🎯 Woodpecker: Open-source red teaming for security

Read. Think. Ship. Repeat. You've got a universe of tools to explore.

k0s, the streamlined Kubernetes flavor pioneered by the CNCF Sandbox, strips it down to one slick binary. It's tailor-made for edge AI, shedding the bulky baggage. Unlike K3s, k0s thrives on meager resources, sipping energy while skipping the tangled installation dance. Just 1-2 GB of RAM, and you're off to the races.

Woodpecker takes on the dirty work of red teaming for AI, Kubernetes, and APIs. It tackles over half of the OWASP Top 10 threats without breaking a sweat. Find it free on GitHub, spreading top-notch security testing like free candy.

CVE-2025-47933 in Argo CD shreds security and hands injected JavaScript the keys to your Kubernetes kingdom. With a terrifying CVSS score of 9.1, this one's no joke. Patch it, yesterday!

Docker's MCP Catalog and Toolkit bust myths and solve setup headaches, smoothing out AI agent development with snug, secure containers. With heavy-hitter partners like Stripe, Elastic, and Heroku on board, developers now revel in one-click connections through Docker Desktop. Integration nightmares and security fears? Poof—gone.

Kubecost hooks into GKE and GCP, serving up sharp, detailed cost reports by namespace. It even spills the tea on out-of-cluster expenses. A dream for FinOps wizards.

A wild 440% spike in Kubernetes vulnerabilities over five years calls for open-source security tools that actually get the job done. Still, half of the organizations feel like they're playing catch-up trying to lock it down. Enter tools like Falco and Istio. Falco sniffs out runtime anomalies while Istio armors services with TLS. Together, they highlight why dynamic threat detection isn't just a luxury—it's a necessity.

KubeVirt promises the glitzy dream: running VMs in Kubernetes. With Red Hat and friends fanning the flame, it seems poised for greatness. But hold your applause—it's not yet a production powerhouse. Advanced VM management features? Missing in action. Switching to KubeVirt isn't just a hop; it's a leap of faith. Tooling, skills—the whole shebang needs an upgrade. A hefty ask for its freshman stage.

Orca Research Pod discovered two bugs in kro that could allow an attacker to introduce a malicious CustomResourceDefinition (CRD). Kro is an open-source project enabling custom Kubernetes APIs using ResourceGraphDefinition resources. These vulnerabilities could lead to a confused deputy scenario where unauthorized actions are performed.

Kubernetes transformed from an obscure tech into a backbone for cloud-native AI projects. Today, Google Cloud takes the crown for effortlessly scaling AI models with GKE. Together, Cloud Run and Kubernetes curb AI inference expenses. The secret sauce? On-the-fly GPU access and serverless wizardry that let enterprises nimbly dance through their digital demands.

Kubernetes' Master Node is the cluster's brain. The API Server? Think of it as the front door, shrewdly dispatching developer requests like a bouncer with a clipboard.

Kubernetes v1.33 crushes it for AI/ML workloads with slick Dynamic Resource Allocation. Your GPU headaches? Gone. It's nimble, modular, and ready to scale. Plus, with topology-aware routing now in the spotlight, Kubernetes slashes network latency and trims cloud expenses by favoring the nearest options. Perfect for those massive AI inference marathons.

Abhishek Munagekar from the Search Infrastructure Team at Mercari manages several Elasticsearch clusters on Kubernetes using the Elastic Cloud on Kubernetes (ECK) Operator. The team embarked on an upgrade project to leverage advancements in newer ECK operator versions. By implementing a custom side-by-side upgrade approach and modifying the ECK operator to support dual versions, the team was able to minimize risks and ensure a more resilient upgrade process for their critical infrastructure.

Running a Kubernetes-native MQTT broker with Eclipse Mosquitto cuts downtime to a mere 5 seconds. Compare that to the usual 5-minute snooze. This feat involves Traefik sorcery and a custom failover rig. Uninterrupted message flow? Check. Real-time state? Handled with message bridges that practically dance across the network.

Modular monoliths risk turning into messy "big balls of mud" when developers overdo shortcuts or tangle the code. Go modular-first and be ready to spot stealthy dependencies lurking in the corners. Skip the quick fixes—they're overrated.

The EKS MCP server hands AI code assistants, like Q Developer CLI, the keys to a streamlined Kubernetes kingdom. App development? Now lightning fast. With LLMs tapping into real-time context, AI flexes its muscles in the wild world of Kubernetes ops and troubleshooting.

Hardcoding secrets is a ticking time bomb. Instead, reach for centralized tools like HashiCorp Vault; they'll guard your secrets like a vault should. Automate secret rotation so your credentials don't gather dust, and log everything to keep tabs on who does what. Devtron makes it a breeze with its Kubernetes-native magic, slashing the hassle and risk in CI/CD like a ninja.

Kubernetes on Debian just got its act together. The team axed the messy vendoring, shrunk the tarball bulk by over half, and tidied up dependency chaos. Now every dependency snuggles into Debian nicely, kicking out those pesky proprietary blobs. This means a secure, policy-friendly package and—drumroll—kubectl finally steps into the present. The community can breathe a little easier now.

YISP is a Lisp-inspired evaluation engine for YAML – useful for generating Kubernetes manifests, configuration files, and more.

Did you know that Netflix engineers adopted a novel chaos engineering tool they call "ChAP" (Chaos Automation Platform) to continuously improve application reliability? By proactively injecting failures into their distributed systems, Netflix can monitor how services handle unexpected outages in real-time conditions. They discovered that 20% of their microservices were initially unable to gracefully handle injected faults, which led to a targeted refactoring that improved system resilience. This approach gives them an edge by identifying potential weak points before users ever experience them.
