Chapter 9. Customizing the Tech Radar page in Red Hat Developer Hub

Procedure

1. Publish the JSON file containing your Tech Radar data to a web server, such as GitHub or Gitlab. You can find an example at https://raw.githubusercontent.com/redhat-developer/rhdh/release-1.6/packages/app/public/tech-radar/data-default.json.

2. Configure Developer Hub to access the Tech Radar data from the hosted JSON files, by adding the following to the app-config.yaml file:

   techRadar:
     url: <tech_radar_data_url>

   Copy to Clipboard Toggle word wrap

   <tech_radar_data_url>

   Enter the Tech Radar data hosted JSON URL.

Procedure

1. Deploy your Developer Hub customization service on the same OpenShift Container Platform cluster as your Developer Hub instance. You can find an example at red-hat-developer-hub-customization-provider, that provides the same data as default Developer Hub data. The customization service provides a Tech Radar data URL such as: http://<rhdh-customization-provider>/tech-radar.

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

   backend:
      reading:
           allow:
             - host: '<rhdh_customization_provider_base_url>'

   Copy to Clipboard Toggle word wrap

   <rhdh_customization_provider_base_url>

   Enter the base URL of your Tech Radar data URL, such as: <rhdh-customization-provider>.

3. Add the following to the app-config.yaml file:

   techRadar:
       url: <tech_radar_data_url>

   Copy to Clipboard Toggle word wrap

   <tech_radar_data_url>

   Enter your Tech Radar data URL, such as: http://<rhdh-customization-provider>/tech-radar.
