What is Koreo?
The platform engineering toolkit for Kubernetes Last month we open sourced Koreo, our “platform engineering toolkit for Kubernetes.” Since then, we’ve seen a lot of interest from folks in the platform engineering and DevOps space. We’ve also gotten a lot of questions from people trying to better understand how Koreo fits into an already crowded landscape of Kubernetes tools. Koreo is a fairly complex tool, so it can be difficult to quickly grasp just what exactly it is_,_ what problems it’s designed to solve, and how it compares to other, similar tools. In this post, I want to dive into these topics and also discuss the original motivation behind Koreo.

Controller-Driven Infrastructure as Code
Harnessing the Kubernetes Resource Model for modern infrastructure management Infrastructure as Code (IaC) revolutionized how we manage infrastructure, enabling developers to define resources declaratively and automate their deployment. However, tools like Terraform and CloudFormation, despite their declarative configuration, rely on an operation-centric model, where resources are created or updated through one-shot commands. The evolution of IaC: From operations to controllers In contrast, Kubernetes introduced a new paradigm with its controller pattern and the Kubernetes Resource Model (KRM). This resource-centric approach to APIs redefines infrastructure management by focusing on desired state rather than discrete operations. Kubernetes controllers continuously monitor resources, ensuring they conform to their declarative configurations by performing actions to move the actual state closer to the desired state, much like a human operator would. This is known as a control loop.
