Ocean Nodes

Ocean Nodes run everything you need in the Ocean stack, they replace three previous components: Provider, Aquarius and subgraph.

This is a minimal guide to quickly start and run an Ocean Node. See the docs directory for more detailed information on Ocean Nodes and how to customise your setup.

Note: this repository is currently excluded from all bug bounty programs.

System requirements

We recommend the following minimum requirements, although you may be be able to run a node with less (depending on your configuration).

• 1vcpu
• 2 GB ram
• 4 GB storage
• OS: we recommend using the latest LTS version of Ubuntu or the latest macOS. However, the nodes should also work on other operating systems including Windows.

Option 1: Running Ocean Nodes in Docker (recommended)

This readme is the recommended way to host a node and be eligible for incentives. The other options are more recommended towards developers that want to tinker.

Option 2: Running local build of Ocean Nodes in Docker

Run the following script to deploy node:

scripts/ocean-node-quickstart.sh
# OR
npm run quickstart

This command will run you through the process of setting up the environmental variables for your node.

Option 3: Running Ocean Nodes with PM2

PM2 is a process manager that makes it easy to manage and monitor your Node.js applications.

1. Install PM2

 npm install -g pm2

2. Setup the environmental variables

Either use the script:

npm run envSetup

or setup the required environment variables manually:

export PRIVATE_KEY="0x_your_private_key_here"

The PRIVATE_KEY is the only mandatory environmental variable, you must include the 0x at the front of your private key. Additional configurations can be set as needed. For all available configurations, refer to the Environment Variables documentation.

3. Quick start the Ocean Node with PM2

   pm2 start npm --name "ocean-node" -- run start

4. Monitor and Manage the Node

You can use the following PM2 commands to manage your Ocean Node:

pm2 list # View running processes
pm2 logs ocean-node # View logs
pm2 restart ocean-node # Restart the node
pm2 stop ocean-node # Stop the node
pm2 delete ocean-node # Delete the process

Option 3: Running Ocean Nodes With NPM

Prerequisites

• Node Version: Install the node version specified in .nvmrc.
• Docker
• Docker compose
• nvm (recommended but not necessary)

1. Start the Typesense database

docker-compose -f typesense-compose.yml up -d

2. Install dependencies & build the project

nvm use # Use the correct Node.js version
npm install # Install dependencies
npm run build # Build the Project

3. Configure Environment Variables

Option 1: Automatic Setup (Recommended)

Run the helper script to generate and set up the minimum required environment variables:

./src/helpers/scripts/setupNodeEnv.sh
source .env

Option 2: Manual Setup

Manually set the required environment variables:

export PRIVATE_KEY="0x_your_private_key_here"

The PRIVATE_KEY is the only mandatory environmental variable, you must include the 0x at the front of your private key. Additional configurations can be set as needed. For all available configurations, refer to the Environment Variables documentation.

4. Start the Node

npm run start

Your node is now running, the control panel will be available at http://localhost:8000/controlpanel/. To start additional nodes, repeat these steps in a new terminal.
