You can deploy Ocean onto Ganache - a local Ethereum “network” that you run on your machine for fast iterations while developing your app. You can easily do that with Barge.
Barge is a shell script to help run Ocean components (Provider, Aquarius), which runs Ganache by default.
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).
The Connect-to-Networks tutorial has more information about connecting your wallet / app to Ganache.
