Amid all the noise about dockershim, one thing got lost: the everyday workflow of building an image with Docker and running it on Kubernetes never changed. Docker is still an excellent build tool, Kubernetes still runs OCI images, and on Ubuntu the loop is clean. Here it is end to end. 1. A build-friendly Dockerfile Multi-stage keeps the runtime image small and the attack surface low — this matters more on Kubernetes, where you pull the image onto every node that schedules the pod: # build stage FROM golang:1.22 AS build WORKDIR /src COPY go.* ./ RUN go mod download COPY . . RUN CGO_ENABLED = 0 go build -o /out/api ./cmd/api # runtime stage — distroless, no shell, tiny FROM gcr.io/distroless/static:nonroot COPY --from=build /out/api /api USER nonroot:nonroot EXPOSE 8080 ENTRYPOINT ["/api"] 2. Build and push with Docker on Ubuntu Use buildx (bundled with modern Docker) so you can build multi-arch — worth it if any nodes are arm64: docker buildx build \ --platform linux/amd64,linux/arm64 \ -t registry.example.com/api:1.4.2 \ --push . Tag with an immutable version, never rely on :latest . Kubernetes caches images per node; :latest makes "which build is actually running?" unanswerable and breaks rollbacks. 3. A deployment that behaves in production apiVersion : apps/v1 kind : Deployment metadata : name : api spec : replicas : 3 selector : { matchLabels : { app : api } } template : metadata : { labels : { app : api } } spec : containers : - name : api image : registry.example.com/api:1.4.2 # the exact tag you pushed imagePullPolicy : IfNotPresent ports : [{ containerPort : 8080 }] resources : requests : { cpu : " 100m" , memory : " 128Mi" } limits : { memory : " 256Mi" } readinessProbe : httpGet : { path : /healthz , port : 8080 } initialDelaySeconds : 3 livenessProbe : httpGet : { path : /healthz , port : 8080 } initialDelaySeconds : 10 The readinessProbe is the piece people skip and regret: without it, Kubernetes sends traffic to a pod before your app is listening, and

David Risher insists that Lyft has lowered its prices and that customers who only check his competitor’s app are “leaving money on the table.”

A new technical analysis published by the Cloud Native Computing Foundation (CNCF) argues that the future of agentic AI will be built not on entirely new infrastructure, but on the mature cloud-native ecosystem that already powers modern distributed applications By Craig Risi

Uber explained how it keeps its OpenSearch deployments running during a zone outage. It does this by using OpenSearch's built-in shard allocation and its own isolation-group system, which relies on the Odin container orchestration platform. This way, it maintains both query and ingestion capabilities. By Claudio Masolo

From Zero to a Working EKS Pipeline: Terraform, Ansible, and GitLab CI/CD (and Everything That Broke Along the Way) I recently built an end-to-end deployment pipeline on AWS EKS using Terraform for infrastructure, Ansible for configuration, and GitLab CI/CD to tie it all together. On paper, that sentence sounds clean. In practice, it took several rounds of "why is this failing" before it actually worked. This post is not a "here's how EKS works" tutorial. There are plenty of those. This is the version with the failures left in, the quota limits, the IAM permission walls, the pods that wouldn't schedule, and the resources that refused to die. If you're building something similar, I'm hoping this saves you a few hours of confused Googling. Repo: gitlab.com/nenyeonyema/terraform-eks-ansible-cicd What I Was Building The goal was a full IaC-driven pipeline: Terraform to provision the EKS cluster and supporting AWS infrastructure (VPC, node groups, IAM roles) Ansible to handle configuration tasks on top of the provisioned infrastructure GitLab CI/CD to automate the whole thing — plan, apply, configure, deploy — on every push Simple enough in theory. Four separate blockers said otherwise. Blocker #1: Free Tier ASG Restrictions The first wall I hit was with the Auto Scaling Group for my EKS node group. AWS Free Tier limits how much compute you can provision, and my initial node group sizing quietly ran into those limits — the kind of failure that doesn't always throw an obvious, single-line error. Fix: I resized the node group to stay within Free Tier boundaries and got explicit about instance types and desired/min/max capacity in Terraform, instead of leaving Auto Scaling to make assumptions I couldn't afford. Lesson: If you're building on Free Tier, hardcode your capacity expectations early. Don't let the defaults surprise you later. Blocker #2: EKS Private Endpoint Access By default, EKS clusters can be configured with private-only API server endpoint access. That's grea

