Accessing Virtual Machine via NodePort

This page explains how to access a virtual machine using NodePort.

Limitations of Existing Access Methods

  1. Virtual machines support access via VNC or console, but both methods have a limitation: they do not allow multiple terminals to be simultaneously online.

  2. Using a NodePort-formatted Service can help solve this problem.

Create a Service

  1. Using the Container Management Page

    • Select the cluster page where the target virtual machine is located and create a Service.
    • Select the access type as NodePort.
    • Choose the namespace (the namespace where the virtual machine resides).
    • Fill in the label selector as vm.kubevirt.io/name: your-vm-name.
    • Port Configuration: Choose TCP for the protocol, provide a custom port name, and set the service port and container port to 22.

  2. After successful creation, you can access the virtual machine by using ssh username@nodeip -p port.

Create the Service via kubectl

  1. Write the YAML file as follows:

    apiVersion: v1
kind: Service
metadata:
  name: test-ssh
spec:
  ports:
  - name: tcp-ssh
    nodePort: 32090
    protocol: TCP
    port: 22
    targetPort: 22
  selector:
    vm.kubevirt.io/name: test-image-s3
  type: NodePort

  2. Run the following command:

    kubectl apply -f your-svc.yaml

  3. After successful creation, you can access the virtual machine by using ssh username@nodeip -p 32090.
