- How to evaluate operating systems for your home lab — from Rocky Linux to Talos Linux, and why minimal, immutable operating systems are gaining traction.
- How to implement a three-tier storage strategy combining Longhorn (replicated storage), NFS (bulk storage), and S3 (cloud storage) to handle different workload requirements.
- How to secure your home lab with certificate-based authentication, WireGuard VPN, and proper DNS configuration while protecting your home IP address.

- Experience all aspects of Kubernetes on a smaller scale.
- Make practical decisions on networking, CNI (using Cilium), and distribution choices.
- Address security and persistent storage challenges in an on-premises environment.
- Encounter and solve "nitty gritty edge cases", particularly when using newer ARM hardware.

Daniel emphasizes that this hands-on method provides opportunities to "really think about how you're going to put things out, how to build things up from the ground, look at the tooling available and maybe even contribute" to the Kubernetes ecosystem.

This KubeFM episode shows how to implement efficient deployment previews and solve data seeding bottlenecks.

Nick Nikitas, Senior Platform Engineer at Blueground, shares how his team transformed their static pre-production environments into dynamic previews using ArgoCD Application Sets, Wave and Velero.

He explains their journey from managing informal environment sharing between teams to implementing a scalable preview system that reduced environment creation time from 19 minutes to 25 seconds.

You will learn:

- How to implement GitOps-based preview environments with Argo CD Application Sets and PR generators for automatic environment creation and cleanup.
- How to control cloud costs with TTL-based termination and FIFO queues to manage the number of active preview environments.
- How to optimize data seeding using Velero, AWS EBS snapshots, and Kubernetes PVC management to achieve near-instant environment creation.

Why can't you ping a Kubernetes service?

Learnk8s runs a 4-day Advanced Kubernetes course on Oct 21, and you will get to the bottom of questions like this (spoiler: services only exist in etcd).
You will also learn the nitty-gritty details of Kubernetes networking:

- How to plan and design a cluster network.
- How do the four Kubernetes services extend each other, and what do you gain from each?
- How CoreDNS, Ingress, and kube-proxy consume the Kubernetes currency: endpoints.

This (and much more) is covered on the third day of the course.

You can find the full agenda, a breakdown of the modules and how to sign up here: https://kube.events/t/3aa0148a-d54a-471c-adbc-cc5cabb86d23
