搭CreateCluster配 AWS 開發套件或 CLI 使用

下列程式碼範例會示範如何使用CreateCluster。

CLI

AWS CLI

以最小的 ParametersThis 範例建立叢集會建立具有最少組參數的叢集。默認情況下，輸出為 JSON 格式。命令：

aws redshift create-cluster --node-type dw.hs1.xlarge --number-of-nodes 2 --master-username adminuser --master-user-password TopSecret1 --cluster-identifier mycluster

結果：

{
   "Cluster": {
      "NodeType": "dw.hs1.xlarge",
      "ClusterVersion": "1.0",
      "PubliclyAccessible": "true",
      "MasterUsername": "adminuser",
      "ClusterParameterGroups": [
         {
            "ParameterApplyStatus": "in-sync",
            "ParameterGroupName": "default.redshift-1.0"
         } ],
      "ClusterSecurityGroups": [
         {
            "Status": "active",
            "ClusterSecurityGroupName": "default"
         } ],
      "AllowVersionUpgrade": true,
      "VpcSecurityGroups": \[],
      "PreferredMaintenanceWindow": "sat:03:30-sat:04:00",
      "AutomatedSnapshotRetentionPeriod": 1,
      "ClusterStatus": "creating",
      "ClusterIdentifier": "mycluster",
      "DBName": "dev",
      "NumberOfNodes": 2,
      "PendingModifiedValues": {
         "MasterUserPassword": "\****"
      }
   },
   "ResponseMetadata": {
      "RequestId": "7cf4bcfc-64dd-11e2-bea9-49e0ce183f07"
   }
}

建立 叢集

    public static void createCluster(RedshiftClient redshiftClient, String clusterId, String masterUsername,
                                     String masterUserPassword) {
        try {
            CreateClusterRequest clusterRequest = CreateClusterRequest.builder()
                .clusterIdentifier(clusterId)
                .masterUsername(masterUsername)
                .masterUserPassword(masterUserPassword)
                .nodeType("ra3.4xlarge")
                .publiclyAccessible(true)
                .numberOfNodes(2)
                .build();

            CreateClusterResponse clusterResponse = redshiftClient.createCluster(clusterRequest);
            System.out.println("Created cluster " + clusterResponse.cluster().clusterIdentifier());

        } catch (RedshiftException e) {

            System.err.println(e.getMessage());
            System.exit(1);

建立用戶端。

import { RedshiftClient } from "@aws-sdk/client-redshift";
// Set the AWS Region.
const REGION = "REGION";
//Set the Redshift Service Object
const redshiftClient = new RedshiftClient({ region: REGION });
export { redshiftClient };

建立 叢集

// Import required AWS SDK clients and commands for Node.js
import { CreateClusterCommand } from "@aws-sdk/client-redshift";
import { redshiftClient } from "./libs/redshiftClient.js";

const params = {
  ClusterIdentifier: "CLUSTER_NAME", // Required
  NodeType: "NODE_TYPE", //Required
  MasterUsername: "MASTER_USER_NAME", // Required - must be lowercase
  MasterUserPassword: "MASTER_USER_PASSWORD", // Required - must contain at least one uppercase letter, and one number
  ClusterType: "CLUSTER_TYPE", // Required
  IAMRoleARN: "IAM_ROLE_ARN", // Optional - the ARN of an IAM role with permissions your cluster needs to access other AWS services on your behalf, such as Amazon S3.
  ClusterSubnetGroupName: "CLUSTER_SUBNET_GROUPNAME", //Optional - the name of a cluster subnet group to be associated with this cluster. Defaults to 'default' if not specified.
  DBName: "DATABASE_NAME", // Optional - defaults to 'dev' if not specified
  Port: "PORT_NUMBER", // Optional - defaults to '5439' if not specified
};

const run = async () => {
