Examples with V1OwnerReference io.kubernetes.client.openapi.models.V1OwnerReference used on opensource projects

Example 1 with V1OwnerReference

use of io.kubernetes.client.openapi.models.V1OwnerReference in project java by kubernetes-client.

the class DeploymentHelper method listReplicaSets.

/**

 * attempt to reconcile ControllerRef (adopt/orphan), because only the controller itself should do
 * that. However, it does filter out anything whose ControllerRef doesn't match.
