1. Deploy Talos Linux and bootstrap a Kubernetes cluster

Before you begin

Make sure that you have nodes (bare-metal servers or VMs) that fit the hardware requirements.

Objectives

On this step of the tutorial you will bootstrap a Kubernetes cluster on Talos Linux, and make sure that it is ready to install Cozystack.

The tutorial will guide you through the following steps:

1. Install Talos Linux on your nodes or start it from another OS using kexec.
2. Bootstrap Talos to run a Kubernetes cluster.
3. Get a kubeconfig, check cluster status, and prepare to install Cozystack.

1 Install Talos Linux

Boot your machines with Talos Linux image in one of these ways:

• Quick-start Talos from another running Linux OS.
• Install using temporary DHCP and PXE servers running in Docker containers.
• Install using ISO.

2 Bootstrap Talos Cluster

Bootstrap your Talos Linux cluster using one of the following tools:

• Talm, for a declarative way of cluster management.
• talosctl, for using native talosctl tool.
• talos-bootstrap, for an interactive walkthrough.

• Talm
• talos-bootstrap
