Membuat klaster

Saat Anda menjalankan contoh skrip berikut, dengan input yang diberikan disimpan di lingkungan Anda, Anda membuat cluster. Konfigurasi cluster dibuat sebagai tipe data Python berdasarkandokumentasi konfigurasi cluster.

import os
import pprint
import pcluster.lib as pc
pp = pprint.PrettyPrinter()

HEAD_NODE_SUBNET = os.environ["HEAD_NODE_SUBNET"]
COMPUTE_NODE_SUBNET = os.environ["HEAD_NODE_SUBNET"]
KEY_NAME = os.environ["KEY_NAME"]
CONFIG = {'Image': {'Os': 'alinux2'},
          'HeadNode': {'InstanceType': 't2.large',
                       'Networking': {'SubnetId': HEAD_NODE_SUBNET},
                       'Ssh': {'KeyName': KEY_NAME}},

          'Scheduling': {'Scheduler': 'slurm',
                         'SlurmQueues':
                         [{'Name': 'queue0',
                           'ComputeResources':
                           [{'Name': 'queue0-i0', 'InstanceType': 't2.micro',
                             'MinCount': 0, 'MaxCount': 10}],
                           'Networking': {'SubnetIds': [COMPUTE_NODE_SUBNET]}}]}}


pp.pprint(pc.create_cluster(cluster_name="mycluster", cluster_configuration=CONFIG))

Output:

{'cluster': {'cloudformationStackArn': 'arn:aws:cloudformation:us-east-2:123456789012:stack/mycluster/00000000-aaaa-1111-999-000000000000',
             'cloudformationStackStatus': 'CREATE_IN_PROGRESS',
             'clusterName': 'mycluster',
             'clusterStatus': 'CREATE_IN_PROGRESS',
             'region': 'us-east-2',
             'scheduler': {'type': 'slurm'},
             'version': '3.7.0'}}
