Chapter 1. New features


This section highlights new features in Red Hat Developer Hub 1.4.

1.1. Added an individual mountPath

This update adds an individual mountPath for extra ConfigMaps or Secrets.

1.2. PersistentVolumeClaims support is available

With this update, PersistentVolumeClaims (PVC) support is available.

1.3. Enhanced use of kube-rbac-proxy

This update removes the kube-rbac-proxy sidecar container from the RHDH Operator Pod. This sidecar container protected the operator metrics endpoint. However, the main container now provides this functionality out-of-the-box. Removing this sidecar container allows for reducing the resources required to run the Operator.

1.4. Identifying Backstage flavor for plugins by using the developerHub.flavor field

With this update, you can use the developerHub.flavor field to identify whether plugins are running on RHDH, RHTAP, or vanilla Backstage, as shown in the following example:

app-config.yaml fragment with the developerhub.flavor field

developerHub:
  flavor: <flavor>

flavor
Identify the flavor of Backstage that is running. Default value: rhdh

1.5. Ability to manage Persistent Volume Claim (PVCs) in RHDH Operator

You can now mount directories from pre-created PersistentVolumeClaims (PVCs) using the spec.application.extraFiles.pvcs field, while configuring RHDH Operator. For more information, see Configuring Red Hat Developer Hub deployment when using the Operator.

1.6. Authenticating with Red Hat Build of Keycloak

With this update, you can use Red Hat Build of Keycloak as an authentication provider. The Keycloak plugin will now support ingesting users and groups with Red Hat Build of Keycloak. For more details, see Authenticating with Red Hat Build of Keycloak.

1.7. Ability to install third-party plugins in RHDH

You can now install third-party plugins in Red Hat Developer Hub without rebuilding the RHDH application.

For more information, see Installing third-party plugins in Red Hat Developer Hub.

1.8. The catalog backend module logs plugin is enabled

With this update, the backstage-plugin-catalog-backend-module-logs is enabled and converted to a static plugin improving performance and stability. The dynamic plugin was disabled in version 1.3.

1.9. Google Kubernetes Engine now supported

Google Kubernetes Engine (GKE) is out of Developer Preview and is now fully supported as of RHDH 1.4.

See the full list of supported platforms on the Life Cycle page.

1.10. Manage concurrent writing when installing dynamic plugins

Previously, running multi-replica RHDH with a Persistent Volume for the Dynamic Plugins cache was not possible due to potential write conflicts. This update mitigates that risk.
