Getting Started

Goal 🎯

This hands-on will combine many different SAP BTP services inside the SAP BTP, Kyma runtime. In this exercise we will prepare your SAP BTP account to walk through the hands-on session. Be aware that the preparation will require some time in itself.

⚠ NOTE: Not all services are available in all regions. In the case that a service is not available create an additional subaccount in the necessary region to add the service

Fork and Clone the Repository

Open the webview of the this repository. On the top right, choose the option Fork and choose your GitHub account.

Once the creation of the fork is complete, clone the repo in a directory of your choice and open it in your desired editor

git clone <your forked repository's clone url>

After opening the project create the folder credentials within the root directory of the project. This will be used to store files containing credentials which will not be tracked within your git repo as it is excluded via the .gitignore file.

Selecting the subaccount region(s)

On SAP BTP trial, only a subaccount in the region cf-us-10 works out for this tutorial. Trial subaccounts in cf-ap21 on MS Azure don’t include SAP HANA Cloud nor the SAP CICD service.

For the SAP BTP free tier, the recommendation is as well to use an AWS-based subaccount, but you can pick more regions. Kyma runtime in the free tier is only available on AWS. If you need to have SAP HANA Cloud on MS Azure, pick a region in which you can create a second subaccount with Kyma in the same region, e.g. Netherlands (Azure) and Frankfurt (AWS), Sydney (Azure & AWS), Tokyo (Azure & AWS), US East (Azure & AWS)

Configure Subaccount entitlements

In the SAP BTP global account choose Entitlements -> Entity Assignments. Choose your subaccount and choose Go. This will list all assigned entitlements.

Choose Configure Entitlements and Add Service Plans to select additional entitlements.

In the pop-up, choose the entitlements:

Entitlement	Plan
Alert Notification	Standard plan
Continuous Integration & Delivery	default (Application) or the trial (Application) or free (Application) plans which are not charged
Kyma runtime (if not yet entitled)	any available plan in the list (trial and free are not charged)
Launchpad Service (if not yet entitled)	standard (Application) or free (Application)
SAP HANA Cloud	hana
SAP HANA Schemas & HDI Containers	hdi-shared
Authorization and Trust Management	application

Choose Add x Service Plans in case you had to select any of the above and choose Save.

Kyma runtime

A detailed step by step can be found in the following tutorial

Provisioning

⚠ NOTE: The creation of the instance will take some time

In the overview area of your subaccount choose the option to Enable Kyma runtime. If the button for enabling Kyma runtime is not showing up, ensure that the entitlement has been set correctly.

Assignment of Roles for Kyma

After the enablement of Kyma runtime has finished, your user will be automatically added as an Admin of the Kyma runtime. See the Help Documentation for how to add additional users if necessary.

Getting the Kubeconfig for CLI access and preparing Kyma runtime

In the Overview area of your subaccount open the Link to dashboard link which appears next to the Console URL under the Kyma Environment area. At the top left of the window choose the Clusters Overview drop down and choose your cluster. In the Clusters Overview window choose the Download Kubeconfig for your Kyma runtime to download your KUBECONFIG.

Next set the kubeconfig to an environment variable:

• In a shell

  export KUBECONFIG={KUBECONFIG_FILE_PATH}

• In PowerShell

  $ENV:KUBECONFIG="{KUBECONFIG_FILE_PATH}"

Afterwards, ensure that it's working by creating the required namespace in Kyma via:

kubectl create ns cap

Launchpad service

Create Launchpad instance

Within your SAP BTP subaccount choose Service Marketplace. Select the Launchpad Service and choose Create.

Assign Launchpad role

Assign the role for the Launchpad Service by choosing Security -> Users in the subaccount. Then choose your user and the option Assign Role Collection.

Assign the value Launchpad_Admin to the user.

Cloud Foundry

In the Overview area of your subaccount choose the option Enable Cloud Foundry and choose Create. This will automatically add your user as CF Org Manager.

Choose the menu option Cloud Foundry -> Spaces and then the option Create Space. Provide the name dev and choose Create. (In a trial account the dev space should be available by default)

⚠ NOTE: The Cloud Foundry space is required to provision SAP Hana Cloud Database.

Continuous Integration & Delivery

PROVISIONING

Back in the subaccount, choose Service Marketplace. Select Continuous Integration & Delivery and choose Create. Use the default options choose Create.

ROLE ASSIGNMENT

Assign the role for the CICD Service by choosing Security -> Users in the subaccount. Then choose your user and the option Assign Role Collection.

Assign the value CICD Service Administrator to the user.

SAP HANA Cloud

⚠ NOTE: The creation of the instance will take some time. Also please note that when using the SAP BTP trial, the HANA instance will need to be restarted each day.

Instance creation

In the subaccount view, open Cloud Foundry -> Spaces and select the dev space and choose the menu item SAP HANA Cloud. Choose Create -> SAP HANA Database.

In SAP HANA Cloud Central, select as Type the entry SAP HANA Cloud, SAP HANA Database. Choose Next Step at the bottom right.

Provide the following values:

• Instance Name: teched
• Administrator Password: Any value

Chose Next Step and keep the default values of the next two screens by choosing Next Step twice.

On the SAP HANA Database Advanced Settings choose the option Allow all IP addresses and choose Next Step.

Lastly, choose Review and Create and then Create Instance.

Setup

⚠ NOTE: The step requires that the creation of the SAP HANA Cloud has completed.

Within your SAP BTP subaccount choose Service Marketplace and select SAP HANA Schemas & HDI Containers. Choose Create with the options

• Plan: hdi-shared
• Instance Name: cap-orders-kyma

Choose Create and select the option View Instance. Once the instance is created, open the instance and choose the option Create under Service Keys. Provide the service Key Name kyma and choose Create.

Once created choose the option View and copy the credentials.

Within the project open the file templates/vcap_services.json and create a copy of it saving it into the credentials directory of the project. Open the file credentials/vcap_services.json and replace the value <service key> of hana.credentials with the Credentials value for the SAP HANA property.

This means, the vcap_services.json will look like this:

{
  "xsuaa":[{
    "name": "cpapp",
        "label": "xsuaa",
        "tags": ["xsuaa"],
        "credentials":  <service key to be added in a later exercise> ,
  }],
  "hana": [
    {
      "binding_name": null,
      "credentials":  {
        "host": "{host}",
        "port": "443",
        "driver": "com.sap.db.jdbc.Driver",
        "url": "{url}",
        "schema": "{schema}",
        "hdi_user": "{hdi_user}",
        "hdi_password": "{hdi_password}",
        "user": "{user}",
        "password": "{password}",
        "certificate": "-----BEGIN CERTIFICATE-----{certificate}-----END CERTIFICATE-----"
      } ,
      "instance_name": "cpapp",
      "label": "cpapp",
      "name": "cpapp",
      "plan": "hdi-shared",
      "provider": null,
      "syslog_drain_url": null,
      "tags": ["hana", "database", "relational"],
      "volume_mounts": []
    }
  ]
}

Summary

🎉 Congratulations - Now you have setup all service instances and started preparing the VCAP service deployment. It's time to continue with Exercise 1 - CREATE THE XSUAA SERVICE INSTANCE
