Chapter 5. Customizing the Tech Radar page in the Red Hat Developer Hub

• Using JSON files that are hosted or GitHub or GitLab. To access the data from the JSON files, you can add the following code in the app-config.yaml file:

  proxy:
    endpoints:
      # Other Proxies
      # customize developer hub instance
      '/developer-hub':
        target: <DOMAIN_URL> # i.e https://raw.githubusercontent.com/
        pathRewrite:
          '^/api/proxy/developer-hub/tech-radar': <path to json file> # i.e /janus-idp/backstage-showcase/main/packages/app/public/tech-radar/data-default.json
  	 '^/api/proxy/developer-hub': <path to json file> # i.e /janus-idp/backstage-showcase/main/packages/app/public/homepage/data.json
        changeOrigin: true
        secure: true
  
        # Change to "false" in case of using self hosted cluster with a self-signed certificate
        headers:
  	<HEADER_KEY>: <HEADER_VALUE> # optional and can be passed as needed i.e Authorization can be passed for private GitHub repo and PRIVATE-TOKEN can be passed for private GitLab repo

  Note

  As overlapping exist between the pathRewrites that are used for the tech-radar and homepage quick access proxies, the configuration for the tech-radar (^api/proxy/developer-hub/tech-radar) must exist before the configuration for the homepage (^/api/proxy/developer-hub).

  For more information about customizing the Home page in Red Hat Developer Hub, see Chapter 4, Customizing the Home page in Red Hat Developer Hub.

• Using a separate service that provides the Tech Radar data in JSON format using an API.

Prerequisites

• You have installed the Red Hat Developer Hub using Helm Chart. For more information, see Chapter 2, Installing Red Hat Developer Hub.
