Authentication in Red Hat Developer Hub
Configuring authentication to external services in Red Hat Developer Hub
Abstract
1. Understanding authentication and user provisioning
This module provides an overview of how authentication and user provisioning function within Red Hat Developer Hub. Learn about the process from creating user and group entities in the software catalog to user sign-in, and how authentication and catalog plugins enable each step. Understanding this process is essential for successfully configuring your Developer Hub instance, securing access through authorization, and enabling features that rely on synchronized user and group data.
To fully enable catalog features, provision user and group data from the Identity Provider to the Developer Hub software catalog. Catalog provider plugins handle this task asynchronously. These plugins query the Identity Provider (IdP) for relevant user and group information, and create or update corresponding entities in the Developer Hub catalog. Scheduled provisioning ensures that the catalog accurately reflects the users and groups in your organization.
When a user attempts to access Developer Hub, Developer Hub redirects them to a configured authentication provider, such as Red Hat Build of Keycloak (RHBK), GitHub, or Microsoft Azure. This external IdP is responsible for authenticating the user.
On successful authentication, the Developer Hub authentication plugin, configured in your app-config.yaml file, processes the response from the IdP, resolves the identity in the Developer Hub software catalog, and establishes a user session within Developer Hub.
Configuring authentication and user provisioning is critical for several reasons.
- It secures your Developer Hub instance by ensuring only authenticated users can gain access.
- It enables authorization by allowing you to define access controls based on user and group memberships synchronized from your IdP.
- Provisioning user and group data to the catalog is necessary for various catalog features that rely on understanding entity ownership and relationships between users, groups, and software components. Without this provisioning step, features like displaying who owns a component in the catalog may not function correctly.
To explore Developer Hub features, you can:
- To use Developer Hub without external IdP, enable the guest user to skip configuring authentication and authorization, log in as the guest user, and access all Developer Hub features.
-
To use Developer Hub without authorization policies and features relying on the software catalog, you can enable the
dangerouslyAllowSignInWithoutUserInCatalogresolver option. This setting bypasses the check requiring a user to be in the catalog but still enforces authentication.
Developer Hub uses a one-way synchronization model, where user and group data flow from your Identity Provider to the Developer Hub software catalog. As a result, deleting users or groups manually through the Developer Hub Web UI or REST API might be ineffective or cause inconsistencies, since those entities will be recreated during the next ingestion.
2. Authenticating with the Guest user

3. Authenticating with Red Hat Build of Keycloak (RHBK)
3.1. Enabling user authentication with Red Hat Build of Keycloak (RHBK)
To authenticate users with Red Hat Build of Keycloak (RHBK), enable and configure the OpenID Connect (OIDC) authentication provider in Red Hat Developer Hub and provision the users and groups from RHBK to the Developer Hub software catalog.
Prerequisites
- You added a custom Developer Hub application configuration, and have sufficient permissions to modify it.
- You have sufficient permissions in RHSSO to create and manage a realm and a client. Alternatively, your RHBK administrator can prepare in RHBK the required realm and client for you.
Procedure
To allow Developer Hub to authenticate with RHBK, complete the steps in RHBK, to create a realm and a user and secure the first application:
Use an existing realm, or create a realm, with a distinctive Name such as <my_realm>. Save the value for the next step:
- RHBK realm base URL, such as: <your_rhbk_URL>/realms/<your_realm>.
To register your Developer Hub in RHBK, in the created realm, secure the first application, with:
- Client ID: A distinctive client ID, such as <RHDH>.
-
Valid redirect URIs: Set to the OIDC handler URL:
https://<my_developer_hub_domain>/api/auth/oidc/handler/frame. - Navigate to the Credentials tab and copy the Client secret.
Save the values for the next step:
- Client ID
- Client Secret
- To prepare for the verification steps, in the same realm, get the credential information for an existing user or create a user. Save the user credential information for the verification steps.
To add your RHSSO credentials to Developer Hub, add the following key/value pairs to your Developer Hub secrets. You can use these secrets in the Developer Hub configuration files by using their respective environment variable name.
AUTHENTICATION_OIDC_CLIENT_ID- Enter the saved Client ID.
AUTHENTICATION_OIDC_CLIENT_SECRET- Enter the saved Client Secret.
AUTHENTICATION_OIDC_METADATA_URL- Enter the saved RHBK realm base URL.

To verify RHBK user authentication:
- Go to the Developer Hub login page.
- Your Developer Hub sign-in page displays Sign in using OIDC and the Guest user sign-in is disabled.
- Log in with OIDC by using the saved Username and Password values.
3.2. Creating a custom transformer to provision users from Red Hat Build of Keycloak (RHBK) to the software catalog
To customize how RHBK users and groups are mapped to Red Hat Developer Hub entities, you can create a backend module that uses the keycloakTransformerExtensionPoint to provide custom user and group transformers for the Keycloak backend.
Prerequisites
Procedure
-
Create a new backend module with the
yarn newcommand. Add your custom user and group transformers to the
keycloakTransformerExtensionPoint.The following is an example of how the backend module can be defined:
plugins/<module-name>/src/module.tsimport { GroupTransformer, keycloakTransformerExtensionPoint, UserTransformer, } from '@backstage-community/plugin-catalog-backend-module-keycloak'; const customGroupTransformer: GroupTransformer = async ( entity, // entity output from default parser realm, // Keycloak realm name groups, // Keycloak group representation ) => { /* apply transformations */ return entity; }; const customUserTransformer: UserTransformer = async ( entity, // entity output from default parser user, // Keycloak user representation realm, // Keycloak realm name groups, // Keycloak group representation ) => { /* apply transformations */ return entity; }; export const keycloakBackendModuleTransformer = createBackendModule({ pluginId: 'catalog', moduleId: 'keycloak-transformer', register(reg) { reg.registerInit({ deps: { keycloak: keycloakTransformerExtensionPoint, }, async init({ keycloak }) { keycloak.setUserTransformer(customUserTransformer); keycloak.setGroupTransformer(customGroupTransformer); /* highlight-add-end */ }, }); }, });ImportantThe module’s
pluginIdmust be set tocatalogto match thepluginIdof thekeycloak-backend; otherwise, the module fails to initialize.Install this new backend module into your Developer Hub backend.
backend.add(import(backstage-plugin-catalog-backend-module-keycloak-transformer))
Verification
Developer Hub imports the users and groups each time when started. Check the console logs to verify that the synchronization is completed.
