Background

Containerized Network Functions (CNFs) are the evolution of network functions in the Cloud and very often are deployed on the same hardware that is already used for the Virtualized network Functions (VNFs).

Starting with  OpenShift 4.8, we allow the user to add additional networks to the workers and create Neutron ports with configurable "vnicTypes". 

- port:
    vnicTpe: direct 

For usecases based on SR-IOV the vnicType is "direct", other options are available. 

The default is "normal" [1]

In 4.9, we will improve the User Experience for our customers deploying those types of configurations.

Goals

• Automate some tasks that can be automated and that are today documented to be run manually by our customers, which can be error prone and not user-friendly.
• Update the documentation once things are getting automated.
• Test that the automation works fine in QE environments.

Acceptance Criteria

• Developers can reproduce an environment with NFV configuration and test the features while developing it
• QE has a testing strategy.
• The newly automated features are documented
