I started both Windows 10\Virtualboxvms\microk8s & Windows 10\Virtual box vms\k8s. Small 14 inch laptop with 16 gbs of ram With 300GB USB connected storage. All kubes ran on calico. LB running on HAProxy. The virtual machines I ran custom unattended installs of ubuntu. That was a pain but custom ISO's for each VM. I am still a little old fashion and save my work on Notepad++. You and Tech nana explain things very well. I have worked big infrastructure and small ones as well. Keep up the good work.
Great video to know more about Rancher! I have deployed a k8 cluster bare metal with 5 physical worker/control-plane nodes and 2 virtual nodes for control plane, is distributed into three failure zones and it uses metallb as load balancer service
I agree with everyone that these are the best videos. I plan to share them with my new counter partner who is just starting with RKE. Again, I agree with everyone these are the best videos. I plan to share this with some of my counter partner who's new to the team into RKE. I have subscribed and plan to join for the small monthly fee. It's worth it! Thank you.
I had difficulties because i did all on a ubuntu/bionic64 on virtualbox, the hardest problem was use the kubeconfig because when i started the vms useing vagrant the current user is vagrant, but when i setted the config on the folder kube all the things were solved, thanks from Brazil :D
amazing tutorial. Nothing skipped. Same tut can be used to setup this on AWS EC2 also. Simple, easy to follow detailed steps. Thanks a lot Marcel. God Bless ya!
My K8s clusters are deployed and configured manually on VMs, K8s cluster upgrades im doing also manually and im using metallb as LB. I will try this one - thank you for walk-through Marcel.
Great video, thank you. We use kubeadm and ansible to spin up kubernetes for on-premises, because we like to create infrastructure by automated scripts.
Hi Marcel, Would be good if you did a deep dive on Rancher features similar to what you did for Portainer. It would help decide which is the best Kubernetes management tool out there.
Great video! If I may suggest something: Don't use the ISO, use a cloud image and after adding your config, convert it to a template. That way you could spin 3-4 machines within minutes without lot of work.
Always great content. I want to include rancher in my 90DaysOfDevOps and my Kubernetes section. You tackle a large part of it but Rancher could be the winner when it comes to getting that UI to manage Kubernetes.
Thank you for the video know-how. Can I just use Rancher to setup a kubernetes with etcd/master/work nodes/roles , and then remove Rancher ? I simply want to use Rancher for the first cluster setup, and then manage the cluster(s) administration on my own.
The one thing I seriously dislike about Rancher is how intrusive it is. The last time I tried it, I installed it on my Raspberry Pi cluster, and while it worked, and seemed kinda handy... I decided to remove it. That's when my problems started. It adds hooks into every pod, deployment, statefulset, etc. If you then remove Rancher, and at the time perhaps I did not remove the cluster from rancher's control properly... but it left my cluster in a very, very confused state. I could not delete pods. I could not create new ones. I had to hunt down and remove all sorts of delete hooks, admission controller configurations that no longer exist, etc. I just use ArgoCD now to deploy, and Lens 5 to manage the cluster in a UI way when needed. I'm still very much a command line person, so I tend to have a pile of manifests, which Argo can easily consume.
Hi Marcel, your videos have been very helpful. Thanks a lot and Keep on the great work! Just a request, if you could do a video on configuring multi-master cluster using kubeadm on AWS ec2 instances that would be great.
Are you able to do a video where you use Rancher without Docker? A lot of companies are doing away with Docker because they’re now charging for licenses. I’ve performed several of your videos using nerdctl (with Lima) and Rancher. I think such a video would be helpful :). Thank you!!
Nice Video, love it :-). Can you make a video about some k8s operators like k8ssandra, eck, strimzi ... or some cool tools like lakefs, minIO, dremio, trino, ...?
Great tutorial. I am following along, but when I try to register the linux nodes the Rancher state is stuck at "Reconciling" and it doesn't go any further. I even removed the cluster from Rancher and created a new one by adding a freshly created linux vm with Docker. Any suggestion to resolve the problem are appreciated.
theres lots of steps to fix here, also devops way is to install 1 vm and clone it xx times. Im sure your going to develop devops mindset soon will all work your doing! Gread vid!
Nice video. You talked about adding a Metal LB. Could you please make a video where you set that up for an on-prem HA K8s cluster where we 3 Control-planes, 3 workers and 3 Etcd?
@@MarcelDempers Thank you for your answer. Can we in the context of the video set up a functioning HA cluster without a Load Balancer? If not, any guidance on setting up a HA k8s cluster (At least 3 control planes, 3 workers and 3 etcd? ) with rancher?? Thanks
It doesn't work any more! it's always loop [controlPlane] Failed to upgrade Control Plane: [[host linux-1 not ready]]. Any help will be appreciated :)😅
Good video generally but you're talking about immutable vms and how advantageous it is but all you do is mutating vms in place. You should prepare an image for worker/master nodes and use that instead fiddling with the same commands through ssh.
The tutorial focus is rancher, which leave you to use any automation tools of your choice. Manual setup is extremely important in tutorials to understand how things work
1. 29:00 could I use dns name instead of ip address 2. u hv 3 kube servers and u use static ip address. better use ip address or use static dhcp server (dhcp with static ip based on mac address) coz I ever heard changing ip in k8 more difficult than windows. I am not sure about that 3. u r using ubuntu in ur k8 servers can I use Alpine instead coz lighter coz alpine isn't supported in rancher, I'll stick with Ubuntu for rancher vm only
Maybe it will help someone. I faced issue with running rancher. It kept rebooting, thtat is why could not open localhost. After some research figure out Ubuntu 20.0.4 is right one for me.
kubectl command for the cluster is responsing so slow. Do you have an idea why? I tried even on the master node itself. The docker container for rancher is working on it too.
I did not disable SWAP, it may be done during the k8s install by Kubernetes itself or by Rancher. I have a suspicion its done by the K8s process itself, but you'd need to test it out.
Why create an additional layer of virtualization with hyperv? I'd understand if you'd run something else on the same physical machine, perhaps another cluster or operating system, but if the only purpose of that machine is to be a kuber cluster why bother?
Hello Marcel, Thanks again for this new video. I have a question about Kubernetes patterns. You talk a lot about devops, but you never post videos about patterns. I'm curious to know what you think ?

