Run Graph Node on LUKSO

There are two ways to launch a Graph Node: you can use Docker to run related images, or you can compile the Graph Node source code. The steps described in this document will only be run through docker.

The instructions provided have been verified on MacOS systems. Adjustments may be needed for other operating systems. The content of this guide is informational, based on third-party inputs. It's important to verify any information with the official Graph repositories (https://github.com/graphprotocol/graph-node/tree/master/docker).

Prerequisites

Before diving into setting up a Graph Node, you need to have the following installed on your system:

In this guide, you will learn how to run a Graph node against LUKSO. This guide can also be adapted for LUKSO Testnet.

Prerequisites

The first step is to clone the Graph Node repository:

git clone https://github.com/graphprotocol/graph-node/ \
&& cd graph-node/docker

Next, execute the setup.sh file. This will pull all the necessary Docker images and write the necessary information in the docker-compose.yml file. Make sure to have docker running.

./setup.sh

Once everything is set up, you need to modify the "Ethereum environment" inside the docker-compose.yml file, so that it points to the endpoint of the node you are running this Graph Node against. Note that the setup.sh file detects the Host IP and writes its value, so you'll need to modify it accordingly. Check Networks section for different options of rpc providers.

ethereum: 'lukso-mainnet:https://42.rpc.thirdweb.com'

ethereum: 'lukso-testnet:https://rpc.testnet.lukso.network'

The entire docker-compose.yml file should look something similar to:

version: '3'
services:
  graph-node:
    image: graphprotocol/graph-node
    ports:
      - '8000:8000'
      - '8001:8001'
      - '8020:8020'
      - '8030:8030'
      - '8040:8040'
    depends_on:
      - ipfs
      - postgres
    extra_hosts:
      - host.docker.internal:host-gateway
    environment:
      postgres_host: postgres
      postgres_user: graph-node
      postgres_pass: let-me-in
      postgres_db: graph-node
      ipfs: 'ipfs:5001'
      ethereum: 'lukso-testnet:https://rpc.testnet.lukso.network'
      GRAPH_LOG: info
  ipfs:
    image: ipfs/kubo:v0.17.0
    ports:
      - '5001:5001'
    volumes:
      - ./data/ipfs:/data/ipfs
  postgres:
    image: postgres:14
    ports:
      - '5432:5432'
    command:
      [
        "postgres",
        "-cshared_preload_libraries=pg_stat_statements",
        "-cmax_connections=200"
      ]
    environment:
      POSTGRES_USER: graph-node
      POSTGRES_PASSWORD: let-me-in
      POSTGRES_DB: graph-node
      # FIXME: remove this env. var. which we shouldn't need. Introduced by
      # <https://github.com/graphprotocol/graph-node/pull/3511>, maybe as a
      # workaround for https://github.com/docker/for-mac/issues/6270?
      PGDATA: "/var/lib/postgresql/data"
      POSTGRES_INITDB_ARGS: "-E UTF8 --locale=C"
    volumes:
      - ./data/postgres:/var/lib/postgresql/data

Lastly, to run the Graph Node, just run the following command:

docker-compose up

You should see logs related to the Graph Node syncing with the latest available block in the network.
