Get private ip from redshitf cluster

[SebasSx]

I tried to get the private ip of the nodes of a redshift cluster using this:

const cluster = new aws.redshift.Cluster(`${RedshiftprojectName}-cluster`, {
        clusterIdentifier: `${RedshiftprojectName}-cluster`,
        clusterType: "multi-node",
        databaseName: userCredentials.getSecret('database'),
        masterPassword: userCredentials.getSecret('userpassword'),
        masterUsername: userCredentials.getSecret('username'),
        nodeType: "ds2.xlarge",
        numberOfNodes: 2,
        publiclyAccessible: false,
        skipFinalSnapshot: true,
        enhancedVpcRouting: true,
        clusterSubnetGroupName: params.RSSubnetGroup.redshiftSubnetGroup.name,
        vpcSecurityGroupIds: [securityGroup.id],
        iamRoles:[dmAccessForEndpoint.arn,redshiftAccessRole.arn],
    });

    return {
        my_cluster: cluster.clusterNodes[0].privateIpAddress
    }

But I got this error: Cannot read property '0' of undefined

Can someone help me?

I created a simplified full pulumi program to create a redshift cluster, and wasn't able to reproduce this:

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
import * as awsx from "@pulumi/awsx";

const vpc = new awsx.ec2.Vpc(`redshift-vpc`, {
    cidrBlock: "172.16.0.0/24",
    tags: {
        Name: `redshift-vpc`,
        Owner: "lbriggs",
        owner: "lbriggs",
    }
});

const subnetGroup = new aws.redshift.SubnetGroup("example", {
    subnetIds: vpc.privateSubnetIds,
    tags: {
        Owner: "lbriggs",
        owner: "lbriggs",
    },
});

const securityGroup = new aws.ec2.SecurityGroup("lambda", {
    ingress: [
        { protocol: "-1", fromPort: 0, toPort: 0, cidrBlocks: [ "172.16.0.0/24" ] },
    ],
    egress: [
        { protocol: "-1", fromPort: 0, toPort: 0, cidrBlocks: ["0.0.0.0/0"] },
    ],
    vpcId: vpc.id,
})

const cluster = new aws.redshift.Cluster('example-cluster', {
    clusterIdentifier: 'example-cluster',
    clusterType: "multi-node",
    masterPassword: 'correct-Horse-battery-stab1e',
    masterUsername: 'administrator',
    nodeType: "ds2.xlarge",
    numberOfNodes: 2,
    publiclyAccessible: false,
    skipFinalSnapshot: true,
    enhancedVpcRouting: true,
    clusterSubnetGroupName: subnetGroup.name,
    vpcSecurityGroupIds: [securityGroup.id],
});

export const nodes = cluster.clusterNodes

Some things you might try:

• check if the redshift cluster provisioned correctly in the AWS console.
• check the version of the AWS provider you're using

[SebasSx]

I tried this way but I got an empty object. Also the cluster is provisioned correctly in the AWS console.

Hi @SebasSx. Which object was empty? When I run the same program @jaxxstorm has quoted above, I also get a result:

$ pulumi up
...

Outputs:
    nodes: [
        [0]: {
            nodeRole        : "LEADER"
            privateIpAddress: "172.16.0.252"
        }
        [1]: {
            nodeRole        : "COMPUTE-0"
            privateIpAddress: "172.16.0.243"
        }
        [2]: {
            nodeRole        : "COMPUTE-1"
            privateIpAddress: "172.16.0.226"
        }
    ]
