The guide provides a detailed walkthrough of implementing Kuma's new L4 traffic routing rules, which facilitate blue/green and Kubernetes canary deployments, designed to ease the introduction of new versions and features within a service mesh. Utilizing a sample marketplace application deployed on a Kubernetes cluster, the tutorial guides users through setting up the environment with Kubernetes, deploying the application across multiple pods, and integrating Kuma to manage network traffic without altering application code. It highlights the role of Envoy sidecar proxies in traffic management and demonstrates the gradual rollout of new features using the `TrafficRoute` policy, exemplified by a canary deployment scenario where different versions of the application are introduced incrementally. The guide underscores Kuma's user-friendly approach, requiring minimal operational overhead, and invites users to explore further features through Kuma's official resources and community channels.
