nf-deploy-fn

Overview

The nf-deploy-fn is a KRM function leveraging the cond sdk using the workload.nephio.org/v1alpha1.NFDeployment as for KRM resource.

The upf deployment function has 3 watch resources:

• req.nephio.org/v1alpha1.Interface
  • For every interface resource status, it will use status.ipAllocationStatus and status.vlanAllocationStatus fields to populate NFDeployment spec.interfaces values.
• req.nephio.org/v1alpha1.DataNetwork
  • For every datanetwork resource status, it will use status.pools.ipAllocation fields to populate NFDeployment spec.networkInstances values.
• req.nephio.org/v1alpha1.Capacity
  • This resource is the source of truth for the capacity details in NFDeployment spec.
• req.nephio.org/v1alpha1.Dependency
  • For every dependency resource in the package, injected configs will be appended to spec.parametersRefs. Dependency is discovery and injection should be done separately.

The function generates a final resource with the same name as the Kptfile. It does not panic or error out if status fields are missing for any resource. It generates the NFDeployment using the available data.

usage
