Deploying Aquarius

About Aquarius
Aquarius is an off-chain component with caches the asset metadata published on-chain. By deploying own Aquarius, developers can control which assets are visible in their marketplace. For example, having a custom Aquarius instance allows assets only from specific addresses to be visible on the marketplace. This tutorial will provide the steps to deploy Aquarius. Ocean Protocol provides Aquarius docker images which can be viewed here. Visit this page to view Aquarius source code.
Aquarius consists of two parts:
- API: The Aquarius API offers a convenient way to access the medatata without scanning the chain yourself.
- Event monitor: Aquarius continually monitors the chains for MetadataCreated and MetadataUpdated events, processes these events and adds them to the database.
Prerequisites
A server for hosting Aquarius. See this guide on creating a server.
Docker and Docker compose are installed. Click here to view guide on installing docker.

Create a working directory
mkdir Aquarius
cd Aquarius
Create a `.env` file
Copy the below content into the `.env` file and edit the values as needed.

After pulling all the asset metadata from the blockchain, Aquarius can be used to query the assets using Elasticsearch query. Aquarius REST API are documented here.
