You can deploy Ocean onto [Ganache](https://www.trufflesuite.com/ganache) - a local Ethereum "network" that you run on your machine for fast iterations while developing your app.
**Barge** is a shell script to help run Ocean components (Provider, Aquarius), and. It can run Ganache optionally too (or connect to another network).
Barge launches Docker and Docker Compose, to run Ganache with Ocean smart contracts on top, along with Provider and Aquarius metadata cache. It's used extensively by the Ocean core devs (with Ganache or Rinkeby).
