User Story

As a user of MAPI on AWS I want to be able to configure the network interface type so that I can switch from the default interface to the faster EFA network interface for high performance networking

Background

EFA allows faster connectivity between machines for high performance computing workloads. It only works within an AZ and requires some software drivers to work correctly, these limitations are being handled separately.

Ask from us is to provide the means to enable the interface type on the providerSpec and then set the correct setting in run instances.

Steps

• Add a new interfaceType field to the network spec in the providerSpec
• Add validation in webhooks to ensure that the interfaceType is one of the two allowed types
• Manually test that machines join the cluster when they have an EFA network interface as their primary interface

Stakeholders

• Cluster Infra
• Tushar - (Strategic customer case)

Definition of Done

• Users can enable EFA on AWS machines

• Docs

• Documentation of the new field and the prerequisistes for using it should be added to the product docs

• Testing

• Need to enable the interface type and check that the Machines still work as expected.
