Description

Add support for builds using static IP address assignment.

Use Case(s)

Provides examples for environments that are unable to use DHCP (default).

Potential Configuration

To be determined.

There's not a native method in the Packer Builder for VMware vSphere to use static IP address assignment.

Options to enable this may include:

Examples

Ubuntu 18.04

Update the ks.cfg preseed file.

# Networking
d-i netcfg/disable_autoconfig boolean true

# IPv4 Setup
d-i netcfg/get_ipaddress string <static_ipv4_address>
d-i netcfg/get_netmask string <static_ipv4_netmask>
d-i netcfg/get_gateway string <static_ipv4_gateways>
d-i netcfg/get_nameservers string <static_ipv4_dnsservers>
d-i netcfg/confirm_static boolean true

Ubuntu 20.04 and later

Update the user-data used by cloud-init.

  network:
    network:
      version: 2
      ethernets:
        ens33:
         addresses: <static_ipv4_address_cidr>
         gateway4: <static_ipv4_gateway>
         nameservers:
           addresses: [<static_ipv4_dnsservers>]

Windows Server

Update the autounattend.xml with Ipv4Settings.
