Once you have kubectl set up, the full power of Kubernetes is at your fingertips! There’s a lot to learn before you can build exascale applications to serve bajillions of requests per second, though. In this post, we’ll get familiar with pods. Create a pod The term pod is k8s-ese for container, basically. Technically, a pod can have multiple containers in it, but usually it just has one. Pods are pretty much the only reason K8s exists; everything else about K8s revolves around getting traffic to and from pods....

This is a series on how to get your feet wet with Kubernetes (K8s). We won’t talk about the nitty-gritty details, since the K8s docs serve that purpose already. The purpose is to give an overview and some familiarity with what K8s is and how it works. In this post, we’ll set up your machine with the basics so that you can start working in a K8s cluster. Assumptions for the series:...

Kubernetes is all the rage in the web developer world these days, and it’s gaining traction in the AI/ML community as well. Kubernetes is basically an engine that runs containers in the right place at the right time, accessible by the right entities…And containers are basically just individual, isolated programs with a whole lot of marketing hype. Simple enough, right? This post describes how to get started as an administrator (not a developer) of a cluster from scratch....

Encrypting a drive in Linux used to be an extremely cryptic (I’m not sorry) process. Now, while it still is not entirely straightforward, there are tools to make it less painful. Even better, most desktop environments will handle mounting and unmounting encrypted volumes automatically with a simple password prompt once you get the drive set up. For this tutorial, I assume you want to encrypt an external USB drive and that you don’t mind wiping it first....

Sometimes you just need an NFS server. This guide will show how to start a simple, albeit insecure (public read/write), NFSv4 server in a Docker container on a Raspberry Pi. I assume the Pi is all set up and ready to go and that you’ll use an external drive for storage. I also assume you’re at least familiar with parted or fdisk. Prepare storage drive (If you already have your external drive formatted and mounted, skip this section....

These are brief instructions for setting up a headless Raspberry Pi in a controlled manner. I assume you’ve done this sort of thing before and are just looking for a quick reference. Prep First, get the Raspbian Lite image. Use Etcher to put the image on an SD card. You can just use the Raspbian .zip file (no need to unzip). Networking Mount the rootfs volume on the SD card. You can do this from the file explorer GUI if you like....
