Hyper-V

Pre-requisities

1. Download the latest talos-amd64.iso ISO from github releases page
2. Create a New-TalosVM folder in any of your PS Module Path folders $env:PSModulePath -split ';' and save the New-TalosVM.psm1 there

Plan Overview

Here we will create a basic 3 node cluster with a single control-plane node and two worker nodes. The only difference between control plane and worker node is the amount of RAM and an additional storage VHD. This is personal preference and can be configured to your liking.

We are using a VMNamePrefix argument for a VM Name prefix and not the full hostname. This command will find any existing VM with that prefix and “+1” the highest suffix it finds. For example, if VMs talos-cp01 and talos-cp02 exist, this will create VMs starting from talos-cp03, depending on NumberOfVMs argument.

Setup a Control Plane Node

Use the following command to create a single control plane node:

New-TalosVM -VMNamePrefix talos-cp -CPUCount 2 -StartupMemory 4GB -SwitchName LAB -TalosISOPath C:\ISO\talos-amd64.iso -NumberOfVMs 1 -VMDestinationBasePath 'D:\Virtual Machines\Test VMs\Talos'

This will create talos-cp01 VM and power it on.

Setup Worker Nodes

Use the following command to create 2 worker nodes:

New-TalosVM -VMNamePrefix talos-worker -CPUCount 4 -StartupMemory 8GB -SwitchName LAB -TalosISOPath C:\ISO\talos-amd64.iso -NumberOfVMs 2 -VMDestinationBasePath 'D:\Virtual Machines\Test VMs\Talos' -StorageVHDSize 50GB

This will create two VMs: talos-worker01 and talos-wworker02 and attach an additional VHD of 50GB for storage (which in my case will be passed to Mayastor).

Pushing Config to the Nodes

Now that our VMs are ready, find their IP addresses from console of VM. With that information, push config to the control plane node with:

# set control plane IP variable
$CONTROL_PLANE_IP='10.10.10.x'

# Generate talos config
talosctl gen config talos-cluster https://$($CONTROL_PLANE_IP):6443 --output-dir .

# Apply config to control plane node
talosctl apply-config --insecure --nodes $CONTROL_PLANE_IP --file .\controlplane.yaml

Pushing Config to Worker Nodes

Similarly, for the workers:

talosctl apply-config --insecure --nodes 10.10.10.x --file .\worker.yaml

Apply the config to both nodes.

Bootstrap Cluster

Now that our nodes are ready, we are ready to bootstrap the Kubernetes cluster.

# Use following command to set node and endpoint permanantly in config so you dont have to type it everytime
talosctl config endpoint $CONTROL_PLANE_IP
talosctl config node $CONTROL_PLANE_IP

# Bootstrap cluster
talosctl bootstrap

# Generate kubeconfig
talosctl kubeconfig .

This will generate the kubeconfig file, you can use to connect to the cluster.
