If you’re want to try tsuru with a minimum effort we recommend you to use tsuru Now (or tsuru-bootstrap, that runs tsuru Now on vagrant).
tsuru Now will install tsuru API, tsuru Client, tsuru Admin, and all its dependencies and on a single machine. Including the docker node which will run deployed applications.
However, this is not the recommended approach for a production environment. This document will describe how to install each component separately.
We assume that tsuru is being installed on a Ubuntu Server 14.04 LTS 64-bit machine. This is currently the supported environment for tsuru, you may try running it on other environments, but there’s a chance it won’t be a smooth ride.
