Installing Cozystack as a Platform

The third step in deploying a Cozystack cluster is to install Cozystack on a Kubernetes cluster that has been previously installed and configured on Talos Linux nodes. A prerequisite to this step is having installed a Kubernetes cluster.

If this is your first time installing Cozystack, consider starting with the Cozystack tutorial.

To plan a production-ready installation, follow the guide below. It mirrors the tutorial in structure, but gives much more details and explains various installation options.

Overview

Cozystack can be used in BYOP (Build Your Own Platform) mode — similar to how Linux distributions let you install only the packages you need. Instead of deploying the full platform with all components, you selectively install only what you need from the Cozystack package repository.

This approach is useful when:

You have an existing Kubernetes cluster and only need specific components (e.g., a Postgres operator or monitoring).
Your cluster already has networking (CNI) and storage configured, and you don’t want Cozystack to manage them.
You want full control over which components are installed and how they are configured.

The workflow relies on two Kubernetes resources managed by the Cozystack Operator:
