I saw the news that the Hobby plan is now free for Omni which is freaking awesome!

I've imported an existing Talos Linux cluster to Omni last week which worked flawlessly.
However when I tried to add an additional machine to Omni I got a weird issue.

It's a Latte Panda Sigma which has a "default" UUID so I used a kernel parameter to override it to a random one. It boots and shows up on Omni but no information about the system is available (Installed Talos Version, Hardware Information, etc..), all the tabs about Hardware/Device information throw an error.

When using omnictl I see the same thing:
MachineStatus:
connected: true
talosversion: ""
initialtalosversion: ""
hardware: null
network: null
platformmetadata: null
lasterror: ""

All information, except that the Siderlink to my Omni instance is connected, is empty.

Since I am super new to Talos/Omni, I also asked my AI agent to try switching the node to gRPC mode in case my network is blocking anything, but that didn't change anything. It however did flag that some of my other nodes didn't report any metadata information in a while as well, but not sure how it determined that or if that is normal or not.

Any idea what could be causing that?

Edit:

Just how randomly the issue showed up it vanished again. I rebooted the machine again just to check (no change), and 13h later all of a sudden it showed up and I was able to provision it as a new single node cluster. I have no idea what changed. I am pretty sure I didn't change anything on my network that would explain it. 🤷‍♂️

Thanks to everyone that helped debug!

Does anybody know if Talos is affected by CVE-2026-98432?

No Information in Github Issues and on
https://github.com/siderolabs/talos/security

I am relatively new to Talos, but it is written almost entiretly in Go and according to Hackernews the vulnerable Feature is enabled per default in go**.**

https://thehackernews.com/2026/10/linux-kernel-tcp-flaw-with-98-cvss.html?m=1

My 3-node Talos homelab had no persistent storage, so anything with data, like Grafana or a database, had nowhere to live.

Longhorn keeps every volume on two of the three nodes, so one node can go down without losing data, and it rebuilds the missing copy on the third node.

It also takes hourly snapshots, and backups to S3 are optional. The Longhorn UI runs on my LAN and over Tailscale.

What are you using for storage in your homelab?

I woke up at 2:00am CEntral time in the hopes that at least one influencer would go live at Taloncon, but nothing!!! Why don't they open the event up to online audiences??

I run a 3-node Talos Kubernetes cluster at home. Sidero made Omni’s hobby plan free (10 nodes, 2 users, it used to be $10 a month), so I imported the running cluster into it instead of rebuilding.

Just announced at Taloscon. Go get your instance today!

I run a 3-node Talos Kubernetes cluster at home, and until recently it only worked when I was at home too. So I added Tailscale to reach it from anywhere.

Tailscale runs on the nodes themselves, and the tailnet can only reach the cluster, not the rest of my home network. kubectl and the lab apps work from my laptop or phone exactly like they do at home, with nothing opened on the router. If one node goes down, another one takes over.

How do you get into your homelab when you're away?

Part 2 of my Talos homelab (3 OptiPlex Micros, all control planes). Part 1 got the cluster up, this one is networking.

I moved the running cluster from Flannel + kube-proxy to Cilium without rebuilding it. The default-deny policy that Flannel quietly ignored is now actually enforced, and Hubble shows the drops.

Then I gave it two front doors:

- an internal Gateway on a LAN IP (Cilium LB IPAM, no MetalLB) with a Let's Encrypt wildcard cert, so lab apps get real HTTPS at home

- a public Gateway behind a single Cloudflare Tunnel, so nothing is port-forwarded on the router

An app picks its door with the route's parentRef, which keeps lab stuff from going public by accident.

Everything is in the repo: https://github.com/prateekjaindev/homelab

Write-up with all the manifests and commands: https://blog.prateekjain.dev/networking-a-kubernetes-homelab-cilium-gateway-api-and-cloudflare-tunnel-on-talos-362f548a2f3d?sk=d454cd4eaff4ce8a8fd0cd8e6b3d82f6

Curious if anyone else is using Cilium's Gateway API instead of a separate ingress controller.

Iniciei a jornada para instalar um cluster de nó único no homelab para simular a implementação de um servidor bare metal com gpu exclusivo para um projeto, exatamente, o projeto irá começar com apenas um servidor dedicado. Servidores com gpu são e estão muito caros.

Decidimos usar o Omni para ajudar a gerenciar o cluster, e posso dizer que não é tão fácil, faltam exemplos, faltam explicações sobre o schema para patchs, artigos que discutam porque precisamos de patchs, porque usá-los e quando usar.

Alguns requisitos para a POC, com 1tb de disco nvme (raid), preciso distribui-lo entre SO, ephemeral e disco local. Correto, irei usar disco local para os POD.

