## Using Kubernetes Service auto-discovery
When running `mc-router` as a Kubernetes Pod and you pass the `--in-kube-cluster` command-line argument, then
it will automatically watch for any services annotated with
- `mc-router.itzg.me/externalServerName` : The value of the annotation will be registered as the external hostname Minecraft clients would used to connect to the
routed service. The service's clusterIP and target port are used as the routed backend. You can use more hostnames by splitting them with comma.
- `mc-router.itzg.me/defaultServer` : The service's clusterIP and target port are used as the default if
no other `externalServiceName` annotations applies.
