SAP Community - SAP BTP, Kyma runtime

Is the side-by-side BTP training updated with new course content? Found some bugs

2024-12-04T14:31:33.080000+01:00

Looks like this course contents are updated with different business example.

from risk-management -> incident-management. Unfortunately, we cannot copy code to test by ourselves and demo exercises are not clearly defined. There are few more bugs in the new content.

How to copy code?

Is it announced anywhere that SAP BTP is going to update the course content?

Please guide on this. Thanks.

Handling SAP CAP Function Endpoints in Kyma API Gateway APIRule v2alpha1

2024-12-11T12:49:44.494000+01:00

I am working on an SAP CAP (Java) application deployed in the Kyma runtime. I’m using an APIRule (v2alpha1) to expose my endpoints via the API Gateway.

In SAP CAP, function endpoints looks like this: /api/ProductService/getProductsBySkuAndCountry(sku='201',country='in')

Here’s the relevant part of my APIRule:

apiVersion: gateway.kyma-project.io/v2alpha1
kind: APIRule
metadata:
  name: multiple-services-jwt
  namespace: cap-ecomm
spec:
  gateway: kyma-system/kyma-gateway
  hosts:
    - cap-gateway
  rules:
    - path: /api/ProductService/{**}
      methods: ["GET", "POST"]
      noAuth: true
      service:
        name: productv2-svc
        port: 80

Issue:

When I try to call the function endpoint, I get a 404 Not Found error. I believe this is due to how the APIRule path-matching mechanism works.
But if i change the path: /*, it works fine. But i don't want to do that.

How to handle this?

Thank you in advance for your help!

Simplest Way to Restore Resources After a Kyma Cluster Expires on SAP BTP

2024-12-12T16:36:48.334000+01:00

Hi everyone,

I’m using SAP BTP Kyma Runtime, and my cluster will expire soon. I don’t use Persistent Volumes,

my data is only in Kubernetes objects like Deployments, ConfigMaps, and Secrets.

Question:

What is the simplest way to transfer resources from the current Kyma cluster to a new one after the old cluster is gone?

I know Kyma does automatic backups for Kubernetes objects, but:

Can I restore these backups myself?
Is there a simple, SAP-recommended way to migrate resources?
Should I use a tool like Velero to manage backups?

Thanks for your help!

Custom Extension in an MDK App (Using Metadata Approach)

2024-12-30T10:36:02.481000+01:00

Hello Experts,
I am trying to create a custom extension for SSAM 2310. I followed this Create Extension Controls documentation, but I encountered a problem. My workspace contains two projects: one is the standard SSAM 2310 metadata, and the other is ZComponent(ZSSAM2310), where I have made all the modifications.

I created my custom extension within the ZComponent(ZSSAM2310) project. However, I am getting a 'Failed to find module' error with the specific extension location.

How can I resolve this issue? Could you please provide some insights or suggestions on how to create and access the extension from ZComponent in my SSAM application?

How to mashup and combine external entity with custom entity for BTP CAP?

2024-12-30T11:46:26.468000+01:00

I have constructed SBS application which consumes the external service data using destination from SaaS SAP system. Now I would like to use some custom properties of my own together with ready entity definition from external service. Unfortunately, I have error when I try to combine. Using "extend" or "extend projection" does not work either.

Is there anyway how to fix this issue? Thanks.

Entity definition:

entity getPromoCustom as select from ex.Promotions {

key promotionID,

promotionName,

};

extend getPromoCustom with {

salesOrg : String(4);

distChain : String(4);

};

Error:

Use ‘extend projection’ to add select items to the query entityCDS (compiler)(extend-query)

How to Edit and Annotate an Image in SAP MDK?

2024-12-31T08:05:41.358000+01:00

Hello SAP Community,

I have a requirement in SAP MDK where an image is displayed on a mdk page, and I need to:

Edit the image directly within the app.
Add inline annotations, such as text or highlights, on top of the image.

Is there any standard control or feature in SAP MDK to achieve this functionality? If not, are there any compatible NativeScript plugins or workarounds to implement this in SAP MDK?

