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! 😃⛵

Hi Kevin,

Great to see Kyma in Community Code Challenge! Thanks!

The issue I'm having is that the image with the service seems to be missing in ghcr.io.

And the link to the Service Package in the Week 1 challenge leads to 404 page. This one:  https://github.com/SAP-samples/sap-community-code-challenge-cloud-native/pkgs/container/sap-communit...

VishnAndr_0-1657080818797.png

And the submission. The URL to some Coffee Corner thread in the Challenge Week 1 description leads to non-existing space :

Hi @VishnAndr ,

Thank you for letting me know. The link should be corrected and the package is public now (I forgot to change the visibility 🙈). Please let me know if there are still issues. 

Best,
KM

Hi Kevin,

Super interesting this challenge.

I pass the screenshots and url of the uploaded application (I didn't know that GitHub had a docker registry hehe)

Hi Experts,

To participate in this challenge, is it required to have SAP BTP Free tier subscription enabled?

Just BTP trial version is enough to work on the challenges? When I tried to subscribe for Free tier plan as an individual, it states for "India" free tier plan for individual is not permitted currently.

Thanks,

Vignesh.

Hey there - this docu resource should help https://kyma-project.io/docs/kyma/latest/05-technical-reference/00-custom-resources/apix-01-apirule#... 

example:

kubectl get crd apirules.gateway.kyma-project.io -o yaml

Hi DJ, thanks for the reply.

I tried the command but does not seem to return what I want.

Currently I can only see the url of the deployed service from dashboard. I wonder if I can get it using command line.

One way you could find this out is by looking at the virtualservices based on the deployment name and namespace, as follows (in this example, I'm assuming the namespace is default):

$ kubectl get deployments
NAME            READY UP-TO-DATE AVAILABLE AGE
hello-community 1/1   1          1         19m

This confirms that the deployment name is hello-community. 

Then you could use this (in conjunction with the namespace) to filter the virtualservices on the apirules label, and get the host this way:

$ kubectl get virtualservices -l "apirule.gateway.kyma-project.io/v1alpha1=hello-community.default" -o=jsonpath='{.items[0].spec.hosts[0]}'
hello-community.c-3d84dyx.kyma.ondemand.com

Hope that this will set you on the right path. 

Cheers
