Openshift extension not merging Deployment from project manifest into generated one

[gansheer]

Describe the bug

I am using the Openshift extensions. I have some parts of the openshift manifest that is created from an external tooling in src/main/kubernetes/openshift.yml than contains the following resources: Deployment, Service, Route (route.openshift.io/v1).

The manifest generated target/kubernetes/openshift.yml is invalid. It contains 2 Deployment resources. The extension can't manage to generate a manifest with the merged version of my Deployment resource and its own.

Expected behavior

Generates a manifest target/kubernetes/openshift.yml with a merged Deployment resource, without any duplicate.

This is working correctly with Kubernetes extension.

Actual behavior

Generates a manifest target/kubernetes/openshift.yml that contains 2 Deployments resources.
