Getting started with GitOps can feel like trying to herd cats through a YAML factory while the factory is on fire. It’s one of those things that seems like it ought to be simple (just use Git!), but in practice is much more complex — and you may not realize how much more complex until you’re weeks or more into a project. After years of running GitOps workflows in production across dozens of clusters, I’ve collected a list of best practices that I’m hoping can save you from having to make many of the mistakes I’ve made. Think of it as the GitOps cheat sheet I wish I’d had from Day 1.

We’re excited to announce the release of Pulumi Kubernetes Operator v2.3.0, introducing two powerful capabilities that enhance GitOps workflows: preview mode for validating infrastructure changes before deployment, and structured configuration support for managing complex data types. Building on the success of the v2.0 GA release, this update addresses long-standing community requests while maintaining full backwards compatibility. These features enable safer, more sophisticated infrastructure management patterns for platform engineering teams.

The Pulumi Kubernetes Operator (PKO) enables you to manage Pulumi stacks as Kubernetes resources, but it doesn’t provide much guidance on change management. Kargo fills this gap by providing controlled, staged promotions with verification steps. Together, they let you keep your infrastructure defined in Pulumi while managing multi-environment rollouts in a systematic way.

This pattern is especially useful for platform teams that need to balance delivery speed with governance as environments and expectations scale.

Kubernetes continues to evolve, powering not only applications but entire AI and ML systems across clouds, edges, and enterprises. By 2026, DevOps engineers, SREs, cloud engineers, and platform teams face growing pressure to deliver faster, smarter, and more secure infrastructure at scale.

Kubernetes automation is entering a new era where infrastructure as code, policy enforcement, and AI-driven orchestration work together to manage cloud environments intelligently.

Pulumi’s 2025 advancements, including Pulumi Kubernetes Operator 2.0 GA, new Kubernetes best practices playbooks, Pulumi Neo for AI assisted infrastructure management, and Policy Automation, set the foundation for a new era of Kubernetes automation that extends across every role involved in managing modern infrastructure.

In today’s complex digital landscape, organizations are increasingly turning to platform engineering to optimise their software delivery processes and maximize efficiency. The growing complexity of modern applications, coupled with the need for rapid, secure, and scalable deployments, has created a pressing demand for robust Internal Developer Platforms (IDPs).

IDPs are a key component of modern platform engineering strategies. An IDP is a self-service layer that sits on top of an organization’s infrastructure, abstracting away complexity and providing developers with the tools and environments they need to build, test, and deploy applications efficiently.

This time last year, I presented Applying the Law of Demeter to GitOps at GitOps Days 2020. The Law of Demeter is a design principle, proposed in 1988, which encourages loose coupling between systems. During this session, I wanted the audience to understand and be able to identify when their applications and continuous delivery pipelines have too much knowledge of the platform in which they’re going to run. As an industry, we’re seeing a great deal of momentum towards Platform Engineering and with this comes a Broca divide, a strict division of responsibilities: to build a platform and to consume a platform.
