Kestra 2.0 is here, and in this tutorial I’ll show you how to automate DigitalOcean with it. We’ll walk through the brand new DigitalOcean plugin, build our Kestra flow, and add inputs so the flow can be reused with different values. If you’ve been looking for an open-source way to automate your cloud infrastructure, this one’s for you!
Learn how to create a Linux Golden Image on Linode and use it to deploy secure, preconfigured VPS instances in minutes.
In this hands-on Linux tutorial, you’ll learn what a Golden Image is, why system administrators use them, and the best practices to follow when building one. We’ll prepare a reusable Linode image by installing updates, preinstalling essential packages, configuring Fail2ban, and converting the finished VPS into a deployment-ready template.
By the end of the lab, you’ll be able to launch new Linux servers from your Golden Image – saving time, improving consistency, and eliminating repetitive server configuration.
Every time you create a new user account on a Linux system, the files that land in their home directory have to come from somewhere – and that somewhere is /etc/skel. In this video I walk through what the skel directory actually is, how it gets used during account creation, and how you can leverage it so every new user on your servers and workstations starts out with exactly the configuration you want.

Do you actually know how fast your network is? Not what your switch spec sheet says — what it’s really doing between two hosts. iPerf3 is the tool sysadmins and homelab enthusiasts reach for when they need real answers, and in this video I’ll show you how to use it from the ground up.
We cover everything from installation to practical usage, including how to test WiFi vs wired, push a 10 gigabit ethernet connection, bind to a specific interface, and dial in your test parameters for accurate results.
If you’ve ever rebooted a Linux server and had it fail to come back up, there’s a good chance the culprit is sitting right in your /etc/fstab file. Device names like /dev/sda1 can shift after a reboot, a drive swap, or even a kernel update — and when that happens, your mounts break and your server may not boot at all. In this video, I break down why UUIDs matter for Linux storage, and I show you a real production server that ran into exactly this problem.
Manually spinning up VMs in Proxmox gets old fast. In this video, I’m using Kestra (an open-source workflow automation platform) to automatically clone a VM template and start it, all without touching the Proxmox UI! You’ll see the process of buiding the workflow, setting up the Proxmox API – and more! In this step-by-step video, you’ll be able to build this for yourself.
Thanks to Kestra for supporting this tutorial! You can self-host it and use it to automate entire workflows , so check it out!
