Moving away from patchesStrategicMerge to patches with multiple patches in one file

[juchom]

Hello,

I try to update my kustomize.yaml file, but it fails because I have multiple patches in one file.

It seems that this issue has been solved according to : #5049

I'm wondering what am I doing wrong ?

kubectl version

Client Version: v1.28.2
Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3

kustomization.yaml

apiVersion: kustomize.config.k8s.io/v1beta1

Error output

The issue is that I'm not using the right version of Kustomize.

This one contains the fix : https://github.com/kubernetes-sigs/kustomize/releases/tag/kustomize%2Fv5.2.1
