Build, test, and debug your code directly inside a Kubernetes cluster — DevSpace closes the inner development loop.

Welcome to DevSpace: The Inner Loop for Kubernetes Development.

DevSpace is a lightweight, client-only command-line tool that makes developing applications on Kubernetes feel fast and immediate. Instead of rebuilding an image and redeploying a pod for every code change, DevSpace syncs your files straight into a running container, forwards its ports to your laptop, and streams its logs back to your terminal — so the cluster behaves like a local runtime. This book starts with the inner-loop problem DevSpace exists to solve, then works through its client-only architecture, the devspace.yaml configuration file at its center, image building and deployment, the development services that power hot reloading and port forwarding, the POSIX pipelines that orchestrate everything, dependencies for multi-service projects, and finally the practices that make DevSpace work well on a real team. By the end you will understand not just which commands to run, but why DevSpace is shaped the way it is.
