Pulumi Automation API

Pulumi’s Automation API was released in preview last year and is now GA as part of Pulumi 3.0. It provides an API for embedding Pulumi within your own applications, and supports all Pulumi languages including TypeScript/JavaScript, Python, Go, and C#. Instead of working with the pulumi CLI directly, or writing scripts to execute the CLI within your CI/CD environment, you can now build your own software solutions that build on top of Pulumi’s robust, desired state infrastructure as code deployment engine. It’s simple to embed Pulumi in your software-defined workflows with just a few lines of code.

This opens up so many exciting new opportunities for how your team can manage cloud infrastructure; we’ve seen amazing creativity as Pulumi’s customers and communities have created solutions on top of Automation API. In addition, Pulumi Automation API powers several other new features like the Pulumi Kubernetes Operator, the Pulumi GitHub Action v3, and Concourse CI support for Pulumi.

Native Providers for Azure and Google Cloud

Pulumi offers packages for managing cloud infrastructure in more than 50 cloud and SaaS applications, with more than a dozen new providers added since Pulumi 2.0 including partnerships with Civo, Venafi, Okta, Auth0, Equinix Metal, Spot Ocean for Azure, and Splunk.

For the largest and most widely used cloud providers, we’ve created something new: Pulumi native providers, which give you the most complete and consistent interface for the modern cloud. These native providers are automatically generated from cloud provider APIs and resource models that are maintained directly by cloud provider service teams. This enables native providers to offer 100% API coverage, same-day support for new features, the exact same API designed by the provider service team, and fewer bugs and reliability issues. This makes native providers the best way to manage infrastructure in the supported cloud platforms, combining the benefits of Pulumi Infrastructure as Code with the resource models and pace of delivery of the cloud provider themselves.

Along with Pulumi 3.0, the new Azure Native provider, originally released in preview last year, is now generally available as version 1.0. The Azure Native provider is built on top of the Azure Resource Manager REST API specifications developed and maintained by Azure service teams. It supports more than 2x the number of resources, and 3x the number of resource properties as the classic Azure provider. Azure Native also supports every version of each resource API for maximum compatibility with your existing infrastructure. New versions of the Azure Native provider with support for the latest features of Azure are published every night, ensuring immediate availability of new features and improvements from the Azure service teams.

Today, we’re also excited to be releasing a preview of the new Google Cloud Native provider. This native provider offers 100% coverage of the Google Cloud platform, with 70% more resource properties supported compared to the existing provider. It also supports every version of each supported resource, including alpha, beta, and GA Google Cloud offerings.

👉 Read more in the Pulumi Native Providers blog post and the Pulumi Google Native Provider blog post. And of course, we haven’t forgotten AWS - an AWS Native provider is expected later this year.

Pulumi Packages and Multi-Language Components

Pulumi Packages are the core technology that enables cloud infrastructure resource provisioning to be defined once, and made available to users in all languages supported by Pulumi. If you’ve ever used a cloud provider in Pulumi, you’ve used a Pulumi Package. With Pulumi 3.0, we are extending Pulumi Packages to also support building and packaging Pulumi Components: higher-level abstractions over cloud infrastructure patterns described as normal Pulumi programs. This makes it easy to take a Pulumi program that defines a collection of resources and turn it into something reusable: a Pulumi Package that can be published and used by all Pulumi users, across all languages supported by Pulumi.

