User Story:

As a developer working on the agent-based installer, I want to be able to:

• Remove the validation in validateHostInterfaces() within installer/pkg/asset/agent/agentconfig/agenthosts.go that requires at least one network interface to be defined for each node.

so that I can achieve

• Allow host roles to be defined even when MAC addresses or network interfaces are not provided.
• Enable configurations to rely on hostnames instead of MAC addresses for assigning roles.
• Improve flexibility in defining host roles in scenarios where MAC addresses are unavailable.

Acceptance Criteria:

Description of criteria:

• Sample agent-config.yaml

• apiVersion: v1beta2
  rendezvousIP: your-node0-ip
  hosts:
  - hostname: change-to-hostname-1
    role: master
    rootDeviceHints:
      deviceName: /dev/sda
  - hostname: change-to-hostname-2
    role: master
    rootDeviceHints:
      deviceName: /dev/sda
