- Introduce podAntiAffinity settings to avoid scheduling multiple Pods with the same app: taw label on the same node. - This is a soft requirement, meaning that if there are not enough nodes, Pods may still be scheduled on the same node. This change enhances the deployment strategy by improving availability and fault tolerance of the taw application.
