On Your Marks


Getting Started


Before we can deploy our first microservice-in-a-container or function-as-code into the Kyma runtime, we (administrators, that is), first need to set things up. In this article, we cover all the required steps starting with the documentation (always be prepared)

  • Prerequisites: subaccounts and entitlements

  • Create service instance

  • Assign role collections

  • Register SAP system(s)


The focus of the documentation is on using the SAP BTP Cockpit web user interface. In this tutorial series we will also show you how we can achieve the same result using the SAP BTP CLI (command line interface).

The tutorial series assumes you have done your SAP BTP onboarding. If not, take a look at

BTP CLI


For the optional command line equivalents, you only need to be familiar with the basics.
btp help

btp --info

btp login

btp target

For the BTP command line tool, see

Subaccounts and Entitlements


Video Tutorial


In this video tutorial we provide an introduction to the SAP Business Technology Platform, Kyma runtime (SKR), covering the requirements for the runtime: subaccounts and entitlements using the SAP BTP cockpit console and the SAP BTP CLI.

4:20 - Assign accounts entitlements using BTP CLI

BTP CLI Commands


To create subaccounts
# create a subaccount

# regions: ap, br, ca, eu, jp, us, 

# providers: 10 (aws), 20 (azure), 30 (gcp) 

btp create accounts/subaccount 

 --display-name cf-eu20 --region eu20 --subdomain cf-eu20-qwerty

To assign entitlements
# query subaccount ID(s)

btp list accounts/subaccount



# assign entitlements

# plan = aws, azure, gcp

btp assign accounts/entitlement 

 --to-subaccount xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx 

 --for-service kymaruntime --plan aws --amount 1



# list entitlements

btp list accounts/entitlement 

  --subaccount xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx

About the plans, see

For the available regions, see the SAP Discovery Center


The Kyma runtime was initially hosted from Azure data centers. In 2021, AWS and GCP were added. Note that the region where the Kubernetes cluster can be deployed may differ from the region where the subaccount was created, e.g. for GCP US Central (Iowa),

Create Service Instance


Video Tutorial


In this video tutorial we provide an introduction to the SAP Business Technology Platform, Kyma runtime (SKR) and create a service instance of the Kyma runtime using the SAP BTP cockpit and the BTP CLI.

7:00 - BTP CLI

BTP CLI Commands


Although we can pass JSON on the command line by escaping the double quotes with a backslash, using a file is recommended.

Name is a required parameter, region, and machine type are optional and default to the smallest type (in case of Azure a single type is available).
{

    "name": "give-the-cluster-a-name",

    "region": "europe-west3",

    "machineType": "n2-standard-8"

}

To create an service instance
# list subaccounts for ID

btp list accounts/subaccount



# create Kyma runtime

btp create accounts/environment-instance 

 --subaccount xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx 

 --environment kyma --service kymaruntime --plan azure 

 --parameters azure.json



# list all environment instances 

btp list accounts/environment-instance 

 -sa xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx



# get details for single environment instances 

btp get accounts/environment-instance <ID>

 -sa xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx



# delete an environment instance

btp delete accounts/environment-instance <ID>

 -sa xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx

 --confirm

Security > Role Collections


Video Tutorial


In this video tutorial we provide an introduction to the SAP Business Technology Platform, Kyma runtime (SKR) and show how to assign the Kyma Runtime Namespace Admin and Developer role collections to a user using the SAP BTP Cockpit and the BTP CLI. We also download the kubeconfig configuration file and access the Kubernetes cluster using kubectl.

3:20 - Download Kubeconfig

4:00 - Kubectl delete namespace

4:20 - BTP CLI

BTP CLI Commands


To (un)assign user to (from) role collections, the following commands can be used.
# list roles for subaccount

btp list security/role

 -sa xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx   



# list role collections for subaccount

btp list security/role-collection 

 -sa xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx   



# assign role collection to user

btp assign security/role-collection KymaRuntimeNamespaceAdmin___x_xxxxxx 

 --to-user e.g@sap.com 

 -sa xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx



# unassign role collection to useress

btp unassign security/role-collection KymaRuntimeNamespaceAdmin___x_xxxxxx 

 --from-user e.g@sap.com 

 -sa xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx



Kubectl Commands


To connect to the Kyma (Kubernetes) cluster, download the kubeconfig YAML file from the Kyma Dashboard. When using a non-default location, you can define the path to the kubeconfig file as environment variable (see references).
export KUBECONFIG=path_to/kubeconfig.yml

kubectl version --short

You can use the Kyma Dashboard web UI or the kubectl command line tool to create, change, and delete namespaces.

As a managed service, the Kubernetes and Kyma system namespaces are not accessible.
# namespace (ns)

kubectl get ns

kubectl describe ns

kubectl delete ns

Over the years, for the SAP HANA Academy, SAP’s Partner Innovation Lab, and à titre personnel, I have written a little over 300 posts here for the SAP Community. Some articles only reached a few readers. Others attracted quite a few more. For your reading pleasure and convenience, here is a curated list of posts which somehow managed to pass the 10k-view milestone and, as sign of current interest, still tickle the counters each month.
