Install API Auto Registration

This topic describes how you can install API Auto Registration from the Tanzu Application Platform package repository.

Note
Follow the steps in this topic if you do not want to use a profile to install API Auto Registration. For more information about profiles, see Components and installation profiles.

Tanzu Application Platform prerequisites

Before installing API Auto Registration, complete all prerequisites to install Tanzu Application Platform. See Tanzu Application Platform Prerequisites.

Using with TLS

Starting in Tanzu Application Platform v1.4, TLS is turned on by default for several components. API Auto Registration automatically trusts the CA for the shared ingress_issuer when using the default ClusterIssuer tap-ingress-selfsigned. This change means that a Certificate is automatically generated using this issuer.

If you do not want a Certificate to generate automatically, you can set the auto_generate_cert flag to false in the values file. To replace the default with a custom ingress issuer, see Security and compliance. Whenever you do not use the default ClusterIssuer tap-ingress-selfsigned, do not automatically generate certificates, or use other custom CAs, you must manually set the certificate. See Troubleshooting.

Install

To install the API Auto Registration package:

List version information for the package by running:

Locate the Tanzu Developer Portal (formerly Tanzu Application Platform GUI) URL.

When running on a full profile Tanzu Application Platform cluster, the default value of Tanzu Developer Portal URL is sufficient. You can edit this to match the externally available FQDN of Tanzu Developer Portal to display the entity URL in the externally accessible APIDescriptor status.

When installed in a run cluster or with a profile where Tanzu Developer Portal is not installed in the same cluster, you must set the tap_gui_url parameters correctly for successful entity registration with Tanzu Developer Portal.

You can locate the tap_gui_url by going to the view cluster with the Tanzu Developer Portal you want to register the entity with:
```
kubectl get secret tap-values -n tap-install -o jsonpath="{.data['tap-values\.yaml']}" | base64 -d | yq '.tap_gui.app_config.app.baseUrl'
```

(Optional) VMware recommends creating api-auto-registration-values.yaml.

To overwrite the default values when installing the package, create a api-auto-registration-values.yaml file:

tap_gui_url: https://tap-gui.view-cluster.com
cluster_name: staging-us-east
ca_cert_data:  |
    -----BEGIN CERTIFICATE-----
    MIIFXzCCA0egAwIBAgIJAJYm37SFocjlMA0GCSqGSIb3DQEBDQUAMEY...
    -----END CERTIFICATE-----
sync_period: 2m

Install the package using the Tanzu CLI:

tanzu package install api-auto-registration
--package apis.apps.tanzu.vmware.com
--namespace tap-install
--version VERSION-NUMBER
--values-file api-auto-registration-values.yaml

Where VERSION-NUMBER is the version of the package you retrieved in the earlier step.

Verify the package installation by running:

tanzu package installed get api-auto-registration -n tap-install

Verify that STATUS is Reconcile succeeded:

kubectl get pods -n api-auto-registration

Verify that applying an APIDescriptor resource to your cluster causes the STATUS showing Ready:

kubectl apply -f - <<EOF
apiVersion: apis.apps.tanzu.vmware.com/v1alpha1
kind: APIDescriptor
metadata:
  name: sample-api-descriptor-with-absolute-url

  owner: test-installation
  location:
    path: "/api/v3/openapi.json"
    baseURL:
      url: https://petstore3.swagger.io
EOF

Verify that the APIDescriptor status shows Ready:

kubectl get apidescriptors
NAME                                       STATUS
sample-api-descriptor-with-absolute-url    Ready

kubectl get apidescriptors -owide
NAME                                       STATUS    TAP GUI ENTITY URL     API SPEC URL
sample-api-descriptor-with-absolute-url    Ready     <url-to-the-entity>    <url-to-the-api-spec>

If the status does not show Ready, you can inspect the reason with the detailed message shown by running:

kubectl get apidescriptor sample-api-descriptor-with-absolute-url -o jsonpath='{.status.conditions[?(@.type=="Ready")].message}'

Verify that the entity is created in your Tanzu Developer Portal: TAP-GUI-URL/catalog/default/api/sample-api-descriptor-with-absolute-url
