Getting started

Provides guides for getting linkerd up and running in multiple different environments, including local development, docker-compose, DC/OS, and Kubernetes. More information:

Add steps demo

Provides a self-contained docker-compose environment that can be used to test linkerd's performance. More information:

Consul

Provides a self-contained docker-compose environment which shows how to use consul as a service discovery back-end with linkerd.

DC/OS

Provides common configurations for deploying linkerd and namerd to DC/OS. More information:

Docker

Contains files and scripts for building custom Docker images that are used in some of the examples in this repo.

Amazon ECS

Provides common configurations for deploying linkerd to Amazon ECS. More information:

Failure accrual demo

Provides a self-contained docker-compose environment that can be used to test various failure accrual settings. More information:

Gob's microservice

Defines an example microservice application that uses linkerd and namerd to do staging, canary, and blue-green deploy.