How an unexpected regional constraint forced us to deeply understand Azure GPU VM families, naming conventions, and workload fit. Introduction As architects, we often assume that infrastructure decisions are straightforward: "The workload is already running successfully in Region A. Let's deploy the same Kubernetes workload in Region B." That's exactly what we thought. Our workload consisted of a Visual Element Detection (VED) service hosted on Kubernetes. The application uses a PyTorch model to analyze images and detect various visual elements in an image file. The service was already running successfully on a node pool backed by Azure's NVads_A10_v5 GPU VMs. Then we hit an unexpected challenge. The target region did not offer NVads_A10_v5 instances. What looked like a simple deployment exercise became a deep dive into Azure GPU virtual machine families, GPU architectures, VM naming conventions, and workload characteristics. This article shares what I learned in the hope that it helps others who find themselves evaluating Azure GPU SKUs for AI inference workloads. I am relatively new to the world of MLOps, Model deployments, GPU Workloads etc and equally interested and excited to learn more on this front. The Workload Before discussing VM selection, let's understand the workload characteristics: Model Type : PyTorch Model Size : less than 200 MB (.pth) Image Resolution : ~2000 x 2000 Expected Throughput : 5-7 requests/sec Platform : AKS (Kubernetes) Workload Type : Inference only This is important because GPU sizing should always start from the workload and not from the VM catalog. Step 1: Understanding Azure GPU VM Families Many engineers first encounter Azure GPU machines through names like: NV12s_v3 NV6ads_A10_v5 NC4as_T4_v3 ND96isr_H100_v5 The naming can be intimidating. The first breakthrough was understanding that Azure organizes GPU VMs into three primary families: N-Series ├── NV ├── NC └── ND NV Series – Visualization and Graphics NV-series VMs are designe

Every DevOps engineer has done this dance: you've got a chunk of YAML or a Terraform file that looks right, something's rejecting it, and you want a fast sanity check. So you paste it into some random online validator — and a small voice asks, wait, where did that config just go? That config often has structure, comments, sometimes internal hostnames or resource names in it. Pasting infrastructure definitions into an unknown server is a habit worth breaking. So I built a set of validators that never send your config anywhere — they run entirely in your browser. What they are Free, browser-based validators for the formats DevOps folks paste-and-pray most: YAML — catches the indentation and structure errors that make Kubernetes and CI configs fail with cryptic messages Kubernetes manifests — schema-aware checks beyond "is it valid YAML," so you catch the wrong apiVersion or a misplaced field before kubectl apply does Terraform / HCL — structural validation for the syntax slips that terraform validate flags only after you've context-switched away The one design decision that matters 100% client-side. No upload, no signup, no server round-trip. Your config is parsed by JavaScript running in your own tab — it never leaves your machine. You can literally open dev-tools, watch the network panel, and see nothing go out. Turn off your wifi and they still work. This isn't a privacy gimmick — it's the correct architecture for a tool that handles infrastructure definitions. A validator has no business seeing your config on a server it doesn't need to. Why I bother Two reasons, honestly. One: I kept wanting this exact thing and kept not trusting the options. The nth time I hesitated before pasting a manifest into a stranger's website, I decided to just build the version I'd trust. Two: fast feedback loops are the whole game in this job. The gap between "save the file" and "find out it's malformed" is pure friction — and the tighter that loop, the less of your working memory it b

Uber Chief Product Officer Sachin Kansal walks TechCrunch through the company's financial-services ambitions, its increasingly complicated relationship with Waymo, its new AV Labs data operation, and how AI is starting to show up in ways riders and drivers will actually notice.

