# Features | ||
|
||
This page will cover configuration of various Oracle Cloud Infrastructure Container Engine for Kubernetes (OKE) | ||
features in CAPOCI. | ||
|
||
## Node Pool Cycling | ||
OKE [Node Pool Cycling][node-pool-cycling] can be used during Kubernetes version upgrades to cycle | ||
the nodes such that all the nodes of a Node Pool is running on the newer Kubernetes version. The following | ||
`OCIManagedMachinePool` spec can be used to specify Node Pool cycling option. | ||
```yaml | ||
apiVersion: infrastructure.cluster.x-k8s.io/v1beta2 | ||
kind: OCIManagedMachinePool | ||
spec: | ||
nodePoolCyclingDetails: | ||
isNodeCyclingEnabled: true | ||
``` | ||
|
||
## Addons | ||
The following `OCIManagedControlPlane` spec should be used to specify [Addons][addons] which has to be | ||
installed in the OKE cluster. | ||
|
||
```yaml | ||
kind: OCIManagedControlPlane | ||
apiVersion: infrastructure.cluster.x-k8s.io/v1beta2 | ||
spec: | ||
clusterType: "ENHANCED_CLUSTER" | ||
addons: | ||
- name: CertManager | ||
``` | ||
More details about the configuration parameters are available in [CAPOCI API Reference docs][api-reference]. | ||