Wow! Seriously, this the best video I have found. Well done
Great video, thank you. We use kubeadm and ansible to spin up kubernetes for on-premises, because we like to create infrastructure by automated scripts.
wow, this is the best explain for Rancher on youtube
Great video! The only thing missing from this tutorial is making sure your Windows OS enables the Hyper-V role through settings
Thanks for the demo and info, very helpful and concise. Have a great day
What a great introduction to rancher! Well done!

Can you please create video on production grade rancher setup with fail-over and HA management.
Thank you your video. its very easy to understand. your my teacher.
Great video. The videos are so good, I watch them during my lunch break :)

Excellent video on rancher. Can you please make video on High availability setup for Rancher server. Thanks Marcel.
Thank you sir for your hard work. Your video is very helpful.

Just a request, if you could do a video on configuring multi-master cluster using kubeadm on AWS ec2 instances that would be great.
Great video - many thanks.
I was hoping you would use RKE2 to create the cluster. Any reason you didn't (a novice here!)?
Great video Marcel ! Keep up to the good work!

Marcel do you have any video about installing RKE2 from scratch if yes please share..highly needed
Nice Video, love it :-). Can you make a video about some k8s operators like k8ssandra, eck, strimzi ... or some cool tools like lakefs, minIO, dremio, trino, ...?
Great video! Love it!
awesome stuff , thank you
Love it...insightful as always :D thanks!
I am big fan of your videos sir, i try to follow it.
Please make an complete video on Ranchar CD part as well❤
Thanks for this video!
subbed! This guide is really awesome! But wondering if I can deploy an NGINX as a loadbalancer and how to apply SSL certificate to rancher itself.
Always Excellent

Metal LB is something I am still learning. Might be showcasing it in the future for sure 💪🏽

Am I able to add Raspberry PI (ARM64) in the Rancher RKE cluster? I get stuck in the node provisioning stage.
Thanks.
I've heard folks doing so, but have not tried it myself. Would have to consult the docs
It doesn't work any more! it's always loop [controlPlane] Failed to upgrade Control Plane: [[host linux-1 not ready]]. Any help will be appreciated :)😅
this is really cool , can you tell something cool walk thru for KVM,OVS and rancher?
But is it possible to manage vanilla k8s running on Baremetal from Rancher?
Great video. I have a question for everyone ….. why does it seem like Ubuntu is the preferred distro for baremetal
Hi..great video...if running openstack vm (kvm) should I run 'custom' ? Thank you
Good video generally but you're talking about immutable vms and how advantageous it is but all you do is mutating vms in place. You should prepare an image for worker/master nodes and use that instead fiddling with the same commands through ssh.
Great video only a lot of manual infra setup why don't you use vagrant with hyper-v provider much easier :)
The tutorial focus is rancher, which leave you to use any automation tools of your choice.
Manual setup is extremely important in tutorials to understand how things work
Thanks. It really helps! It does not work with cri-o or containerd?
I can't see how it shouldn't work, however would have to consult the rancher docs to be certain. Or atleast give it a go and see 💪🏽

Hi. Here 33:06 i don't understant . You said before for rancher we need linux host but you use windows. Really, I'm confused.
he use windows to run Hyper-V server and under it he create a linux server for rancher
nice tutorial. Are you aware of how to deploy rke cluster via rancher using code in Terraform or something like that ?
Hello. i have two vm one is rancher and another one is kubernetes cluster how to connect kubernetes cluster from rancher. Please help me.
kubectl command for the cluster is responsing so slow. Do you have an idea why?
I tried even on the master node itself. The docker container for rancher is working on it too.
SOLVED: !!! It's fixed by redeploying metrics-server. !!!
Please share the link with the text, I can't seem to find it in the source.

I like your style
wait for your next videos :)
Didn't kubernetes stop supporting docker? Using the Kubernetes cluster with Rancher can I use it in production?
I think they stopped supporting Docker Images, not the installation of rancher on Docker itself.
Super hit - Thank you for sharing. I wonder, we did not disable/delete swap on the nodes. Is it done by rancher automatically?
I did not disable SWAP, it may be done during the k8s install by Kubernetes itself or by Rancher. I have a suspicion its done by the K8s process itself, but you'd need to test it out.
@@MarcelDempers Thank you - I appreciate.
Can we do this with proxmox?
Why create an additional layer of virtualization with hyperv? I'd understand if you'd run something else on the same physical machine, perhaps another cluster or operating system, but if the only purpose of that machine is to be a kuber cluster why bother?

Great video on Rancher I have ever seen. Is it possible for you to make video on Openshift using OKD?
Not sure why you used docker to run Rancher. For my workshop I spun up three VMs running linux and then installed rancher on the VM, no docker needed.
appreciate you
You should probably systemctl enable it instead of start. Otherwise on reboot it won't be started automatically and you'll lose ssh access
oh yeahhhhh 💪
Great content for this video 👍,can you make one concourse CI/CD pipeline video on top of kubernetes?