Any guidance, documentation links, or examples would be greatly appreciated!

Thank you,

Can we upload a docker compose file to BTP Cloud Foundry?

2025-01-08T15:35:20.750000+01:00

I want to deploy a Chatbot application to Cloud Foundry of BTP. I have this application in a docker-compose.yml file which has five different services mentioned and all services are dependednt on each other. Basically, it creates five different container in Docker which eventually makes an application run on a defined port.

I would like to know if there is any possibility to deploy the application with Docker compose file?

Also let me know, if there is any other way to deploy such application.

Thank you

Optional parameters for OData Functions or Actions in cds definition (CAP with Java)

2025-01-16T13:16:43.578000+01:00

Hi Everyone,

I'm working on a BTP service using CAP with Java, and need some help with OData functions. Here's a simplified version of what I have in my `service.cds`:

function testfunction(id: String, secondparam: String) returns String;

The issue I'm facing is that both `id` and `secondparam` are required parameters. However, I want secondparam to be optional. Currently, if I omit `secondparam` when calling the function, I get an error.

Does anyone know how to make the `secondparam` optional in this case? Any guidance or examples would be greatly appreciated!

Thanks in advance! 😊

How to perform Remote Table Replication if the HDI Container is created from Kyma Environment?

2025-01-17T17:45:18.820000+01:00

Hi,

I want to perform Remote Table Replication and have successfully achieved this in the Cloud Foundry environment. However, my main goal is to perform the same for an HDI Container created in the Kyma environment.

The challenge I’m facing is that in the SAP HANA Cloud Database, when I navigate to Add Instance > HDI Container, I can only see containers created in the Cloud Foundry environment. The containers created in the Kyma environment are not visible, which eventually prevents me from setting up Virtual Tables and Remote Subscriptions.

Could you please guide me on how to achieve this?

Thanks,

SAP BTP Cloud foundry Java Heap dumps to SAP Object Store

2025-01-23T18:02:31.248000+01:00

Hi,

I am attempting to push Java heap and thread dumps to a persistent location for further analysis. Persistent storage is required if a container goes down and the Java Heap or thread dumps taken can be lost if container goes down. Following the steps provided in the blog below java heap and thread dumps are able to be taken but are stored locally within the container. It can be exported to a local machine but the files can be very large in GBs.

https://community.sap.com/t5/technology-blogs-by-sap/java-heap-and-thread-dumps-on-sap-btp-cloud-foundry/ba-p/13514382

Is there a known solution around sending these files to SAP object store or another persistent storage location?

Thanks,

Rishi

Kyma APIRule v2alpha1: MaxAge default causing an error in Terraform

2025-01-27T17:21:35.941000+01:00

Hi all,

I'm working to migrate my existing entries for APIRule v1beta1 to v2alpha1, and I've hit upon something that I think might be an issue with the default manifest coming from Terraform.

Below is my original version of the v1beta1 rule in our Terraform (since it's just a manifest it should map to the YAML directly):

resource "kubernetes_manifest" "api_gateway_seq" {
  depends_on = [
    kubernetes_namespace_v1.o11y, data.kubernetes_service_v1.grafana_service, kubernetes_namespace_v1.dns_management,
    kubernetes_manifest.istio_gateway
  ]
  for_each = local.gateways

  manifest = {
    apiVersion = "gateway.kyma-project.io/v1beta1"
    kind       = "APIRule"
    metadata = {
      name      = "seq-apigateway-https-${each.value.suffix}"
      namespace = kubernetes_namespace_v1.o11y.metadata[0].name
    }
    spec = {
      gateway = each.value.gateway
      host = "seq.${each.value.host}"
      service = {
        name = data.kubernetes_service_v1.seq.metadata[0].name
        port = 80
      }

      rules = [{
        path    = "/.*"
        methods = ["GET", "POST", "PUT", "DELETE"]
        accessStrategies = [{
          handler = "allow"
          config  = {}
        }]
      }]
    }
  }
}

