    Get k3s with OpenFaaS using k3sup and multipass

multipass from Canoncial is like Docker Desktop, but for Ubuntu and works on MacOS, Linux and Windows.
Use-case:
We can get a Kubernetes cluster with k3s in a very short period of time. We can use this for workshops and building labs, and for R&D, including testing.


Get multipass.run


Create cloud-init.yaml


#cloud-config
ssh_authorized_keys:
  - ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC8Q/aUYUr3P1XKVucnO9mlWxOjJm+K01lHJR90MkHC9zbfTqlp8P7C3J26zKAuzHXOeF+VFxETRr6YedQKW9zp5oP7sN+F2gr/pO7GV3VmOqHMV7uKfyUQfq7H1aVzLfCcI7FwN2Zekv3yB7kj35pbsMa1Za58aF6oHRctZU6UWgXXbRxP+B04DoVU7jTstQ4GMoOCaqYhgPHyjEAS3DW0kkPW6HzsvJHkxvVcVlZ/wNJa1Ie/yGpzOzWIN0Ol0t2QT/RSWOhfzO1A2P0XbPuZ04NmriBonO9zR7T1fMNmmtTuK7WazKjQT3inmYRAqU6pe8wfX8WIWNV7OowUjUsv alex@alexr.local

runcmd:
- curl -SLsf https://get.k3sup.dev | sh
- mkdir -p /home/ubuntu/.kube/
- k3sup install --local --local-path /home/ubuntu/.kube/config
- curl -sLfS https://cli.openfaas.com | sh
- HOME=/home/ubuntu k3sup app install openfaas | tee /home/ubuntu/post-install.txt
- echo "export KUBECONFIG=/home/ubuntu/.kube/config" | tee -a /home/ubuntu/.bashrc
- chown ubuntu:ubuntu -R /home/ubuntu/


Edit the ssh_authorized_keys and replace with your own $HOME/.ssh/id_rsa.pub value


multipass launch ubuntu --name k3s-1 --cloud-init=./cloud-init.yaml


Run multipass info k3s-1 and get the IP and set export IP="" with the value


Next run:


k3sup install --user ubuntu --ip $IP --skip-install
This step will download the KUBECONFIG file from the VM, that you can use to access OpenFaaS and your k3s cluster!

Grab the OpenFaaS post-install instructions: ssh ubuntu@$IP cat post-install.sh

You're now good to go.