Washington D.C. has become a battleground for Uber and Waymo's competing views.

Python is an excellent language for automating cloud infrastructure, but the official Kubernetes Python client leaves developers with an important architectural decision: Where should Kubernetes manifests live? Should they be constructed directly with Python objects? Embedded as multiline strings? Or stored as external files and rendered at runtime? Each approach works, but they have very different implications for readability, maintainability, and long-term operational cost. The key is recognizing that deployment logic and platform configuration evolve on different lifecycles. Your deployment code, the part that authenticates to Kubernetes, renders templates, and applies resources, may remain unchanged for months. Your manifests, however, often change weekly as applications evolve, resource limits are tuned, cloud-provider annotations are added, or networking requirements change. When those two concerns are tightly coupled, even a configuration, only change forces you to modify, test, and redeploy the delivery or application code itself. Over time, this increases maintenance costs, slows platform changes, and makes configuration drift and production mistakes more likely. This is a familiar software engineering principle: separate concerns that evolve independently. The same thinking that keeps application configuration separate from executable code also applies to Kubernetes manifests. Treating manifests as first-class configuration artifacts allows them to evolve independently from the Python code that delivers them. In this article we'll compare three ways of deploying Kubernetes resources with the official kubernetes-python-client , ranging from tightly coupled implementations to a design that cleanly separates deployment logic from platform configuration. The Landscape at a Glance The comparison below assumes a common application deployment scenario, where the desired state is largely known ahead of time. Controllers and Operators have fundamentally different r

Welcome back to TechCrunch Mobility, your hub for the future of transportation and now, more than ever, how AI is playing a part.

The status of the controller As of March 2026, the Kubernetes SIG Network stopped maintaining ingress-nginx. That is the controller a lot of clusters have been running for years. A CNCF blog post published July 9 walks operators through the state of play. The headline for anyone still on it is short: unpatched CVEs, and no more feature work. The post names two operational risks explicitly. New security issues will not receive upstream fixes. Feature updates and community support have stopped. If your ingress plane is a piece of infrastructure you have not touched in a while, this is the reason to pull it up in this quarter's planning doc. What it means at 3am An ingress controller sits between the internet and your services. When it drops a request, you find out from your users. When it takes a CVE and no one is patching, you find out from a scanner or from a report. Neither is a good discovery path. The controller also carries the exact set of annotations, TLS defaults and rewrite rules your workloads rely on. Nothing about a retirement changes the version you have in production today, so the immediate blast radius is zero. The risk is on the calendar, not on the pager. That is the kind of risk teams reliably defer until a scanner flags an unpatched CVE. The two paths CNCF lays out The post frames the choice as a fork. Path A is a lateral swap to another Ingress controller. The example named is Contour, described in the post as Envoy-based. This keeps you on the Ingress API and mostly moves the problem of who is patching. Path B is modernization to the Gateway API, described in the post as the upstream-backed successor to Ingress. The CNCF post points at ingress2gateway to automate the translation, and recommends an incremental rollout: run the new plane in parallel and move non-critical workloads first. The stopgap version is a mix. Adopt Contour to buy time on maintained code, then schedule the Gateway API move on your own calendar rather than under duress. What

A platform is a collaboration system: platform teams depend on application teams, and both need shared standards. Engineers trust a platform through its predictable behavior, not its features. Being an engineer is about problem-solving and being passionate about it. And being an engineer means sharing your passion for problem-solving. By Ben Linders

The Kubernetes community has introduced a framework for integrating AI into open-source maintainership, emphasising human accountability in code quality and oversight. AI tools may streamline workflows, but ultimate responsibility lies with human maintainers. The framework requires disclosure of AI usage in contributions and prohibits AI-generated commit messages.

