## Installing the Chart

The Chart can be installed quickly and easily to a Kubernetes cluster. Since an _Ingress_ is added as part of the default install of the Chart, the `ingress.host` Value must be specified.

Install the Chart using the following command from the root of this directory:

```shell
helm upgrade -i -n kubernetes-mcp-server --create-namespace kubernetes-mcp-server oci://ghcr.io/containers/charts/kubernetes-mcp-server --set ingress.host=<hostname>
```

### Optimized OpenShift Deployment

Functionality has been added to the Chart to simplify the deployment to OpenShift Cluster.
