Home Server - Part 6: When the Router Runs the Fallback DNS

Part 5 ended on a confession: AdGuard on the home server is now critical infrastructure. If that container goes sideways — a bad update, a docker compose down at the wrong moment, the server hanging on a kernel upgrade — every device on the trusted VLANs loses DNS. Internet stops. The household notices in roughly four seconds.

The traditional answer is “buy a Raspberry Pi.” I didn’t want to, and the router had a better idea anyway.

Learning k8s, KCNA preparation (Part 4)

In this installment of this KCNA series, we’ll dive into the fundamentals of Kubernetes and explore how it helps manage containers at scale. Running a few containers can be straightforward, but when dealing with hundreds or thousands of containers, efficient management requires more than basic tools—it needs a sophisticated orchestration platform. This is where Kubernetes excels.

Learning k8s, KCNA preparation (Part 3)

In this third part of the series, we’ll dive into the fundamentals of Containers, crucial to understanding the benefits that container orchestration via Kubernetes bring. You’ll gain insights into how containerization revolutionizes application deployment and management, while Kubernetes provides the orchestration needed for scalability and resilience. Lets explore the power of containers in modern application development.
