This repository contains source code for k8s custom operator for OpenAirInterface RAN functions (CU-CP, CU-UP, DU) which can be deployed in Nephio.
The operator is currently common for all the RAN functions (CU-CP, CU-UP, DU).
The operator listens to the NFDeployment CRD. The operator decides which Network function the CR is intended for based on the Provider field in the NFDeplymentSpec. The operator retrieves the custom configuration required for the Network function from the NFConfig CR.
Here is an example for the NfDeployment CR for CU-CP. The CR also contains the reference to custom configuration NFConfig CR as part of the parametersRefs.
The KPT package used for deploying the RAN operator is located in the nephio/catalog repository.
The KPT packages for deploying the RAN Network functions (CU-CP, CU-UP, DU) are located in the catalog repository.
Note:
- The CR is only the initial CR and it will get specialized by Nephio and more fields will added before the CR is applied in the cluster.
- Dynamic updates of the NFdeployment CR is currently not supported by the operator.
