I am trying to patch this deployment with the provided patch. However, all I am getting is deployment.apps/database patched (no change), even though the volumes that should be added are clearly not added.
Tested this with plain old kubectl but this should primarily work through the Kubernetes Java API.
The JSONs seen here are taking directly from what the Kubernetes Java API generated.
The patchNamespacedDeployment operation is executed by a ClientBuilder.standard().setOverridePatchFormat(V1Patch.PATCH_FORMAT_STRATEGIC_MERGE_PATCH).build(), so this form of “adding” a volume should be absolutely supported and a valid operation.
How can I make this work?