And below are the modifications I've made to support v2alpha1 --

Updated "host" to "hosts" with an array of 1
Added namespace to service
Added noAuth = true

resource "kubernetes_manifest" "api_gateway_seq" {
  depends_on = [
    kubernetes_namespace_v1.o11y, data.kubernetes_service_v1.grafana_service, kubernetes_namespace_v1.dns_management,
    kubernetes_manifest.istio_gateway
  ]
  for_each = local.gateways # we have multiple gateways

  manifest = {
    apiVersion = "gateway.kyma-project.io/v2alpha1"
    kind       = "APIRule"
    metadata = {
      name      = "seq-apigateway-https-${each.value.suffix}"
      namespace = kubernetes_namespace_v1.o11y.metadata[0].name
    }
    spec = {
      gateway = each.value.gateway

      hosts = ["seq.${each.value.host}"]

      service = {
        name      = data.kubernetes_service_v1.seq.metadata[0].name
        namespace = data.kubernetes_service_v1.seq.metadata[0].namespace
        port      = 80
      }

      rules = [{
        path    = "/.*"
        methods = ["GET", "POST", "PUT", "DELETE"]
        noAuth  = true
      }]
    }
  }
}

However, when I attempt to apply the Terraform, I see:

> AttributeName("maxAge"): can't use tftypes.String as tftypes.Number

I can't find any reference to maxAge in any default YAML files I've seen, but it does seem like it factors into corsPolicy.

Is there an appropriate default I should be moving to here? Or is this an issue with the standard resource definition?

How to enable Cloud Identity Services for Kyma runtime

2025-02-18T10:48:23.134000+01:00

Hi experts,

I try to update an existing Kyma runtime using the SAP Cloud Identity Services as Custom Identity Provider.
I followed the blog Configure Custom SAP IAS tenant with SAP BTP Kyma runtime environment

So, I created a new namespace in my Kyma environment. Here I created a service instance using offering name "identity" and plan name "application" setting following parameters:

assertion-attributes:
  email: mail
  first_name: firstName
  groups: companyGroups
  last_name: lastName
  locale: language
  login_name: loginName
  mail: mail
  scope: companyGroups
  user_uuid: userUuid
default-attributes: {}
display-name: Kyma runtime
home-url: https://api.#######.kyma.ondemand.com
name: ias-kyma-#######
oauth2-configuration:
  grant-types:
    - authorization_code
    - authorization_code_pkce_s256
  public-client: true
  redirect-uris:
    - https://dashboard.kyma.cloud.sap
    - http://localhost:8000
  token-policy:
    access-token-format: default
    refresh-parallel: 3
    token-validity: 3600
subject-name-identifier:
  attribute: mail
  fallback-attribute: none
user-access: internal

Based on this service instance I created a service binding called "skr-ias-binding" with secret name "skr-ias-binding-secret" and following parameters:

{
  "credential-type": "NONE"
}

Once the service binding was provisioned I copied the ClientId and Url from the secret and updated the Kyma runtime using following JSON:

{
    "oidc": {
        "issuerURL": "https://ouriastenant.accounts.ondemand.com",
        "clientID": "########-####-####-####-############",
        "usernameClaim": "sub",
        "groupsClaim": "groups",
        "signingAlgs": [
			"RS256"
		],
        "usernamePrefix": "-"
    },
    "administrators": [
        "user1@mycompany.com",
        "user2@mycompany.com"
    ]
}

The Kyma runtime was updated successfully. And when I launch the dashboard I'm also asked to log in with my IAS user.

However, after login I see following error:

When I check the network trace within the developer tools of the browser I see lot of HTTP 401 errors telling me I'm not authorized. But when I decode the Bearer token attached to the requests I can see all my users details. The "sub" attribute of the Bearer token contains my email which is also configured to be an administrator of the Kyma environment.

Within the IAS admin console I can see the new application. From the configuration it looks good as also described in SAP Help:

Redirect URIs are set to "https://dashboard.kyma.cloud.sap" and "http://localhost:8000"
The grant types "Authorization code" and "Enforce PKCE" are checked (but no other grant type)
The Public Client is enabled

Did I miss a step?

regards

René
