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](/sdk-for-ruby/v3/developer-guide/setup-config.html).

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

#initialize(options) ⇒ Client

Returns a new instance of Client.

Parameters:

  • options (Hash)

Options Hash (options):

  • :plugins (Array<Seahorse::Client::Plugin>) — default: []] —

    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.

    • ‘Aws::SharedCredentials` - Used for loading static credentials from a shared file, such as `~/.aws/config`.

    • ‘Aws::AssumeRoleCredentials` - Used when you need to assume a role.

    • ‘Aws::AssumeRoleWebIdentityCredentials` - Used when you need to assume a role after providing credentials via the web.

    • ‘Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an access token generated from `aws login`.

    • ‘Aws::ProcessCredentials` - Used for loading credentials from a process that outputs to stdout.

    • ‘Aws::InstanceProfileCredentials` - Used for loading credentials from an EC2 IMDS on an EC2 instance.

    • ‘Aws::ECSCredentials` - Used for loading credentials from instances running in ECS.

    • ‘Aws::CognitoIdentityCredentials` - Used for loading credentials from the Cognito Identity service.

    When ‘:credentials` are not configured directly, the following locations will be searched for credentials:

    • ‘Aws.config`

    • The ‘:access_key_id`, `:secret_access_key`, `:session_token`, and `:account_id` options.

    • ‘ENV`, `ENV`, `ENV`, and `ENV`.

    • ‘~/.aws/credentials`

    • ‘~/.aws/config`

    • EC2/ECS IMDS instance profile - When used by default, the timeouts are very aggressive. Construct and pass an instance of ‘Aws::InstanceProfileCredentials` or `Aws::ECSCredentials` to enable retries and extended timeouts. Instance profile credential fetching can be disabled by setting `ENV` to `true`.

  • :region (required, String) —

    The AWS region to connect to. The configured ‘:region` is used to determine the service `:endpoint`. When not passed, a default `:region` is searched for in the following locations:

  • :access_key_id (String)
  • :account_id (String)
  • :active_endpoint_cache (Boolean) — default: false —

    When set to ‘true`, a thread polling for endpoints will be running in the background every 60 secs (default). Defaults to `false`.

  • :adaptive_retry_wait_to_fill (Boolean) — default: true —

    Used only in ‘adaptive` retry mode. When true, the request will sleep until there is sufficent client side capacity to retry the request. When false, the request will raise a `RetryCapacityNotAvailableError` and will not retry instead of sleeping.

  • :auth_scheme_preference (Array<String>) —

    A list of preferred authentication schemes to use when making a request. Supported values are: ‘sigv4`, `sigv4a`, `httpBearerAuth`, and `noAuth`. When set using `ENV` or in shared config as `auth_scheme_preference`, the value should be a comma-separated list.

The request parameters hash must be formatted exactly as the API expects.This option is useful when you want to ensure the highest level of performance by avoiding overhead of walking request parameters and response data structures.

  • :stub_responses (Boolean) — default: false —

    Causes the client to return stubbed responses. By default fake responses are generated and returned. You can specify the response data to return or errors to raise by calling ClientStubs#stub_responses. See ClientStubs for more information.

    ** Please note ** When response stubbing is enabled, no HTTP requests are made, and retries are disabled.

  • :telemetry_provider (Aws::Telemetry::TelemetryProviderBase) — default: Aws::Telemetry::NoOpTelemetryProvider —

    Allows you to provide a telemetry provider, which is used to emit telemetry data. By default, uses ‘NoOpTelemetryProvider` which will not record or emit any telemetry data. The SDK supports the following telemetry providers:

    • OpenTelemetry (OTel) - To use the OTel provider, install and require the

    ‘opentelemetry-sdk` gem and then, pass in an instance of a `Aws::Telemetry::OTelProvider` for telemetry provider.

  • :token_provider (Aws::TokenProvider) —

    Your Bearer token used for authentication. This can be any class that includes and implements ‘Aws::TokenProvider`, or instance of any one of the following classes:

    • ‘Aws::StaticTokenProvider` - Used for configuring static, non-refreshing tokens.

    • ‘Aws::SSOTokenProvider` - Used for loading tokens from AWS SSO using an access token generated from `aws login`.

    When ‘:token_provider` is not configured directly, the `Aws::TokenProviderChain` will be used to search for tokens configured for your profile in shared configuration files.

  • :use_dualstack_endpoint (Boolean) —

    When set to ‘true`, dualstack enabled endpoints (with `.aws` TLD) will be used if available.

  • :use_fips_endpoint (Boolean) —

  • :validate_params (Boolean) — default: true —

    When ‘true`, request parameters are validated before sending the request.

  • :endpoint_provider (Aws::PCS::EndpointProvider) —

    The endpoint provider used to resolve endpoints. Any object that responds to ‘#resolve_endpoint(parameters)` where `parameters` is a Struct similar to `Aws::PCS::EndpointParameters`.

  • :http_continue_timeout (Float) — default: 1 —

    The number of seconds to wait for a 100-continue response before sending the request body. This option has no effect unless the request has “Expect” header set to “100-continue”. Defaults to ‘nil` which disables this behaviour. This value can safely be set per request on the session.

  • :http_idle_timeout (Float) — default: 5 —

    The number of seconds a connection is allowed to sit idle before it is considered stale. Stale connections are closed and removed from the pool before making a request.

    A proxy to send requests through. Formatted like ‘proxy.com:123’.

  • :http_read_timeout (Float) — default: 60 —

    The default number of seconds to wait for response data. This value can safely be set per-request on the session.

  • :http_wire_trace (Boolean) — default: false —

    When ‘true`, HTTP debug output will be sent to the `:logger`.

  • :on_chunk_received (Proc) —

    When a Proc object is provided, it will be used as callback when each chunk of the response body is received. It provides three arguments: the chunk, the number of bytes received, and the total number of bytes in the response (or nil if the server did not send a ‘content-length`).

  • :on_chunk_sent (Proc) —

    When a Proc object is provided, it will be used as callback when each chunk of the request body is sent. It provides three arguments: the chunk, the number of bytes read from the body, and the total number of bytes in the body.

  • :raise_response_errors (Boolean) — default: true —

    When ‘true`, response errors are raised.

  • :ssl_ca_bundle (String) —

    Full path to the SSL certificate authority bundle file that should be used when verifying peer certificates. If you do not pass ‘:ssl_ca_bundle` or `:ssl_ca_directory` the the system default will be used if available.

#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.

<note markdown=“1”> 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:

#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*.

    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*.

    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:

    The value of ‘nextToken` is a unique pagination token for each page of results returned. If `nextToken` is returned, there are more results available. Make the call again using the returned token to retrieve the next page. Keep all other arguments unchanged. Each pagination token expires after 24 hours. Using an expired pagination token returns an `HTTP 400 InvalidToken` error.

  • :max_results (Integer) —

    The maximum number of results that are returned per call. You can use ‘nextToken` to obtain further pages of results. The default is 10 results, and the maximum allowed page size is 100 results. A value of 0 uses the default.

Returns:
