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.
