Method Details

decorateFlinkPod

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()