One example of building and packaging Pulumi Components as a Pulumi Package is the Pulumi EKS package. We originally released a component for easily building and managing production-ready EKS clusters nearly two years ago, but it was only available for Node.js users of Pulumi as an npm package. This component has been incredibly popular, as it abstracts away a lot of complexity in all the moving pieces that need to be managed to stand up an EKS cluster across both AWS resources and in-cluster Kubernetes resources. Recently, we turned this component into a Pulumi Package, making it available to users in Python, Go, and .NET as well, with just a single implementation. Pulumi EKS is just the first example of applying this technology; there’s a lot more in the works here in the coming months!

import pulumi
import pulumi_eks as eks

cluster = eks.Cluster("my-cluster")

pulumi.export("kubeconfig", cluster.kubeconfig)
package main

import (

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		cluster, err := eks.NewCluster(ctx, "my-cluster", nil)
		if err != nil {
			return err
		ctx.Export("kubeconfig", cluster.Kubeconfig)
		return nil
import * as eks from "@pulumi/eks";

const cluster = new eks.Cluster("my-cluster");

export const kubeconfig = cluster.kubeconfig;
using Pulumi;
using Pulumi.Eks;

class MyStack : Stack
    public Output<object> Kubeconfig { get; set; }

    public MyStack()
        var cluster = new Cluster("my-cluster");

        Kubeconfig = cluster.Kubeconfig;

All Pulumi packages define a common Pulumi schema, which describes the resource model the package exposes and can be used to generate language-specific SDKs and documentation. There are several different types of Pulumi Package:

  • Native Pulumi Provider Package: Use the full features of the Pulumi resource model to create a provider for a new cloud platform. Examples: the kubernetes, azure-native, and google-native packages.
  • Bridged Provider Package: Take an existing resource provider from another supported ecosystem (like a Terraform provider), and bridge it to be exposed as a Pulumi Package. Examples:the aws, tls, and cloudflare packages.
  • Component Package: Write a Pulumi Component in your language of choice and expose it to users in all languages supported by Pulumi. Example: the eks package.

Together, these options provide a combination of breadth and depth for the kinds of resources and components that can be exposed to Pulumi developers via Pulumi Packages.

Improved Go and Python SDKs

Pulumi’s language SDKs bring the power of cloud infrastructure management into your language of choice in a natural and productive way, enabling you to use all of your existing software engineering knowledge and tools for your cloud infrastructure projects as well. In Pulumi 3.0, we’ve made improvements to the Go and Python SDKs to improve developer productivity and enable additional tooling.

For Go users, Pulumi 3.0 reduces binary sizes by 4x and improves build times by up to 3x, leading to a much faster infrastructure development loop. Along with this, the Go APIs for working with Pulumi Output values have been simplified to provide a single way of transforming outputs instead of three different options. This makes the Pulumi Go SDK more consistent and easier to get started with. You can learn more about these changes in the Pulumi 3.0 migration guide.

For Python users, Pulumi 3.0 brings a new, more strongly typed way to provide inputs to cloud resources, ensuring that users get completion lists, type checking, documentation, and more within their IDE of choice. Along with this, some inconsistencies in input property naming have also been removed; now, all property names follow a consistent and predictable naming convention. You can learn more about these changes in the Pulumi 3.0 migration guide.

New Integrations and Features in the Pulumi Service

In addition to the Pulumi 3.0 open source release, we’re also making available new features for users of the Pulumi Service: the simple and easy to use default backend for all Pulumi users, with additional features for teams and enterprises.

Integrating Pulumi into CI/CD systems is a key step in realizing the full benefits of modern infrastructure as code, and we’ve worked to make this easier than ever. Since 2.0, we’ve added partner integrations with Spinnaker, GitHub Actions and CodeFresh as well as a new Pulumi Kubernetes Operator. In addition, we’ve introduced a new CI/CD Assistant to the service to help configure version control and CI/CD integration for your Pulumi projects with just a few clicks.

For enterprise users, we’ve added several enhancements to SAML SSO and SCIM support. Pulumi’s SSO support now works seamlessly with Okta (as well as Google Identity, Azure Active Directory and more), users and groups can now be synced via SCIM support in your SAML provider, and new Team Admin roles make team management simpler for large organizations.

Lastly, the Pulumi Service now offers a dashboard landing page which brings insights about your infrastructure front-and-center whether you are an individual user, or part of a large organization.
