KRiedelsheimer · ‎2022 Jun 30

We have a new code challenge for you as part of the Community Spotlight for the month of July. This time it's about setting sail for Cloud Native Island, where you will explore the treasures of Kubernetes, Containerization and the SAP BTP, Kyma runtime.

This thread is the place to share your experience with the challenge and your progress for the challenge. Feel free to ask any questions (technical or non-technical) and leave your comments.

We are very much looking forward to your ideas and contributions! 😃⛵

My week 4 submission:

URL: https://check-invoice-service.c-1e90315.kyma.ondemand.com/checkInvoice

You can invoke the command using curl:

curl --location --request POST 'https://check-invoice-service.c-1e90315.kyma.ondemand.com/checkInvoice' \
--header 'Content-Type: application/json' \
--data-raw '{
    "supplierId": "ccd955cbc7b3",
    "invoiceNumber": "0254863",
    "invoiceDate": "2022-03-02",
    "locale": "en"
}'

The check-invoice service is now running 10 pods...

My week 4 submission.

https://my-service.a2985eb.kyma.shoot.live.k8s-hana.ondemand.com/

I haven't been able to put much of a load on it. Pods increased to a maximum of 3.

KRiedelsheimer · ‎2022 Aug 02

You can try and change the deployment.yaml and increase the ReplicaSet property 🙂

Hi @KRiedelsheimer ,

Thanks for your reply. In my submission above, I used below command to configure Horizontal Pod Autoscaler. Isn't this enough to achieve the goal?

kubectl autoscale deployment my-service --cpu-percent=50 --min=1 --max=10

I have increased spec.replicas in deployment.yaml to 10 and this indeed increased the pod count. But this is rather static declaration and not scaling according to the load, right?

  name: my-service

    app: my-service

For week 2 I tried to deploy the same Python app that I deployed to CloudFoundry: https://blogs.sap.com/2022/06/09/sap-tech-bytes-cf-python-app-to-upload-csv-into-sap-hana-cloud-data...

It runs localy in my Docker container, but does not start when deployed to Kyma due to error "WebSocket connection to 'wss://loadfilemvp.c-0007af4.kyma.ondemand.com/stream' failed: WebSocket is closed before the connection is established.".

Is there any additional rule I need to include into deployment file to enable websockets? I searched documentation, but could not find it.
