Kubernetes service doesn't load balance. Here is why 👇 By default, the kube-proxy component in Kubernetes uses iptables for routing requests. (Supports IPVS as well) We were curious about how it manages load balancing behind the scenes, and we discovered something interesting: a feature in iptables called 𝘀𝘁𝗮𝘁𝗶𝘀𝘁𝗶𝗰 𝗺𝗼𝗱𝗲 𝗿𝗮𝗻𝗱𝗼𝗺 𝗽𝗿𝗼𝗯𝗮𝗯𝗶𝗹𝗶𝘁𝘆. This feature is part of iptables and is used for packet filtering and network address translation. It allows you to create rules that match a specific percentage of packets at random. For example, we tested a service endpoint pointing to a three-pod deployment. It showed statistic mode random probability as 0.33 , essentially balancing the load across the three pods. It is more of a probabilistic traffic distribution, rather than actual load balancing. - It doesn't consider the actual load on the servers. - It doesn't guarantee an even distribution of traffic over time. - It doesn't maintain session persistence You might wonder, "Is it necessary to understand Kubernetes at this level?" The answer is Yes & No 😀 In one implementation, we encountered a major routing issue. By looking at the iptables rules, we ruled out any cluster configuration issues and pinpointed the problem. We cover many topics like these in our CKA course in bonus sections.

Kubernetes is an open source tool that helps you manage all the parts of your apps in containers. So if you have an app with a bunch of microservices, for example, Kubernetes lets you wrangle them more easily. In this handbook, Prince teaches you about pods, workflows, deployments, creating clusters, use cases, & lots more. https://lnkd.in/gTk_aaae

With Great Access Comes Great Responsibility! Access tokens are powerful - too powerful, if you don’t rein them in. Developer Advocate Andrea Chiarelli's deep dive into OAuth 2.0 explains how to keep those tokens on a tight leash using the Principle of Least Privilege. 👀 Learn how to: ✔️ Scope like a pro (no more scope=*) ✔️ Design granular permissions (e.g., orders:read, not just orders) ✔️ Validate tokens the right way, not just checking if they’re expired ‼️ Bonus: It includes a checklist you can actually use before you ship. 🔗 https://lnkd.in/e9Jacend

When Kubernetes first took off, everything started with one question: Where will your cluster live? No matter the size of your environment or the tools you used, every setup began with a host cluster. It was the foundation you couldn’t skip, until now. With our latest release, that dependency disappears. It’s a fully self-contained control plane that runs anywhere: in a CI pipeline, on a laptop, or on bare metal, giving teams a fast and portable way to start Kubernetes instantly. In this deep dive, Saiyam Pathak walks through how Standalone vCluster simplifies the entire stack, removing layers of setup, vendors, and overhead, and why it marks a new chapter in Kubernetes tenancy. 🎥 Watch the full video: https://lnkd.in/ghCQ59CP #Kubernetes #vCluster #CloudNative #PlatformEngineering #MultiTenancy

Why the OI4 was the odd one out in ContainerDays 25 At ContainerDays 2025 in Hamburg, the spotlight was on Kubernetes, DevOps, AI, ML, GoLang and cloud-native. OI4 stood apart. We brought industrial automation to a stage usually reserved for pure IT. What we showed: - The Software Defined Automation (SDA) project that connects operational technology with container and cloud ecosystems - Real industrial equipment on site to demonstrate the bridge between physical machines and containerized software - A clear path forward for combining standards, orchestration, and edge computing to make automation scalable and vendor-independent 👉 Read more here: https://lnkd.in/eaZYabhj

We're all about developer velocity. ⚡ Today, we're removing more friction from your workflow with two new Gemini CLI extensions! 1️⃣ Automate Deployment: What used to be a multi-step process is now a single /deploy command. Go straight from your local terminal to a live application on our serverless platform, Cloud Run. 2️⃣ Automate Security: Shift security left without slowing down. The /security:analyze command integrates comprehensive security analysis directly into your local repository or CI/CD pipeline, catching vulnerabilities before they become problems. Read how these new extensions are designed to make the path from idea to production as short and secure as possible → https://goo.gle/4nnNYi3
