multipass_k3s_multi_node.md

Single Node Install

Setup the master node as instructed here:

Multi Node Setup

Provision a Worker Node:

$ multipass launch bionic --name k3s-node-1 --cloud-init=./cloud-init.yaml

Set the Master and Agent IP's to your environment:

$ export K3S_MASTER=$(multipass info k3s-master | grep 'IPv4' | awk '{print $2}')
$ export K3S_AGENT=$(multipass info k3s-node-1 | grep 'IPv4' | awk '{print $2}')

Install the agent and join the cluster:

$ k3sup join --server-ip ${K3S_MASTER} --ip ${K3S_AGENT} --user multipass --ssh-key ~/.ssh/multipass

View the nodes:

$ kubectl get node -o wide
