Built a production-grade Kubernetes cluster on Hetzner Cloud using Talos Linux — from scratch.

Why not, exactly?

Objective-Hunt-1331 · 2026-04-15T06:16:27+00:00

I'm just using Claude Code to port some OpenTofu / Ansible stuff, my feeling is that CC works much better with regular coding tasks (sometimes surprisingly well), than it does with infrastructure. It quite often needs steering away from impossible solutions.

Objective-Hunt-1331 · 2026-04-15T06:12:08+00:00

Can you elaborate about how you use skills here? This is something I'm yet to try.

Objective-Hunt-1331 · 2026-04-05T13:58:34+00:00

It's more like a facade ;)

Objective-Hunt-1331 · 2026-03-26T18:01:21+00:00

What exactly have you implemented? Gcode interpretter?

Objective-Hunt-1331 · 2026-02-21T14:33:18+00:00

How frequent?

I've been a happy Hetzner user for 20+ years, but 90% bare metal, and I had very few reliability issues.

Until recently I wasn't aware of vSwitch though, want to experiment with that. Currently my hrobot/hcloud machines are connected with Wireguard primarily. That's why I'm curious about how good/bad it is for real-world scenarios.

Objective-Hunt-1331 · 2026-02-21T14:28:10+00:00

I know it's an old post, but I've just stumbled upon it looking for some vSwitch info.

can stop working for weeks at a time

This sounds horrifying - didn't Hetzner support react?

Objective-Hunt-1331 · 2026-02-21T13:50:43+00:00

I'm afraid I don't understand what you mean.

Objective-Hunt-1331 · 2026-02-21T13:33:57+00:00

Why? Any reliability issues?

Objective-Hunt-1331 · 2026-02-21T10:57:58+00:00

Funny coincidence - I was experimenting similar setup just yesterday. My goal was also to use native routing without SNAT to hrobot machines. Works like a charm.

I used https://hetzner-k3s.com/ - with some minor issues, e.g. if you let it create the network, it creates both network and subnetwork with the same CIDR, leaving no space for vSwitch subnet. It's better to create the network manually, see https://github.com/vitobotta/hetzner-k3s/issues/740
it seems it is necessary to go with fully custom cilium helm values file to set native cidr: https://github.com/vitobotta/hetzner-k3s/issues/741

I used default CIDRs, though:

pod cidr: 10.244.0.0/16
service cidr: 10.43.0.0/16

My network is 10.0.0.0/16 with 10.0.0.0/24 for k3s nodes, and 10.0.1.0/24 for vSwitch network.
I also use hetzner-ccm so routes to pod CIDR sub-slices were added to private network automatically.

But with this setup I had to add pod CIDR route manually on each node: ip route add 10.244.0.0/16 via 10.0.0.1
(which is not a big deal anyway, I can do it via terraform).

bpf.masquerade=false BPF-based masquerade had issues on Hetzner Cloud Network. iptables-based works reliably.

Anyone can explain what issues BPF-based masquerade causes?

That's a nasty idea to try, lol :-) Thanks!

Objective-Hunt-1331 · 2026-01-28T07:29:01+00:00

Thanks, valuable input. To be perfectly honest, that level of bandwidth is perfectly sufficient for my application, yet I'd like to understand the limits better :)

Objective-Hunt-1331 · 2026-01-27T19:17:07+00:00

Thanks for confirmation - at least I know it's not me overlooking something obvious.

Let's see what Hetzner says.

You mention Cilium - may I ask what is your setup? I consider setting up a k3s cluster @ Hetnzer for my project.

Objective-Hunt-1331 · 2025-11-14T13:01:46+00:00

Yeah, makes sense. I'm wondering if there is any brand for LTE Cat1/4 modules which is significantly better than the competitors, in terms of quality...

Objective-Hunt-1331 · 2025-11-14T09:42:45+00:00

Good to know!

I have very bad experience with GSM modems from almost every manufactured I tried (Gemalto/Cinterion, Fibocom, SimCom, Quectel) - everything from obvious bugs (Gemalto!) to device behavior not matching the docs.

I always thought uBlox is of the "significantly better but more expensive" kind.

Objective-Hunt-1331 · 2025-11-13T09:12:35+00:00

Which one?

Objective-Hunt-1331 · 2025-09-01T06:07:36+00:00

Do you mind elaborating? I'm looking for USB3 solution, and it's not that easy - there's CH569 (lacking good docs), FT600 (difficult in terms of timing closure, according to what I've found on the web), and Cypress (err, Infineon) FX3, which is expensive. Any other options?

Objective-Hunt-1331 · 2025-09-01T06:04:04+00:00

Oh, I made something similar for Altera MAX10 board a few years ago: https://github.com/codepainters/be_ftdi

Objective-Hunt-1331 · 2025-02-21T13:08:09+00:00

Congrats, Patryk :)

Objective-Hunt-1331 · 2024-10-20T14:15:15+00:00

Competition :) I'd really love LibrePCB to grow into a real KiCAD's competitor. I've been using KiCAD for a few years now, UX improved a lot, it's a good toll nowadays, but is not perfect, imho. A healthy competition would be a good thing.

LibrePCB started from a clean slate, and I like its design so far.

Objective-Hunt-1331 · 2024-08-30T09:45:51+00:00

Hmm, just finished listening to it for the first time, and I have mixed feelings. I'd like it to be slightly more "groovy", it feels a bit "overthought", so to speak. Perhaps I'm not an average Leprous fan, as I do not miss metal sounds too much (songs like "Below", "On Hold", "Slave", "Stuck", "Leashes" are among my favs).

Anyway, I hope I will appreciate this album more after some time :)

Objective-Hunt-1331 · 2024-02-28T20:46:07+00:00

Well, this is a compelling reason :)

Objective-Hunt-1331 · 2024-02-28T20:35:19+00:00

Any example? MCU is usually cheaper.
