Create SSH key pair to be used for Kubernetes master and node machine

ssh-keygen -f ~/.ssh/scw-k8s-cks -t rsa -b 4096 -C "toth.janci@gmail.com"

If you want to create a new instance via command line scw binary

scw instance server create type=DEV1-S zone=fr-par-1 image=ubuntu_focal root-volume=l:20G name=scw-k8s-cks ip=new project-id=431d432b-1849-445f-a66b-7d1ccdf5d34a

SSH to the machine

ssh -i ~/.ssh/scw-k8s-cks  root@51.158.106.182

Provision Kubernetes master node

bash <(curl -s https://raw.githubusercontent.com/killer-sh/cks-course-environment/master/cluster-setup/latest/install_master.sh)
