Configuring IP addresses for virtual machines

• Configuring an IP address for a new virtual machine using cloud-init

You can configure either dynamically or statically provisioned IP addresses for virtual machines.

Prerequisites

• The virtual machine can connect to a secondary network

• To configure a dynamic IP for the virtual machine, you must have a DHCP server available on the secondary network.

Configuring an IP address for a new virtual machine using cloud-init

You can use cloud-init to configure an IP address when you create a virtual machine. The IP address can be dynamically or statically provisioned.

Procedure

• Create a virtual machine configuration and include the cloud-init network details in the spec.volumes.cloudInitNoCloud.networkData field of the virtual machine configuration:

  1. To configure a dynamic IP, specify the interface name and the dhcp4 boolean:

     kind: VirtualMachine
     spec:
     ...
       volumes:
       - cloudInitNoCloud:
           networkData: |
             version: 2
             ethernets:
               eth1: (1)
                 dhcp4: true (2)

     1	The interface name.
     2	Uses DHCP to provision an IPv4 address.

  2. To configure a static IP, specify the interface name and the IP address:

     kind: VirtualMachine
     spec:
     ...
       volumes:
       - cloudInitNoCloud:
           networkData: |
             version: 2
             ethernets:
               eth1: (1)
                 addresses:
                 - 10.10.10.14/24 (2)

     1	The interface name.
     2	The static IP address for the virtual machine.
