Hi:wave:,

This repo contains bunch of scripts to get you easily up and running with Kubernetes + Rancher 2. It uses K3S, a lightweight variant of K8S developed by the rancher people. You can obviously install standard K8S - and still control it by Rancher 2. In such case ignore first 3 steps.

Installation

You should have:

• 1 VPS for running rancher 2, the k8s master node
• X VPS for running worker nodes

😲 for the cheapest setup, they can be the same node!

Instructions

1. On each node run install-pkg.sh to get necessary packages
2. On master node, run install-k3s.sh
3. Start k3s with /usr/local/bin/k3s server or /usr/local/bin/k3s server --docker if yo usee containerd related errors.
4. On master node, set hostname in /etc/hostname. Make sure hostname prints the full hostname with domain name.
5. On master node, get LetsEncrypt certificate by calling ./certbot.sh [email protected]
6. Run rancher ./rancher2.sh. It will start rancher in a container and display logs. You can ctrl-C any time to stop output, it will not kill rancher.
7. Kill rancher with ./kill-rancher2.sh
8. Open the host in your browser, you should see rancher

If all worked fine

1. Copy k3s.service to /etc/systemd/system and enable it systemctl enable k3s.service
2. Your container runtime should also be enabled by default (containerd or docker)
3. You might want to enable swap - see create-swap.service (A one time service to create a swap file) and swap.service (enable swap on each boot)
