Kubernetes

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.

We ran the same k6, iperf3 and fio suite on identical Kubernetes clusters on UpCloud, OVH and DigitalOcean. The spec sheets matched; the numbers did not.

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.

Every GitOps rollout stalls on one question: where do the secrets go? A practical guide to SOPS and AGE encryption in Ankra, so credentials live in Git safely and AI-generated config never leaks a key.

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.
