Back in September 2021 we announced public preview for the Helm Release resource in Pulumi’s Kubernetes provider. Over the last few months, we have had a very encouraging uptake in usage and several meaningful discussions with users in the community that have helped shape improvements to this resource. Thanks to this collaboration, we are now pleased to announce that the Helm Release resource is now GA (generally available) starting in v3.15.0 of the Pulumi Kubernetes Provider and SDK in all Pulumi supported languages. We are excited to offer yet another tool to Pulumi users to effectively manage their Kubernetes footprint.

Last year we released the Pulumi Kubernetes Operator, a new cloud-native way to manage and deploy cloud infrastructure using Pulumi from within your Kubernetes environment. Since then, we’ve worked with many Pulumi users who have adopted the Pulumi Kubernetes Operator at increasingly larger scales and for a wide variety of use cases. Today, we’re excited to make the 1.0 release of the Pulumi Kubernetes Operator available.

The Pulumi Kubernetes Operator defines a Kubernetes Custom Resource called pulumi.com/v1/Stack, which represents a Pulumi stack. The Pulumi stack can be authored in any supported Pulumi language (TypeScript, Python, Go, .NET) and can deploy and manage cloud infrastructure in any supported cloud (AWS, Azure, GCP, Kubernetes and 60+ additional cloud and SaaS providers). The Pulumi Kubernetes Operator triggers cloud deployments based on changes to the Stack Custom Resource or the resources it tracks.

As a result, the Pulumi Kubernetes Operator enables users to specify the desired state of their cloud infrastructure using resources managed directly in their Kubernetes cluster, which trigger creation, update and deletion of the detailed cloud infrastructure they need.

Kubernetes has been a significant focus of Pulumi since its very beginnings. Pulumi added support for installing Helm charts way back in 2018 and it has seen significant adoption by users since. However, Pulumi’s current Chart integration lacks support for some increasingly common advanced features in Helm charts, e.g.:

1. Support for Helm lifecycle hooks
2. Handling sub-charts and dependencies

As Helm and its usage evolved over the years, Pulumi users using the Chart resource have often had to get very creative in order to get the desired functionality in their deployments.

Today we are excited to announce the public preview of a new Helm Release resource starting with v3.7.0 of the Pulumi Kubernetes Provider and SDK in all Pulumi supported languages. This new resource provides Pulumi users more options to choose the right tool for their use-case. The rest of this blog post will highlight how this resource differs from the existing Helm Chart component resource and describe how and when to use the new resource.
