Kubernetes

Back up a Kubernetes 1.37 cluster by hand with etcd snapshots, then delete the control plane and restore it. Includes the encryption key trap, all tested.

Read every Kubernetes certificate, watch one expire, and renew them all by hand. Most components reload a renewed certificate with no restart at all. Tested.

Build GitOps from scratch on Kubernetes 1.37. A Git repository, a reconcile loop with kubectl server-side apply and pruning, drift repair, rollback, all tested.

Build a Kubernetes 1.37 control plane that survives losing a server. Three control planes, etcd with TLS, a load balancer, and failure drills, all tested.

Build Kubernetes pod networking by hand with network namespaces, veth pairs, a bridge, routes and NAT, then call a CNI plugin yourself and trace a Service. Tested.

An internal developer platform gives every team a self-service path to production and the organisation one place to govern it all. Learn what an IDP includes and how one platform serves a two-person startup and an enterprise of many teams.

Learn how to ship to Kubernetes without tickets using GitOps, standard templates, scoped access, and deployment workflows that preserve production control.

Kubernetes the Hard Way, updated for Kubernetes 1.37 and Debian 13. Every command tested end to end, on local machines and on Hetzner Cloud.

Take an app built with Cursor, Claude Code, Lovable, Bolt or Replit to production in 2026. What production adds, the hosting routes compared, how to pick.

Twelve AI tools for Kubernetes compared, from open source troubleshooters to AI operations platforms and MCP servers, and how each one handles write access.

Flux with a web UI, Akuity, Harness, Octopus, Rancher Fleet, Devtron and Ankra compared, plus when plain Argo CD is still the right call.

Hosted European PaaS or push-to-deploy in your own EU cloud account? Nine Heroku alternatives compared by headquarters, hosting location and fit.

Rancher, OpenShift, Spectro Cloud, Kubermatic, Portainer, Mirantis, Platform9, Azure Arc, Omni and Ankra compared, with who each fits.

Hetzner has no managed Kubernetes. Eight ways to run it in 2026, from kube-hetzner and Talos to Syself, Cloudfleet and Ankra, and what each leaves to you.

Northflank, Qovery, Porter, Ankra, Coolify, Dokploy, Kamal, Render and Railway compared, with where each runs your apps and who it fits in 2026.

Eight Rancher alternatives for 2026 compared side by side, from OpenShift and Spectro Cloud to Portainer and Omni, with when each one fits.

Ankra's own platform now runs in Helsinki. The timeline, the bill, the benchmark numbers, and the places UpCloud let us down, from the team that did the move.

Moving a Next.js app on Vercel with a Supabase backend onto a Kubernetes cluster you own. What maps across, the database move, and the hard parts.

Every Ankra Playground size costs less than the Hetzner server of the same shape, with Kubernetes, TLS and storage included. The math, and the fine print.

We turned a production OpenSearch stack into a reusable Ankra stack profile. The parameterisation exercise turned into an audit, and it found credentials that went nowhere, a security config that was never applied, and a retention policy pointed at every index in the cluster.

What 10 heavy Claude developers cost, why one 8xB200 server cannot run Kimi K3, and the UpCloud cluster that could.

A compose stack on a VM, a Kubernetes cluster on Ankra, and the databases in between. ankra migrate up plans, converts, deploys, dumps and restores, then does it once more for the cutover. Here is what one command has to promise, and how the CLI keeps that promise.

Public AI chat quietly leaks IP and breaks NDAs. Deploy a private chat and API on a GPU you own: your data stays home and every token has a known price.

We gave an AI agent one paragraph: build an animated deep sea facts page, wire it to our private GPU, ship it. It came back with a live URL. Here is how.

From an empty UpCloud account to a Kubernetes cluster running a team of AI agents, each with its own personality, chat channel and keys, all building through GitOps.

We ran the same k6, iperf3 and fio suite on EKS, GKE and Hetzner and lined the results up against UpCloud, OVH and DigitalOcean. The cheapest node in the test won more than it had any right to.

Two identical cloud VMs measured 2.8x apart on CPU; one failed etcd's fsync bar. A 15-minute in-cluster benchmark suite catches this before production does.

