Alternative fix for graph node setup issue

[dapplion]

Trying to run this repo locally I got stuck on yarn create-local due to the node being unable to connect to a local node (issue https://github.com/graphprotocol/graph-node/issues/1132). The proposed solution did not work for me and graph node was still unable to connect to the node despite using 0.0.0.0.

To fix it I included ganache as a service in the graph-node/docker/docker-compose.yml and reference it with the docker's internal DNS "mainnet:http://ganache:8545"

I've opened the issue in case this solution can be other users find this solution useful to setup.

# graph-node/docker/docker-compose.yml

version: "3"
services:
  graph-node:
    image: graphprotocol/graph-node
    ports:
      - "8000:8000"
      - "8001:8001"
      - "8020:8020"
      - "8030:8030"
      - "8040:8040"
    depends_on:
      - ipfs
      - postgres
    environment:
      postgres_host: postgres:5432
      postgres_user: graph-node
      postgres_pass: let-me-in
      postgres_db: graph-node
      ipfs: "ipfs:5001"
+      ethereum: "mainnet:http://ganache:8545"
      RUST_LOG: info

  postgres:

    ports:
      - "5432:5432"
    command: ["postgres", "-cshared_preload_libraries=pg_stat_statements"]
