Contour Gateway Provisioner: How to Setup Envoy to use HostNetwork

[hbobenicio]

What question do you have?:

How do I setup Envoy to run using Host Network when using the Contour Gateway Provisioner for Gateway API?

Anything else you would like to add:

As I'm using the Gateway Provisioner, I don't have full control of the DaemonSetSpec/PodSpec of the managed envoys. I can edit it later after it's provisioned by contour but won't contour override it eventually because he doesn't know about these outside customizations?

I suppose contour could/should also manage envoy's container hostPort to match the gateway's listeners port, right?

Environment:

• Contour version: 1.30
• Kubernetes version: (use kubectl version): v1.30.4
• Kubernetes installer & version: Kubespray v2.26.0
• Cloud provider or hardware configuration: On-Premises
• OS (e.g. from /etc/os-release): Not relevant

after some investigations I fear this is not possible atm, unfortunately.
