Creating a VM that runs debian#

In this guide, you’ll learn how to deploy a simple VM that runs debian.

Installation#

Create debian-vm.yml:

---
apiVersion: kubevirt.io/v1
kind: VirtualMachine
metadata:
  name: debian-vm
  namespace: vms
spec:
  runStrategy: Always
  dataVolumeTemplates:
    - metadata:
        name: debian-vm-rootdisk
      spec:
        storage:
          storageClassName: longhorn
          accessModes:
            - ReadWriteOnce
          resources:
            requests:
              storage: 8Gi
        source:
          registry:
            url: "docker://quay.io/containerdisks/debian:13"
  template:
    metadata:
      labels:
        kubevirt.io/size: small
        kubevirt.io/domain: debian-vm
    spec:
      domain:
        devices:
          disks:
            - name: rootdisk
              disk:
                bus: virtio
            - name: cloudinitdisk
              disk:
                bus: virtio
          interfaces:
            - name: default
              masquerade: {}
        resources:
          requests:
            memory: 1Gi
            cpu: "1"
      networks:
        - name: default
          pod: {}
      volumes:
        - name: rootdisk
          dataVolume:
            name: debian-vm-rootdisk
        - name: cloudinitdisk
          cloudInitNoCloud:
            userData: |
              #cloud-config
              password: debian
              chpasswd: { expire: False }
              ssh_pwauth: False
              ssh_authorized_keys:
                - <your ssh.pub key>
              runcmd:
                - systemctl enable --now ssh
            networkData: |
              version: 2
              ethernets:
                enp1s0:
                  dhcp4: true
                  addresses: [ fd10:0:2::2/120 ]
                  routes:
                    - to: ::/0
                      via: fd10:0:2::1

Expose ssh port using MetalLB svc:

apiVersion: v1
kind: Service
metadata:
  name: debian-vm-service
  namespace: vms
spec:
  selector:
    kubevirt.io/domain: debian-vm
  ports:
  - name: ssh
    port: 22
    targetPort: 22
  type: LoadBalancer

You should be able to ssh into this vm, once created, using the LoadBalancer IP.
```
kubectl -n vms get svc debian-vm-service
```
