Infrastructure as Code for Humans and Agents

Pulumi Infrastructure as Code is the easiest way to build and deploy infrastructure, of any architecture and on any cloud, using programming languages that you already know and love. Code and ship infrastructure faster with your favorite languages and tools, and embed IaC anywhere with Automation API.

Simply write code in your favorite language and Pulumi automatically provisions and manages your resources on
AWS,
Azure,
Google Cloud Platform,
Kubernetes, and 300+ providers using an
infrastructure-as-code approach.
Skip the YAML, and use standard language features like loops, functions, classes,
and package management that you already know and love.

For example, create three web servers:

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

const ami = aws.ec2.getAmiOutput({
    mostRecent: true,
    owners: ["amazon"],
    filters: [{ name: "name", values: ["al2023-ami-*-x86_64"] }],
});

const sg = new aws.ec2.SecurityGroup("web-sg", {
    ingress: [{ protocol: "tcp", fromPort: 80, toPort: 80, cidrBlocks: ["0.0.0.0/0"] }],
});

for (const i of [0, 1, 2]) {
    new aws.ec2.Instance(`web-${i}`, {
        ami: ami.id,
        instanceType: "t3.micro",
        vpcSecurityGroupIds: [sg.id],
        userData: `#!/bin/bash
            echo "Hello, World!" > index.html
            nohup python3 -m http.server 80 &`,
    });
}

Or a simple serverless timer that archives Hacker News every day at 8:30AM:

import * as aws from "@pulumi/aws";
import { DynamoDBClient } from "@aws-sdk/client-dynamodb";
import { DynamoDBDocumentClient, PutCommand } from "@aws-sdk/lib-dynamodb";

const snapshots = new aws.dynamodb.Table("snapshots", {
    attributes: [{ name: "id", type: "S" }],
    hashKey: "id",
    billingMode: "PAY_PER_REQUEST",
});

aws.cloudwatch.onSchedule("daily-yc-snapshot", "cron(30 8 * * ? *)", async () => {
    const res = await fetch("https://news.ycombinator.com");
    const content = await res.text();

    const client = DynamoDBDocumentClient.from(new DynamoDBClient({}));
    await client.send(new PutCommand({
        TableName: snapshots.name.get(),
        Item: { id: `${Date.now()}`, content },
    }));
});

Many examples are available spanning containers, serverless, and infrastructure in
pulumi/examples.

Pulumi is open source under the Apache 2.0 license, supports many languages and clouds, and is easy to extend. This
repo contains the pulumi CLI, language SDKs, and core Pulumi engine, and individual libraries are in their own repos.

Getting Started


See the Get Started guide to quickly get started with
Pulumi on your platform and cloud of choice.

Otherwise, the following steps demonstrate how to deploy your first Pulumi program, using AWS
Serverless Lambdas, in minutes:

1. Install:

To install the latest Pulumi release, run the following (see full
installation instructions for additional installation options):

    curl -fsSL https://get.pulumi.com/ | sh

1. Create a Project:

After installing, you can get started with the pulumi new command:

    mkdir pulumi-demo && cd pulumi-demo
    pulumi new serverless-aws-typescript

The new command offers templates for all languages and clouds. Run it without an argument and it'll prompt
you with available projects. This command creates an AWS Serverless Lambda project written in TypeScript.

1. Deploy to the Cloud:

Run pulumi up to get your code to the cloud:

    pulumi up

This makes all cloud resources needed to run your code. Simply make edits to your project, and subsequent
pulumi ups will compute the minimal diff to deploy your changes.

1. Use Your Program:

Now that your code is deployed, you can interact with it. In the above example, we can curl the endpoint:

    curl $(pulumi stack output url)

1. Access the Logs:

If you're using containers or functions, Pulumi's unified logging command will show all of your logs:

    pulumi logs -f

1. Destroy your Resources:

After you're done, you can remove all resources created by your program:

    pulumi destroy -y

To learn more, head over to pulumi.com for much more information, including
tutorials, examples, and
details of the core Pulumi CLI and programming model concepts.
