title: Map Host Cluster Service to vCluster Service
sidebar_label: From Host to vCluster
---

For example, to map a service `my-host-service` in the namespace `my-host-namespace` to the virtual cluster service `my-virtual-service` in the virtual cluster namespace `my-virtual-namespace`, you can use the following config in your `values.yaml`:

```yaml
mapServices:
  fromHost:
  - from: my-host-namespace/my-host-service
    to: my-virtual-namespace/my-virtual-service
```

With this configuration, vCluster will manage a service called `my-virtual-service` inside the virtual cluster that points to the host service `my-host-service` in namespace `my-host-namespace`. So pods inside the vCluster will be able to access the host service via e.g. `curl http://my-virtual-service.my-virtual-namespace`.

To apply this change to an existing vcluster instance, simply run the following command:

```
vcluster create <CLUSTER_NAME> -f values.yaml --upgrade
```
