Overview

An API client for PCS. To construct a client, you need to configure a :region and :credentials.

client = Aws::PCS::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

For details on configuring region and credentials see the developer guide.

See #initialize for a full list of supported configuration options.

  A list of plugins to apply to the client. Each plugin is either a class name or an instance of a plugin class.

• :credentials (required, Aws::CredentialProvider) —

  Your AWS credentials used for authentication. This can be any class that includes and implements Aws::CredentialProvider, or instance of any one of the following classes:

  • Aws::Credentials - Used for configuring static, non-refreshing credentials.

Instance Method Details

#create_cluster(params = {}) ⇒ Types::CreateClusterResponse

Creates a cluster in your account. PCS creates the cluster controller in a service-owned account. The cluster controller communicates with the cluster resources in your account. The subnets and security groups for the cluster must already exist before you use this API action.

It takes time for PCS to create the cluster. The cluster is in a Creating state until it is ready to use. There can only be 1 cluster in a Creating state per Amazon Web Services Region per Amazon Web Services account. CreateCluster fails with a ServiceQuotaExceededException if there is already a cluster in a Creating state.

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :cluster_name (required, String) —

  A name to identify the cluster. Example: MyCluster

• :scheduler (required, Types::SchedulerRequest) —

  The cluster management and job scheduling software associated with the cluster.

• :size (required, String) —

  A value that determines the maximum number of compute nodes in the cluster and the maximum number of jobs (active and queued).

  • SMALL: 32 compute nodes and 256 jobs

  • MEDIUM: 512 compute nodes and 8192 jobs

  • LARGE: 2048 compute nodes and 16,384 jobs

• :networking (required, Types::NetworkingRequest) —

  The networking configuration used to set up the cluster's control plane.

• :slurm_configuration (Types::ClusterSlurmConfigurationRequest) —

  Additional options related to the Slurm scheduler.

• :client_token (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.

  A suitable default value is auto-generated. You should normally not need to pass this option.**

• :tags (Hash<String,String>) —

  1 or more tags added to the resource. Each tag consists of a tag key and tag value. The tag value is optional and can be an empty string.

Returns:

• (Types::CreateClusterResponse) —

  Returns a response object which responds to the following methods:

  • #cluster => Types::Cluster

end

#create_compute_node_group(params = {}) ⇒ Types::CreateComputeNodeGroupResponse

Creates a managed set of compute nodes. You associate a compute node group with a cluster through 1 or more PCS queues or as part of the login fleet. A compute node group includes the definition of the compute properties and lifecycle management. PCS uses the information you provide to this API action to launch compute nodes in your account. You can only specify subnets in the same Amazon VPC as your cluster. You receive billing charges for the compute nodes that PCS launches in your account. You must already have a launch template before you call this API. For more information, see Launch an instance from a launch template in the Amazon Elastic Compute Cloud User Guide for Linux Instances.

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :cluster_identifier (required, String) —

  The name or ID of the cluster to create a compute node group in.

• :compute_node_group_name (required, String) —

  A name to identify the cluster. Example: MyCluster

• :ami_id (String) —

  The ID of the Amazon Machine Image (AMI) that PCS uses to launch compute nodes (Amazon EC2 instances). If you don't provide this value, PCS uses the AMI ID specified in the custom launch template.

• :subnet_ids (required, Array<String>) —

  The list of subnet IDs where the compute node group launches instances. Subnets must be in the same VPC as the cluster.

• :purchase_option (String) —

  Specifies how EC2 instances are purchased on your behalf. PCS supports On-Demand Instances, Spot Instances, Interruptible Capacity Reservations, On-Demand Capacity Reservations, 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. For more information about PCS support for interruptible capacity reservations, see Using I-ODCRs with PCS in the PCS User Guide. Choose On-Demand if you plan to use an On-Demand Capacity Reservation (ODCR). For more information, see Using ODCRs with PCS. If you don't provide this option, it defaults to On-Demand.

• :custom_launch_template (required, Types::CustomLaunchTemplate) —

  An Amazon EC2 launch template PCS uses to launch compute nodes.

• :iam_instance_profile_arn (required, 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.

• :scaling_configuration (required, Types::ScalingConfigurationRequest) —

  Specifies the boundaries of the compute node group auto scaling.

• :instance_configs (required, Array<Types::InstanceConfig>) —

  A list of EC2 instance configurations that PCS can provision in the compute node group.

  Additional options related to the Slurm scheduler.

• :node_lifecycle_actions (Types::NodeLifecycleActionsRequest) —

  The lifecycle actions to run on compute nodes in the compute node group. Use lifecycle actions to run custom scripts at defined stages of a compute node's lifecycle, such as when a compute node finishes bootstrapping or becomes ready to accept jobs.

• :client_token (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.

  A suitable default value is auto-generated. You should normally not need to pass this option.**

• :tags (Hash<String,String>) —

  1 or more tags added to the resource. Each tag consists of a tag key and tag value. The tag value is optional and can be an empty string.

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :cluster_identifier (required, String) —

  The name or ID of the cluster to update.

• :client_token (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.

  A suitable default value is auto-generated. You should normally not need to pass this option.**

• :slurm_configuration (Types::UpdateClusterSlurmConfigurationRequest) —

  Additional options related to the Slurm scheduler.

• :scheduler (Types::UpdateSchedulerRequest) —

  The scheduler configuration to update for the cluster. Use this to update the scheduler version. For more information, see Updating the scheduler version on a cluster in the PCS User Guide.

Returns:

• (Types::UpdateClusterResponse) —

  Returns a response object which responds to the following methods:

  • #cluster => Types::Cluster

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :cluster_identifier (required, String) —

  The name or ID of the cluster of the compute node group.

• :compute_node_group_identifier (required, String) —

  The name or ID of the compute node group.

• :ami_id (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.

• :subnet_ids (Array<String>) —

  The list of subnet IDs where the compute node group provisions instances. The subnets must be in the same VPC as the cluster.

• :custom_launch_template (Types::CustomLaunchTemplate) —

  An Amazon EC2 launch template PCS uses to launch compute nodes.

• :purchase_option (String) —

  Specifies how EC2 instances are purchased on your behalf. PCS supports On-Demand Instances, Spot Instances, Interruptible Capacity Reservations, On-Demand Capacity Reservations, 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. For more information about PCS support for interruptible capacity reservations, see Using I-ODCRs with PCS in the PCS User Guide. Choose On-Demand if you plan to use an On-Demand Capacity Reservation (ODCR). For more information, see Using ODCRs with PCS. If you don't provide this option, it defaults to On-Demand.

• :spot_options (Types::SpotOptions) —

  Additional configuration when you specify SPOT as the purchaseOption for the CreateComputeNodeGroup API action.

• :scaling_configuration (Types::ScalingConfigurationRequest) —

  Specifies the boundaries of the compute node group auto scaling.

• :iam_instance_profile_arn (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.

• :slurm_configuration (Types::UpdateComputeNodeGroupSlurmConfigurationRequest) —

  Additional options related to the Slurm scheduler.

• :node_lifecycle_actions (Types::UpdateNodeLifecycleActionsRequest) —

  The lifecycle actions to run on compute nodes in the compute node group. Use lifecycle actions to run custom scripts at defined stages of a compute node's lifecycle, such as when a compute node finishes bootstrapping or becomes ready to accept jobs.

• :client_token (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.

  A suitable default value is auto-generated. You should normally not need to pass this option.**

Returns:

• (Types::UpdateComputeNodeGroupResponse) —

  Returns a response object which responds to the following methods:

  • #compute_node_group => Types::ComputeNodeGroup