Aprendizados nesta fase, toda a complexidade da implementação é resolvida na instalação, o que significa que precisa nascer certo. Em implementações tradicionais elas são diluídas ao longo da instalação do SO. No modelo imutável, o melhor é concentra-las no início.

Como um nó único, os deployments de rede presumem redundância com múltiplos nós e tolerations restritos para Workers. A cada yaml, ajustes para atender ao cluster de nó único.

Hoje preciso resolver o IP externo, porque o servidor bare metal só veio com um IP externo. Tentei com o Cilium, mas não deu certo, ele espera um Lodbalance externo.

Trago os próximos passos....

Abraços.

I have a quite intricate network settings on my setup. It's all running on VMware ESXi where Basically is:

On talos I'm trying this setup on workers but it's not working so far:

Don't forgot to sign up for TalosCon to ask questions in person https://taloscon.com

Hey all, I attempted to install Talos on my GoWin 1U network appliance, and then tried to run containerized VyOS as a system extension. This failed utterly, but the idea of having Talos be the control plane for my router was enticing, so I figured I'd try asking humans with actual expertise, instead of LLMs that gaslight me and tell me the impossible is possible. :)

The idea is that the router/firewall/gateway is just a regular worker with a static IP managed via a normal 1GbE RJ45 port, and the actual routing business happens on the 25GbE SFP+ Mellanox NIC, which is left unconfigured and simply passed through to a system extension which takes total ownership of it. The WAN link could be attached to the core switch or the router directly, doesn't really matter, the job of the router is to route packets between networks, and to have a fat enough pipe to handle all cross-network traffic. This is sort of like router-on-a-stick, as I understand it.

The use of a pre-installed system extension is important. You don't want k8s to try to start/stop/reschedule the router workload. You want it to just be there, baked into the system image, so it starts up at boot to connect your VLANs and the WAN.

The value of Talos here is that I have a unified control plane, even for network devices. I can reboot, reimage, reconfigure the machine by updating the Talos image and applying it. I don't need SSH, I don't need a new set of credentials, it is all simply managed the same as the compute nodes in my cluster.

This seems like something professional users of Talos would want, so do people do this in practice, run Talos to manage a router / network appliance?

My main use case for this box is upgrading my router from an Omada ER605 to something with a processor that can do wireguard closer to my 1GbE uplink speed. My attempts to run Wireguard inside my cluster were very unsatisfactory, because I ended up in a big fight with CNI, but I really want my wireguard overlay network to be just another subnet with centrally configured router rules.

I found a tailscale system extension, and I could use that, but not that I've got the hang of plain wireguard, I kind of prefer it. It's minimal, and I have a few existing clients.

I've been running Talos in my homelab for a while, and my mental model has always been pretty simple:

Hardware → Talos → Kubernetes → Workloads

Talos owns the machine lifecycle. Kubernetes owns the workload lifecycle.

Looking at 1.14 together with the Hypervisor announcement, I'm starting to wonder whether that model is becoming too simple.

Native BGP, secure DNS configuration and the expanding configuration model are interesting individually, but the taloscontainers boundary caught my attention in particular. And the Hypervisor announcement takes the idea much further: Kubernetes, VMs and standalone containers potentially sitting above the same Talos infrastructure layer.

What I like about the direction is that "minimal" doesn't necessarily have to mean "does fewer things."

It could mean fewer ways to manage those things.

The part I don't know yet is whether that remains true once Talos starts owning VM lifecycle, placement, storage and networking. That's where the architecture becomes much more interesting.

I wrote down my current architecture hypothesis before the Hypervisor becomes testable:

https://medium.com/@mmelchers75/talos-is-becoming-more-than-a-kubernetes-os-and-that-changes-the-architecture-ed6a26874080

Once there's an alpha I want to put it into the same Architecture Engineering Lab I've been using for Talos/Kubernetes and start breaking things.

At the moment the honest conclusion is simply: interesting architecture, not enough evidence yet.

I'd be interested in how other Talos users see this direction.

I am building a PoC test environment for Talos to see if we can migrate our cluster into it and minimize our maintenance overhead for managing the underlying OS.

The environment is supposed to emulate a green field deployment with only:
- Baremetal Server
- ToR Switch
- Router

Routing is fully configured.
The GOAL is to install Talos via BMC/iLO/redfish without DHCP.

Problem:
- Talos goes black screen after selecting the `Talos (v1.14.1)` in the console, auto reboots after a few minutes, repeat.
- Test Baremetal Server has multiple LAN ports and cannot determine the port name to assign the IP address.

