Configuring dynamic plugins

Chapter 1. Installing Ansible plug-ins for Red Hat Developer Hub

Ansible plug-ins for Red Hat Developer Hub deliver an Ansible-specific portal experience with curated learning paths, push-button content creation, integrated development tools, and other opinionated resources.

Important

The Ansible plug-ins are a Technology Preview feature only.

Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend using them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information on Red Hat Technology Preview features, see Technology Preview Features Scope.

Additional detail on how Red Hat provides support for bundled community dynamic plugins is available on the Red Hat Developer Support Policy page.

To install and configure the Ansible plugins, see Installing Ansible plug-ins for Red Hat Developer Hub.

Chapter 2. Enabling the Argo CD plugin

You can use the Argo CD plugin to visualize the Continuous Delivery (CD) workflows in OpenShift GitOps. This plugin provides a visual overview of the application’s status, deployment details, commit message, author of the commit, container image promoted to environment and deployment history.

Prerequisites

Add Argo CD instance information to your app-config.yaml configmap as shown in the following example:

argocd:
  appLocatorMethods:
    - type: 'config'
      instances:
        - name: argoInstance1
          url: https://argoInstance1.com
          username: ${ARGOCD_USERNAME}
          password: ${ARGOCD_PASSWORD}
        - name: argoInstance2
          url: https://argoInstance2.com
          username: ${ARGOCD_USERNAME}
          password: ${ARGOCD_PASSWORD}

Add the following annotation to the entity’s catalog-info.yaml file to identify the Argo CD applications.

annotations:
  ...
  # The label that Argo CD uses to fetch all the applications. The format to be used is label.key=label.value. For example, rht-gitops.com/janus-argocd=quarkus-app.

  argocd/app-selector: '${ARGOCD_LABEL_SELECTOR}'

(Optional) Add the following annotation to the entity’s catalog-info.yaml file to switch between Argo CD instances as shown in the following example:
```
 annotations:
   ...
    # The Argo CD instance name used in `app-config.yaml`.

    argocd/instance-name: '${ARGOCD_INSTANCE}'
```
Note
If you do not set this annotation, the Argo CD plugin defaults to the first Argo CD instance configured in app-config.yaml.

Procedure

Add the following to your dynamic-plugins ConfigMap to enable the Argo CD plugin.

global:
  dynamic:
    includes:
      - dynamic-plugins.default.yaml
    plugins:
      - package: ./dynamic-plugins/dist/roadiehq-backstage-plugin-argo-cd-backend-dynamic
        disabled: false
      - package: ./dynamic-plugins/dist/backstage-community-plugin-redhat-argocd
        disabled: false

Additional resources

The package path, scope, and name of the Red Hat ArgoCD plugin has changed since 1.2. For more information, see Breaking Changes in the Release notes for Red Hat Developer Hub.

Schedule configuration

You can configure a schedule in the app-config.yaml file, as follows:

     catalog:
       providers:
         keycloakOrg:
           default:
             # ...
             # highlight-add-start
             schedule: # optional; same options as in TaskScheduleDefinition
               # supports cron, ISO duration, "human duration" as used in code
               frequency: { minutes: 1 }
               # supports ISO duration, "human duration" as used in code
               timeout: { minutes: 1 }
               initialDelay: { seconds: 15 }
               # highlight-add-end

Note

If you have made any changes to the schedule in the app-config.yaml file, then restart to apply the changes.

Keycloak query parameters

You can override the default Keycloak query parameters in the app-config.yaml file, as follows:

   catalog:
     providers:
       keycloakOrg:
         default:
           # ...
           # highlight-add-start
           userQuerySize: 500 # Optional
           groupQuerySize: 250 # Optional
           # highlight-add-end

Communication between Developer Hub and Keycloak is enabled by using the Keycloak API. Username and password, or client credentials are supported authentication methods.

