Nope, but that’s a good idea for another challenge 😃

You are on the right path, but it’s not an authz trick. :)

I can neither confirm nor deny that there is a high chance it is. :)

Did you know that pods can become "invisible"?

Test your Kubernetes knowledge by finding an invisible pod in this challenge: labs.iximiuz.com/challenges/....

No hints, no solutions. Prepare for a tough one.

Thanks to the fantastic @averagemarcus.bsky.social for this gem.

These past couple days I've been working on a new side project: github.com/sagikazarma...

It allows running slash commands from GitHub issues and pull requests.

Feedback welcome! :)

I've been using devenv.sh in my Flake envs for a while (proof: github.com/search?q=ow...**%2Fflake.nix+devenv&type=code), but I initially avoided their CLI.

However, I've realized that I don't use the advantages of Flakes, and their CLI offers a much better experience.

By the way, if anyone has a viable solution, I'm all ears.

So, if I haven't responded to an issue or reviewed a PR, it's not because I don't care, and maybe not even because I lack the time (though that's often true), but simply because I don't see it.

If it's important, please keep pinging me in issues or reach out via alternative channels.

I've just deleted about 5,000 GitHub email notifications that piled up over the last two months.

That's over 500 emails a week, more than 50 a day.

Admittedly, not all demand my attention, but just sifting through them takes considerable time.

Git is central to modern software and platform engineering, making it and its ecosystem accessible to everyone is crucial.

I’m glad to see GitHub alternatives like @gitea.com, as they help democratize the ecosystem.

Played around with @golang iterators today: github.com/sagikazarma...

I'm still undecided about how I feel about them.

I like the concept, but I'm concerned it might hurt readability more than it helps.

I'm also a bit disappointed to see how iterators are so much more powerful in other languages.

Testing mutating and validating admission policies can be challenging, especially when dealing with complex policies.

Here's an online tool that can help: playcel.undistro.io/

Kubernetes 1.34 brings Mutating Admission Policy to beta!

To celebrate the occasion, I wrote a comprehensive tutorial on admission control: labs.iximiuz.com/tutorials/k...

Check it out if you're interested in a deep dive into Kubernetes admission control.

Kubernetes 1.34 has just been released!

If you're eager to explore the new features, my Kubernetes the Hard Way playground is already upgraded:

Container runtime, OCI runtime, runtime handler, RuntimeClass

What exactly do all these terms mean, and how are they connected?

Cool! Let’s chat somewhere about the details!

Márk Sági-Kazár @sagikazarmark.com · Aug 19

Anything Kubernetes I guess?

Both of us have been digging around Kubernetes internals lately, so I’m sure we can find something.

My focus lately is explaining how Kubernetes works under the hood from kubectl to how containers run and what’s happening in between.

Mutating admission policies will graduate to beta in a few weeks: github.com/orgs/kubern...

If you find mutating admission webhooks challenging, even for simple mutations, this will be a game changer for you.

Another great Kubernetes tool I found recently:
kaniuse.gerome.dev/

It allows you to track which features are in which stage and in which Kubernetes version.

As a content author, I especially appreciate the historical information.

Although some ingress controllers can be set to use Service ClusterIP or NodePort, most resolve endpoints and route traffic directly to pods.

This approach grants the ingress gateway greater control over traffic routing and enables advanced features.

I just found kubespec.dev/ and I love it!

It's a great way to quickly look up the syntax for Kubernetes objects.
