## Configure the Konnectivity service
The following steps require an egress configuration, for example:
{{< codenew file="admin/konnectivity/egress-selector-configuration.yaml" >}}
You need to configure the API Server to use the Konnectivity service
and direct the network traffic to the cluster nodes:
1. Create an egress configuration file such as `admin/konnectivity/egress-selector-configuration.yaml`.
1. Set the `--egress-selector-config-file` flag of the API Server to the path of
your API Server egress configuration file.
