Start Service#

New in version 2.0.

ESS provides a service that acts as the starting point for the ESS user interface.

Start Service Endpoint#

ESS Start Service hosts an application that runs at:

https://start.{ESS Domain}

ESS Start Application#

The ESS’ start application allows a user to sign up or login with the Identity Provider. You can replace the default start application with a custom start application.

Create a WebID#

Start applications can call ESS’ WebID service to create a WebID and manage the WebID profile document. The application can derive the WebID service’s endpoints by concatenating:

  • the WebID Service’s base URL and

  • the username portion of the webid claim (from the ID token).

Create a Pod for WebID#

Start applications can call ESS’ Pod provision service to provision the Pod for the user.

Add Pod Location to WebID Profile#

Once provisioned, start applications can call the ESS’ WebID service to update the WebID profile document with the Pod location.

Start Application Configuration#

To use with the various ESS services, the following configuration options must be set to the start application’s Solid-OIDC Client ID:

For example, the default ESS start application has https://start.{ESS DOMAIN}/app/id as its Client ID, and the provided overlays use this value in the configuration.

If using a custom start application, update the configuration to the the custom start application’s Client ID.

See Use a Custom Start Application.


As part of the installation process, Inrupt provides base Kustomize overlays and associated files that require deployment-specific configuration inputs.

The following configuration options are available for the service and may be set as part of updating the inputs for your deployment. The Inrupt-provided base Kustomize overlays may be using updated configuration values that differ from the default values.


The base URL of the Pod Provisioning Service.


The value requires a trailing slash /; e.g., https://provision.{ESS_DOMAIN}/.

The ESS’ Start application uses this value to determine the ESS’ Pod provisioning endpoint.


The base URL of the WebID Service.


The value requires a trailing slash /; e.g., https://id.{ESS DOMAIN}/.

The ESS’ Start application uses this value to determine the base URL of the ESS’ WebID service endpoints.


Default: INFO

Logging level.


The URL of the Solid OIDC Broker Service.


Default: https://start.{ESS DOMAIN}/app/id

The Solid-OIDC Client ID (i.e., the URL that dereferences to a Client ID document) of the start app for signing in/up with the Identity Provider.