The following table describes the parameters that you can configure to enable the plugin under catalog.providers.keycloakOrg.<ENVIRONMENT_NAME> object in the app-config.yaml file:

Name	Description	Default Value	Required
`baseUrl`	Location of the Keycloak server, such as `https://localhost:8443/auth`. Note that the newer versions of Keycloak omit the `/auth` context path.	""	Yes
`realm`	Realm to synchronize	`master`	No
`loginRealm`	Realm used to authenticate	`master`	No
`username`	Username to authenticate	""	Yes if using password based authentication
`password`	Password to authenticate	""	Yes if using password based authentication
`clientId`	Client ID to authenticate	""	Yes if using client credentials based authentication
`clientSecret`	Client Secret to authenticate	""	Yes if using client credentials based authentication
`userQuerySize`	Number of users to query at a time	`100`	No
`groupQuerySize`	Number of groups to query at a time	`100`	No

When using client credentials, the access type must be set to confidential and service accounts must be enabled. You must also add the following roles from the realm-management client role:

query-groups
query-users
view-users

3.4. Limitations

If you have self-signed or corporate certificate issues, you can set the following environment variable before starting Developer Hub:

NODE_TLS_REJECT_UNAUTHORIZED=0

Note

The solution of setting the environment variable is not recommended.

Chapter 5. Installing and configuring the Tekton plugin

You can use the Tekton plugin to visualize the results of CI/CD pipeline runs on your Kubernetes or OpenShift clusters. The plugin allows users to visually see high level status of all associated tasks in the pipeline for their applications.

5.1. Installation

Prerequsites

You have installed and configured the @backstage/plugin-kubernetes and @backstage/plugin-kubernetes-backend dynamic plugins.
You have configured the Kubernetes plugin to connect to the cluster using a ServiceAccount.
The ClusterRole must be granted for custom resources (PipelineRuns and TaskRuns) to the ServiceAccount accessing the cluster.
Note
If you have the RHDH Kubernetes plugin configured, then the ClusterRole is already granted.
To view the pod logs, you have granted permissions for pods/log.

You can use the following code to grant the ClusterRole for custom resources and pod logs:

kubernetes:
   ...
   customResources:
     - group: 'tekton.dev'
       apiVersion: 'v1'
       plural: 'pipelineruns'
     - group: 'tekton.dev'
       apiVersion: 'v1'


 ...
  apiVersion: rbac.authorization.k8s.io/v1
  kind: ClusterRole
  metadata:
    name: backstage-read-only
  rules:
    - apiGroups:
        - ""
      resources:
        - pods/log
      verbs:
        - get
        - list
        - watch
    ...
    - apiGroups:
        - tekton.dev
      resources:
        - pipelineruns
        - taskruns
      verbs:
        - get
        - list

You can use the prepared manifest for a read-only ClusterRole, which provides access for both Kubernetes plugin and Tekton plugin.

Add the following annotation to the entity’s catalog-info.yaml file to identify whether an entity contains the Kubernetes resources:
```
annotations:
  ...

  backstage.io/kubernetes-id: <BACKSTAGE_ENTITY_NAME>
```
You can also add the backstage.io/kubernetes-namespace annotation to identify the Kubernetes resources using the defined namespace.
```
annotations:
  ...

  backstage.io/kubernetes-namespace: <RESOURCE_NS>
```
Add the following annotation to the catalog-info.yaml file of the entity to enable the Tekton related features in RHDH. The value of the annotation identifies the name of the RHDH entity:
```
annotations:
  ...

  janus-idp.io/tekton : <BACKSTAGE_ENTITY_NAME>
```
Add a custom label selector, which RHDH uses to find the Kubernetes resources. The label selector takes precedence over the ID annotations.
```
annotations:
  ...

  backstage.io/kubernetes-label-selector: 'app=my-app,component=front-end'
```
Add the following label to the resources so that the Kubernetes plugin gets the Kubernetes resources from the requested entity:
```
labels:
  ...

  backstage.io/kubernetes-id: <BACKSTAGE_ENTITY_NAME>
```
Note
When you use the label selector, the mentioned labels must be present on the resource.

Procedure

The Tekton plugin is pre-loaded in RHDH with basic configuration properties. To enable it, set the disabled property to false as follows:

global:
  dynamic:
    includes:
      - dynamic-plugins.default.yaml
    plugins:
      - package: ./dynamic-plugins/dist/janus-idp-backstage-plugin-tekton
        disabled: false

Chapter 6. Installing and configuring the Topology plugin

6.1. Installation

The Topology plugin enables you to visualize the workloads such as Deployment, Job, Daemonset, Statefulset, CronJob, Pods and Virtual Machines powering any service on your Kubernetes cluster.

Prerequisites

You have installed and configured the @backstage/plugin-kubernetes-backend dynamic plugins.
You have configured the Kubernetes plugin to connect to the cluster using a ServiceAccount.
The ClusterRole must be granted to ServiceAccount accessing the cluster.
Note
If you have the Developer Hub Kubernetes plugin configured, then the ClusterRole is already granted.

