# Cluster add-ons PCD Kubernetes clusters support 2 types of add-ons * Core Add-ons * The add-ons are critical for the functionality of your Kubernetes cluster, which include CNI, CoreDNS etc. * Other Add-ons * These are add-ons supported and managed by PCD to extend the capabilities of Kubernetes and provides services such as Load-Balancing services etc. * This release of PCD Kubernetes Clusters supports only [MetalLB](https://metallb.io/). * Note: PCD only deploys MetalLB controllers on the Kubernetes Cluster and you still have to [configure MetalLB](https://metallb.io/usage/example/) after the cluster creation is complete. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
