Simple RKE2, Longhorn, NeuVector and Rancher Install - Updated for 2024

Throughout my career there has always been a disconnect between the documentation and the practical implementation. The Kubernetes (k8s) ecosystem is no stranger to this problem. This guide is a simple approach to installing Kubernetes and some REALLY useful tools. We will walk through installing all the following.

Hey Clemenko! Thanks to your videos, I am enjoying K8 now :) You got a new subscriber here. May God bless you and may you get many more subscribers soon! One quick question, your account name is very catchy, you are a firefighter too ?

thank you

Thanks for the upgrade and the wonderful guide.

Can you in the future explain how to install apps, manually.

You explain so clearly that everything seems easy.

Hey bro. Great vid. I’ve been binging all your vids and I noticed one thing. You clear your throat every couple of minutes. And it’s loud. Try and take a lozenge or something before filming. I got you on headphones and you blow my ears every time. It’s probably an unconscious thing. Thanks.

Any reason you went with NeuVector? I've never heard of this tool, the only similar one is Wazuh, which by the looks of it seems to be doing the same things as Vector. Thanks for the updated guide!

Hi, until now I had a cluster using talos linux. and I'm looking at the capabilities of rancher and the solution in general, it seems to me a lot of things are automated.
Anyway, I would like to ask, what is this good for please?

1) in the sense of this cluster of three nodes is only educational, or is it a cluster that serves purely for the rancher. and I'm going to use the rancher on this cluster to manage another cluster?
2) what is NeuVector good for, what are its benefits in production?
3) if I have 2-3 physical servers that until now had proxmox and talos linux in them. and I install harvester on them, how good is the eco system, what are the benefits? how well does it work all together?.
4) how does the longhorn choose what disk to use for data? I didn't see any settings there, will it use the first available disk that is not the system disk?
5) how is the code as infrastructure architecture from the connection with rancher, e.g. for example we used to use ArgoCD --> can it be fully integrated into the eco system of rancher, can it be used normally on the rancher cluster? is there any way to force changes made inside rancher to be automatically overwritten on the argocd gitOps repository?

thank you in advance for the answers. and I want to thank you for the video, it was very nice

man, I've been banging my head against my desk all day trying to get this to work. I think there might be something wrong with this setup on ubuntu 24.04.1LTS
After I got everything set up on the main VM, CPU usage spiked and basically froze the entire VM. After a few minutes, it settled down to 60% usage, but any kubectl commands I tried to run timed out. (this was on a vm with 8cpu cores and 10 gigs of ram). I spun up a new VM 4 times trying to troubleshoot and figure out what was going on, but never was successful.
Just spun up a 22.04.5LTS VM and it doesn't seem to be having the same problem... so far.
