Description

Allow adding additional NICs when Packer is provisioning the virtual machine used to create the image.

Use Case(s)

Some software I am trying to install in an image requires having multiple nics (attached to different subnets) on the machine, and without them, it causes problems. I was wondering if it is possible to have multiple NICs attached to the instance that packer creates so the software installs properly. It might be too niche of a use case, but the current software causes problems when installed with a single nic, so that when you try to boot the image that packer produces, it cannot be reached.

Potential configuration

Perhaps something like

source "googlecompute" "windows-ssh-example" {
  project_id = "MY_PROJECT"
  ...

  network_interface {
    ...
  }

  network_interface {
    ...
  }
}

Potential References

This is supported in terraform when creating a google_compute_instance, but it is not clear to me if this would even be possible in packer.
