      public FlinkPod decorateFlinkPod(FlinkPod flinkPod)
      Description copied from class: AbstractKubernetesStepDecorator
      Apply transformations on the given FlinkPod in accordance to this feature. Note that we should return a FlinkPod that keeps all of the properties of the passed FlinkPod object.

      So this is correct: 

      
 Pod decoratedPod = new PodBuilder(pod) // Keeps the original state
     ...
     .build()

 Container decoratedContainer = new ContainerBuilder(container) // Keeps the original state
     ...
     .build()

 FlinkPod decoratedFlinkPod = new FlinkPodBuilder(flinkPod) // Keeps the original state
     ...
     .build()

      And this is the incorrect: 

      
 Pod decoratedPod = new PodBuilder() // Loses the original state
     ...
     .build()

 Container decoratedContainer = new ContainerBuilder() // Loses the original state
     ...
     .build()

 FlinkPod decoratedFlinkPod = new FlinkPodBuilder() // Loses the original state
     ...
     .build()
