## Linkerd - Kubernetes 服务网格课程总结 本课程介绍了 Linkerd，一款专为 Kubernetes 设计的轻量级、简单而强大的服务网格。它旨在无需代码更改即可为 Kubernetes 上的服务提供安全、可观测性和可靠性。 **核心优势：** * **超轻量 & 极简:** Linkerd 采用极简、Kubernetes 原生的设计，拥有极少的 YAML 和 CRD，易于理解和使用。 * **即时平台健康指标:** 无需额外配置，即可即时追踪每个服务工作负载的成功率、延迟和请求量。 * **零配置 mTLS:** 自动为所有集群内 TCP 通信添加 mTLS，无需任何配置。 * **专为工程师设计:** 拥有自包含的控制平面、可增量部署的数据平面以及丰富的诊断和调试工具。 * **即插即用的可靠性:** 自动提供延迟感知负载均衡、请求重试、超时和蓝绿部署等功能，增强应用弹性。 * **最先进的超轻量 Rust 数据平面:** 采用 Rust 编写的 Linkerd2-proxy 微代理，极致小巧、高速，兼顾安全与性能。 **工作原理：** Linkerd 通过在每个服务实例旁边安装超轻量、透明的代理来实现功能。这些代理自动处理进出服务的流量，充当高度仪表化的进程外网络堆栈。它们将遥测数据发送到控制平面，并接收控制信号。这种设计使得 Linkerd 能够在不引入过多延迟的情况下测量和操控服务流量。 **用途：** Linkerd 是所有从事微服务（尤其是在 Kubernetes 中工作）的开发者的必备工具。它简化了服务的运行，并提高了安全性。
A different kind of service meshUltra light, ultra simple, ultra powerful. Linkerd adds security, observability, and reliability to Kubernetes, without the complexity. CNCF-hosted and 100% open source.Instant platform health metricsInstantly track success rates, latencies, and request volumes for every meshed workload, without changes or config.Simpler than any other meshMinimalist, Kubernetes-native design. No hidden magic, as little YAML and as few CRDs as possible.Zero-config mutual TLSTransparently add mutual TLS to any on-cluster TCP communication with no configuration.Designed by engineers, for engineersSelf-contained control plane, incrementally deployable data plane, and lots and lots of diagnostics and debugging tools.Drop-in reliability featuresInstantly add latency-aware load balancing, request retries, timeouts, and blue-green deploys to keep your applications resilient.State-of-the-art ultralight Rust dataplaneIncredibly small and blazing fast Linkerd2-proxy micro-proxy written in Rust for security and performance.Linkerd is a service mesh for Kubernetes. It makes running services easier and safer by giving you runtime debugging, observability, reliability, and security-all without requiring any changes to your code.How it worksLinkerd works by installing a set of ultralight, transparent proxies next to each service instance. These proxies automatically handle all traffic to and from the service. Because they're transparent, these proxies act as highly instrumented out-of-process network stacks, sending telemetry to, and receiving control signals from, the control plane. This design allows Linkerd to measure and manipulate traffic to and from your service without introducing excessive latency.In order to be as small, lightweight, and safe as possible, Linkerd's proxies are written in Rust and specialized for Linkerd. You can learn more about the proxies in the Linkerd proxy repo.MUST TOOL FOR EVERYONE WHO IS WORKING WITH MICROSERVICES SPECIALLY WHEN WORKING WITH KUBERNETES
