Using dynamic plugins
Abstract
Chapter 1. Using 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.
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 use the Ansible plugins, see Using Ansible plug-ins for Red Hat Developer Hub.
Chapter 2. Using 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
- You have enabled the Argo CD plugin in Red Hat Developer Hub RHDH.
Procedures
- Select the Catalog tab and choose the component that you want to use.
Select the CD tab to view insights into deployments managed by Argo CD.
Select an appropriate card to view the deployment details (for example, commit message, author name, and deployment history).
-
Click the link icon (
) to open the deployment details in Argo CD.
-
Click the link icon (
Select the Overview tab and navigate to the Deployment summary section to review the summary of your application’s deployment across namespaces. Additionally, select an appropriate Argo CD app to open the deployment details in Argo CD, or select a commit ID from the Revision column to review the changes in GitLab or GitHub.

Chapter 3. Using Keycloak
The Keycloak backend plugin, which integrates Keycloak into Developer Hub, has the following capabilities:
- Synchronization of Keycloak users in a realm.
- Synchronization of Keycloak groups and their users in a realm.
3.1. Importing users and groups in Developer Hub using the Keycloak plugin
After configuring the plugin successfully, the plugin imports the users and groups each time when started.
If you set up a schedule, users and groups will also be imported.
After the first import is complete, you can select User to list the users from the catalog page:
You can see the list of users on the page:
When you select a user, you can see the information imported from Keycloak:
You can also select a group, view the list, and select or view the information imported from Keycloak for a group:
Chapter 4. Using the Nexus Repository Manager plugin
The Nexus Repository Manager plugin displays the information about your build artifacts in your Developer Hub application. The build artifacts are available in the Nexus Repository Manager.
The Nexus Repository Manager plugin is 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.
The Nexus Repository Manager is a front-end plugin that enables you to view the information about build artifacts.
Prerequisites
- Your Developer Hub application is installed and running.
- You have installed the Nexus Repository Manager plugin.
Procedure
- Open your Developer Hub application and select a component from the Catalog page.
Go to the BUILD ARTIFACTS tab.
The BUILD ARTIFACTS tab contains a list of build artifacts and related information, such as VERSION, REPOSITORY, REPOSITORY TYPE, MANIFEST, MODIFIED, and SIZE.
Chapter 5. Using 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.
You can use the Tekton front-end plugin to view PipelineRun resources.
Prerequisites
- You have installed the Red Hat Developer Hub (RHDH).
- You have installed the Tekton plugin. For the installation process, see Installing and configuring the Tekton plugin.
Procedure
- Open your RHDH application and select a component from the Catalog page.
Go to the CI tab.
The CI tab displays the list of PipelineRun resources associated with a Kubernetes cluster. The list contains pipeline run details, such as NAME, VULNERABILITIES, STATUS, TASK STATUS, STARTED, and DURATION.
Click the expand row button besides PipelineRun name in the list to view the PipelineRun visualization. The pipeline run resource includes tasks to complete. When you hover the mouse pointer on a task card, you can view the steps to complete that particular task.
Chapter 6. Using the Topology plugin
Topology is a front-end plugin that enables you to view the workloads as nodes that power any service on the Kubernetes cluster.
Prerequisites
- You have installed the Red Hat Developer Hub (RHDH).
- You have installed the Topology plugin.
If the RBAC permission framework is enabled, ensure to add the following permission policies in an external permission policies configuration file named
rbac-policy.csvto allow the RBAC admins or your desired user(s)/group(s) to access the Topology plugin:g, user:default/<YOUR_USERNAME>, role:default/topology-viewer p, role:default/topology-viewer, topology.view.read, read, allow p, role:default/topology-viewer, kubernetes.proxy, use, allow p, role:default/topology-viewer, catalog-entity, read, allow p, role:default/topology-viewer, topology.view.read, read, allow grants the user the ability to see the Topology panel. p, role:default/topology-viewer, kubernetes.proxy, use, allow grants the user the ability to view the pod logs. p, role:default/topology-viewer, catalog-entity, read, allow grants the user the ability to see the catalog item.
Procedure
- Open your RHDH application and select a component from the Catalog page.
Go to the TOPOLOGY tab and you can view the workloads such as deployments or pods as nodes.
- Select a node and a pop-up appears on the right side, which contains two tabs: Details and Resources.
The Details and Resources tabs contain the associated information and resources of the node.
Click on the Open URL button on the top of a node.
When you click on the Open URL button, it allows you to access the associated Ingresses and runs your application in a new tab.
