Feature Request: cdk construct for parallel cluster

[snemir2]

Now that parallel cluster supports CloudFormation custom resource, was wondering if you can officially support cdk deployment of parallel clusters. As a quick poc, deploying the custom resource and then paralell cluster works in principal (python cdk below)

class CustomResourceProvider(Stack):
    ServiceToken=None
    def __init__(self, scope: Construct, construct_id: str, env , params, **kwargs) -> None:
        super().__init__(scope, construct_id, **kwargs)

        #cloudfomation for custom resource provider 
        PC_CF_CRP="https://" + env.region +"-aws-parallelcluster.s3." + env.region + ".amazonaws.com/parallelcluster/" + params['PC_VERSION'] + "/templates/custom_resource/cluster.yaml"

        #deploy cfn_stack for custom resource provider
        cfn_stack=cdk.CfnStack(self, "ParallelClusterCustomResourceProvider",
                               template_url=PC_CF_CRP)

        output=cdk.CfnOutput( self, "ServiceToken", 
                   value=cfn_stack.get_att("Outputs.ServiceToken").to_string())

        self.ServiceToken=cfn_stack.get_att("Outputs.ServiceToken").to_string()

class ParallelCluster(Stack):

    def __init__(self, scope: Construct, construct_id: str, env , params, ServiceToken, **kwargs) -> None:
        super().__init__(scope, construct_id, **kwargs)

        # now lets provision a cluster thrugh the deployed custom resource provider

        ###this needs to be parameterized by environment
        CLUSTER_CONFIG = yaml.safe_load(open("deployment_v2/config-file.yaml", 'r'))

        print ("ServiceToken: " + ServiceToken)     
        CustomResource(self, "PclusterClusterSERGEY",
            resource_type="Custom::PclusterCluster",
            service_token=ServiceToken, 
            properties={
                'ClusterName': 'SERGEY',
                'ClusterConfiguration': CLUSTER_CONFIG

            }

        )

Hello! Thank you for the feature request! Could you elaborate a bit more to help me to understand the request? Do you mean adding official support for ParallelCluster deployment with cdk by introducing ParallelCluster construct in aws-construct-library: https://docs.aws.amazon.com/cdk/api/v2/docs/aws-construct-library.html

Thanks

The goal is to easily provision clusters with CDK with the rest of the infra.

[chenwany]

Thanks, I tracked this into our backlog

Hi, I am also keen to get this feature so I can convert my current convoluted solution to a more elegant one

[tcutts]

I'd like to see ParallelCluster formally supported by CDK too - wondering whether the feature request really needs to be with CDK rather than ParallelCluster though?

[pradoz]

I would find this enhancement useful as well. Ideally, the configuration file would be abstracted into parameters to allow cluster management directly from CDK

@chenwany Where can one view where this landed in the backlog?
