Kubernetes Deployment YAML files are crucial for safely managing rollouts and rollbacks, ensuring high availability with replicas, and auto-restarting stuck containers with livenessProbe. Pinning image versions and using readinessProbe can enhance traffic handling, while resource requests and limits guarantee and restrict usage respectively. Labels and selectors aid in organizing and controlling pods.
