linkerd 命令

常用示例

说明

linkerd is the CLI for Linkerd, a lightweight service mesh for Kubernetes. It manages installation, proxy injection, and provides observability tools for microservices traffic. The install command generates Kubernetes manifests for the control plane. Pipe output to kubectl apply for deployment. Use check to validate prerequisites and installation health. Sidecar proxy injection with inject adds the Linkerd proxy to pods, enabling mTLS, traffic metrics, and load balancing. Injection can be automated via namespace annotations. The viz extension provides observability features. The dashboard opens a web UI showing service topology and metrics. Commands like stat, top, and tap provide CLI-based traffic analysis. Linkerd uses mutual TLS by default, automatically encrypting traffic between meshed services without application changes.
