 That's it! As soon as the above cluster has booted, it'll announce itself and communicate its URL to the `MultiClusterWebServer`.

In the next release this configuration is changing from `.andAutoDiscovery("https://multi-cluster.acme.com/multi", "my-api-key", "Order fulfillment service")` to `andApiKey("my-api-key").andAutoDiscovery("https://multi-cluster.acme.com/multi", "Order fulfillment service")`.

 ### Authentication
 
 The Multi-Cluster Dashboard supports the same [user authentication schemes]({{< ref "guides/authentication" >}}) as a regular JobRunr Pro Dashboard. The only way to authenticate server-to-server communication is to configure shared API keys. Once configured, servers pass the key along with each request. A valid API key provides full access to all the endpoints.
