# Linkerd2-cni Helm Chart

Linkerd is a *service mesh*, designed to give platform-wide observability,
reliability, and security without requiring configuration or code changes.
The Linkerd [CNI plugin](https://linkerd.io/2/features/cni/) takes care of
setting up your pod's network so  incoming and outgoing traffic is proxied
through the data plane.

## Configuration
