You can customize the settings of control plane components in a professional managed Kubernetes cluster to meet production needs. You can customize the settings of managed components such as Kube API Server and Kube Controller Manager (KCM). This topic describes how to customize the settings of control plane components in professional managed Kubernetes clusters.
- After you customize the settings of a component, the component is automatically restarted. We recommend that you customize the settings during off-peak hours.
- After you customize the settings, the changes overwrite the default settings of the professional managed Kubernetes cluster.
- To ensure the stability of the control plane component, you are allowed to customize only some of the settings.
- Make sure that the values of the customized parameters are valid and complete. Otherwise, the component may fail to be restarted. For more information about the parameters, see kube-apiserver and kube-controller-manager.
