I have rather unusual issue with Kustomize and/or git.

I’m using kustomize with openshift and have following catalog structure:

├── bases
│   └── deployment.yaml
├── kustomization.yaml
└── overlays
    └── kustomization.yaml

Deployment is standard kubernetes’ deployment with following values:

- name: example
  image: kustomize_image

and overlays/kustomization.yaml:

images:
- name: kustomize_image
  newName: repo/image_name
  newTag: tag

And when I run kustomize build ./ | oc apply --dry-run=client -o yaml -f - to check if the values are correctly applied it looks OK, deployment’s image is replaces with repo/image_name:tag
BUT when I push those changes to remote git repository image substitution stops working. Instead of correctly assigned image:tag it leaves image: kustomize_image.

It works locally again when I change name of deployment and replicas: -name: in kustomization file.

This setup works correctly for other services that use the same setup. The only way I got this to work was hardcoding image in bases/deployment.yaml but it’s not ideal as I want those values to be changed in CI/CD pipeline.
