# 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.
