Tanzu Application Platform Organization Catalog integration

In this topic, you will learn how to add a Spring Cloud Gateway for Kubernetes as a component of your Organization Catalog.

There are two primary scenarios:

• Adding Spring Cloud Gateway to a running component
• Adding Spring Cloud Gateway as a new component

Adding Spring Cloud Gateway to a component

To add the Gateway instance to a running component, you must first add the labels as shown in the following example.

apiVersion: "tanzu.vmware.com/v1"
kind: SpringCloudGateway
metadata:
  name: animal-rescue-gateway
  namespace: animal-rescue
  labels:
    app.kubernetes.io/part-of={PART_OF}

Take care to match the PART_OF to the name of the label app.kubernetes.io/part-of in your component.

Once applied, the gateway pods will be visible in the list of resources.

Adding Spring Cloud Gateway as a new component

To present the Gateway as an independent component:

1. Add the labels described earlier, and you must match the part-of value with the one used in your component, as shown in the following example.

   apiVersion: backstage.io/v1alpha1
   kind: Component
   metadata:
     name: my-gateway
     description: My application gateway
     annotations:
       'backstage.io/kubernetes-label-selector': 'app.kubernetes.io/part-of={PART_OF}'
   spec:
     type: service
     lifecycle: experimental
     owner: default-team
   

2. Then, click Registry Entity at the top of the Catalog view and provide a IRL that points to the component descriptor file. This will make the new component visible in the Catalog view.
