Chapter 6. Customizing the Learning Paths 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 URL must include the /developer-hub/learning-paths proxy. Note Due to the use of overlapping pathRewrites for both the learning-path and homepage quick access proxies, you must create the learning-paths configuration ( ^api/proxy/developer-hub/learning-paths ) 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 Learning Path from the following sources: JSON files hosted on GitHub or GitLab. A dedicated service that provides the Learning Path data in JSON format using an API. 6.1. Using hosted JSON files to provide data to the Learning Paths Prerequisites You have installed Red Hat Developer Hub by using either the Operator or Helm chart. For more information, see Installing Red Hat Developer Hub on OpenShift Container Platform . Procedure To access the data from the JSON files, complete the following step: Add the following code to the app-config.yaml file: proxy: endpoints: '/developer-hub': target: https://raw.githubusercontent.com/ pathRewrite: '^/api/proxy/developer-hub/learning-paths': '/janus-idp/backstage-showcase/main/packages/app/public/learning-paths/data.json' '^/api/proxy/developer-hub/tech-radar': '/janus-idp/backstage-showcase/main/packages/app/public/tech-radar/data-default.json' '^/api/proxy/developer-hub': '/janus-idp/backstage-showcase/main/packages/app/public/homepage/data.json' changeOrigin: true secure: true 6.2. Using a dedicated service to provide data to the Learning Paths 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 You have installed the Red Hat Developer Hub using Helm chart. For more information, see Installing Red Hat Developer Hub on OpenShift Container Platform . Procedure To use a dedicated service to provide the Learning Path data, complete the following steps: Add the following code to the app-config-rhdh.yaml file: proxy: endpoints: # Other Proxies '/developer-hub/learning-paths': target: USD{LEARNING_PATH_DATA_URL} changeOrigin: true # Change to "false" in case of using self hosted cluster with a self-signed certificate secure: true where the LEARNING_PATH_DATA_URL is defined as http://<SERVICE_NAME>/learning-paths , for example, http://rhdh-customization-provider/learning-paths . Note You can define the LEARNING_PATH_DATA_URL by adding it to rhdh-secrets or by directly replacing it with its value in your custom ConfigMap. Delete the Developer Hub pod to ensure that the new configurations are loaded correctly.
