m1.large, cache.m1.xlarge
  • Compute optimized:
    • Previous generation: (not recommended)C1 node types:cache.c1.xlarge
  • Memory optimized:
    • Current generation: R3 node types:cache.r3.large, cache.r3.xlarge, cache.r3.2xlarge, cache.r3.4xlarge, cache.r3.8xlarge
    • Previous generation: (not recommended)M2 node types:cache.m2.xlarge, cache.m2.2xlarge, cache.m2.4xlarge
Notes:
  • All T2 instances are created in an Amazon Virtual Private Cloud (Amazon VPC).
  • Redis (cluster mode disabled): Redis backup/restore is not supported on T1 and T2 instances.
  • Redis (cluster mode enabled): Backup/restore is not supported on T1 instances.
  • Redis Append-only files (AOF) functionality is not supported for T1 or T2 instances.

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? False
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? False
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>

Required? False
Position? Named
Accept pipeline input? False
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? False

Inputs

You can pipe a String object to this cmdlet for the CacheClusterId parameter.

Outputs

This cmdlet returns a CacheCluster object. The service call response (type Amazon.ElastiCache.Model.CreateCacheClusterResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.
