Starting With K3S (Lightweight Kubernetes) and MicroOS

Course details

Lightweight Kubernetes (k3s) allows us to deploy a very low-footprint infrastructure to everything from big data centers to a Raspberry Pi that sits in remote locations. SUSE has provided us with a very simplified Kubernetes distribution that can be used in home labs for free or in data centers with vendor support. MicroOS will allow us to use an immutable operating system in which we can deploy a static system that is the same across the entire cluster. This also allows us to easily apply updates on a running system and roll back the system to a previous state at the filesystem level. Longhorn allows us to easily provision storage for our Kubernetes workloads. Helm will allow us to easily deploy applications into our environment with the simplicity of a package manager.

In this course, we will be setting up a high-availability Kubernetes environment sitting on top of an immutable MicroOS environment. We will start with some concepts and information about K3S. We will then move over to set up a three-node HA Kubernetes (k3s) environment. Upgrading your environment is important, and we will be updating both K3S and MicroOS.

You will see over an hour's worth of technical content and should be able to take this knowledge to set up a home lab or even production environment. So, join me in getting started in this exciting product developer by Rancher Labs and now owned by SUSE.

I have been using Kubernetes for ~4 years now in both home lab and enterprise environments. I have been working in IT for over 12 years now in Linux, Windows, cybersecurity, and many other roles.
