Kubernetes resources often have more than one controller making changes to them. These controllers can include kubectl, the Kubernetes control plane, custom operators, or infrastructure as code (IaC) tools like Pulumi. With the v3.20.1 release of the Kubernetes provider, you have some powerful new options for managing shared resources in Kubernetes. In this post, we show you how Pulumi can help you work with shared resources safely and effectively.

Pulumi’s infrastructure as code tooling combines the programming languages and tools you already know with the full power of cloud infrastructure. But until now, some Pulumi components for cloud infrastructure, like our popular EKS package for Amazon’s Elastic Kubernetes Service, were only available in a subset of the languages supported by Pulumi.

Now, you can use the EKS package–previously only available for TypeScript–in all four Pulumi languages: TypeScript, Python, .NET, and Go. Regardless of the language you choose, you can manage EKS clusters with Pulumi, starting with the v0.22.0 release. Check out our Modern Infrastructure Wednesday video to see it in action:

Provisioning, managing, and monitoring a Kubernetes cluster is not easy. AWS now offers EKS to reduce that burden – but it’s still difficult to get up and running. Pulumi’s infrastructure as code SDKs can help! We can provision an entire EKS cluster with a single CLI command, thanks to the @pulumi/eks package. Let’s see how.

Kubernetes users often joke about being “YAML engineers,” and the pile of YAML seems to get deeper every day. Today, we’re pleased to announce kube2pulumi, a tool to automatically convert Kubernetes manifests into modern code! Instead of manipulating YAML directly, you can take advantage of the rich ecosystem of programming language tools to supercharge your productivity.

CustomResources in Kubernetes allow users to extend the API with their types. These types are defined using CustomResourceDefinitions (CRDs), which include an OpenAPI schema. This extensibility is quite useful but comes at the cost of complex YAML definitions. Our new crd2pulumi tool takes the pain out of managing CustomResources by generating types in the Pulumi-supported language of your choice!

Kubernetes is complex, and there are many ways to manage Kubernetes resources. Pulumi supports many of these options, including native code SDKs, YAML, Helm, and now, Kustomize. There’s no need to rewrite your existing configurations to get started with Pulumi. You can efficiently adopt existing resources to deploy your modern application and save time and effort.

You’ve containerized your application, and it’s running great on your desktop using Docker Compose or Swarm. But now it’s time to test it locally with minikube and then put it into production with Kubernetes. Manifests are a bit like Compose files - it’s just YAML, right?

We’re excited that Go is now a first-class language in Pulumi and that you can build your infrastructure with Go on AWS, Azure, GCP, and many other clouds. Users often ask, “Can I use Pulumi to manage Kubernetes infrastructure in Go today?” With the release of Pulumi 2.0., the answer is “Yes!”

Stop writing Kubernetes YAML by hand, and start using the power of familiar programming languages! Pulumi can generate Kubernetes manifests that easily integrate into existing CI/CD workflows.

Kubernetes provides a rich, standards-based API that works across cloud and on-premise infrastructure. However, many of the API fields are deeply nested and require users to specify the same values redundantly across different resources. While this explicit specification is necessary for Kubernetes to operate, this often leads users to copy-paste existing code to manage the boilerplate. Today, as part of our Crosswalk for Kubernetes announcement, we’re introducing the Kubernetes Extensions (kx) library for Pulumi.
