Upgrade OCM to the latest version

[nexus49]

Summary

Upgrade the OCM (Open Component Model) K8s Toolkit to the latest version and migrate from the current Kustomize-based deployment to the official Helm chart.

Current State

• OCM K8s Toolkit: Deployed via GitRepository/Kustomization pointing to commit 0c8ad3c6f96172bd0b7c3e5385c4f859ad4e7043
• Controller Image: ghcr.io/open-component-model/kubernetes/controller@sha256:5e790dad020adcfd0793f249d177a28429ef22446def39c9286eab90c52175c1
• Deployment Method: Flux GitRepository + Kustomization in local-setup/kustomize/base/ocm-k8s-toolkit/flux-sync.yaml

Tasks

1. Migrate to Official OCM Helm Chart

• Replace the GitRepository/Kustomization deployment with the official Helm chart: https://github.com/open-component-model/open-component-model/pkgs/container/charts%2Focm-k8s-toolkit
• Create a HelmRepository resource pointing to oci://ghcr.io/open-component-model/charts
• Create a HelmRelease resource for ocm-k8s-toolkit
• Migrate custom patches from local-setup/kustomize/overlays/ocm-prerelease/ocm-k8s-toolkit-patch.yaml:
  • Custom CA certificate mounting
  • SSL_CERT_FILE environment variable
  • Controller concurrency settings
• Update local-setup/kustomize/overlays/default/kustomization.yaml to use new Helm-based deployment
• Update prerelease overlay accordingly

2. Configure Renovate for OCM K8s Toolkit Updates

Current renovate.json only tracks the platform-mesh component version. Add:

• Add custom manager for OCM Helm chart version in the new HelmRelease

3. Testing

• Run task local-setup and verify OCM controller deploys correctly
• Run task local-setup:prerelease and verify prerelease workflow still works
• Verify OCM Component/Repository/Resource reconciliation works
• Test component transfer and deployment flow
