Outdated - Simple RKE2, Rancher and Longhorn Install

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.

Thank you for providing this guide, it has helped me a lot getting everything to work.
Just a quick note for those using MicroOS as the Operating System: If you've selected the minimum MicroOS Software bundle during the OS installation, you additionally need to have jq and iptables installed on the server node, or you'll run into issues during the installation.
transactional-update pkg in nfs-client open-iscsi iptables jq && reboot

Best Video I have found on this topic, easy . Thanks again Andy!

Been looking at learning Kubernetes and this guide has come in so handy

[CYBONIX]

Thanks to you, I now have a working RKE2 Lab. Thank you very much. I have a lot of learning to do, and this was a great start.

Excellent tutorial. I am now running rke2 + rancher + longhorn, yay!

[MrSpamcho]

Thank you very much for this tutorial, as a beginner in k8s this is flawless!

Any tips on how to proceed further? As to what to deploy/try out and actually become something to a real scenario?

[RobertWilson]

Thanks for the audio guided tutorial. I do have a few questions towards the end of when deploying the flask.

Hi, you dont by anychance have a video yet, or instruction on github for the HA setup with nginx LB ? Would be very much appreciated. Thanks for this already, been a major help!

[stanislavhinov]

Hi Andy, I read your insightful blog post on GitHub about setting up RKE2, Longhorn, and Rancher. I have a couple of questions: Is it possible to skip buying and using DNS for the Rancher UI and instead use kubectl port-forward? Also, can the entire setup be done using just one VM? Looking forward to your advice on these queries. Thanks for the great content!

Andy - what is the recommended method to install the nginx ingress controller on top of rke2? I thought "it" came with rke2 but I don't "see it" after the rke2 install, why is that?

[patrickmamia]

hello @clemenko first of all thanks for that great tuto, i will definitely try to implement this. I read some comment and i can see that many people are waiting for the HA version 😇...
Although I have some questions
1- What are the spec( CPU, RAM, HD) for each of your VM
2- Is it possible to setup HA cluster with 3 VM (including all services needed)?

[AviDarks]

Thanks for the wonderful guide.

Is there an update? It's been almost two years. Maybe there is something new?

Hi Andy, first of all thank you for your great video. I have a question: since we are having the domain/hostname on the first rancher server, what happens if that server goes down? How can we access rancher via URL? -Ben

[MrBigFartz]

I am trying to get two other control planes under one control plane node is that possible? Every time I try starting up the other 2 control plane rke2 services it runs into an error.

Hi Andy, greetings, thanks for the tutorial, it helped me a lot to set up my kubernetes environment, the question I have is the following, I could activate the domain with a private ssl certificate and the web works perfectly, but when I download the kubeconfig file to manage it in the Lens Desktop, it tells me the following error, tls: failed to verify certificate: x509: certificate signed by unknown authority, I hope your answer, and in advance thank you very much

[JohnnysaidWhat]

is it possible to run the cluster locally on a mac or pc? The way microk8s uses a vm for example?

[kiki-vuif]

Thank you so much for this tutorial. I'm having trouble setting it up in HA... any video coming soon ?😅

[IamDmitriev]

Very, very useful info. But I can nor understand the reason to use rke2-agent service on the second and the third nodes. In my opinion - it should be rke2-server on all three nodes. In this case this construction can be used for HA rancher deployment when we deploy three replicas of Rancher.

[siyandamakhalima]

Thank you very much for the video. How is the last tab terminal (reminal 3) a sever but you run a script for node agent ?
