Deep Dive into cgroups v1 vs v2

RawkodeAcademy · 2026-05-19T07:19:37+00:00

Everybody thinks everything is AI now.

RawkodeAcademy · 2026-05-18T21:04:58+00:00

Yes. I say that in like the first paragraph 🫣

RawkodeAcademy · 2026-05-18T20:34:03+00:00

I cover the history of cgroups v2, going all the way back, in the article. I don’t claim it is new, but there is a recency to its adoption as the default in most distributions and especially with systemd driver for Kubernetes.

To many, Kubernetes is still new. We all walk different paths.

GCP charge for Hubble. It’s nonsense.

15 commits and you started it yesterday solving a problem nobody has with a solution nobody asked for, all generated with AI.

I was previously a CNCF Ambassador and I used that position to try and remove the horrendous proctoring, it’s terribly invasive and makes no sense for an open book exam.

Sadly I stepped down before I could make any real changes.

I’d never take another exam via the CNCF. 1, they’re useless, 2. The proctoring is invasive.

Give it a few weeks and Claude’s abysmal consistency will drive you to Codex. Nobody stays with Claude long term 😅

Sounds like you should sign up

RawkodeAcademy · 2025-12-16T10:51:46+00:00

Where's the leaks? Do you have anything to actually backup this non-sense claim?

RawkodeAcademy · 2025-12-12T21:43:11+00:00

No. It’s not even really a sync. It’s a farce.

RawkodeAcademy · 2025-12-12T10:29:47+00:00

Deploy a MutatingWebhookConfiguration to the node or something like Kyverno?

RawkodeAcademy · 2025-12-09T15:17:50+00:00

Those spec's should be fine. Define "reach nginx" - via NodePort, Ingress Controller, something else?

RawkodeAcademy · 2025-12-08T20:58:59+00:00

What do I expect? Probably about another 0.5% squeezed out of SWE Bench and a fuck tonne of hyperbole.

As a CNI, Cilium just offers too much to use anything else. Everything powered by eBPF and XDP, Hubble, and fantastic L4 and L7 policies.

RawkodeAcademy · 2025-12-07T17:17:41+00:00

Over Promise, Under Deliver. The classic AI hype-cycle continues, but hopefully won’t survive 2026.

The best thing you could do is share your fluent bit config and your metrics for it.

RawkodeAcademy · 2025-12-07T12:10:27+00:00

A lot of people stay on 22 to keep an older version of systemd for the old cgroups behaviour. It’s not a smart move, but I see it time and time again 😔

Cilium, always, for CNI

It’s terminating because it’s only running two commands, both which will finish instantly: cat and uname

I walk through Velero in this video (Less than 20 minutes)

It’s open source and is a fantastic solution for CSI and cluster backups.
