ParallelComputingService / Client / create_cluster

create_cluster#

ParallelComputingService.Client.create_cluster(**kwargs)#

Creates a cluster in your account. Amazon Web Services 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

It takes time for Amazon Web Services 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.

  Subnets can’t be in Outposts, Wavelength or an Amazon Web Services Local Zone.
  
  Note
  Amazon Web Services PCS currently supports only 1 subnet in this list.
  - (string) –
- securityGroupIds (list) –
  
  A list of security group IDs associated with the Elastic Network Interface (ENI) created in subnets.

  The time before an idle node is scaled down.

  Additional Slurm-specific configuration that directly maps to Slurm settings.
  - (dict) –
    
    Additional settings that directly map to Slurm settings.
    - parameterName (string) – [REQUIRED]
      
      Amazon Web Services PCS supports configuration of the following Slurm parameters:
      - For clusters
        
        Prolog
        
        Epilog
        
        SelectTypeParameters
      - For compute node groups
        
        Weight
        
        RealMemory
    - parameterValue (string) – [REQUIRED]
      
      The values for the configured Slurm settings.
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.

This field is autopopulated if not provided.
tags (dict) –
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.
- (string) –
  - (string) –

Return type:
