vip config with predictable interface names

[stelb]

Hi,

I would like to use a VIP for the controlplane nodes, but config examples show:

https://www.talos.dev/v1.5/talos-guides/network/vip/

machine:
  network:
    interfaces:
    - interface: eth0
      dhcp: true
      vip:
        ip: 192.168.0.15

As this did not work, I thought the interfacename might be not correct. And indeed its enxmac
How can I define a vip without manually crafting config files / patches?

Regards

There are two ways:

• disable predictable interface names (net.ifnames=0 on the first boot, it will be persisted after that)
• use Network Device Selectors:

e.g. you could use some "fake" selector if you have a single link (most probably your busPath starts with 0):

machine:
  network:
    interfaces:
    - deviceSelector:
        busPath: "0*"
      dhcp: true
      vip:
        ip: 192.168.0.15
