Examples Kubevirt

Create VM (kubevirt.io/v1alpha3, Debian 9):

cat <<EOF | kubectl apply -f -

Create VM old (kubevirt.io/v1alpha2, Debian 9):

cat <<EOF | kubectl apply -f -
apiVersion: kubevirt.io/v1alpha2
kind: VirtualMachine
metadata:
  name: debian
spec:

              volumeName: containervolume
              disk:
                bus: virtio
            - name: cloudinitdisk

                  root:toor
                expire: False
EOF

Conect to vm:

kubectl get vms
virtctl start debian

virtctl console debian

Create VM with Debian 10

Currently Debian 10 has problems to start with cloud-init, you can use the following example to use it and solve the problem temporarily.

cat <<EOF | kubectl apply -f -
apiVersion: kubevirt.io/v1alpha3
kind: VirtualMachine
metadata:
  name: debian
spec:
  running: false
  template:
    metadata:
      labels: 
        kubevirt.io/size: small
        kubevirt.io/domain: debian
    spec:
      domain:
        cpu:
          cores: 2
        devices:
          disks:
            - name: containervolume
              disk:
                bus: virtio
            - name: cloudinitvolume
              disk:
                bus: virtio
          interfaces:
          - name: default
            bridge: {}
        resources:
          requests:
            memory: 1024M
      networks:
      - name: default
        pod: {}
      volumes:
        - name: containervolume
          containerDisk:
            image: tedezed/debian-container-disk:10.0
        - name: cloudinitvolume
          cloudInitNoCloud:
            userData: |-
              #cloud-config
              bootcmd:
                - echo cloud-init=disabled > /etc/cloud/cloud-init.disabled
                - [ /bin/bash, -c, 'echo -e "demopass\ndemopass" | passwd root' ]
                - reboot
EOF

Example in docker
