MacOS compatible VM runtime that uses the system hypervisor (though you can switch to VirtualBox).
It's easy to spin up a linux node with whatever image, resource limits, etc.
multipass launch --name my-ubuntu-node --cpus 2 --disk 100G --mem 4G focalLightweight Kubernetes for edge/iot applications that seems to me to be a cool potential self-hosting solution.
Run the setup.sh script if you need to install multipass using brew. This will also install gum for some CLI sparkle. From there...
The deploy_gum.sh script provides a decent promt-based shell script (thanks to gum) to guide you through the set-up (you don't have to do this often). You can fly through with defaults and you'll get 1 control plane and 1 worker each with 1 cpu, 2G mem, and 10G disk. Or you can enter in the details as you go and control the number of workers and the resources for each node individually.
Top-level options in the Gum Workflow looks like this:
./deploy_gum.sh:
--install_k3s
--install_helm
--uninstall_all
--exitYou have to install_k3s before you can install_helm into the cluster.
uninstall_all wipes out the multipass VMs and therefore any k3s, helm or whatever else was deployed.
The deploy.sh script can help deploy k3s as well if you want a one-command way to do it, and you can hard-code the resource for the workers and control-plane in the script as needed.
- ./deploy.sh install N will create N workers in a k3s cluster