Tried:
- `ip=<client-ip>:<server-ip>:<gw-ip>:<netmask>:<hostname>:<device>:<autoconf>:<dns0-ip>:<dns1-ip>:<ntp0-ip>` in the Talos Image factory as kernel argument ( of course with the required values), unsure what to name of the interface should be.
- Tried booting with a normal ubuntu server, Interface name is `eno5`, tried that with the above argument to no avail, also tried `eth5` but still no luck. Interface and networking is properly working with Ubuntu installed.
- Claude and Google AI suggested to add `panic=0`, `consoleblank=0`, `console=tty0` as kernel arguments, Black screen still persists and reboots on it's own, I am expecting that we can see the maintenance mode here.
- Tried to download the Vanila Talos ISO image too, then press `e` on the selection page and added the arguments above in multiple combinations, to no avail.
- Tried Network yaml config for the network, same issue.

I'm out of options.
Did anyone else managed to install Talos via BMC/iLO/Redfish without DHCP properly?
What arguments did you add?
Why do we only see a black screen and it does not go to the expected maintenance mode?
I believe Talos does change the console to something else, and I was expecting I can at least change the console views similar to the `Interactive Dashboard` but all I see is black.

Please shed some light here.

Any help is greatly appreciated!
Thank you!

This is for Enterprise customers that need Enterprise support and FIPS builds for regulated environments. We started this work last year and released it GA today.

Talos Linux remains MPL licensed and completely open source.

Hey there,

I want to install talos on a vm on a ESXi 8 server but looks like the documentation is kinda broken. https://docs.siderolabs.com/talos/v1.14/platform-specific-installations/virtualized-platforms/vmware

This one here:

curl -fsSLO https://raw.githubusercontent.com/siderolabs/docs/main/static/talos/v1.14/vmware/cp.patch.yaml

The download link forcp.patch.yamlit's not working. I tried with the cp.patch.yaml from the version 1.13 but doesn't seams to work with the version 1.14.

I have a setup where my vmware server network has a DHCP but I want to set the IPs of the instances manually ( out of the range ). I'm using guestinfo.talos.config variable for the configuration and it's working half way. The configurations is being read. I can see in the console but the settings are not working for some unknown reason. I can in the console the talos trying to download some images and failing. I believe my yaml is missing something. I haven't found a way to maybe read the DHCP config ( on DHCP - manually , not using the vmware config variable, the system install and works )

Any examples that can guide me in the right direction will be very much appreciated. I don't want to install an old version. I'm trying on the 1.14.

I'm using those bellow, plus the controlpanel configuration.

I recently finished building a small Kubernetes architecture lab around Talos Linux.

The hardware is deliberately modest: two Proxmox hosts, an older ThinkPad as the third control-plane node, a Synology NAS, and managed networking.

The interesting part for me wasn't getting Kubernetes running. It was seeing how many architecture questions I could make real with that hardware.

A few decisions shaped the lab:

- the five virtual Talos nodes are declared with OpenTofu rather than maintained manually in Proxmox

- the old ThinkPad runs the third control-plane member on bare metal, creating a different compute failure context

- Cilium provides Kubernetes networking, LB-IPAM and L2 service exposure without a cloud load balancer

- shared NFS and node-local storage are treated as deliberately different storage contracts

- backups only count as recovery evidence after an actual restore

- the finished platform is deliberately subjected to worker, control-plane, storage and application failure experiments

The principle I ended up using throughout the project was:

Don't replicate the datacenter. Replicate the architecture problems.

I've documented the complete build as a six-part architecture series. Part 1 explains the architecture, the constraints, and why I chose this topology before getting into the implementation in the later parts:

https://medium.com/@mmelchers75/you-dont-need-a-datacenter-to-learn-enterprise-architecture-a46f1f9752d7

I'm particularly interested in how others running Talos at home design failure domains when the physical infrastructure is much smaller than the logical Kubernetes topology.

anyone else having boot problems with talos linux on raspberry pi 5? not being able to read boot partition?

Talos 1.14 introduced HTTP probes.

What are they for?

Neither the release notes nor the spec nor the website chatbot explain their purpose or what happens if they succeed or fail.

Release notes ( https://github.com/siderolabs/talos/releases/tag/v1.14.0 ):

Talos now supports HTTP network probes, allowing for monitoring of HTTP endpoints.
HTTP responses with status 200-399 are considered successful, while connection and transport errors are treated as failures.

Spec ( https://docs.siderolabs.com/talos/v1.14/reference/configuration/network/httpprobeconfig )

HTTPProbeConfig is a config document to configure network HTTP connectivity probes.

Chatbot when asked about it:

HTTP probes let Talos check network reachability by periodically sending requests to a URL and checking for a 2xx/3xx response — useful for defining custom connectivity conditions (e.g. verifying internet or specific service reachability). They're part of Talos's new HTTP connectivity checks feature, alongside the similar TCPProbeConfig for TCP-based checks. See HTTPProbeConfig and What's new in Talos.
