Performance of ApiServer Extension for Network Function Configuration in Kubernetes Environment

Traditional telecommunication network functions often require configuring thousands of parameters, resulting in large configuration files. The built-in capabilities of Kubernetes struggle to manage the vast number of parameters in a single configuration file, leading to workarounds that are not native to Kubernetes. This paper proposes an automated, Kubernetes-native configuration deployment procedure based on GitOps principles and the Kubernetes API aggregation layer. This approach can solve the problems originating from the existence of large configuration files. Furthermore, we show numerical results about the deployment times to illustrate the engineering cost of the new approach.