UpCloud vs DigitalOcean vs OVH on identical Kubernetes clusters. UpCloud led on storage and network, OVH on latency, DigitalOcean had the slowest tails.

ingress-nginx is retired and its successor was cancelled before it shipped. A migration path to Gateway API that does not require a big-bang weekend.

The 'never run a database on Kubernetes' rule predates CSI and operators. What production Postgres takes in 2026, and when managed still wins.

Three releases a year, 14 months of patches, and a 6x cluster fee when you lapse. How to turn Kubernetes upgrades from a dreaded project into a routine.

Three weeks ago we called CVE scanners a layer-seven answer for teams who skipped the layer-one work. Then we shipped one. Here is why that is not a contradiction, and what a vulnerability finding has to become before it is worth anything.

Kubermatic KKP is an open source factory for manufacturing Kubernetes clusters at density, and you are the one who runs the factory. Ankra is the platform your team does not have to operate. An honest comparison from a fellow European vendor.

A new name, a new engine, and the biggest release we have ever shipped: the Go rewrite, an AI that owns the incident loop, passkey security, European multi-cloud, and Ankra on your phone.

Half of all clusters are running an ingress controller that stopped receiving security patches in March. Meanwhile, teams debate service meshes. The five findings that show up in every real cluster security review, each with the incident that proves it and the fix.

Manage GitOps secrets by encrypting each value with SOPS and AGE before it reaches Git. Only ciphertext is committed and decrypted at deploy time.

On June 15, Hetzner raised cloud prices, with some instance families more than doubling. A worked-numbers look at what a production Kubernetes cluster costs now, and why the real lesson is portability, not provider loyalty.

Spectro Cloud's Palette is a serious enterprise platform for provisioning Kubernetes estates from the OS up. Ankra is an AI-native platform for running everything that happens on Kubernetes from the app down. The honest comparison, including when Palette is the right call.

New Ankra clusters no longer run ArgoCD. Here is the engineering story of the native deployment engine: why we built it, how the reconcile loop works, what the migration does to your live resources (nothing), and what we have not finished yet.

Prometheus is the right first monitoring stack for almost everyone, and the wrong last one for a growing minority. An honest comparison of the two, the cardinality wall that forces the question, and how to run either (or both) on Ankra.

Every logging decision is secretly one question: how much of your log data do you index? A working comparison of Elasticsearch, OpenSearch, Grafana Loki, and cloud services like GCP Logs Explorer, with real pricing math and a decision framework.

'Don't use Kubernetes until you have a platform team' was good advice in 2019. The premises changed. What a two-to-six person company should set up in week one, what to deliberately skip, and what it actually costs: about zero.

A practical guide to wiring an infrastructure agent into your CI: review comments on pull requests, deploy verification on merge, and Slack reports that contain an actual root cause instead of a red X.

Cursor is good at application code but loses context the moment a change crosses into Kubernetes, Helm, and CD pipelines. Adding the Ankra CLI as an infrastructure subagent gives it cluster-aware grounding so developers and platform teams can work on the same artifacts.

AI agents have wiped real production databases this year. Replit's went down during a code freeze, Cursor's took nine seconds via Terraform. Here's how Ankra's draft-first, GitOps-backed AI gives teams a senior DevOps agent without that failure mode.

Komodor's Klaudia is a good AI SRE. Ankra is the next step: an AI that operates the full lifecycle of your apps and infrastructure, runs on any Kubernetes you bring, and keeps Git as the source of truth. Here's the honest comparison.

A real walkthrough of using Ankra Stacks to clone production-like infrastructure for local development, on-demand staging, QA review, and client demos. From OrbStack on a laptop to GitHub Actions to production.

Edge Kubernetes is exploding, but our operational tooling has not kept up. Here is how Ankra delivers a true single pane of glass combining AI-powered troubleshooting, native GitOps, and stack cloning to turn weeks of cluster setup into minutes.

Stop drowning in alerts. Learn how Ankra's AI-powered incident management delivers root cause analysis and actionable fixes directly to Slack, reducing debugging time from hours to minutes.

Traditional CI is fine. Delivery is where teams still bleed time. Learn how Ankra transforms delivery from a scripting problem to a graph problem, reducing pipeline build time from weeks to hours.
