Build Your Own Platform (BYOP)

How to build your own platform with Cozystack by installing only the components you need

Cozystack can be used in BYOP (Build Your Own Platform) mode — installing only the components you need from the Cozystack package repository, rather than deploying the full platform.

Overview

Cozystack provides a package management system inspired by Linux distribution package managers. The Cozystack Operator manages PackageSource and Package resources, while the cozypkg CLI tool provides an interactive interface for listing available packages, resolving dependencies, and installing them selectively.

This approach is useful when:

  • You have an existing Kubernetes cluster and only need specific components.
  • Your cluster already has networking and storage configured.
  • You want full control over which components are installed.

The default variant of cozystack-platform installs no components — it only registers PackageSources. From there, you use cozypkg to install individual packages like networking, storage, ingress, database operators, and more.

For a step-by-step guide, see the BYOP installation guide.
