🎈 Welcome to Linkerd! 👋

Linkerd is a transparent service mesh, designed to make modern applications safe and sane by transparently adding service discovery, load balancing, failure handling, instrumentation, and routing to all inter-service communication.

Linkerd (pronouned "linker-DEE") acts as a transparent HTTP/gRPC/thrift/etc proxy, and can usually be dropped into existing applications with a minimum of configuration, regardless of what language they're written in. It works with many common protocols and service discovery backends, including scheduled environments like Mesos and Kubernetes.

Linkerd is built on top of Netty and Finagle, a production-tested RPC framework used by high-traffic companies like Twitter, Pinterest, Tumblr, PagerDuty, and others.

Linkerd is hosted by the Cloud Native Computing Foundation (CNCF).

Want to try it?

We distribute binaries which you can download from the Linkerd releases page. We also publish Docker images for each release, which you can find on Docker Hub.

For instructions on how to configure and run Linkerd, see the user documentation on linkerd.io.

Working in this repo

BUILD.md includes general information on how to work in this repo. Additionally, there are documents on how to build several of the application subprojects:

  • linkerd -- produces linkerd router artifacts
  • namerd -- produces namerd service discovery artifacts
  • grpc -- produces the protoc-gen-io.buoyant.grpc code generator

We ❤️ pull requests! See CONTRIBUTING.md for info on contributing changes.
