How can I implement blue-green deployment in a Kubernetes cluster?

Example Concept: In Kubernetes, blue-green deployment can be implemented using two separate deployments and a service that routes traffic. The service initially points to the blue deployment. When deploying a new version, you create a green deployment with the updated application. Once the green deployment is verified, you update the service to route traffic to the green deployment. This switch can be managed using Kubernetes labels and selectors, ensuring a smooth transition without downtime.