Procedure

The Topology plugin is pre-loaded in Developer Hub with basic configuration properties. To enable it, set the disabled property to false as follows:

app-config.yaml fragment

auth:
global:
  dynamic:
    includes:
      - dynamic-plugins.default.yaml
    plugins:
      - package: ./dynamic-plugins/dist/janus-idp-backstage-plugin-topology
        disabled: false

6.2. Configuration

6.2.1. Viewing OpenShift routes

To view OpenShift routes, you must grant read access to the routes resource in the Cluster Role:

  apiVersion: rbac.authorization.k8s.io/v1
  kind: ClusterRole
  metadata:
    name: backstage-read-only
  rules:
    ...
    - apiGroups:

      resources:
        - routes
      verbs:
        - get
        - list

You must also add the following in kubernetes.customResources property in your app-config.yaml file:

kubernetes:
    ...
    customResources:
      - group: 'route.openshift.io'
        apiVersion: 'v1'
        	  plural: 'routes'

6.2.2. Viewing pod logs

        - pods/log
      verbs:
        - get
        - list
        - watch

6.2.3. Viewing Tekton PipelineRuns

To view the Tekton PipelineRuns you must grant read access to the pipelines, pipelinesruns, and taskruns resources in the ClusterRole:

 ...
  apiVersion: rbac.authorization.k8s.io/v1
  kind: ClusterRole
  metadata:
    name: backstage-read-only
  rules:
    ...
    - apiGroups:

        - pipelineruns
        - taskruns
      verbs:
        - get
        - list

To view the Tekton PipelineRuns list in the side panel and the latest PipelineRuns status in the Topology node decorator, you must add the following code to the kubernetes.customResources property in your app-config.yaml file:

kubernetes:
    ...
    customResources:
      - group: 'tekton.dev'
        apiVersion: 'v1'
        plural: 'pipelines'

        plural: 'pipelineruns'
      - group: 'tekton.dev'
        apiVersion: 'v1'
        plural: 'taskruns'

6.2.4. Viewing virtual machines

To view virtual machines, the OpenShift Virtualization operator must be installed and configured on a Kubernetes cluster. You must also grant read access to the VirtualMachines resource in the ClusterRole:

 ...
  apiVersion: rbac.authorization.k8s.io/v1
  kind: ClusterRole
  metadata:
    name: backstage-read-only
  rules:
    ...
    - apiGroups:
        - kubevirt.io
      resources:
        - virtualmachines
        - virtualmachineinstances
      verbs:
        - get
        - list

To view the virtual machine nodes on the topology plugin, you must add the following code to the kubernetes.customResources property in the app-config.yaml file:

kubernetes:
    ...
    customResources:
      - group: 'kubevirt.io'
        apiVersion: 'v1'
        plural: 'virtualmachines'
      - group: 'kubevirt.io'
        apiVersion: 'v1'
        plural: 'virtualmachineinstances'

6.2.5. Enabling the source code editor

To enable the source code editor, you must grant read access to the CheClusters resource in the ClusterRole as shown in the following example code:

 ...
  apiVersion: rbac.authorization.k8s.io/v1
  kind: ClusterRole
  metadata:
    name: backstage-read-only
  rules:
    ...
    - apiGroups:
        - org.eclipse.che
      resources:
        - checlusters
      verbs:
        - get
        - list

To use the source code editor, you must add the following configuration to the kubernetes.customResources property in your app-config.yaml file:

 kubernetes:
    ...
    customResources:
      - group: 'org.eclipse.che'
        apiVersion: 'v2'
        plural: 'checlusters'

6.2.6. Labels and annotations

6.2.6.1. Linking to the source code editor or the source

Add the following annotations to workload resources, such as Deployments to navigate to the Git repository of the associated application using the source code editor:

annotations:
  app.openshift.io/vcs-uri: <GIT_REPO_URL>

Add the following annotation to navigate to a specific branch:

annotations:
  app.openshift.io/vcs-ref: <GIT_REPO_BRANCH>

Note

If Red Hat OpenShift Dev Spaces is installed and configured and git URL annotations are also added to the workload YAML file, then clicking on the edit code decorator redirects you to the Red Hat OpenShift Dev Spaces instance.

Note

When you deploy your application using the OCP Git import flows, then you do not need to add the labels as import flows do that. Otherwise, you need to add the labels manually to the workload YAML file.

