+h2. Exported configuration
+
+The Controller exposes a subset of the cluster's configuration and makes it available to clients in JSON format. This public config includes valuable information like several service's URLs, timeout settings, etc. and it is available at @/arvados/v1/config@, for example @https://{{ site.arvados_api_host }}/arvados/v1/config@. The new Workbench is one example of a client using this information, as it's a client-side application and doesn't have access to the cluster's config file.
