[@dundydunker]

This is by far the best kubernetes guides I have ever seen

[@VinceBaker]

Fantastic fully covered walk-through. Excellent work as usual. Thanks Marcel.

[@AlexisHernandez-fv5vg]

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

[@Lets_talk_about_it_]

Just got into devops, my job wants me to spin up quick. These have got to be the best videos I've stumbled upon period. Thank you Marcel!

[@alexandreramos7569]

Awesome video! Thx Mr. for your kindness to show us this amazing architecture.

[@WelcomeWithinMyDream]

Thanks for your video and happy to see you're safe.

[@niketsingh87]

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!

[@ddpxl]

What a great introduction to rancher! Well done!

[@90DaysOfDevOps]

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.

[@krvns]

Truly awesome content with no bs!

[@johnreyna5080]

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.

[@hakanutkuozdemir1407]

These are really detailed tutorials. Thank you for this!

[@dmitriykrayniy5846]

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.

[@rlobarros]

Thank you for a excellent guide. Clear concise and well put together. Once again EXCELLENT!!!!

[@gizmoamp]

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.

[@chrisumali9841]

Thanks for the demo and info, very helpful and concise. Have a great day

[@jmmtechnology4539]

Always find your videos informative, thanks!

[@iamabrantes]

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

[@van-khoanguyen8430]

Excellent work ! Thanks Marcel.

[@ZimTachyon]

Wow your presentation alone is worth the subscription.

[@andreigiubleanu]

Great video Marcel ! Keep up to the good work!

[@charlettedavis2153]

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.

[@wantstuff]

Wow! Seriously, this the best video I have found. Well done

[@thelensoftruth]

Great video! The only thing missing from this tutorial is making sure your Windows OS enables the Hyper-V role through settings

[@stefanschmidbauer6075]

Great video. The videos are so good, I watch them during my lunch break :)

[@FabianoChagas]

Awesome as always. Thanks for sharing.

[@ketanranade4564]

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.

[@conwayniall]

Love it...insightful as always :D thanks!

[@yashsachdeva2829]

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.

[@mohammadtalep9913]

Great video. Thanks for the effort

[@Joy-vo4ne]

Thank you sir for your hard work. Your video is very helpful.

[@nabsan0320]

Thank you your video. its very easy to understand. your my teacher.

[@dorinxtg]

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.

[@realbootybabe]

Before I saw this video I thought setting up Kubernetes in a private cloud needs hours of hours to get Kubernetes running. Thanks a lot!! :-)

[@kodikodi9948]

this is great. really great. thank you!

[@ashermanangan]

Thanks for this video!

[@aPaCHuNEe]

awesome stuff , thank you

[@esaieledouxnjongssikouam9326]

Merci beaucoup , ... Très bon tuto Très belle vidéo

[@AhmedGamal-eo3ns]

wow, this is the best explain for Rancher on youtube

[@victorcasad]

Great video! Love it!

[@ganeshmhaske33]

Really great video, Can you please create video on production grade rancher setup with fail-over and HA management.

[@lightafterdark4453]

Always Excellent

[@vivekraj6794]

I am big fan of your videos sir, i try to follow it.

[@MateuszDrankowski5]

Great video!

[@pratahsinnetamby]

Great video - many thanks. I was hoping you would use RKE2 to create the cluster. Any reason you didn't (a novice here!)?

[@skvtech228]

Excellent video on rancher. Can you please make video on High availability setup for Rancher server. Thanks Marcel.

[@jeremycoe7259]

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.

[@praxorizor]

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, ...?

[@JaY-rr2hg]

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.

[@joeharyar9873]

Hi..great video...if running openstack vm (kvm) should I run 'custom' ? Thank you

[@michaelgraff6978]

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.

[@maciejrozz3327]

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!

[@dm5665]

But is it possible to manage vanilla k8s running on Baremetal from Rancher?

[@buacomgiadinh1]

wait for your next videos :)

[@huimi8569]

I like your style

[@heatheryoung7498]

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!!

[@rchalicham]

this is really cool , can you tell something cool walk thru for KVM,OVS and rancher?

[@cd-stephen]

appreciate you

[@dqfold5557]

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 ? Do you use them ? In the book by Ibryam + Huß there are many patterns explained. But on KZbin and blogs people usually only talk about the Sidecar, Adapter and Ambassador patterns. I am very curious about your opinion on this. Thank you !

[@javisartdesign]

Thanks. It really helps! It does not work with cri-o or containerd?

[@MarcelDempers]

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 💪🏽

[@Fayaz-Rehman]

Super hit - Thank you for sharing. I wonder, we did not disable/delete swap on the nodes. Is it done by rancher automatically?

[@MarcelDempers]

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.

[@Fayaz-Rehman]

@@MarcelDempers Thank you - I appreciate.

[@vivahernando1]

Great video. I have a question for everyone ….. why does it seem like Ubuntu is the preferred distro for baremetal

[@rabigurung7188]

Am I able to add Raspberry PI (ARM64) in the Rancher RKE cluster? I get stuck in the node provisioning stage. Thanks.

[@MarcelDempers]

I've heard folks doing so, but have not tried it myself. Would have to consult the docs

[@ugurserhattoy]

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.

[@ugurserhattoy]

SOLVED: !!! It's fixed by redeploying metrics-server. !!!

[@marcziel5424]

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.

[@coboogaart7833]

Great video only a lot of manual infra setup why don't you use vagrant with hyper-v provider much easier :)

[@MarcelDempers]

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

[@technoparkbd4631]

Hello. i have two vm one is rancher and another one is kubernetes cluster how to connect kubernetes cluster from rancher. Please help me.

Please share the link with the text, I can't seem to find it in the source.

oh yeahhhhh 💪

[@ashik9001]

Great content for this video 👍,can you make one concourse CI/CD pipeline video on top of kubernetes?

[@DingoAteMeBaby]

have you tried K3s?

[@MarcelDempers]

Not yet, but very keen!

[@allisondealmeida]

Didn't kubernetes stop supporting docker? Using the Kubernetes cluster with Rancher can I use it in production?

[@manuelthallinger7297]

I think they stopped supporting Docker Images, not the installation of rancher on Docker itself.

[@pix3lize]

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 :)😅

[@nt3900]

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]

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

[@nt3900]

@@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

[@elchinefa9524]

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.

[@irfanshaikh9440]

Great video on Rancher I have ever seen. Is it possible for you to make video on Openshift using OKD?

[@elchinefa9524]

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.

[@nbctcp3450]

he use windows to run Hyper-V server and under it he create a linux server for rancher

[@kellyburton]

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.

[@nbctcp3450]

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

[@user-rd2fs5lu9g]

... Not for production
