setting up Rancher with certs - example

Docs : https://ranchermanager.docs.rancher.com/getting-started/installation-and-upgrade/resources/add-tls-secrets

install rke2

curl -sfL https://get.rke2.io |  sh -

pros and cons

Pros : clean, simple. Cons : no ingress out of the box. Needs a bit of work to get things going.

talos notes

mkdir ~/Desktop/talos cd ~/Desktop/talos

Anyone Can install RKE2 and Rancher on a Node

RKE2 - Security focused Kubernetes
Rancher - Multi-Cluster Kubernetes Management
Longhorn - Unified storage layer

We will need a few tools for this guide. We will walk through how to install helm and kubectl.

A longer version of this install : Can a 12 y/o install the Rancher Stack?

iPXE with Netboot.xyz

Leverage Docker and Netboot.xyz to host Harvester/Rocky/Liberty installers and kickstart. We have been developing an Harvester Workshop and needed a better way to boot dozens of machines. Netboot.xyz was a simple way to do it. We used https://hub.docker.com/r/linuxserver/netbootxyz to simplify the install.

Then we created a custom menu and loaded the assets. After updating the DHCP settings on the network to point to the machine we are able to boot anything.
