In Kubernetes v1.35, we're introducing Extended Toleration Operators as an alpha feature. This enhancement adds Gt (Greater Than) and Lt (Less Than) operators to spec.tolerations, enabling threshold-based scheduling decisions that unlock new possibilities for SLA-based placement, cost optimization, and performance-aware workload distribution.

If you're running PostgreSQL on Kubernetes, chances are you've used Bitnami's popular Helm charts. They've been a go-to for many, but a significant change is on the horizon. As outlined in this GitHub issue, Bitnami is moving its production-ready charts and images to a commercial offering. For those of us who rely on and advocate for open-source solutions, this means it's time to find a robust alternative.

The Kubernetes story is one I hear often. Teams adopt K8s expecting operational simplicity, only to discover they've traded application complexity for infrastructure complexity. For a solo founder focused on content creation, maintaining a Kubernetes cluster was simply the wrong trade-off.

This article is about the patterns that actually work when you're managing real databases in Kubernetes, not hello-world demos: when your boss says "everything should be containerized" but your databases laugh in the face of ephemeral pods, and when GitOps meets a 200GB production database that absolutely cannot lose a single transaction.

Operators make life easier, but they are not always an option. In this post, I'll walk through a practical way to deploy large language models on OpenShift without relying on the OpenShift AI or NVIDIA operators. The approach uses llama.cpp as a lightweight runtime engine and runs a quantized GGUF model to enable efficient inference with minimal dependencies.

This article explains how Cosign, Kyverno, and Harbor can work together to enforce image signature verification in Kubernetes. The approach is well-suited for enterprise environments with private registries, custom TLS certificates, and restricted access to public transparency logs.

Jenkins might feel like legacy tech, but it's still powering CI/CD at thousands of companies. Instead of ripping it out, here's how to modernize it with Kubernetes — solving cost tracking, resource isolation, and scalability problems along the way.

This blog aims to provide a practical example of how core tools like Kubernetes, Terraform, and DevContainers can be combined to build a local data platform in a structured and maintainable way.

Netfence runs as a daemon on your VM/container hosts and automatically injects eBPF filter programs into cgroups and network interfaces, with a built-in DNS server that resolves allowed domains and populates the IP allowlist.

A lightweight, extensible Kubernetes Operator that probes any endpoint—HTTP/JSON, TCP, DNS, ICMP, Trino, OpenSearch, and more—and routes alerts to Slack or e-mail with a simple Custom Resource.

Argo CD Diff Preview is a tool that renders the diff between two branches in a Git repository. It is designed to render manifests generated by Argo CD, providing a clear and concise view of the changes between two branches. It operates similarly to Atlantis for Terraform, creating a plan that outlines the proposed changes.
