Kargo in Action is a new Manning Early Access Program (MEAP) book by Ken Cochrane, Jesse Suen, and Kent Rancourt. Rather than approaching Kargo as outside observers, the authors bring firsthand knowledge of the problems it was designed to solve, the decisions behind its architecture, and the practices that make it effective in real delivery workflows.

The book begins with a problem many engineering teams eventually encounter. CI systems are good at building and verifying artifacts, and continuous delivery tools can deploy them, but neither necessarily provides a clear, controlled process for promoting those artifacts through development, staging, and production. Teams often fill this gap with increasingly complicated pipelines, scripts, and manual approvals.

Kargo introduces a dedicated promotion control plane for GitOps. It separates deployment from promotion and gives teams a structured way to define how verified changes advance between environments. Kargo in Action explains both how to use this model and why it matters, covering governed promotion workflows, environment-specific verification, auditability, and predictable rollback.

The first three chapters are available now and explore:

The gap conventional CI/CD leaves between building software and running it in production

Why deployment and promotion should be treated as separate concerns

Where Kargo fits alongside GitOps tools and delivery platforms

How to install Kargo and begin creating your first promotion workflows

Because the book is part of MEAP, you can start reading while it is still being written and receive new chapters as they become available. It’s also an opportunity to learn Kargo directly from its builders—and to follow their thinking from the underlying delivery problem through to practical implementation.

If your team uses Kubernetes and GitOps, or if your delivery pipelines have become responsible for too many unrelated concerns, this book is worth a look.
