Nice😊. I had to try it. Workes on the first try. Good job again jim 👍

Great video! Tested today and fully working. Good job Jim!!

there is no enough likes for your video, the amount of work that you put into this is incredible, thanks, i'm waiting for my new homelab server to try all of this.

Thanks for the demo and info, have a great day

Well delivered and easy to comprehend, thanks again for awesome content!

Interesting. I'll be giving this a shot, I hadn't heard of RKE2 before. Thanks for the video!

Thank you and happy new year! 🥂🍾 I can confirm that both rke2 and longhorn works even on debian12 cloud generic (with a little bit of tuning of the script - like the ssh - and the installation of open-iscsi on the workers)

Thank you! Will give this a try

Great one Jim. Thanks for this great video. I was just about to hack your k3s script to use RKE2. There is already lots of content about this version. There's a big move going on from K3s to RKE2.

Hey Jim, great video and script again. I'm on my own homelab journey too and your videos have helped me so much, as I'm also a Linux newb as well (know enough to be dangerous). I'm late to this video because I had some issues with some equipment. Thought I'd just jump in the deep end with this as had already followed your k3s setup but figured I'd keep upto date. Script worked perfectly after I figured out an issue with something two feet in front of keyboard as I copied and pasted your script like yourself into WinSCP, but could not get it to run with a error message "/bin/sh^M: bad interpreter" till I work-out about unix format. Hope you are still using rke2 as am following along, keep up the good work.

I know that must have taken quiet a lot of time getting that script to work as expected.. There are always things that we overlook hehe... Appreciate all you do and it is very helpful indeed!

Great video!!!😉Jim, are you planning on doing a tutorial of how to deploy RKE2 cluster using an Ansible playbook?

Hi Jim, Great video and very high success rates from the looks of the feedback, although I do have 1 concern and that is combing RKE2 & Longhorn all on the single network, I built a K3S\Longhorn cluster and experience huge performance issue due to Longhorn replication and automatic snapshotting processes....how difficult would be to segregate the storage network from the RKE2 pod and ingress network? Cheers

I love this series, and it's very good for learning about kubernetes in all shapes and sizes. Excellent to see someone go through it and have an opportunity to play along. I'm wondering though, why not create a script-download-run-embed in an image like with cloud-init. Having your own github repo host the version of the script that you need to run on each node, and then having an image for every master/worker that you can apply and copy. On startup it would get the github script, and run it on first boot to set itself up within the cluster. This makes everything much more parallel, since the scalability of this script ends if you want to do - say - 10 workers and masters. Since you have to wait for each one before going on to the next one.

I saw your script and the only thing I could think was; ANSIBLE :)

Thanks for the video, I'm really looking forward to deploying it. Do you have any video/guidance on how to setup the SSH certificates to make sure your script works as intended?

You are the boss!

Thanks once for the great videos ❤ , a little request please zoom in more when viewing the scripts the texts i mean as i am watching you from mobile 😅 , thanks

Hello Jim, Great video. Do you know if it's possible to change the cluster IP from the default 10.43.x.x to something else, in case that range is already in use on the network?

This is cool! Would be nice to automate this with something like ansible as well

Wow I can wait to build a lab to try all of this!

RKE2 Hype! RKE2 Hype!

How many of Jim's videos do I need to search before I find where he generates the cert files? I have plain old kvm/qemu not Proxmox. I can ssh into all of my nodes using ssh keys (passwordless) from the kvm hypervisor host. What sort of certs files are expected?

The script contains also metallb (not mentioned in the video). What's the reason to include both metallb and vip?

Cause myself extra problems by using two sets of ssh keys. One from main pc to admin vm and from admin vm to rke cluster nodes. Had to do a round robin public key authorization on the admin node for the script to work. As I said my fault. Script worked flawlessly once I figured that out. Only took me 3 months to figure out. 😅

thanks jim for the informative videos, is the script working with redhat OS

Would you be able to create a video showing how to set up RKE2 on a Raspberry Pi cluster?

What tools did you use to scan the vulnerabilities?

Just a quick thought, any reason why this does not deploy as LXC on proxmox other than "security" ?

Hi, I've been trying out your cilium version, however it does not work. The lb-range does not exist in your cilium config and the vip is unable to get created as well. Any fixes regarding this?

Should the local cluster not be left for rancher management abs a new cluster with workers etc be deployed separately so you aren't giving local access to all your services?

Hey Jim, thanks so much for the video series, super helpful! I'm having a weird issue with the script however. It's asking for the password for the admin box during running. Appears to be happening during step 3, at line 147-149. When I start typing the admin password, it displays text typed in clear text. Am I missing something obvious here? Testing using all ubuntu 2204 server nodes on top of an esxi cluster.

Hi Jim, maybe its time to Terraform and Ansible to automate creating VMs :) or maybe cloudinit templates by scripts?

Great video, work first time, i struggle a bit in first go, realised RAM needed Atleast 5 GB and disk space 30 GB to finish the cluster setup comfortably. My setup is behind pfsense , and i use HAProxy to offload cert and redirect to port to access all app in network. However there is some extra setup need to be done with Metallb and BGP mode. I have the pfsense side ready to accept the request from Metallb using FSS plugin. But I am not sure how/what to modify the Metallb to advertise the loadbalancer ip to pfsense. Any help ?

Hello Jim, is your script to install RKE2 with Cilium works? Because I would like to do some tests but I am not sure if it is there but it is still "work in progress" or not (since there are some comments about kube-vip installation but without really install it)

Btw how many cpu and ram you finally gave to rke2? Looks like they are more resource intensive

just ran the script after 25mins it end with ::1]:8080: connect: connection refused, The connection to the server localhost:8080 was refused - did you specify the right host or port?

certificates? you mean ssh key. specifically the public key.

Why use script? Why not ansible? I know bash scripts are bread and butter for us. But ansible is clean and idempotent.

Can I suggest changing the following line as indicated (to pick up the actual certName)? Current: ssh-copy-id $user@node Changed: ssh-copy-id -i $certName $user@node
