kustomize manager seems to not detect overlays/multiple kustomization files

[NINNiT]

What would you like help with?

I think I found a bug

How are you running Renovate?

Self-hosted

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

Gitlab - mend-renovate-ce 7.3.0-full / renovate v37.368.10

Please tell us more about your question or problem

We are struggling to get a working configuration for kustomize repos up-and-running.

Our renovate.json:

{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "extends": [
    "config:recommended"
  ],
  "kustomize": {
    "enabled": true
  }
}

Our file tree:

├── base
│   ├── deployment.yml
│   ├── kustomization.yml
│   └── service.yml
├── renovate.json
└── test
    ├── config
    │   ├── ...
    ├── ingress.yml
    ├── kustomization.yml
    └── namespace.yml

Our test/kustomization.yml file, containing the image:

---
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
  - ../../base
  - ingress.yml
  - namespace.yml
namespace: test
images:
  - name: spring-template-image
    newName: some.registry.com/apps/spring-template
    newTag: v1.0.1-beta.3
configMapGenerator:
  - name: spring-template-configmap
    envs:
      - ./config/config.env
secretGenerator:
  - name: spring-template-secret
    envs:
      - ./config/secret.env

Looking at the self-hosted renovate-ce logs, renovate seems to detect only the alphabetically first kustomiatzion.yml - which is in base/ and does NOT contain any image declarations:

renovate-app-renovate-1  | DEBUG: Matched 1 file(s) for manager gitlabci: .gitlab-ci.yml (repository=group1/group2/deployment/spring-template-kubernetes)

renovate-app-renovate-1  |          "total": {"fileCount": 1, "depCount": 1}
renovate-app-renovate-1  |        }

The dependecy dashboard also just lists gitlab-ci as detected managers.

We'd appreciate any help we can get! <3
Is this a bug or are we doing something wrong?

It's nothing to do with kustomize. The config:recommended preset includes a preset which ignores all test/examples folders by default: https://docs.renovatebot.com/presets-default/#ignoremodulesandtests
