Notifications

Previously we created a component based on a Software Template. There is a way to create a relationship between the component and the software template to track the changes along the time. This process requires enable the backstage-community-plugin-catalog-backend-module-scaffolder-relation-processor-dynamic plugin to add the spec.scaffoldedFrom property into the catalog definition. Having that property Red Hat Developer Hub will visualize the relationship between both entities.

Additionally we can enable notifications when a new version of the template is deployed, so, we can track that our component was created from a previous version. It can be very helpful to review the new version of the template and apply some changes into our current version of the component. To enable notifications the backstage-plugin-notifications and backstage-plugin-notifications-backend-dynamic must be enabled.

Run:

To verify the dependency between components and templates, let’s create a new component using the sample template as we did previously in this exercise. After its creation verify that the spec.scaffolderFrom exists in the catalog-info.yaml file generated, and we can see the relationship in the Dependencies tab of the component.
