The prerequisites for creating a Kubernetes cluster are:

The Kubernetes-as-a-service component. It can be deployed along with the compute cluster or later (refer to "Creating the compute cluster" or "Provisioning Kubernetes clusters" in the Administrator Guide).
A virtual network that will interconnect Kubernetes nodes. It needs to have a gateway and a DNS server specified.
An SSH key that will be installed on both the master and worker nodes.
Enough resources for all of the Kubernetes nodes, taking their flavors into account.

Example:

# vinfra service compute k8saas create k8s1 --kubernetes-version v1.20.7 \
--master-node-count 1 --node-count 3 --volume-storage-policy default \
--master-flavor medium --volume-size 10 --external-network public \
--network private1 --flavor small --key-name key1 --use-floating-ip true \
--vinfra-username user1 --vinfra-password password --vinfra-domain domain1 \
--vinfra-project project1
