Description

Updates a compute node group. You can update many of the fields related to your compute node group including the configurations for networking, compute nodes, and settings specific to your scheduler (such as Slurm).

Parameters

-AmiId <String>
The ID of the Amazon Machine Image (AMI) that PCS uses to launch instances. If not provided, PCS uses the AMI ID specified in the custom launch template.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ClientConfig <AmazonPCSConfig>
Amazon.PowerShell.Cmdlets.PCS.AmazonPCSClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ClientToken <String>
A unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Idempotency ensures that an API request completes only once. With an idempotent request, if the original request completes successfully, the subsequent retries with the same client token return the result from the original successful request and they have no additional effect. If you don't specify a client token, the CLI and SDK automatically generate 1 for you.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ClusterIdentifier <String>
The name or ID of the cluster of the compute node group.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-ComputeNodeGroupIdentifier <String>
The name or ID of the compute node group.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-CustomLaunchTemplate_Id <String>
The ID of the EC2 launch template to use to provision instances. Example: lt-xxxx
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-CustomLaunchTemplate_Version <String>
The version of the EC2 launch template to use to provision instances.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-IamInstanceProfileArn <String>
The Amazon Resource Name (ARN) of the IAM instance profile used to pass an IAM role when launching EC2 instances. The role contained in your instance profile must have the pcs:RegisterComputeNodeGroupInstance permission and the role name must start with AWSPCS or must have the path /aws-pcs/. For more information, see IAM instance profiles for PCS in the PCS User Guide.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PurchaseOption <PurchaseOption>
Specifies how EC2 instances are purchased on your behalf. PCS supports On-Demand Instances, Spot Instances, and Amazon EC2 Capacity Blocks for ML. For more information, see Amazon EC2 billing and purchasing options in the Amazon Elastic Compute Cloud User Guide. For more information about PCS support for Capacity Blocks, see Using Amazon EC2 Capacity Blocks for ML with PCS in the PCS User Guide. If you don't provide this option, it defaults to On-Demand.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ScalingConfiguration_MaxInstanceCount <Int32>
The upper bound of the number of instances allowed in the compute fleet.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ScalingConfiguration_MinInstanceCount <Int32>
The lower bound of the number of instances allowed in the compute fleet.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'ComputeNodeGroup'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.PCS.Model.UpdateComputeNodeGroupResponse). Specifying the name of a property of type Amazon.PCS.Model.UpdateComputeNodeGroupResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-SlurmConfiguration_SlurmCustomSetting <SlurmCustomSetting[]>
Additional Slurm-specific configuration that directly maps to Slurm settings. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesSlurmConfiguration_SlurmCustomSettings
-SpotOptions_AllocationStrategy <SpotAllocationStrategy>
The Amazon EC2 allocation strategy PCS uses to provision EC2 instances. PCS supports lowest price, capacity optimized, and price capacity optimized. For more information, see Use allocation strategies to determine how EC2 Fleet or Spot Fleet fulfills Spot and On-Demand capacity in the Amazon Elastic Compute Cloud User Guide. If you don't provide this option, it defaults to price capacity optimized.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-SubnetId <String[]>
The list of subnet IDs where the compute node group provisions instances. The subnets must be in the same VPC as the cluster. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.

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?True (ByPropertyName)
AliasesAK
-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?True (ByValue, ByPropertyName)
-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?True (ByPropertyName)
-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?True (ByValue, ByPropertyName)
-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.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.
