Creating Talos Kubernetes cluster using Proxmox.

In this guide we will create a Kubernetes cluster using Proxmox.

Video Walkthrough

How to Get Proxmox

It is assumed that you have already installed Proxmox onto the server you wish to create Talos VMs on. Visit the Proxmox downloads page if necessary.

Install talosctl

You can download talosctl via

curl<version>/talosctl-<platform>-<arch> -L -o talosctl

For example version v0.14.0 for linux platform:

curl -L -o talosctl
sudo cp talosctl /usr/local/bin
sudo chmod +x /usr/local/bin/talosctl

Download ISO Image

In order to install Talos in Proxmox, you will need the ISO image from the Talos release page. You can download talos-amd64.iso via

mkdir -p _out/
curl<version>/talos-<arch>.iso -L -o _out/talos-<arch>.iso

For example version v0.14.0 for linux platform:

mkdir -p _out/
curl -L -o _out/talos-amd64.iso

Upload ISO

From the Proxmox UI, select the “local” storage and enter the “Content” section. Click the “Upload” button:

Select the ISO you downloaded previously, then hit “Upload”

Create VMs

Start by creating a new VM by clicking the “Create VM” button in the Proxmox UI:

Fill out a name for the new VM:

In the OS tab, select the ISO we uploaded earlier:

Keep the defaults set in the “System” tab.

Keep the defaults in the “Hard Disk” tab as well, only changing the size if desired.

In the “CPU” section, give at least 2 cores to the VM:

Verify that the RAM is set to at least 2GB:

Keep the default values for networking, verifying that the VM is set to come up on the bridge interface:

Finish creating the VM by clicking through the “Confirm” tab and then “Finish”.

Repeat this process for a second VM to use as a worker node. You can also repeat this for additional nodes desired.

Start Control Plane Node

Once the VMs have been created and updated, start the VM that will be the first control plane node. This VM will boot the ISO image specified earlier and enter “maintenance mode”.

With DHCP server

Once the machine has entered maintenance mode, there will be a console log that details the IP address that the node received. Take note of this IP address, which will be referred to as $CONTROL_PLANE_IP for the rest of this guide. If you wish to export this IP as a bash variable, simply issue a command like export CONTROL_PLANE_IP=

Without DHCP server

To apply the machine configurations in maintenance mode, VM has to have IP on the network. So you can set it on boot time manually.

Press e on the boot time. And set the IP parameters for the VM. Format is:


For example $CONTROL_PLANE_IP will be and gateway

linux /boot/vmlinuz init_on_alloc=1 slab_nomerge pti=on panic=0 consoleblank=0 printk.devkmsg=on earlyprintk=ttyS0 console=tty0 console=ttyS0 talos.platform=metal ip=

Then press Ctrl-x or F10

Generate Machine Configurations

With the IP address above, you can now generate the machine configurations to use for installing Talos and Kubernetes. Issue the following command, updating the output directory, cluster name, and control plane IP as you see fit:

talosctl gen config talos-vbox-cluster https://$CONTROL_PLANE_IP:6443 --output-dir _out

This will create several files in the _out directory: controlplane.yaml, worker.yaml, and talosconfig.

Create Control Plane Node

Using the controlplane.yaml generated above, you can now apply this config using talosctl. Issue:

talosctl apply-config --insecure --nodes $CONTROL_PLANE_IP --file _out/controlplane.yaml

You should now see some action in the Proxmox console for this VM. Talos will be installed to disk, the VM will reboot, and then Talos will configure the Kubernetes control plane on this VM.

Note: This process can be repeated multiple times to create an HA control plane.

Create Worker Node

Create at least a single worker node using a process similar to the control plane creation above. Start the worker node VM and wait for it to enter “maintenance mode”. Take note of the worker node’s IP address, which will be referred to as $WORKER_IP


talosctl apply-config --insecure --nodes $WORKER_IP --file _out/worker.yaml

Note: This process can be repeated multiple times to add additional workers.

Using the Cluster

Once the cluster is available, you can make use of talosctl and kubectl to interact with the cluster. For example, to view current running containers, run talosctl containers for a list of containers in the system namespace, or talosctl containers -k for the namespace. To view the logs of a container, use talosctl logs <container> or talosctl logs -k <container>.

First, configure talosctl to talk to your control plane node by issuing the following, updating paths and IPs as necessary:

export TALOSCONFIG="_out/talosconfig"
talosctl config endpoint $CONTROL_PLANE_IP
talosctl config node $CONTROL_PLANE_IP

Bootstrap Etcd

Set the endpoints and nodes:

talosctl --talosconfig _out/talosconfig config endpoint <control plane 1 IP>
talosctl --talosconfig _out/talosconfig config node <control plane 1 IP>

Bootstrap etcd:

talosctl --talosconfig _out/talosconfig bootstrap

Retrieve the kubeconfig

At this point we can retrieve the admin kubeconfig by running:

talosctl --talosconfig _out/talosconfig kubeconfig .

Cleaning Up

To cleanup, simply stop and delete the virtual machines from the Proxmox UI.
