Critical Unauthenticated Remote Code Execution Vulnerabilities in Ingress NGINX (wiz.io)
Wiz Research discovered CVE-2025-1097, CVE-2025-1098, CVE-2025-24514 and CVE-2025-1974, a series of unauthenticated Remote Code Execution vulnerabilities in Ingress NGINX Controller for Kubernetes dubbed #IngressNightmare. Exploitation of these vulnerabilities leads to unauthorized access to all secrets stored across all namespaces in the Kubernetes cluster by attackers, which can result in cluster takeover.  This attack vector has been assigned a CVSS v3.1 base score of 9.8.

Understanding DNS Resolution on Linux and Kubernetes (jpetazzo.github.io)
I recently investigated a warning message on Kubernetes that said: DNSConfigForming ... Nameserver limits were exceeded, some nameservers have been omitted. This was technically a Kubernetes event with type: Warning, and these usually indicate that there’s something wrong, so I wanted to investigate it.

Kubernetes Home – what do you do if your ISP changes your IP addresses? (priv.no)
In my last blog post I described external-DNS, which is a way to have Kubernetes create and update DNS entries for its services. But as I mentioned, it got me thinking a bit on ways to extend this concept to handle other external aspects of my Kubernetes environment.

Yoke: Infrastructure as code, but actually (xeiaso.net)
Yoke is a project that takes this basic idea to the next level. With Yoke, you write your infrastructure definitions in Go or Rust, compile it to WebAssembly, and then you take input and output Kubernetes manifests that get applied to the cluster.

The Kubernetes Mirage: When Scaling Up Becomes Your Greatest Downfall (medium.com)
It’s 3 AM when your phone erupts. Production is down. Your “fault-tolerant” Kubernetes cluster has become a digital Ouija board — pods vanishing, nodes collapsing, logs whispering nonsense. By sunrise, you’ve burned a lifetime supply of cloud credits and aged three years. Welcome to the Kubernetes paradox: the tool meant to save you now owns you.

Replace Docker Compose with Quadlet and Systemd (matduggan.com)
So for years I've used Docker Compose as my stepping stone to k8s. If the project is small, or mostly for my own consumption OR if the business requirements don't really support the complexity of k8s, I use Compose.

Ask HN: Is software engineering just patching APIs and wrangling Kubernetes? (ycombinator.com)
Does anyone else feel disillusioned with the modern software engineering job? It often feels like it's just stitching together APIs, wrestling with React state, and managing Kubernetes clusters rather than building something truly exciting.

So you wanna write Kubernetes controllers? (ahmet.im)
Any company using Kubernetes eventually starts looking into developing their custom controllers. After all, what’s not to like about being able to provision resources with declarative configuration: Control loops are fun, and Kubebuilder makes it extremely easy to get started with writing Kubernetes controllers. Next thing you know, customers in production are relying on the buggy controller you developed without understanding how to design idiomatic APIs and building reliable controllers.

Zork: The Great Inner Workings (2020) (medium.com)
Roughly a year ago, during the summer of 2019, I got an idea. I was setting up a Kubernetes cluster, and as I usually do, I set up a mock web server using Nginx to test out Ingress, SSL, and domain settings. Then it hit me, wouldn’t it be great if instead of a boring webserver I would use a web game as my testing service and then leave it in the cluster as sort of a calling card.
