Deploying Ocean subgraph

About Ocean subgraph

Prerequisites

• A server for hosting Ocean subgraph. See this guide on creating a server.
• Docker and Docker compose are installed. Click here to view guide on installing docker.
• Ethereum API. Aquarius uses Ethereum api for monitoring on-chain events.
  Choose any api provider of your choice. Some of the commonly used are:
  • Infura
  • Alchemy
  • Moralis

Create a working directory

mkdir ocean-subgraph
cd ocean-subgraph

Create a `.env` file

Copy the below content into the `.env` file and edit the values as needed.

{% code title=".env" %}

ETHEREUM_NODE_PROVIDER_API='rinkeby:https://rinkeby.infura.io/v3/${INFURA_PROJECT_ID}'

{% endcode %}

Create docker-compose file

{% code title="docker-compose.yml" %}
