Pulumi Cloud

Slack and Deployment Notifications

We’ve made several improvements to our Pulumi Cloud Webhooks to enhance deployment notifications and response times. Now, you can easily integrate Slack with Pulumi Cloud for organization or stack notifications without hosting their infrastructure. This integration provides centralized visibility, allowing teams to quickly access stack and update details, operation information, and user activity, streamlining collaboration and reducing context switching. Event notifications and filtering options have been expanded for both Pulumi Cloud Webhooks and the Slack integration, making deployment monitoring more efficient and accessible. These enhancements are available to all Pulumi Cloud organizations.


Microsoft Teams Webhook Integration

Setting up Microsoft Teams notifications is now easier than ever with support for Microsoft Teams formatted webhooks. You can quickly enable notifications about your Pulumi stacks and organizations in your Microsoft Teams workspace by providing an incoming webhook URL. New REST API endpoints and a Service Provider are available, allowing for efficient webhook creation at scale. These improvements enhance ChatOps workflows and provide better visibility into infrastructure changes while maintaining support for generic webhooks. For more details and how to get started, check out this blog post.

Microsoft Teams Webhooks

Admin Organization Access Tokens in Pulumi Cloud

The introduction of Admin permission scope for Organization Access Tokens provides elevated privileges for users who need them. These tokens enable actions like transferring stacks, modifying user access, team management, and more, previously restricted with regular Organization Access Tokens. Admin Organization Access Tokens cater to programmatic use cases that require higher-level permissions while maintaining a member’s usual permissions. This enhancement expands the utility of Organization Access Tokens for Enterprise and Business Critical customers, and is available during the 14-day trial period as well.

Admin Tokens

Restore Stacks

Pulumi Cloud now offers the capability to restore previously deleted stacks, a feature requested by many users. This addition enables users to recover stacks that were either mistakenly deleted or intentionally removed while retaining their activity history. This self-service recovery option can be conveniently accessed via the Pulumi Cloud console by navigating to the Stacks page, locating the “restore stacks” function, and selecting the stacks they wish to recover. Up to the last 10 deleted stacks can be restored, and older ones can be retrieved through support.

Restore Stacks

Review Stacks

New to Pulumi Deployments are Review Stacks, ephemeral cloud environments created automatically when a pull request is opened. These environments enable developers to make changes to both application and infrastructure code simultaneously, streamlining the development process. Review Stacks comment with the outputs from the deployment, making it easier to review code changes and collaborate with teammates. Review Stacks help optimize cloud costs by only existing as long as necessary during feature development. Configuring Review Stacks is a simple process that enhances development efficiency and collaboration among teams. Find more information in the Review Stacks documentation.

Review Stacks

Resource Search for Pulumi Cloud capabilities have been enhanced by allowing users to search over resource properties in addition to metadata, across over 100 cloud providers. The Property Search feature provides deeper insights into cloud infrastructure, enabling users to search based on specific property names and values, such as instance type, region, or database version. This new feature is available in the Enterprise and Business Critical editions of Pulumi Cloud and aims to streamline resource management, compliance, and diagnostics, ultimately enhancing efficiency and collaboration in cloud environments.

Dependent Stack Updates with Pulumi Deployments

Pulumi Deployments has two new features to help manage complex infrastructure projects more easily. The Deployment Webhook Destinations allow automatic triggering of updates in dependent stacks when changes occur in the parent stack. We’ve also added the Pulumi Auto Deploy Package to simplify the way you express stack dependencies, automating the creation and updating of Deployment Webhooks. For all the details and to get started, visit the blog post, auto deploy package registry page, and Pulumi Deployments documentation.


Go Generics

We’ve implemented Go generics in our SDKs, enabling type safety and reducing excessive code generation. This means you can write more reliable and maintainable infrastructure code with reduced chances of panics, leading to more robust cloud infrastructure deployments. For a deeper dive into this feature and how to get started, explore this blog post.

// Given
var a pulumi.IntOutput
var b pulumi.StringOutput

// Before (could panic at runtime if you got something wrong)
o := pulumi.All(a, b).ApplyT(func(vs []interface{}) string { // could panic
    a := vs[0].(int) // could panic
    b := vs[1].(string) // could panic
    return strconv.Itoa(a) + b
}).(pulumi.StringOutput) // could panic

// After (compile-time type-safety)
o := pulumix.Apply2(a, b, func(a int, b string) string {
    return strconv.Itoa(a) + b

Pulumi Convert

The introduction of pulumi convert in the Pulumi CLI simplifies the migration process for teams transitioning from Terraform to Pulumi. This feature allows you to convert entire Terraform projects into Pulumi, including support for modules, core Terraform 1.4 features, and most Terraform built-in functions. Starting from Pulumi CLI version 3.71.0, you can directly access this converter, streamlining the conversion of full Terraform programs. This enhancement builds upon our CrossCode foundations, enabling universal infrastructure as code support and introducing the concept of converter plugins for future integrations. This feature supports various use cases, such as migrating existing Terraform projects and modules to Pulumi, enhancing our commitment to providing versatile solutions for infrastructure as code.

$ pulumi convert --from terraform --language typescript --out pulumi
$ pulumi convert --from terraform --language python --out pulumi
$ pulumi convert --from terraform --language go --out pulumi
$ pulumi convert --from terraform --language csharp --out pulumi

Pulumi New support for SSH-style Git URLs

In the v3.77.0 release of the Pulumi CLI, we added support for pulumi new to use SSH-style Git URLs which enables accessing templates from private Git repos, authenticated via normal Git SSH support. Many teams have been building libraries of their own private templates, and this enables those templates to be used much more naturally via pulumi new and the Deploy with Pulumi button.

New Community Supported Pulumi Language - Scala

The team at Virtus Lab released support for Scala in Pulumi as part of their Besom project at https://github.com/VirtusLab/besom. As they highlight in their README:

Besom Scala SDK for Pulumi lets you leverage the full power of Pulumi Infrastructure as Code Platform using the Scala programming language. Scala support is currently in Public Beta.

The Scala language support builds on Pulumi’s existing Java and JVM support, but with an SDK custom designed to target idiomatic Scala API design patterns.

  // For each file in the directory, create an S3 object stored in `siteBucket`
  val uploads: Array[Output[s3.BucketObject]] = File(siteDir).listFiles().map { file =>
    val name = NonEmptyString(file.getName) match
      case Some(name) => name
      case None => throw new RuntimeException("Unexpected empty file name")
        bucket = siteBucket.id, // reference the s3.Bucket object
        source = FileAsset(file.getAbsolutePath), // use FileAsset to point to a file
        contentType = Files.probeContentType(file.toPath) // set the MIME type of the file
        dependsOn = siteBucket.map(List(_))
