What's here

Install - /install

All information on how go from metal until you have SLES, Kubernetes 
(RKE or K3s) and Rancher 

This is where you should start...even if you have SLES install just look.
Make sure you have the proper packages intalled and enabled, turn off or 
open up the firewall and make sure you setup the ssh-keys.

Install SLES

Pick one of the methods below to install SLES

• Installation of SLES15 SP2 on x86_64

• Installation of SLES15 SP2 on Raspberry Pi/aarch64

• Installation and booting of SLES15 SP2 on x86_64 using USB

• Setup cloud-init for KVM installs

• Terraform install of SLES on KVM

Install Kubernetes Tools

• Installation of Kubernetes Tools

Installing Kubernetes

• RKE - Full Blown Kubernetes
  • Simple single-node RKE install on SLES15 SP2 x86_64
• RKE2 (Rancher Government)
  • Install RKE2 (RKE Government) on SLES15 SP2 x86_64
• K3s - Lightweight w/ batteries
  • Install K3s

Install Rancher

We have a couple of options for Rancher.

Rancher normally runs on top of Kubernetes. You pick any of our 
Kubernetes (RKE, RKE2 or K3s) and then install Rancher via helm.  

• Rancher
  • Quick install of Rancher using docker
  • Quick install of Rancher on RKE2 using Rancherd
  • Using helm to install Rancher on k8s

Configuration of cluster after it's up and running

Networking

Configure MetalLB - LoadBalancer that allows you to define a pool(s) of local IP addresses that can be automatically assigned/used by Applications deployed in Kubernetes

Storage

Longhorn - highly available persistent block storage for your Kubernetes workloads

Configure local storage (K3s)

Mounting NFS in a Deployment

Adding Downstream Clusters to Rancher

Now that you have Rancher up and running, it's very easy to create new clusters and import
existing clusters.

Install Downstream RKE Cluster from Rancher

Import existing Downstream Cluster

Deployments

Pi-hole - Network-based ad-blocking software, and a custom DNS server. It blocks ads from being displayed on the devices on your network. It uses DNS sinkholing and blocklists as a way of stopping internet ads, malware, malvertising, etc.

MQTT - Simple, light weight publish/subscribe message bus

NodeRed - Browser based Development Enviroment that make it easy to connect various things together

Install M5Stick - Configuration and tools to setup your M5Stick
