Authorization Provider Strategy for Application Registration
Supported Authentication Plugins
OAuth2 plugins for use with the Application Registration plugin:
When Kong Gateway is the system of record, the Application Registration plugin works in conjunction with the OAuth2 or the Key Authentication plugin.Important: The OAuth2 plugin does not support hybrid mode. If your organization uses hybrid mode, you must use an external identity provider and configure the OpenID Connect plugin.
When an external OAuth2 is the system of record, the Application Registration plugin works in conjunction with the OpenID Connect plugin.
The third-party authorization strategy (
external-oauth2) applies to all
applications across all Workspaces (Dev Portals) in a Kong Gateway cluster.
Authorization provider strategy configuration for Application Registration
portal_app_auth configuration option must be set in
kong.conf to enable
the Dev Portal Application Registration plugin with your chosen
authorization strategy. The default setting (
kong-oauth2) accommodates the
OAuth2 or Key Authentication plugins.
kong-oauth2: Default. Kong Gateway is the system of record. The Application Registration plugin is used in conjunction with the OAuth2 or Key Authentication plugin. The
kong-oauth2option can only be used with classic (traditional) deployments. Because the OAuth2 plugin requires a database for every gateway instance, the
kong-oauth2option cannot be used with hybrid mode deployments.
external-oauth2: An external IdP is the system of record. The Portal Application Registration plugin is used in conjunction with the OIDC plugin. The
external-oauth2option can be used with any deployment type. The
external-oauth2option must be used with hybrid mode deployments because hybrid mode does not support
Set external portal authentication
If you are using an external IdP, follow these steps.
kong.conf.defaultand set the
portal_app_authoption to your chosen strategy. The example configuration below switches from the default (
kong-oauth2) to an external IdP (
portal_app_auth = external-oauth2 # Dev Portal application registration # auth provider and strategy. Must be set to configure # authentication in conjunction with the application_registration plugin. # Currently accepts kong-oauth2 or external-oauth2.
Restart your Kong Gateway instance.
Enable the Application Registration plugin on a Service.
Enable a supported authentication plugin on the same Service as the Application Registration plugin, as appropriate for your authorization strategy.
- If using the
kong-oauth2authorization strategy with the OAuth2 plugin, configure the OAuth2 plugin on the same Service as the Application Registration plugin. You can use either the Kong Manager GUI or cURL commands as documented on the Plugin Hub. The OAuth2 plugin cannot be used in hybrid mode.
- If using the
kong-oauth2authorization strategy with key authentication, configure the Key Auth plugin on the same Service as the Application Registration plugin. You can use the Kong Manager GUI or cURL commands as documented on the Plugin Hub.
If you plan to use external OAuth2, review the recommended workflows.
If using the third-party authorization strategy (
external-oauth2), configure the OIDC plugin on the same Service as the Application Registration plugin. You can use the Kong Manager GUI or cURL commands as documented on the Plugin Hub. When your deployment is hybrid mode, the OIDC plugin must be configured to handle authentication for the Portal Application Registration plugin.
Configure the identity provider for your application, configure your application in Kong Gateway, and associate them with each other. See the Okta or the Azure setup examples.
