Description

Feature request

The OCI Terraform provider supports network_launch_type on oci_containerengine_node_pool:

• VFIO
• PARAVIRTUALIZED
• E1000

This is needed to create OKE worker node pools with VFIO VNIC attachment.

Current behavior

The OKE module documents SR-IOV extensions for Kubernetes networking, but the worker/node pool configuration does not appear to expose the OCI provider's network_launch_type argument.

Because of that, users cannot configure the underlying node pool VNIC attachment launch type through the module.

Requested behavior

Please expose network_launch_type in worker pool configuration and pass it through to the underlying oci_containerengine_node_pool resource.

Internally this could map to:

network_launch_type = try(each.value.network_launch_type, null)

Potential Terraform Configuration

worker_pools = {
  pool1 = {
    # existing settings
    network_launch_type = "VFIO"
  }
}
