ellismg Rework get-version scripts
Under our old versioning system, when we started a new point release,
we'd tag the HEAD commit of master with a tag like `v0.16.6-dev` and
our scripts would use this to generate a new version number. This
required a great deal of gymnastics when producing a release and
caused us to litter these -dev tags everywhere.

To improve this, we change version number generation to the following

1. If the commit we are building has a tag applied to it, use that tag
as the version (appending the dirty bit metadata to the version, if

2. If the commit we are bulding does not have a tag applied to it,
take the version from the next reachable tag, increment the patch
version and then append the `-dev` pre-release tag. As part of this,
we also make a slight tweek to our semver generation such that instead
of `-dev<TIMESTAMP>` we use `-dev.<TIMESTAMP>` which is more in line
with what semver recommends.

Pulumi's Cloud Native SDK is the easiest way to create and deploy cloud programs 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: [""]}],
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:

let cloud = require("@pulumi/cloud");
let snapshots = new cloud.Table("snapshots");
cloud.timer.daily("daily-yc-snapshot", { hourUTC: 8, minuteUTC: 30 }, () => {
    let req = require("https").get("https://news.ycombinator.com", (res) => {
        let content = "";
        res.on("data", (chunk) => { content += chunk });
        res.on("end", () => {
           snapshots.insert({ date: Date.now(), content: 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: get up and running quickly.

  • Tutorials: walk through end-to-end workflows for creating containers, serverless functions, and other cloud services and infrastructure.

  • Examples: browse a number of useful examples across many languages, clouds, and scenarios including containers, serverless, and infrastructure.

  • A Tour of Pulumi: interactively walk through the core Pulumi concepts, one at a time, covering the entire CLI and programming model surface area in a handful of bite-sized chunks.

  • Reference Docs: read conceptual documentation, in addition to details on how to configure Pulumi to deploy into your AWS, Azure, or Google Cloud accounts, and/or Kubernetes cluster.

  • Community Slack: join us over at our community Slack channel. Any and all discussion or questions are welcome.

Getting Started

Follow these steps 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
  2. Configure your Cloud Provider so that Pulumi can deploy into it.

  3. Create a Project:

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

    $ 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.

  4. Deploy to the Cloud:

    Run pulumi update to get your code to the cloud:

    $ pulumi update

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

  5. 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)
  6. Access the Logs:

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

    $ pulumi logs -f
  7. Destroy your Resources:

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

    $ pulumi destroy -y

Please head on over to the project website for much more information, including tutorials, examples, and an interactive tour of the core Pulumi CLI and programming model concepts.
