The logic for validating prompted values in 'new' wasn't quite right, leading to the possibility of creating Pulumi.yaml files with blank project names. This manifests in various ways and I've hit it a number of times over the past few months because of the way we handle project/stack name conflicts in 'new' -- which itself is a bit annoying too: https://github.com/pulumi/pulumi/blob/master/pkg/cmd/pulumi/new.go#L206-L207 Because we substitue a default value of "", and because the prompting logic assumed default values are always valid, we would skip validation and therefore accept a blank Pulumi.yaml file. This generates an invalid project which causes errors elsewhere, such as error: failed to load Pulumi project located at ".../Pulumi.yaml": project is missing a 'name' attribute I hit this all the time with our getting started guide because I've gone through it so many times and have leftover stacks from prior run-throughs. I wouldn't be surprised if a lot of people hit this. The solution here validates all values, including the default. Note also that we failed to validate the value used by 'new --yes' which meant you could bypass all validation by passing --yes, leading to similar outcomes. I've added a couple new tests for these cases. There is a risk we depend on illegal default values somewhere which will now be rejected, but that would seem strange, and assuming the tests pass, I would assume that's not true. Let me know if that's wrong. Fixes pulumi/pulumi#3255. |

Pulumi's Infrastructure as Code SDK is the easiest way to create and deploy cloud software that use containers, serverless functions, hosted services, and infrastructure, on any cloud.
Simply write code in your favorite language and Pulumi automatically provisions and manages your AWS, Azure, Google Cloud Platform, and/or Kubernetes resources, 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:
let aws = require("@pulumi/aws");
let sg = new aws.ec2.SecurityGroup("web-sg", {
ingress: [{ protocol: "tcp", fromPort: 80, toPort: 80, cidrBlocks: ["0.0.0.0/0"]}],
});
for (let i = 0; i < 3; i++) {
new aws.ec2.Instance(`web-${i}`, {
ami: "ami-7172b611",
instanceType: "t2.micro",
securityGroups: [ sg.name ],
userData: `#!/bin/bash
echo "Hello, World!" > index.html
nohup python -m SimpleHTTPServer 80 &`,
});
}
Or a simple serverless timer that archives Hacker News every day at 8:30AM:
const aws = require("@pulumi/aws");
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 * * ? *)", () => {
require("https").get("https://news.ycombinator.com", res => {
let content = "";
res.setEncoding("utf8");
res.on("data", chunk => content += chunk);
res.on("end", () => new aws.sdk.DynamoDB.DocumentClient().put({
TableName: snapshots.name.get(),
Item: { date: Date.now(), content },
}).promise());
}).end();
});
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:
-
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
-
Create a Project:
After installing, you can get started with the
pulumi new
command:$ mkdir pulumi-demo && cd pulumi-demo $ pulumi new hello-aws-javascript
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 created an AWS Serverless Lambda project written in JavaScript. -
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 up
s will compute the minimal diff to deploy your changes. -
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)
-
Access the Logs:
If you're using containers or functions, Pulumi's unified logging command will show all of your logs:
$ pulumi logs -f
-
Destroy your Resources:
After you're done, you can remove all resources created by your program:
$ pulumi destroy -y
