Today, we’re excited to announce several new open source projects that advance Pulumi’s Kubernetes support. These projects and features have been developed while helping leading cloud native engineering teams like Snowflake, Lemonade, and Mercedes-Benz go into production with Kubernetes, and include new deployment automation options, improved ecosystem integrations, and tools to make it easier than ever to adopt Pulumi for new and existing projects.

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 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.

Kubernetes developers and operators work together to manage workloads and to continuously ship software through CI/CD. These users have an affinity for automation and pipelines, and richer integration with Kubernetes is a growing theme across the cloud native ecosystem.

We’re excited to introduce the Pulumi Kubernetes Operator: a Kubernetes controller that deploys cloud infrastructure in Pulumi Stacks for you and your team.

These program stacks include virtual machines, block storage, managed Kubernetes clusters, API resources, serverless functions and more!

Your application made it out of the dev stage, passed the testing stage, and arrived in production. As a developer, you might think that it’s an ops problem now. However, DevOps is a collaborative effort between developers and operators to build and maintain applications using shared techniques and processes, often called “Day 2” activities.

Customers and users have asked for the ability to change the secrets manager associated with their stacks. This would allow a user to rotate their secrets providers when people leave their organization or even to be able to migrate to another secret manager of their choice. The v2.8.0 release of Pulumi adds support for this specific feature.

Let’s have a look at how to change a secrets provider for an existing stack:

In previous installments, we examined how to deploy applications. However, we only touched on how applications talk to each other inside and outside the cluster. Whether you are building a modern application or modernizing a legacy application, understanding how resources and components talk to each other is essential. In this installment, we’ll examine networking in Kubernetes.

This article is the fourth in a series using infrastructure as code to deploy applications with Kubernetes. This series walks you through:

• Building a Kubernetes cluster on cloud providers
• Basic application deployment
• Advance application deployment and Helm charts
• Stateful applications
• Networking
• “Day 2” activities such as migrating node groups.

In the previous post, we examined different methods for deploying applications. We worked through examples of a boilerplate deployment, to one using ComponentResources to automate deployment further, and deploying with Helm charts. In this installment, we’ll look at how to deploy stateful applications, such as databases, in Kubernetes. Unlike stateless applications, stateful apps require persistent storage, which presents scaling and availability challenges.

One of the major advantages of using containers for development is reducing the need to install software and associated dependencies. Developers can start writing code without configuring a development environment that emulates production. The Visual Studio Code Remote - Containers extension lets you develop inside a container. If you want to use Pulumi’s infrastructure as code engine without installing the Pulumi CLI, this blog post is for you!
