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

• Getting Started: Running with Docker
• Getting Started: Running in Kubernetes

• add-steps/

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

• Making Things Faster by Adding More Steps

• consul/

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

• dcos/

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

• Getting Started: Running in DC/OS
• linkerd on DC/OS for Service Discovery and Visibility

• docker/

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

• ecs/

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