This package adds support for multi-tenant applications.

How it works:

  • Include the Kephas.Tenants package in the application deployment.
  • The application receives the tenant identifier through the tenant command line argument or the KEPHASAPP_Tenant environment variable.
  • The tenant is available in code through IAppArgs.Tenant() extension method or the IContext.Tenant() extension method.
    • Note that IAppArgs are available through dependency injection and IContext instances through the parameter received in context dependent invocations.
  • When setting up the IAmbientServices during application bootstrapping, make sure to invoke the ambientServices.WithTenantSupoport().
    • Do this typically before setting up the application runtime (for example WithStaticAppRuntime, WithDynamicAppRuntime, or WithPluginsAppRuntime), to make sure the runtime accesses the correct locations.

What is the immediate effect:

  • Tenant administrative mode
    • When the application was started without a tenant identifier specified either in command line arguments or in the environment variables. This mode should allow tenant management actions.
    • The folder locations are not changed.
  • Tenant specific mode
    • The tenant identifier is passed to the running application.
    • The folder locations (config, licenses, plugins) are found in the {tenant} subdirectory of the original folder locations.

Check the following packages for more information:


public static IAmbientServices SetupAmbientServices(
    this IAmbientServices ambientServices,
    Func<IAmbientServices, IEncryptionService> encryptionServiceFactory,
    IConfiguration? configuration,
    IAppArgs appArgs)
    return ambientServices
        // Do not forget setting up the tenant support right *after* setting up the application runtime.


Tenants management

A global scope tenantsmanagement permission is provided to require in endpoints or other application actions affecting overall tenants management.

Tenant admin

A global scope tenantadmin permission is provided to require in endpoints or other application actions affecting management of the tenant.

Tenant specific

The TenantSettings are available through the injectable IConfiguration<TenantSettings> service. It provides:

  • DisplayName (string): The tenant's display name.
  • Domains (string[]): an array of domain owned by the tenant. These domains are typically used in the authorization process to identify the tenant a user belongs to.


var config = injector.Resolve<IConfiguration<TenantSettings>>();
var settings = config.GetSettings(context);
settings.DisplayName = "My changed name";
await config.UpdateSettingsAsync(settings, context).PreserveThreadingContext();

Tenant management

The TenantsManagementSettings are available through the injectable IConfiguration<TenantsManagementSettings> service. It provides:

  • GlobalAdmin (GlobalAdminSettings): settings for the global tenants administrator.
  • Tenants (TenantSettings[]): list of settings for the application tenants.


By default, the AmbientServices registers the FolderLocationsManager implementation for the service ILocationsManager. This normalizes the paths and resolves them relative to the application location. Instead, by using IAmbientServices.WithTenantSupport(), this global service is replaced with TenantFolderLocationsManager which appends the tenant identifier prefixed by dot (.) to each of the folders. This has the following effects:

  • The configuration, licenses, plugins, and other locations dependent on the ILocationsManager service will return different locations for different tenants.
  • By prefixing the tenant path element with dot (.), this location is considered hidden by other services and, therefore ignored (checked with location.IsHiddenLocation() extension method).