Bạn sẽ học gì Sau bài này, bạn sẽ tự tay đưa một app từ số 0 (một thư mục trống) đến chạy được bên trong một cluster Kubernetes chạy trên máy của bạn . Cụ thể: Viết một app Todo API nhỏ bằng Node.js + Express. Đóng gói (container hoá) nó thành một Docker image. Tạo một cluster Kubernetes local bằng kind . Deploy app bằng file YAML "thật" (không dùng lệnh tắt) để hiểu Kubernetes vận hành thế nào. Truy cập app đang chạy trong cluster từ máy của bạn. Đây là Part 1 trong series "DevOps 101 — Học K8s, Helm, ArgoCD từ số 0" .

Developers love building things. Sometimes the hardest part isn't writing code—it's organizing data. Over the past few months, I've been building a large SVG library containing more than 180,000 vector files. At first, I assumed collecting the files would be the biggest challenge. I was wrong. The real challenge was organizing them. The Duplicate Problem Once a collection reaches hundreds of thousands of files, duplicates become unavoidable. Different sources often contain identical icons with different filenames. For example: facebook.svg facebook-logo.svg facebook-icon.svg facebook-black.svg facebook-circle.svg Some of these are genuine variations. Others are simply duplicates from different icon packs. Automatically detecting the difference isn't always easy. Collections Instead of Files Instead of treating every SVG as an individual page, I decided to build everything around collections. Examples include: Facebook Docker Kubernetes Payment Icons Weather Icons Medical Icons Programming Languages Each collection groups similar SVGs together, making browsing much easier than searching individual files. Keeping Search Engines Happy One interesting problem appeared during development. Should every individual SVG page be indexed? After experimenting with different structures, I chose a different approach. Only complete, content-rich collections are indexed. Individual SVG pages remain accessible but are excluded from search engine indexes. This avoids creating hundreds of thousands of thin pages while allowing search engines to focus on pages that actually provide value. Automation Managing thousands of collections manually isn't realistic. Several background scripts now automate most repetitive tasks: Collection descriptions Meta titles Meta descriptions FAQ generation Sitemap updates Controlled indexing This allows the library to continue growing without requiring manual editing for every collection. Data Cleanup One task I underestimated was cleanup. Large datasets

Originally published on DevToolHub . Helm 4 shipped in November 2025. Eight months later, most teams are still running Helm 3 in production CI/CD because it works. But Helm 3's final feature release lands September 9, 2026, and security patches stop completely on February 10, 2027. This helm 4 migration is simpler than it looks. Your charts don't need rewriting — Helm 3 Chart API v2 charts are fully compatible with Helm 4. But the automation around Helm has four real breaking points that fail silently if you don't know where to look. [IMAGE: articles/images/2026-07-05-helm-4-migration-guide-featured.png | alt: "helm 4 migration flow from Helm 3 to Helm 4 upgrade path"] Why This Helm 4 Migration Matters Now The EOL timeline has three stages, and they matter differently based on your situation: September 9, 2026 — Final Helm 3 feature release (limited to Kubernetes client library updates only after this date) February 10, 2027 — All security patches stop If your organization runs regulated workloads with requirements around supported software, February 2027 is your hard deadline. But waiting until then means doing this migration under pressure, after 14 months of Helm 4 fixes shipped without you tracking them. The better path: upgrade now, before September, so you're on supported software when new Kubernetes releases land and need updated client libraries. What Actually Broke: The Four Real Changes 1. Post-renderers require plugin registration In Helm 3, you could pass any executable directly to --post-renderer : helm install myapp ./chart --post-renderer ./scripts/mutate.sh Helm 4 drops this. Post-renderers must now be registered as named Helm plugins and referenced by plugin name: helm install myapp ./chart --post-renderer my-post-renderer If your pipeline calls --post-renderer ./path/to/script.sh , it fails on Helm 4. The error message doesn't say "plugin required," so this is easy to miss in a quick smoke test. To wrap an existing script as a plugin, create a plug
