You can use kargo-cli to start new instances on cloud providers here's an example
kargo [aws|gce] --nodes 2 --etcd 3 --cluster-name test-smana
With kargo-cli
kargo deploy [--aws|--gce] -u admin
Or ansible-playbook command
ansible-playbook -u smana -e ansible_ssh_user=admin -e cloud_provider=[aws|gce] -b --become-user=root -i inventory/single.cfg cluster.yml
