Using Aws Elasticache With Cloudformation

Introduction

This guide will show you how to use AWS ElastiCache with CloudFormation in a Pulumi program. We will create an ElastiCache cluster using Pulumi’s AWS provider, which will involve setting up a VPC, subnet group, and the ElastiCache cluster itself.

Step-by-Step Explanation

Step 1: Set up the VPC

First, we need to create a VPC where our ElastiCache cluster will reside. This will include creating subnets and a subnet group.

Step 2: Create the Subnet Group

Next, we create a subnet group for the ElastiCache cluster. This subnet group will include the subnets created in the previous step.

Step 3: Create the ElastiCache Cluster

Finally, we create the ElastiCache cluster within the VPC and subnet group.

Summary

In this guide, we created an AWS ElastiCache cluster using Pulumi and CloudFormation. We set up a VPC, created a subnet group, and then created the ElastiCache cluster. This setup is useful for deploying scalable and highly available caching solutions in AWS.

Full Code Example

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

// Step 1: Set up the VPC
const vpc = new aws.ec2.Vpc("my-vpc", {
    cidrBlock: "10.0.0.0/16",
    enableDnsHostnames: true,
    enableDnsSupport: true,
    tags: {
        Name: "my-vpc",
    },
});

const subnet1 = new aws.ec2.Subnet("my-subnet-1", {
    vpcId: vpc.id,
    cidrBlock: "10.0.1.0/24",
    availabilityZone: "us-west-2a",
    tags: {
        Name: "my-subnet-1",
    },
});

const subnet2 = new aws.ec2.Subnet("my-subnet-2", {
    vpcId: vpc.id,
    cidrBlock: "10.0.2.0/24",
    availabilityZone: "us-west-2b",
    tags: {
        Name: "my-subnet-2",
    },
});

// Step 2: Create the Subnet Group
const subnetGroup = new aws.elasticache.SubnetGroup("my-subnet-group", {
    subnetIds: [subnet1.id, subnet2.id],
    description: "My ElastiCache subnet group",
});

// Step 3: Create the ElastiCache Cluster
const cacheCluster = new aws.elasticache.Cluster("my-cache-cluster", {
    engine: "redis",
    nodeType: "cache.t2.micro",
    numCacheNodes: 1,
    subnetGroupName: subnetGroup.name,
    securityGroupIds: [], // Add security group IDs if needed
    tags: {
        Name: "my-cache-cluster",
    },
});

export const vpcId = vpc.id;
export const subnetGroupId = subnetGroup.id;
export const cacheClusterId = cacheCluster.id;
