serverless installs into a default namespace. why ?

[ptesny]

Description

serverless installs into a default namespace

Expected result

serverless installs into a kyma-system namespace

Actual result

serverless installs into a default namespace

Steps to reproduce
create a gardener cluster with the required shoot extensions
install OS kyma and then istion and api-gateway modules.

install serverless module

$ make serverless-deploy
kubectl create ns kyma-system --kubeconfig ~/.kube/kubeconfig--kyma--btp.yaml --dry-run=client -o yaml | kubectl apply --kubeconfig ~/.kube/kubeconfig--kyma--btp.yaml -f -
namespace/kyma-system configured
kubectl label namespace kyma-system istio-injection=enabled --kubeconfig ~/.kube/kubeconfig--kyma--btp.yaml
namespace/kyma-system labeled

kubectl apply -f https://github.com/kyma-project/serverless-manager/releases/latest/download/serverless-operator.yaml --kubeconfig ~/.kube/kubeconfig--kyma--btp.yaml

kubectl apply -f https://github.com/kyma-project/serverless-manager/releases/latest/download/default-serverless-cr.yaml --kubeconfig ~/.kube/kubeconfig--kyma--btp.yaml

@ptesny please adjust the line

kubectl apply -f https://github.com/kyma-project/serverless-manager/releases/latest/download/default-serverless-cr.yaml --kubeconfig ~/.kube/kubeconfig--kyma--btp.yaml

to

kubectl apply -f https://github.com/kyma-project/serverless-manager/releases/latest/download/default-serverless-cr.yaml --kubeconfig ~/.kube/kubeconfig--kyma--btp.yaml -n kyma-system

The bug is on your side as you want to install the serverless operator in a `system` namespace, https://github.com/kyma-project/serverless/blob/main/config/operator/operator/operator.yaml#L5 I think it is a typo, and you meant kyma-system rather, didn't you? PS. As other kyma modules install into `kyma-system` ns, you may want to amend the installation instructions: https://github.com/kyma-project/serverless?tab=readme-ov-file#install

Hi, the true value that kustomize uses is stored here https://github.com/kyma-project/serverless/blob/main/config/operator/default/kustomization.yaml , It's not a typo. Regarding the instruction good call, i will update the readme.md

[ptesny]

OK. so why the serverless module resources do not end up in kyma-system ?
Getting serverless in the default namespace is not good practice.
Other kyma modules do install to kyma-system
Thank you

The latest version of readme explains that serverless CR should be applied in kyma system namespace
https://github.com/kyma-project/serverless?tab=readme-ov-file#install

Other kyma modules ( istio, api-gateway ) do not have namespace scoped module CRs.
Serverless CR is namespace scoped and it installs in the same namespace where the CR is placed.

kyma-project/community#868 recommends to use static kyma-system namespace.
So there will be a follow up PR
