About:
Linkerd is a command-line interface (CLI) tool designed to manage and interact with the Linkerd service mesh. It allows developers and operators to install the mesh, view real-time metrics, debug services, and secure connections. The tool is essential for observing and managing microservices traffic within a Kubernetes cluster.

Key Features:

Install and manage Linkerd control plane
Secure mTLS connections between services
View real-time service metrics and topology
Debug live service requests and proxies

Use Cases:

Observing latency and success rates for microservices
Securing gRPC and HTTP traffic with automatic mTLS
Troubleshooting connectivity issues in Kubernetes

Alternatives:

Istio – Heavier resource footprint with a steeper learning curve, but offers more extensive feature sets.
Consul – Provides service discovery alongside mesh capabilities, often used in non-Kubernetes environments.