You can also add the app.openshift.io/edit-url annotation with the edit URL that you want to access using the decorator.

6.2.6.2. Entity annotation/label

For RHDH to detect that an entity has Kubernetes components, add the following annotation to the entity’s catalog-info.yaml:

annotations:
  backstage.io/kubernetes-id: <BACKSTAGE_ENTITY_NAME>

The following label is added to the resources so that the Kubernetes plugin gets the Kubernetes resources from the requested entity, add the following label to the resources:

labels:
  backstage.io/kubernetes-id: <BACKSTAGE_ENTITY_NAME>`

Note

When using the label selector, the mentioned labels must be present on the resource.

6.2.6.3. Namespace annotation

To identify the Kubernetes resources using the defined namespace, add the backstage.io/kubernetes-namespace annotation:

annotations:
  backstage.io/kubernetes-namespace: <RESOURCE_NS>

The Red Hat OpenShift Dev Spaces instance is not accessible using the source code editor if the backstage.io/kubernetes-namespace annotation is added to the catalog-info.yaml file.

To retrieve the instance URL, you require the CheCluster Custom Resource (CR). As the CheCluster CR is created in the openshift-devspaces namespace, the instance URL is not retrieved if the namespace annotation value is not openshift-devspaces.

6.2.6.4. Label selector query annotation

You can write your own custom label, which RHDH uses to find the Kubernetes resources. The label selector takes precedence over the ID annotations:

annotations:
  backstage.io/kubernetes-label-selector: 'app=my-app,component=front-end'

If you have multiple entities while Red Hat Dev Spaces is configured and want multiple entities to support the edit code decorator that redirects to the Red Hat Dev Spaces instance, you can add the backstage.io/kubernetes-label-selector annotation to the catalog-info.yaml file for each entity.

annotations:
  backstage.io/kubernetes-label-selector: 'component in (<BACKSTAGE_ENTITY_NAME>,che)'

If you are using the previous label selector, you must add the following labels to your resources so that the Kubernetes plugin gets the Kubernetes resources from the requested entity:

labels:
  component: che # add this label to your che cluster instance
labels:
  component: <BACKSTAGE_ENTITY_NAME> # add this label to the other resources associated with your entity

You can also write your own custom query for the label selector with unique labels to differentiate your entities. However, you need to ensure that you add those labels to the resources associated with your entities including your CheCluster instance.

6.2.6.5. Icon displayed in the node

To display a runtime icon in the topology nodes, add the following label to workload resources, such as Deployments:

labels:
  app.openshift.io/runtime: <RUNTIME_NAME>

Alternatively, you can include the following label to display the runtime icon:

labels:
  app.kubernetes.io/name: <RUNTIME_NAME>

Supported values of <RUNTIME_NAME> include:

django
dotnet
drupal
go-gopher
golang
grails
jboss
jruby
js
nginx
nodejs
openjdk
perl
phalcon
php
python
quarkus
rails
redis
rh-spring-boot
rust
java
rh-openjdk
ruby
spring
spring-boot

Note

Other values result in icons not being rendered for the node.

6.2.6.6. App grouping

To display workload resources such as deployments or pods in a visual group, add the following label:

labels:
  app.kubernetes.io/part-of: <GROUP_NAME>

6.2.6.7. Node connector

To display the workload resources such as deployments or pods with a visual connector, add the following annotation:

annotations:
  app.openshift.io/connects-to: '[{"apiVersion": <RESOURCE_APIVERSION>,"kind": <RESOURCE_KIND>,"name": <RESOURCE_NAME>}]'

For more information about the labels and annotations, see Guidelines for labels and annotations for OpenShift applications.

Chapter 7. Bulk importing GitHub repositories

Important

These features are for Technology Preview only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend using them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information on Red Hat Technology Preview features, see Technology Preview Features Scope.

Red Hat Developer Hub can automate GitHub repositories onboarding and track their import status.

7.1. Enabling and giving access to the Bulk Import feature

You can enable the Bulk Import feature for users and give them the necessary permissions to access it.

Prerequisites

You have configured GitHub integration.

