Chapter 7. Customizing the Tech Radar page in Red Hat Developer Hub


In Red Hat Developer Hub, the Tech Radar page is provided by the tech-radar dynamic plugin, which is disabled by default. For information about enabling dynamic plugins in Red Hat Developer Hub see Configuring plugins in Red Hat Developer Hub.

In Red Hat Developer Hub, you can configure Learning Paths by passing the data into the app-config.yaml file as a proxy. The base Tech Radar URL must include the /developer-hub/tech-radar proxy.

Note

Due to the use of overlapping pathRewrites for both the tech-radar and homepage quick access proxies, you must create the tech-radar configuration (^api/proxy/developer-hub/tech-radar) before you create the homepage configuration (^/api/proxy/developer-hub).

For more information about customizing the Home page in Red Hat Developer Hub, see Customizing the Home page in Red Hat Developer Hub.

You can provide data to the Tech Radar page from the following sources:

  • JSON files hosted on GitHub or GitLab.
  • A dedicated service that provides the Tech Radar data in JSON format using an API.

7.1. Using hosted JSON files to provide data to the Tech Radar page

Prerequisites

Procedure

To access the data from the JSON files, complete the following step:

  1. Enable the ./dynamic-plugins/dist/backstage-community-plugin-tech-radar and /dynamic-plugins/dist/backstage-community-plugin-tech-radar-backend-dynamic plugins.
  2. Add the following code to the app-config.yaml file:

    techRadar:
        url: ${TECH_RADAR_DATA_URL} 1
    1
    TECH_RADAR_DATA_URL is the URL from which the JSON data is loaded.

7.2. Using a dedicated service to provide data to the Tech Radar page

When using a dedicated service, you can do the following:

  • Use the same service to provide the data to all configurable Developer Hub pages or use a different service for each page.
  • Use the red-hat-developer-hub-customization-provider as an example service, which provides data for both the Home and Tech Radar pages. The red-hat-developer-hub-customization-provider service provides the same data as default Developer Hub data. You can fork the red-hat-developer-hub-customization-provider service repository from GitHub and modify it with your own data, if required.
  • Deploy the red-hat-developer-hub-customization-provider service and the Developer Hub Helm chart on the same cluster.

Prerequisites

Procedure

To use a separate service to provide the Tech Radar data, complete the following steps:

  1. Add the dedicated service as an allowed host by adding the following code to the app-config.yaml file:

    backend:
       reading:
            allow:
              - host: 'hostname'
  2. Add the following to the app-config.yaml file:

    techRadar:
        url: ${TECH_RADAR_DATA_URL} 1
    1
    TECH_RADAR_DATA_URL is the URL from which the JSON data is loaded.
