What is the current behavior?
Graph Node is not able to connect to Anvil (Foundry node).

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.

Docker compose file:

version: "3.3"

services:
  chain-1337:
    environment:
      - MNEMONIC=$MNEMONIC
    container_name: chain-1337-test
    image: ghcr.io/foundry-rs/foundry:nightly
    entrypoint: 'anvil --chain-id 1337 --mnemonic "$MNEMONIC" --host 0.0.0.0 --block-time 3 --verbosity'
    ports:
      - "8547:8545"

  graph-node-1337:
    container_name: graph-node-1337-test
    image: graphprotocol/graph-node:v0.26.0
    ports:
      - "8010:8000"
      - "8001:8001"
      - "8020:8020"
      - "8030:8030"
      - "8040:8040"
    depends_on:
      - ipfs
      - postgres-1337
      - chain-1337
    environment:
      postgres_host: postgres-1337
      postgres_user: graph-node
      postgres_pass: let-me-in
      postgres_db: graph-node
      ipfs: "ipfs:5001"
      ethereum: "mainnet:http://chain-1337:8545"
      GRAPH_LOG: info

  postgres-1337:
    container_name: postgres-1337-test
    image: postgres
    ports:
      - "5432:5432"
    command: ["postgres", "-cshared_preload_libraries=pg_stat_statements"]
    environment:
      POSTGRES_USER: graph-node
      POSTGRES_PASSWORD: let-me-in
      POSTGRES_DB: graph-node

  ipfs:
    container_name: ipfs-test
    image: ipfs/go-ipfs:v0.4.23
    ports:
      - "5001:5001"

Run docker compose up then docker logs graph-node-1337-test.

Observe log errors:

Jun 07 20:10:25.324 WARN Trying again after eth_getBlockByNumber(0, false) RPC call failed (attempt #12) with result Err(failed to send request: error sending request for url (http://host.docker.internal:8545/): error trying to connect: tcp connect error: Connection refused (os error 111)), provider: mainnet-rpc-0

What is the expected behavior?

It should work. If I use trufflesuite/ganache-cli instead of Anvil, it works. I expect it to work with both platforms.

I first filed a bug with Foundry, more context here:

https://github.com/foundry-rs/foundry/issues/1868

Beginne damit, das bereitgestellte Docker-Compose-Setup auszuführen und die graph-node-Logs für die fehlgeschlagene eth_getBlockByNumber-Anfrage zu untersuchen. Vergleiche das Anvil-Setup mit dem funktionierenden Ganache-Setup und verfolge den von graph-node verwendeten Verbindungsendpunkt. Erledigt ist die Aufgabe, wenn graph-node eine Verbindung zu Anvil herstellt und die konfigurierte Chain ohne Verbindungsfehler indiziert.