Procedure

The Bulk Import plugins are installed but disabled by default. To enable the ./dynamic-plugins/dist/janus-idp-backstage-plugin-bulk-import-backend-dynamic and ./dynamic-plugins/dist/janus-idp-backstage-plugin-bulk-import plugins, edit your dynamic-plugins.yaml with the following content:
dynamic-plugins.yaml fragment
```
plugins:
  - package: ./dynamic-plugins/dist/janus-idp-backstage-plugin-bulk-import-backend-dynamic
    disabled: false
  - package: ./dynamic-plugins/dist/janus-idp-backstage-plugin-bulk-import
    disabled: false
```
See Installing and viewing dynamic plugins.
Configure the required bulk.import RBAC permission for the users who are not administrators as follows:
rbac-policy.csv fragment
```
p, role:default/bulk-import, bulk.import, use, allow
g, user:default/<your_user>, role:default/bulk-import
```
Note that only Developer Hub administrators or users with the bulk.import permission can use the Bulk Import feature. See Permission policies in Red Hat Developer Hub.

Verification

The sidebar displays a Bulk Import option.
The Bulk Import page shows a list of Added Repositories.

7.2. Importing multiple GitHub repositories

In Red Hat Developer Hub, you can select your GitHub repositories and automate their onboarding to the Developer Hub catalog.

Prerequisites

You have enabled the Bulk Import feature and gave access to it.

Procedure

Click Bulk Import in the left sidebar.
Click the Add button in the top-right corner to see the list of all repositories accessible from the configured GitHub integrations.
1. From the Repositories view, you can select any repository, or search for any accessible repositories. For each repository selected, a catalog-info.yaml is generated.
2. From the Organizations view, you can select any organization by clicking Select in the third column. This option allows you to select one or more repositories from the selected organization.
Click Preview file to view or edit the details of the pull request for each repository.
1. Review the pull request description and the catalog-info.yaml file content.
2. Optional: when the repository has a .github/CODEOWNERS file, you can select the Use CODEOWNERS file as Entity Owner checkbox to use it, rather than having the content-info.yaml contain a specific entity owner.
3. Click Save.
Click Create pull requests. At this point, a set of dry-run checks runs against the selected repositories to ensure they meet the requirements for import, such as:
1. Verifying that there is no entity in the Developer Hub catalog with the name specified in the repository catalog-info.yaml
2. Verifying that the repository is not empty
3. Verifying that the repository contains a .github/CODEOWNERS file if the Use CODEOWNERS file as Entity Owner checkbox is selected for that repository
  - If any errors occur, the pull requests are not created, and you see a Failed to create PR error message detailing the issues. To view more details about the reasons, click Edit.
  - If there are no errors, the pull requests are created, and you are redirected to the list of added repositories.
Review and merge each pull request that creates a catalog-info.yml file.

Verification

The Added repositories list displays the repositories you imported, each with an appropriate status: either Waiting for approval or Added.
For each Waiting for approval import job listed, there is a corresponding pull request adding the catalog-info.yaml file in the corresponding repository.

7.3. Managing the added repositories

You can oversee and manage the repositories that are imported to the Developer Hub.

Prerequisites

You have imported GitHub repositories.

Procedure

Click Bulk Import in the left sidebar to display all the current repositories that are being tracked as Import jobs, along with their status.
Added
The repository is added to the Developer Hub catalog after the import pull request is merged or if the repository already contained a catalog-info.yaml file during the bulk import. Note that it may take a few minutes for the entities to be available in the catalog.
Waiting for approval
There is an open pull request adding a catalog-info.yaml file to the repository. You can:
Click the pencil icon on the right to see details about the pull request or edit the pull request content right from Developer Hub.
Delete the Import job, this action closes the import PR as well.
To transition the Import job to the Added state, merge the import pull request from the Git repository.
Empty
Developer Hub is unable to determine the import job status because the repository is imported from other sources but does not have a catalog-info.yaml file and lacks any import pull request adding it.

Note

After an import pull request is merged, the import status is marked as Added in the list of Added Repositories, but it might take a few seconds for the corresponding entities to appear in the Developer Hub Catalog.
A location added through other sources (like statically in an app-config.yaml file, dynamically when enabling GitHub discovery, or registered manually using the "Register an existing component" page) might show up in the Bulk Import list of Added Repositories if the following conditions are met:
- The target repository is accessible from the configured GitHub integrations.
- The location URL points to a catalog-info.yaml file at the root of the repository default branch.

7.4. Understanding the Bulk Import audit Logs

The Bulk Import backend plugin adds the following events to the Developer Hub audit logs. See Audit Logs in Red Hat Developer Hub for more information on how to configure and view audit logs.

Bulk Import Events:

BulkImportUnknownEndpoint: Tracks requests to unknown endpoints.

