Deploy and connect the Commerce mock application to the Kyma runtime.

You will learn

How to create a Namespace in the Kyma runtime
How to deploy the Kyma mock application, which includes a Kyma APIRule to expose the API to the Internet

Prerequisites

GIT installed

The Kyma mock application contains lightweight substitutes for SAP applications to ease the development and testing of extension and integration scenarios based on Varkes. Together with SAP Cloud Platform, Kyma runtime, it allows for efficient implementation of application extensions without the need to access the real SAP applications during development.

Step 1: Clone the Git repository

View Full Instructions

Go to the xf-application-mocks repository. Within the repo you can find each of the mock applications and their Deployment files within the respective folder. The process outlined in the tutorial is the same for each, but focuses on configuring the Commerce mock.
Download the code by choosing the green Code button and then choosing one of the options to download the code locally.

You can instead run the following command within your CLI at your desired folder location:
```
git clone https://github.com/SAP-samples/xf-application-mocks
```

Step 2: Apply resources to Kyma runtime

Open the Kyma console and create the dev Namespace by choosing Add new namespace, providing the name dev, and choosing Create.
Open the dev Namespace by choosing the tile, if it is not already open.
Apply the Deployment of the mock application to the dev Namespace by choosing the Deploy new resource option, using the Browse option to choose the k8s.yaml file. Choose Deploy.

You can find the file at /SAP-samples/xf-application-mocks/commerce-mock/deployment/k8s.yaml.
Apply the APIRule of the mock application to the dev Namespace by choosing the Deploy new resource option, using the Browse option to choose the kyma.yaml file. Choose Deploy. The APIRule exposes the resource to the Internet.

You can find the file at at /SAP-samples/xf-application-mocks/commerce-mock/deployment/kyma.yaml.

Step 3: Open Commerce mock application

Open the APIRules in the Kyma console within the dev Namespace by choosing the Configuration > APIRules menu option.
Open the mock application in the browser by choosing the HOST value https://commerce.*******.kyma.shoot.live.k8s-hana.ondemand.com. If you receive the error upstream connect..., the application may have not finished starting. Wait for a minute or two and try again.
Leave the mock application open in the browser, it will be used in a later step.

Step 4: Create a System

In this step, you will create a System in the SAP Cloud Platform which will be used to pair the mock application to the Kyma runtime.

Open your global SAP Cloud Platform account and choose the System Landscape > Systems menu options.
Choose the Register System option, provide the name commerce-mock, set the type to SAP Commerce Cloud and then choose Register.
Copy the Token value and close the window. This value will expire in five minutes and will be needed in a subsequent step.

Step 5: Create a Formation

In this step, you will create a Formation. A Formation is used to connect one or more Systems created in the SAP Cloud Platform to a runtime.

Within your global SAP Cloud Platform account, choose the System Landscape > Formations menu options. Choose the Create Formation option.
Provide a Name, choose your Subaccount where the Kyma runtime is enabled, choose the commerce-mock System. Choose Create.

What is the function of a Formation? To configure a runtime. To pair an application to the SAP Cloud Platform. To connect one or more systems to a runtime.

Step 6: Pair an application

Navigate back to the mock application browser window and choose Connect. Paste the copied value in the token text area and then choose Connect. If the token has expired, you may receive an error. Simply return to [Step 4: ](Create a System) and generate a new token.
Choose Register All to register the APIs and events from the mock application.
