Installing and Configuring Kubernetes Cluster

The second step in deploying a Cozystack cluster is to install and configure a Kubernetes cluster. The result is a Kubernetes cluster installed, configured, and ready to install Cozystack.

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

Installation Options

Talos Linux (Recommended)

For production deployments, Cozystack recommends Talos Linux as the underlying operating system. A prerequisite to using these methods is having installed Talos Linux.

There are several methods to configure Talos nodes and bootstrap a Kubernetes cluster:

• Recommended: using Talm, a declarative CLI tool, which has ready presets for Cozystack and uses the power of Talos API under the hood.
• Using talos-bootstrap, an interactive script for bootstrapping Kubernetes clusters on Talos OS.
• Using talosctl, a specialized command-line tool for managing Talos.
• Air-gapped installation is possible with Talm or talosctl.

Generic Kubernetes

Cozystack can also be deployed on other Kubernetes distributions:

• Generic Kubernetes — deploy Cozystack on k3s, kubeadm, RKE2, or other distributions.

If you encounter problems with installation, refer to the Troubleshooting section.

Further Steps

• After installing and configuring Kubernetes on top of Talos Linux nodes, you will have a Kubernetes cluster ready to install and configure Cozystack.