Chapter 8. ServiceNow Custom actions in Red Hat Developer Hub

Important

These features are for Technology Preview only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend using them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information on Red Hat Technology Preview features, see Technology Preview Features Scope.

In Red Hat Developer Hub, you can access ServiceNow custom actions (custom actions) for fetching and registering resources in the catalog.

The custom actions in Developer Hub enable you to facilitate and automate the management of records. Using the custom actions, you can perform the following actions:

Create, update, or delete a record
Retrieve information about a single record or multiple records

8.1. Enabling ServiceNow custom actions plugin in Red Hat Developer Hub

In Red Hat Developer Hub, the ServiceNow custom actions are provided as a pre-loaded plugin, which is disabled by default. You can enable the custom actions plugin using the following procedure.

Prerequisites

Red Hat Developer Hub is installed and running. For more information about installing the Developer Hub, see Installing Red Hat Developer Hub on OpenShift Container Platform with the Helm chart.
You have created a project in the Developer Hub.

Procedure

To activate the custom actions plugin, add a package with plugin name and update the disabled field in your Helm Chart as follows:
```
global:
  dynamic:
    includes:
      - dynamic-plugins.default.yaml
    plugins:
      - package: ./dynamic-plugins/dist/janus-idp-backstage-scaffolder-backend-module-servicenow-dynamic
        disabled: false
```
Note
The default configuration for a plugin is extracted from the dynamic-plugins.default.yaml file, however, you can use a pluginConfig entry to override the default configuration.

Set the following variables in the Helm Chart to access the custom actions:

servicenow:
  # The base url of the ServiceNow instance.
  baseUrl: ${SERVICENOW_BASE_URL}
  # The username to use for authentication.
  username: ${SERVICENOW_USERNAME}
  # The password to use for authentication.
  password: ${SERVICENOW_PASSWORD}

8.2. Supported ServiceNow custom actions in Red Hat Developer Hub

The ServiceNow custom actions enable you to manage records in the Red Hat Developer Hub. The custom actions support the following HTTP methods for API requests:

GET: Retrieves specified information from a specified resource endpoint
POST: Creates or updates a resource
PUT: Modify a resource
PATCH: Updates a resource
DELETE: Deletes a resource

Chapter 9. Overriding Core Backend Service Configuration

The Red Hat Developer Hub (RHDH) backend platform consists of a number of core services that are well encapsulated. The RHDH backend installs these default core services statically during initialization.

You can configure these core services by customizing the backend source code and rebuilding your Developer Hub application. Alternatively, you can customize a core service by installing it as a BackendFeature by using dynamic plugin functionality.

To use the dynamic plugin functionality to customize a core service in your RHDH application, you must configure the backend to avoid statically installing a given default core service.

For example, adding a middleware function to handle all incoming requests can be done by installing a custom configure function for the root HTTP router backend service which allows access to the underlying Express application.

Example of a BackendFeature middleware function to handle incoming HTTP requests

// Create the BackendFeature
export const customRootHttpServerFactory: BackendFeature =
  rootHttpRouterServiceFactory({
    configure: ({ app, routes, middleware, logger }) => {
      logger.info(
        'Using custom root HttpRouterServiceFactory configure function',
      );
      app.use(middleware.helmet());
      app.use(middleware.cors());
      app.use(middleware.compression());
      app.use(middleware.logging());
      // Add a the custom middleware function before all
      // of the route handlers
      app.use(addTestHeaderMiddleware({ logger }));
      app.use(routes);
      app.use(middleware.notFound());
      app.use(middleware.error());
    },
  });

// Export the BackendFeature as the default entrypoint
export default customRootHttpServerFactory;

In the above example, as the BackendFeature overrides the default implementation of the HTTP router service, you must set the ENABLE_CORE_ROOTHTTPROUTER_OVERRIDE environment variable to true so that the Developer Hub does not install the default implementation automatically.

9.1. Overriding environment variables

To allow a dynamic plugin to load a core service override, you must start the Developer Hub backend with the corresponding core service ID environment variable set to true.

Table 9.1. Environment variables and core service IDs
Variable	Description
`ENABLE_CORE_AUTH_OVERRIDE`	Override the `core.auth` service
`ENABLE_CORE_CACHE_OVERRIDE`	Override the `core.cache` service
`ENABLE_CORE_ROOTCONFIG_OVERRIDE`	Override the `core.rootConfig` service
