Using Firecracker VM as k3s worker node

Community Support

Hello,
I have successfully deployed a HA k3s cluster on 3 nodes (RPi 4).
Now I need additional worker nodes, and my plan is to deploy Firecracker VMs for this.

Can you please advise if this is possible?
And if yes, how should I proceed?

Hi Thomas,

You should be able to use Firecracker microVMs for this. You can find an example of using Firecracker microVMs as K3s nodes here: CNCF Webinar - K3s at the Edge for Multiplayer Gaming - OpenNebula – Open Source Cloud & Edge Computing Platform.
