In this video, you’ll learn everything about Kubernetes Deployments—how they work, why they sit on top of ReplicaSets, and how they make application management simple with features like zero-downtime rollouts, rollbacks, scaling, and self-healing. We’ll walk through YAML examples, key commands (kubectl apply, kubectl set image, kubectl rollout), and best practices to ace both real-world usage and certification exams.
