From Zero to kubectl in 5 Minutes — Managed Kubernetes on Your Own Metal

Thu, 04 Jun 2026 00:00:00 +0000

Every platform team has faced this: a new project needs a Kubernetes cluster. With cloud providers, that means a new billing account, region selection, networking decisions, and a baseline cost of $70–300/month before a single pod runs. Self-hosting with kubeadm? Days of setup, certificates, etcd management, and upgrade anxiety. Rancher helps, but you’re still managing the lifecycle yourself.

What if creating a production-grade Kubernetes cluster was as simple as filling out a form?

Platform-Managed Backups in Cozystack

Sun, 31 May 2026 00:00:00 +0000

Backups are everyone’s responsibility and, too often, nobody’s job. On a multi-tenant platform the problem is sharper: tenants want to protect their own databases and VMs, but they shouldn’t be handed S3 credentials or asked to wire up storage. Cozystack closes that gap with platform-managed backups — a clear API where tenants declare what to protect and the platform takes care of where and how.

Managed PostgreSQL with Synchronous Replication — Without the Ops Headache

Fri, 17 Apr 2026 00:00:00 +0000

Setting up PostgreSQL with synchronous replication the hard way means Patroni configs, etcd clusters, pgBouncer, monitoring exporters, backup scripts, failover testing — easily a week of work before you even store a single row. And then you still need to maintain it. AWS RDS solves this but locks you into a cloud bill that grows faster than your data.

What if you could get managed PostgreSQL on your own hardware in two minutes?

A Simple Way to Install Talos Linux on Any Machine, with Any Provider

Talos Linux is a specialized operating system designed for running Kubernetes. In my opinion, it does that task better than others. First and foremost it handles full lifecycle management for Kubernetes control-plane components.

On the other hand, Talos Linux focuses on security, minimizing the user’s ability to influence the system. A distinctive feature of this OS is the near-complete absence of executables, including the absence of a shell and the inability to log in via SSH. All configuration of Talos Linux is done through a Kubernetes-like API.

Installing a Kubernetes Cluster Managed by Cozystack: A Detailed Guide by Gohost and Ænix

This article was written by Vladislav Karabasov from Kazakhstani hosting company gohost, therefore the narrative will be conducted in the first person.

At the time of my transition to gohost.kz, the company had already been operating in the Kazakhstan market for 15 years, providing clients with a standard set of services: VPS/VDC, IaaS, virtual hosting, etc. However, clients developed new needs, so I was tasked with developing the direction of Kubernetes as a Service.

Configuring routing for MetalLB in L2 mode

Not so far ago, I was faced with a quite unusual task of configuring routing for MetalLB. All would be nothing, since MetalLB usually does not require any additional configuration from user side, but in our case there is a fairly large cluster with a quite simple network configuration.

In this article I will show you how to configure source-based and policy-based routing for the external network on your cluster.
