Kubernetes Runs Your Services. Linkerd Gives You Control Over How They Communicate.
Managing service-to-service communication at scale is one of the hardest problems in modern microservices. Ultimate Linkerd for Kubernetes Service Mesh begins with the principles of microservice architecture and how Kubernetes orchestrates containerised workloads, before taking a deep dive into Kubernetes networking such as: Services, Ingress controllers, and the Gateway API. From there it introduces the service mesh concept — what problem it solves, how the sidecar proxy model works, and why Linkerd is the ideal cloud-native choice.
With the foundations in place, the book moves into hands-on Linkerd: its architecture, control plane, extensions, and CLI. You will enable automatic mutual TLS across your services, apply golden-signal observability using Prometheus, Grafana, Jaeger, and distributed tracing, configure service profiles, split traffic between service versions, and run controlled canary releases.
Real-world deployment patterns drawn from e-commerce and financial services follow, along with practical guidance on performance tuning for HTTP/1.1, HTTP/2, and gRPC workloads. The final chapter provides a structured troubleshooting methodology covering control plane, data plane, network connectivity, and security identity issues.
